What’s An Evaporator Coil?

The evaporator coil is the part of your AC that absorbs the heat in your house. It is located inside the blower compartment or the air handler and holds the chilled refrigerant that is moved from the compressor. In an air conditioning unit, the air is blown over the coil and the refrigerant removes the heat. As the refrigerant removes the heat, it becomes warmer and goes back to the condenser coils. When heat is needed, this process is reversed.

HVAC Maintenance: Cleaning The Evaporator Coil

Having your evaporator coil cleaned is a basic part of air conditioner maintenance, whether your unit is residential or commercial. A dirty evaporator coil can lead to many issues, and oftentimes will make it seem like you are in need of a new unit. Sky HVAC knows better and won’t tell you that a new unit is needed until the evaporator coil has been checked and cleaned. Some common problems associated with a dirty evaporator coil can include:


  • Cooling efficiency – when this component of your system is dirty, it may seem like your air conditioner isn’t cooling your home properly. It can even lead you to believe that your AC has completely quit working


  • High energy bills – with a lowered cooling efficiency, your air conditioner is going to run non-stop yet never completely cool your home. When your unit runs non-stop and works that hard, it is inevitable that your electric bills will rise



  • Poor air quality – evaporator coils produce moisture and condensation. Dirt, debris, and dust will stick to the moisture. Over time, this buildup will allow for mold and mildew to grow and consequently be distributed throughout your home. If your family is constantly battling with asthma and respiratory illness, it can potentially be linked back to a dirty evaporator coil

Frequently Asked Questions

What is an evaporator coil and what does it do?


An evaporator coil is the air conditioner or heat pump component that absorbs the heat from the air in your house. It is positioned inside the air handler or attached to the furnace.


Why should I maintain my evaporator coil?


Dirt, dust, and debris on your evaporator coils makes it more difficult for your equipment to transfer heat. Since it is working harder, it uses more energy and reduces the lifespan of your AC components. Also, dirty coils can become corroded which leads to refrigerant leaks.


How can you tell if an evaporator coil is bad?


There are several indicators that your evaporator coil needs attention like: warm air from the vents; uneven cooling; frequent starts and stops; no power; refrigerant leaks; and abnormal noises near the cooling system (hissing or banging).

The Sky HVAC preventative maintenance program includes a 21-point inspection twice a year - once in the spring and once in the fall. We make sure your HVAC system is running at peak performance by checking amp draws, refrigerant levels, etc., which will save you on energy cost. We inspect critical components (motors, capacitors, condenser coils, and compressor) thus ensuring system reliability.


We will also conduct a full inspection of your duct system to make sure there are no air leaks that can be responsible for reduced airflow. An HVAC tune-up will ensure that your air conditioning system will be running as efficiently as possible and give your peace of mind!

As the summer heats up, you’ll naturally be using your air conditioner more and more. This is an effective way to beat the heat, but extensive use of your AC unit can cause wear and tear, or reveal existing problems. We at Sky HVAC want to help you and your family stay comfortable this summer, and to help you do that, our team has put together a list of signs to watch for in order to tell if you need air conditioner repair. Blows Warm Air - One clear sign that something is up with your air conditioner is warm air coming from your vents. If you put your hand by a vent and feel warm air, you probably need air conditioner repair. Makes Loud Noises - Another sign you should be wary of is loud or unusual noises coming from your AC unit. All air conditioners will make some noise as they run, but if you hear grinding, screeching, or scraping sounds from your unit, you should call our team at Sky HVAC to find out if you need air conditioner repair. Smells Bad - Your air conditioner is not supposed to stink. If you notice a bad smell coming from your unit when you turