What Is the Best Temperature for a Heat Pump in Winter

Mon, 30 Jan 2023 12:00:51 GMT

Heat pumps are a convenient solution used year-round to both heat and cool your home. Due to their advanced technology, heat pumps are more energy-efficient machines than traditional AC units and furnaces. However, this technology also means that you must adjust to heat pumps differently.

So, the best temperature for a heat pump in winter is one that will keep you warm without wasting energy (thus costing you extra money on your electricity bills). Setting the temperature too low or too high can cause your heat pump to overwork, causing the price of your energy bills to increase drastically.

Today, the heating experts at Dr. Cool The Heat & Air Doctor will help you decide the best temperature for a heat pump in winter based on your everyday habits.

Tips to Choose the Best Temperature for Your Heat Pump in Winter

Here are the three steps to help you decide on your ideal winter temperature.

1. Understand the Mechanics of Your Heat Pump

The difference between traditional gas furnaces and heat pumps primarily lies in how the machinery distributes heat throughout your home. Gas furnaces use a blower to periodically push generated heat through your ductwork and into your home.

On the other hand, heat pumps constantly move air from outside to inside your home. As this air circulates through the heat pump, it becomes warm. Heat pumps are only energy efficient when outdoor temperatures are above freezing, as they must use extra electricity to heat the air when the temperature drops.

Thus, if the temperature has dropped below freezing and you have turned your heat pump on high, you could unintentionally increase the cost of your heating bills.

2. Know the Recommended Temperature for Heat Pumps

The Department of Energy has set up guidelines to help you save money on your heating bills. However, these are only recommendations to aid in your decision for the ideal winter heat pump temperature. Only you can decide what feels most comfortable and whether it is worth the extra cost.

The Department of Energy recommends that you maintain an ambient temperature of 68 degrees Fahrenheit during the wintertime. This is the most energy-efficient setting for your heat pump while still maintaining a comfortable indoor temperature.

3. Choose a Temperature and Leave It

Though switching the temperature on your thermostat as you enter and leave the house may feel tempting, you can raise your energy bills with this practice. Setting the temperature too low when you leave the house will cause your heat pump to work twice as hard re-warming the air when you get home.

Furthermore, heat pumps also have longer cycles than traditional furnaces. Thus, it takes them longer to warm up the interior air temperature, meaning they will waste more energy in the process.

Some homeowners use programmable thermostats for their heat pumps when they leave for work or vacation. When using a programmable thermostat, you should only lower the temperature by 7-10 degrees. Otherwise, you will waste more energy reheating the air than if you had left your heat pump at the same temperature as normal.

Tips to Help Reduce Your Energy Bills

Invest in regular repair service: Schedule regular maintenance appointments with Columbia's heat pump repair services . Maintaining your heat pump can increase energy efficiency and save money on costly repairs in the long run.
Use heavy-duty window coverings: Choose window treatments that will keep the cold weather outside. Window coverings should be heavy-weight and tight-fitting to prevent heat loss caused by cold windows.
Take advantage of the sun: If there are parts of your home that receive a lot of sun, open your blinds. This solar energy can warm your house, meaning you will save on heating bills.

Air Conditioner Low Air Flow: Top Causes and Solutions

Fri, 20 Jan 2023 12:00:24 GMT

Has cooling your home this summer taken longer than usual? Weak airflow may be the culprit. Often, air conditioner low airflow means that a component of your AC system has stopped functioning properly.

This malfunction will cause your unit to push less cool air into your home, thus failing to cool the space properly. Today, the experts at Dr. Cool the Heat & Air Doctor present the following guide on potential system malfunctions that may have led to poor AC airflow in your home.

Signs of Air Conditioner Low Air Flow

Here are three common signs that your air conditioner has an airflow problem:

Your vents have ceased to blow air (or the airflow feels weaker than usual).
You notice a pressure imbalance within your home (signs may include drafty areas and slamming doors).
There are warm and cool patches of air throughout your home.

4 Reasons and Solutions for AC Airflow Issues

Here are the four most common reasons for weak AC airflow:

1. Dirty Air Filter

When cooling the air inside a building, all AC units use an air handler to pull air from the atmosphere and into the unit. This air must then pass through a filter before the system pushes it into the space. Thus, if your air filter is excessively dirty, it can change the pressure of the air the unit pushes into the house.

This change in pressure can restrict air flow, causing uneven temperature distribution throughout the home.

Solution

If you have not changed your air filter recently, replace it. You should change your air filter once every 1-6 months (depending on your unit).

Alternatively, if you change the filter frequently, the air filter you use may be too thick. In this case, try a filter from a cheaper brand with thinner fabric.

2. Leaky Ductwork

Ductwork becomes cracked and damaged over time. This deterioration can allow air to escape, not only raising your energy bills but also creating airflow problems. Duct systems typically lose about 35-50% of the air meant to travel to vents, leading to air conditioners' low airflow.

Solution

You will likely need to invest in AC repair in Columbia if your ductwork is the problem. An expert AC contractor will come to your home to check the state of your ductwork, patch it, and/or replace problematic areas.

3. Blocked Ductwork or Registers

If you have registers located close to or on the floor, you may have accidentally blocked them with furniture or other objects. Blocking any vent can lead to reduced air flow, particularly if there is only one register located in the room where you have a cooling problem.

Alternatively, blocked air ducts can also lead to airflow problems. The ductwork that contractors failed to install properly may restrict airflow, as designers create duct runs to deliver a specified amount of air to a space of a particular size. If air must travel for a longer distance and more curves, it reduces the power of the airflow.

Solution

If you notice low airflow, check that all vents are unblocked and the slats on your registers are open. Ensure the outdoor unit remains unblocked, as debris can cause damage to the outdoor component. If you notice that all registers are open and your outdoor unit is clean, you may need a technician to come to check out the configuration of the ductwork inside your home.

4. Frozen Evaporator Coil

A functioning evaporator coil is essential, as this is the component of air conditioners that cools the air. Evaporator coils typically freeze due to obstructions in the blower fan or condenser, a malfunctioning motor, or low refrigerant levels. When an evaporator coil freezes, it can cause ice to form, thus creating an obstruction that restricts the airflow of the unit.

Solution

Though sometimes solving a problem with a frozen evaporator coil is as easy as changing your air filter or unblocking air registers, you will likely have to call the experts at Dr. Cool the Heat & Air Doctor. We will check your air conditioner, clear obstructions, and/or repair faulty components.

What Are Heat Pump Covers?

Heat pump covers refer to protective coverings that help keep your HVAC system clean during the winter season. Most heat pump covers for winter consist of all-weather vinyl material with insulating properties that help keep the system's components shielded from moisture buildup and debris caused by snow, ice, or rain.

Homeowners will also find other types of covers available, including retractable models they can easily remove once spring arrives.

How To Install a Heat Pump Cover?

The first step includes selecting the size cover for your heat pump. To do this, measure your unit and then match it with the appropriate cover size on the manufacturer's website or other sites that provide this information. Next, you'll use the supplied hardware to attach the cover to the unit.

If you need assistance, consult the manufacturer's instructions or contact your local HVAC experts. Once you install the cover, follow any additional instructions to ensure maximum performance. Be sure to install the cover properly to prevent damage to your heat pump.

Are Heat Pump Covers Necessary?

Although it may seem unnecessary to purchase a heat pump cover during winter, they prove very beneficial for protecting your equipment. Not only will a cover help to keep snow, ice, and rain from damaging your system, but it will also prevent pests from getting inside it. Pests can cause significant damage by chewing through wires, requiring expensive repairs to your system. A cover can help prevent this by allowing outdoor units to maintain proper airflow.

Heat pump covers for winter also provide crucial insulation to your unit, which will help keep it working efficiently throughout the winter months. Most units with a hard shell will require additional insulation to perform correctly. An insulated cover provides these benefits in addition to preventing damage to moving parts and preventing dirt and debris from getting inside your unit.

How To Choose the Right Heat Pump Cover for You?

Homeowners have a few different types of heat pump covers available to consider.

Soft Covers

The most common type of cover is an elasticized cover that fits over your unit like a tarp. This type of cover proves relatively easy to install and usually does not require special equipment. You can find these covers at most home improvement stores, typically at an affordable price. However, they are not very durable and will only last for a short time under heavy weather conditions.

Hard Shell Covers

Other types of covers include manufactured plastic covers that slide over the top of your unit. These covers provide better protection from extreme weather conditions and tend to last longer than a tarp cover. However, they are more challenging to install and are much more expensive than a standard tarp cover.

You can purchase these types of covers online at most appliance retailers or local hardware stores.

Which Type of Cover To Choose?

For homeowners who want to provide maximum protection to their heating equipment, hardcovers offer the ideal choice. Soft covers can provide temporary protection but will require replacement far more often. However, it's always wise to consult an HVAC professional before choosing a heat pump cover, as they can quickly determine which cover best suits your particular system.

HVAC Blowing Cold Air in the Winter: Should You Be Worried?

Tue, 20 Dec 2022 16:25:52 GMT

Many homeowners notice their HVAC systems performing differently during the winter. While your system may work less efficiently during the winter months, it is usually nothing to worry about. However, some instances may warrant a professional inspection.

This article will cover the most common causes of an HVAC blowing cold air in winter and how to address them. If you need further help with your heating or cooling, turn to Dr. Cool, Columbia's AC repair experts .

Causes of HVAC Blowing Cold Air

Your HVAC system may blow cold air in the winter for several reasons. The following sections will review some of the most common reasons, but you can contact the experts at Dr. Cool to find out the exact problem with your unit.

Insufficient Insulation

The most prominent reason stems from your home losing heat faster than your heating system can produce it. Most modern homes are well insulated and have heating and cooling systems that strive to maintain a consistent temperature throughout the house. However, the temperature will drop in a poorly insulated home as your heating system cannot keep up with the heat loss.

If you notice a difference between your thermostat settings and the temperatures in your home, you may need to look closer at the insulation throughout your house. When checking insulation, focus on the attic, basement, and exterior walls. Additionally, you may consider upgrading to a high-efficiency furnace to increase efficiency and reduce your monthly energy bills.

Clogged Air Filters

Another potential cause of the HVAC blowing cold air in winter is dirty air filters. The air in your home circulates through your air ducts to provide heating and cooling. If your filter becomes clogged, it can cause a blockage in your ductwork, which can prevent the system from circulating warm air through the house properly.

You may need to change the filter regularly to ensure that the heat exchanger can circulate clean air through your ductwork and maintain a consistent temperature throughout your home. If you have pets that shed a lot of hair or have small children, you should change your air filter more often than the recommended monthly schedule.

Blocked Ventilation

In certain cases, poor ventilation can also cause your HVAC system to blow cold air. For example, if the vents in the ceiling have furniture or other items over them, they may restrict the flow of air and prevent your system from working effectively. If they become partially blocked, it may be a good idea to rearrange your furniture to eliminate any restricted airflow. Finally, it may seem obvious, but checking your pilot light is also crucial, as it can disable your primary furnace burner if it goes out.

How To Address HVAC Cold Air Problems?

Wintertime can cause many problems with your heating and air conditioning systems. The extreme temperatures and cold wind outside can make the indoor air in your home uncomfortable and even unhealthy.

If these problems lead to your HVAC blowing cold air in winter, you need to address them quickly before becoming more substantial. Be we list some things you can try if you have problems with your heating or air conditioning systems.

Check Your Filters

One of the main causes of problems with your heating and cooling systems during the winter months can be dust buildup on your filters. This issue is particularly common if your heating system has been on for a long time since hot air causes the dust to accumulate over time. You can solve this problem by replacing your old filters with new ones or, temporarily, by cleaning the old ones.

Schedule an Inspection

Another way to prevent problems with your HVAC system concerns scheduling regular inspections and maintenance calls. This practice can help you avoid major repairs and keep your system running efficiently throughout the year.

Address Problems Quickly

Finally, it's a good idea to address any issues that arise quickly to prevent more significant problems from developing. For example, if your heating or cooling systems malfunction, call a technician as soon as possible to get the system up and running again.

11 Fall HVAC Maintenance Tips

Mon, 21 Nov 2022 02:35:14 GMT

Heating and cooling systems are complex and require periodic maintenance to work at their best. Dr. Cool The Heat and Air Doctor is the go-to company for AC unit repairs in Columbia, SC . We inspect, maintain, and repair all the common brands of HVAC components, and we pride ourselves on our comprehensive maintenance plans and our team of highly trained HVAC technicians.

Your furnace can encounter many problems during the winter. Be ready for them by taking preventative maintenance steps. These fall HVAC maintenance tips will give you confidence in your HVAC system this winter.

Avoid forgetting about your maintenance by calling Dr. Cool, The Heat and Air Doctor, to schedule regular maintenance. You and your maintenance technician can work together to follow the following fall HVAC maintenance tips.

1: Check the Detectors

Before you turn on your furnace in the fall, test your carbon monoxide and smoke detectors. Some potential heater, radiator, or furnace problems can cause toxic gases from the combustion chamber to escape into the air, reducing air quality, posing a fire risk, and potentially threatening the lives of everyone in your home.

2: Test the Furnace or Boiler

When the furnace is in operation, check for any unusual odors or noises that could indicate a problem with the furnace. A rattling sound could be a sign of a cracked heat exchanger. Other sounds could point to inefficient or incomplete combustion that could damage your furnace or boiler.

3: Calibrate the Thermostat

If the thermostat has a problem, your HVAC system might have trouble maintaining the temperature you want. A faulty thermostat can interfere with your ability to enjoy your home in comfort, force your HVAC system to work longer than necessary, and shorten its life.

If you have a smart or programmable thermostat, its diagnostic system might prompt you to schedule maintenance if it detects a problem.

4: Change the Filter

The HVAC system depends on being able to circulate air through your home. An old and dirty filter will spread dust, allergens, and bacteria throughout your house. The clogged filter will also strain your blower motor and cause your HVAC system to need more frequent repairs.

If you don’t know much about your HVAC system, ask the maintenance technician where to find the filters, what filters you need, and how often to replace them. The filter lifespan might vary according to the manufacturer and how often you use your HVAC system, but generally, you should change the filter every few months.

5: Inspect the Pilot Light

If you have a furnace that burns natural gas, look at the pilot light. It should burn a steady blue. If it won’t stay lit, looks yellow or orange, or flickers, ask your maintenance technician to check for a problem. Your maintenance technician should also inspect other components, such as the thermocouple, igniter, electrical system, and valves.

6: Check the AC for Refrigerant Leaks

Even though you probably won’t use your air conditioning for several months, have your maintenance technician check the refrigerant levels. If the system shows low refrigerant levels, your refrigerant line has a leak somewhere. It is better to identify the leak and fix it early rather than discover that your AC system has lost its refrigerant when you turn on your air conditioner in the spring.

7: Prevent Condensation Leaks

When your air conditioner runs, the evaporator coils pull heat from the air, causing condensation to form around the coils. The condensation collects in pans underneath the air conditioning unit and leaves through the condensate drain line. If the pan has cracks or the condensate drain line has a clog, water will spill onto the floor, potentially damaging the walls and equipment in the furnace room.

8: Check the Coils for Damage or Dirt

After keeping your home cool for several months, your air conditioning coils might be dirty. If dirt disrupts airflow around the coils, the coils might overheat or freeze. Any extreme temperature change can warp or damage the coils, which could reduce the air conditioner’s efficiency.

9: Clear Debris From Around the Outdoor Unit

Fallen leaves, grass clippings, and branches can interfere with the condenser coils in the outdoor unit and damage the fan blades. Keeping the outdoor unit clear of vegetation through regular maintenance will extend the lifespan and improve the performance of your air conditioning system.

10: Check the Air Ducts

Improve your air quality and the efficiency of your HVAC system by having a professional inspect and clean your air ducts every few years.

11: Winterize Your Home

One of the most effective ways to ensure that your HVAC system lasts a long time is to reduce its workload. Setting the thermostat to a higher temperature during the winter months makes a good first step. Winterizing the home will allow your heater to warm your home more quickly and reduce your energy bills.

In addition to keeping the HVAC system in good condition with our fall HVAC maintenance tips, you can prevent heat loss by:

Fixing any problems with the home’s insulation
Insulating plumbing to protect pipes and reduce wear on the water heater
Upgrading the heat retention capability of windows and doors
Disconnecting your garden hose and shutting off your sprinkler system

Homeowners can take many steps to keep their heating and air conditioning systems in good condition, but many fall HVAC maintenance tips require the assistance of a trained HVAC technician.

Air Conditioner Refrigerant Leak: Causes and Solutions

Thu, 20 Oct 2022 11:00:04 GMT

Our air conditioners keep us cool, especially during those hot summer months. Unfortunately, they can malfunction, and there's nothing worse than sweating profusely because your AC unit is acting up.

There can be many reasons why your unit isn't functioning correctly. One issue many homeowners face is an air conditioner refrigerant leak. Refrigerant, or freon, keeps your air conditioner running and your home nice and cool.

A refrigerant or freon leak can quickly make your home a sweltering nightmare. This blog will explore what causes refrigerant leaks and what you can do to resolve them. Expert AC repair services in Columbia, SC , can prevent leaks before they happen.

What Exactly Is Refrigerant?

Refrigerant, also known as coolant, is a chemical compound that exists as a gas or liquid. Here's how your HVAC system uses it:

An air conditioner's compressor squeezes refrigerant molecules and forces them to collide, producing heat
The refrigerant is then transported to the air conditioner's condenser, removing this heat
As the condenser extracts the heat, the refrigerant turns from a gas into a liquid
Finally, this liquid transfers through the evaporator coils, and cool air gets distributed throughout a room or home

An air conditioner refrigerant leak hampers an HVAC system's ability to perform and reduces a home's overall comfort.

What Can Cause Refrigerant Leaks?

An AC refrigerant leak can have various causes. We'll explore five of the most common:

Factory Defects

While appliances like air conditioners generally undergo a strict vetting process before hitting the shelves, factory defects can still happen. Factory defect causes include:

Poor assembly
Damaged components
Missing components
Improper handling (for example, a worker dropping an air conditioner)

Corrosion

Most HVAC systems feature metal parts and copper tube walls. Over time, copper corrodes, creating holes and cracks. When this occurs, refrigerant can start leaking.

Improper Installations

Sometimes homeowners will try to save money by installing an air conditioner themselves or hiring an unlicensed contractor. Unfortunately, this can cause issues. Even if an air conditioner appears correctly installed, ill-fitting parts can cause refrigerant to leak.

Weakened Connections and Joints

An AC's connections and joints can start eroding or thinning out. Even with the proper maintenance, this can occur simply because an AC unit is getting older.

Wear and Tear

Air conditioners are known for their durability. However, even if you limit an air conditioner's energy use and take good care of it, most units will only last between ten to 15 years. After that, components start to wear out, triggering a leak.

Signs You Have a Refrigerant Leak

Regular maintenance sessions with an expert HVAC team are the best way to spot and prevent a refrigerant leak. Besides a refrigerant leak wearing away at your HVAC system and damaging the earth's ozone layer, they can also create health risks.

We'll explore potential refrigerant leak signs to scrutinize:

Your Energy Bills Are Skyrocketing

It's common for your energy bills to skyrocket during summer or winter. Other factors like more people in the home can also cause higher energy bills. However, if you can't explain your higher energy bills easily, you may have a refrigerant leak.

When your AC unit leaks refrigerant, it must work harder to keep your home cool. Harder work equals higher costs.

You Have a Frozen Evaporator Coil

A frozen evaporator coil usually indicates you have an air conditioner refrigerant leak. You can check your evaporator coil, which generally sits behind the removable access panel of your indoor unit. Make sure to turn your AC unit off before checking.

You Have Warm Air Coming From Your Vents

An air conditioner pumping warm air may indicate a refrigerant leak or another issue. However, check your settings before jumping to the wrong conclusion.

It's possible you accidentally set your air conditioner to warm your home. Also, an air conditioner set to "auto" instead of "fan" can blow warm air.

You're Hearing Strange Noises

Hearing strange noises coming from your vents or directly from your air conditioner should always be a cause for concern. For example, rumbling noises typically mean a part is cracked or broken.

A hissing noise can signify that you have a refrigerant leak. These hissing noises come from cracks or holes inside your coils. Larger cracks can also produce a bubbling sound. Inspect your outdoor and indoor unit for any possible damage.

Higher Indoor Humidity

Your air conditioner not only lowers your home's temperature but can also combat humidity. However, less refrigerant means an air conditioner cannot properly remove hot air and humidity.

High humidity levels are uncomfortable, especially when trying to sleep. Excessive moisture can also attract pests and mold growth. So, you should inspect your HVAC system whenever high humidity becomes an issue.

What Should You Do When There's a Refrigerant Leak?

It's always best to resolve a problem the moment it occurs. However, sometimes a homeowner may not have to resolve an issue with their HVAC system immediately---as long as they still schedule an appointment with a technician.

That said, it's best to treat refrigerant leaks as emergencies, even if you're only experiencing a higher energy bill. Refrigerant leaking through your vents is a health hazard to you and your family. Inhaling coolant can trigger issues like dizziness and trouble breathing.

Some homeowners attempt to repair a refrigerant leak themselves. However, doing so can make the problem worse and void your warranty. Instead, you'll want to call Dr. Cool, The Heat & Air Doctor.

Our team can inspect your HVAC system at the first sign of trouble and determine if you have a refrigerant leak. Then, we can discuss options and provide a quick repair or a complete replacement.

What Is Freon, and Is It Important?

Sat, 20 Aug 2022 11:00:07 GMT

Air conditioning depends on chemicals called refrigerants. One of the most popular brands of refrigerants is Freon. The Chemours Company currently holds the trademark for Freon. So, instead of asking, “What is Freon?” a better question might be “What is the group of refrigerants that carries the Freon brand name?”

Dr. Cool, the Heat & Air Doctor, and his team of AC repair professionals in Columbia, SC , get many questions about Freon and other types of refrigerants, especially since the phasing out of Freon in 2020. We want to ensure that our customers understand the role of refrigerants and can make informed decisions about their air conditioning.

The History of Freon

Chemists at DuPont, together with General Motors, originally developed Freon to replace earlier refrigerants, such as ammonia. One of the most common types of Freon, dichlorofluoromethane, has the designation R-12. Other common refrigerants in air conditioning are R-22 and R-410a.

Manufacturers have used R-12, R-22, and other types of Freon in air conditioners and refrigerators and as propellants for aerosol products such as hair spray.

Characteristics of Freon

Freon is an effective refrigerant and propellant.

You might notice from the long chemical name, dichlorofluoromethane, that R-12 has chlorine, fluorine, and methane in its chemical structure. It belongs to a class of chemicals called chlorofluorocarbons, or CFCs. For decades, scientists have known that CFCs damage the earth’s ozone layer, among other environmental effects.

Freon has several properties that make it useful as a refrigerant.

It does not react with other chemicals and remains stable within an air conditioning system.
It converts easily into a gaseous form at a relatively low temperature.
It does not catch fire.
It does not smell bad and is not extremely toxic, although people should avoid contact with it.

Freon and Air Conditioning

One way to answer the question “What is Freon?” is to describe its role in air conditioning. The benefits of Freon become clear when you consider how refrigerant works in your air conditioner.

The goal of an air conditioner is to take heat from your home and convey it outside so that it can dissipate into the air a few feet away from your home. Freon works as a refrigerant because it absorbs heat when it turns into a gas and loses heat when it condenses into a liquid.

Refrigerant circulates through tubes between the evaporator coils inside the home and the condenser coils in the outdoor AC unit.

What Happens if Freon Levels Get Too Low?

The tubes containing refrigerant in home air conditioning units are airtight. Unless there is a leak, an air conditioner should not lose refrigerant. If your AC develops a leak, levels could drop to the point where the refrigerant cannot transfer heat efficiently.

Under low pressure, Freon might behave differently. It can evaporate too quickly, causing the evaporator coils to freeze, potentially damaging them. If refrigerant levels are too low, your AC will not be able to circulate cold air through your home.

Topping Off Freon

Regular air conditioner system maintenance extends its lifespan and keeps it running smoothly. During scheduled maintenance, the air conditioner technician will check the refrigerant levels, add refrigerant if needed, and fix the source of the leak.

The Environmental Effects of Freon

Freon leaks are more than just a drain on the efficiency of your air conditioner. They pose a risk to the environment as well. CFC refrigerants rise into the upper atmosphere and react with the ozone in the atmosphere, causing ozone depletion.

Ozone is an unstable molecule that consists of three oxygen molecules arranged in a triangle. When dangerous UVB light shines on our planet’s atmosphere, the ozone absorbs the light, preventing it from reaching us on the surface.

CFCs interrupt this natural process, allowing harmful ultraviolet radiation to get through. Increased UVB rays at ground level lead to skin cancer and other health problems for humans and animals.

The Phasing Out of CFCs in 2020

To protect the environment from CFCs, scientists and lawmakers have worked to limit and phase out the use of CFCs as propellants and refrigerants. In 1987, the world’s nations, including the United States, agreed to limit and phase out ozone-depleting substances, including CFCs. One provision of the Montreal Protocol is the phasing out of CFC Freon refrigerants by 2020.

As a result of the Montreal Protocol, new air conditioning systems won’t use CFCs as refrigerants. Healing the ozone layer saves millions of people from the increased risk of skin cancer. It also significantly changes the heating and cooling industry.

Alternatives to Freon

Chemists have developed alternatives to R-12, R-22, and other CFC refrigerants that are not toxic and do not contribute to the depletion of the ozone layer. One candidate for replacing older refrigerants is R-32, difluoromethane, which does not cause as much damage to the ozone layer as CFCs.

Upgrading Your Air Conditioning Unit

If you have an older air conditioning unit that uses a type of Freon as a refrigerant and still works, you don’t have to upgrade to a system that uses an alternative refrigerant. You can keep your old system. Just remember that manufacturers stopped producing new CFC refrigerants in 2020.

Throughout the 2020s, as supplies of older refrigerants dwindle, it might be harder or more expensive to top off Freon levels in older air conditioners. If your AC system is over ten years old, consider upgrading your system this year. Not only will it prevent you from worrying about finding Freon, but it will also save you money on energy bills.

What You Can Do as a Homeowner To Improve AC Efficiency

Wed, 20 Jul 2022 11:00:10 GMT

When the hottest summer temperatures hit, we all look forward to cranking up the AC and getting out of the hot sun. When you need relief from the oppressive summer heat, you want to ensure that your HVAC unit is operating correctly. Optimizing AC efficiency in your HVAC system is vital to maintaining a consistent comfort level without increasing your monthly energy bills.

Finding top-notch AC repair in Columbia, SC , is especially essential for southerners who endure some of the hottest temperatures in the whole country. Before calling a technician, explore some of the options below to improve your AC efficiency today.

13 Ways You Can Improve AC Efficiency Today

While hiring professionals to clean your unit routinely is one of the most effective ways to ensure AC efficiency year-round, these 13 easy solutions can give you a head start on improving your HVAC system's functioning.

1. Clean Around Condenser Unit

One of the quickest and easiest ways to improve efficiency in air condition systems, especially if you have a split system, is to clean the area around your condenser unit. Outdoor condenser units transform warm outdoor air into a cooling solution that lowers temperatures inside your home. Branches, debris, trash, and other obstructions can restrict the airflow into your condenser unit, limiting the efficiency of your system.

2. Clean Indoor Vents and Remove Obstructions To Airflow

Like cleaning the area around your condenser unit, cleaning your indoor air vents and removing any potential obstructions can help immensely. Wiping air vents with a wet cloth or cleaning solution provides clearer, more efficient airflow.

Removing obstructions increases air circulation efficiency and decreases the workload on your HVAC system. Together, this alleviates the load on your system while also improving airflow efficiency.

3. Use Ceiling Fans

Ceiling fans are a solution that requires nearly no additional energy. Airflow improves when air moves through your home rather than remaining stagnant.

Increasing airflow by running a ceiling fan while your AC is on reduces the load on the system and can even allow you to increase the temperature on your thermostat, which helps with AC efficiency in the summer. Ceiling fans take less energy than a lightbulb to operate.

4. Install a Whole-house Fan

Whole-house fans improve circulation to increase your AC efficiency by circulating warm air up and out of your home. While whole-house fans can be an investment, their efficiency improvements to your HVAC system might make them worth purchasing. Like ceiling fans, these fans also use very little energy.

5. Change Thermostat Settings

Changing your thermostat settings relieves pressure off your HVAC system and improves its energy efficiency rating. Since a system's efficiency ratings depend on how fast it can reach the desired temperature, turning the thermostat a few degrees warmer in summer or cooler in winter can improve functioning.

Temperature adjustments keep your seasonal energy efficiency ratio steady, as it will be easier to reach desired indoor temperatures if they align more with seasonal temperatures.

6. Change Air Filters

When air filters in your HVAC unit become dirty, your system's efficiency decreases. Although you should change your filters routinely, it's easy to forget and allow dirt to build up significantly. You could notice an immediate change in airflow productivity if you change your filters after a long period.

7. Avoid Placing Heat Producing Appliances Near Thermostat

Believe it or not, appliances that produce heat, like a stove, oven, or hair dryer, should never be near a thermostat. When thermostats detect heat from these devices, your HVAC system thinks your entire home is hotter. As a result, your AC stays on longer, working harder and less efficiently to cool your home.

8. Optimize Attic Ventilation

While it may not be your primary concern, improving the ventilation in your attic can significantly impact your AC efficiency. Because HVAC systems usually distribute air through homes via the attic, insulating your attic limits the impact of natural factors on your home's climate. Therefore, your AC runs better without extra hot or cold air interfering with your system.

9. Block Natural Light

While it's tempting to want to enjoy the summer sun's vibrant light indoors, covering your windows can help retain more of the cool air circulating through your AC system. Because the sun's glare can still heat your home, blocking windows and other natural light sources eliminates this impediment to an efficient HVAC system.

10. Clean the Drain Line

Keeping your air conditioner's drain line clean can improve AC efficiency. You can find the drain line on or near the AC condenser, where it removes excess moisture and condensation from the unit. Flush one cup of bleach and water down the drain line to maintain its cleanliness for the entire summer.

11. Stop Using Heat-generating Appliances During the Day

Using appliances that generate heat indoors during the day inhibits an optimally efficient HVAC system. Ovens, stoves, and even tea kettles generate excess heat that tricks your system into thinking it isn't adequately cooling your home. Wait until cooler nighttime temperatures to use these devices if your goal is to maximize efficiency.

12. Inspect for Air Leaks in Ductwork, Doors, and Windows

Air leaks within the ductwork of your HVAC system or through doorways and windows can redirect air inefficiently. Ideally, your air should flow directly through your system into desired rooms without redirection. Address any stray leaks to improve AC efficiency.

13. Schedule Regular Maintenance

One of the best ways to ensure a maximally efficient AC system is to schedule regular maintenance with experienced HVAC technicians. Regular checkups from a professional keep your system clean and functional and help catch issues before they become too severe.

The Benefits of Air Conditioner Coil Cleaning

Thu, 16 Jun 2022 18:15:40 GMT

Air conditioner coils are one of the most important parts of your air conditioning system. Air conditioner coil cleaning is a crucial part of making sure your whole system continues to work properly for a long time, pumping cool, clean air into your house.

Air conditioner coil cleaning isn’t something you should try to do on your own. The professionals in AC repair by Dr. Cool in Columbia are your safest bet for clean coils.

3 Benefits of Air Conditioner Coil Cleaning

Especially with summer approaching fast, you’re going to want to make sure your AC unit is running efficiently. If you’re not convinced you need to clean your air conditioner coils, here are some benefits of scheduling professional coil cleaning with an HVAC company like Dr. Cool.

1. Prolongs the system lifespan and lowers the risk of damage

Dirty buildup can cause the AC unit and the coils to work harder, making it more likely to break down completely. Coils covered with a layer of dirt and debris prevent heat from transferring effectively, causing your system to work harder, making its lifespan much shorter.

2. Clean coils can improve your air quality

It’s also important to consider how a clean and well-maintained AC unit affects your health. The air conditioner coils draw out warm air. If you have an outdoor unit, this can bring in dust, dirt, pollen, and other nasty debris that builds up in your unit. When this dirt gets into your air, dirt and pollen spread throughout the home, which can lead to breathing problems and allergic reactions.

3. Saves you money down the road

Keeping up with coil cleaning saves you money on system repairs down the road. It can also greatly reduce your energy costs. A faulty or dirty air conditioning system can also increase energy consumption by about 40% and can decrease the cooling capacity of your system by 30%.

Professional Cleaning vs. DIY Cleaning

Air conditioner coils are a delicate part of your AC unit, and cleaning requires special tools, specific cleaning products, and a practiced hand. Cleaning air conditioner coils yourself presents a higher risk for damage to the coils or other parts of your HVAC or AC unit.

If your DIY repair goes wrong, you’ll end up with more repairs and higher costs. When letting a professional handle it, you’re more likely to clean the unit quickly and properly.

If you try to take on the cleaning yourself and don’t know what you’re doing, no amount of YouTube tutorials can help you repair the damage on your own if you break it. Getting a professional to address any concerns and clean your system is the best way to maintain your AC unit and keep it running for a long time. A professional lowers the risk of damage, and they can also look out for anything else that might be wrong with your system that an untrained eye can’t see.

How to Tell If Your Air Conditioner Coils Are Dirty

Even if you clean your coils regularly, circumstances like weather, having pets, or recent construction work in your home can cause buildup on the coils more quickly. It’s important to look out for signs that your coils are dirty.

Some signs that you need an air conditioner coil cleaning include:

Your AC isn’t cooling your home effectively
Your air vents are pumping warm air instead of cool air
The AC unit is running longer than it normally does
There is frost or heavy condensation on your coils
Strange noises from the AC unit

While you can’t do anything to stop dirty coils from happening, there are ways your can slow down the process of buildup.

It’s important for your entire system that you change your air filters every two months and monitor for any problems, like leaks or decreased airflow. The quicker you see it and call someone to fix it, the better!

Types of Air Conditioner Coils

Your air conditioning system works with two types of coils: evaporator coils and condenser coils.

Evaporator coils extract the humidity and heat from your home. When air moves over the coil, it removes the heat. The hot air then travels to the condenser coil outdoors.
The condenser coils then work to expel that heat. Once the refrigerant compresses in the evaporator coil, it passes through the condenser coil, where the refrigerant vapor turns into a liquid.

This complex process relies on many parts in your AC unit. For fixing or cleaning these coils, you need to call in a professional who knows how to handle these delicate parts of your AC system.

Our devotion to service keeps your system running at peak levels throughout the year.

HVAC System Component Basics

It’s worth your while to learn more about the basic components that make up your HVAC system. By knowing more, you can spot potential problems when they arise.

Some standard AC system components include:

Refrigerant fluid
Condenser coils
Compressor
Thermostat
Ductwork
Expansion valves
Coolant lines

The AC unit pumps the refrigerant fluid throughout the entire system to produce cool air. As it travels through the network, the refrigerant picks up heat from inside the house and deposits this thermal energy outside. If any components supporting this process break, the entire cooling process can fail.

Common Summertime HVAC Issues

Your home HVAC unit suffers more wear and tear during the summer than at any other time during the year. It undergoes this wear because your residential or commercial HVAC unit runs almost continually during the hottest part of the year. Therefore, the continual stress on your AC components can cause one or several of them to fail.

However, HVAC component failure is not a foregone conclusion. If you pay attention to drops in HVAC performance, you can have an HVAC professional address the issue while it is still minor.

The following list includes some frequently seen summer HVAC problems:

1. Refrigerant Leaks

Refrigerant is the lifeblood of your HVAC system. It circulates through your cooling network and constantly changes from gas to liquid. During summer, when temperatures are high, your system stays on for extended periods.

When it’s hot out, the refrigerant must frequently go through its expansion and compression process. If any of your components are not up to speed, they’ll make a refrigerant leak almost inevitable. Even though leaks can be hard to spot, some usual-suspect areas include compressors, condensers, and transfer lines.

If you notice a drop in your system’s cooling capacity, you should schedule a service technician visit. The HVAC professional can quickly check your refrigerant levels with professional equipment.

2. Electrical Problems

Your residential or commercial HVAC system runs on electric power. As a result, it has large amounts of wiring running through the system. Other parts include logic controllers, breakers, and similar electrical devices.

If any of these wires break or malfunction, the entire system may stop working. Your AC also works overtime during the summer months to keep your house cool. If it has electrical power flow problems, it may experience surges and possibly circuit breaker activation.

If the switch for your AC system constantly trips, it's probably time to call the professionals.

3. Capacitor Overheating

Capacitors are electronic devices that store electrical energy and release it on demand. Your commercial or residential HVAC system likely has some capacitors in its electrical design. During the summer months, operating temperatures inside the unit paired with outdoor heat can overheat your capacitor.

If the capacitors overheat too much, they can completely fail.

4. Thermostat Malfunction

The thermostat is the nerve center of your residential or commercial HVAC system. Modern thermostats come in several levels of capability. These levels range from your basic programmable thermostat to cutting-edge smart thermostats.

Both programmable and smart thermostats let you set temperatures to your preferred settings. The smart thermostat takes this ability a step further by learning about your preferences and proactively activating or deactivating your system. Because the newer thermostat systems closely interconnect with this hardware, even small glitches result in a major drop in comfort.

5. Drainage Problems

During daylight hours in the summer months, your commercial or residential HVAC system may run continuously. As it does, it produces cold temperatures that, in turn, create moisture. This condensation usually flows out of the house through special channels.

However, if these moisture evacuation routes become clogged, water can back up and re-enter the home. If you notice excessive amounts of moisture flowing into the house from your AC unit, a clogged drainage line is likely the culprit .

6. Air Flow Blockages

If you have a central or ductless mini-split HVAC system, it has outside components like compressors and condensers. These components require air flow over their coils to provide cooling effects. However, during the summer months, plants and other types of foliage tend to bloom thickly around these outdoor units.

If such vegetation or other types of blockage collect around these sensitive components, they will impede airflow. As a result, the system will suffer efficiency problems.

At Dr. Cool The Heat & Air Doctor of Lugoff, SC, we can help you overcome all these HVAC problems and stay comfortable this summer.
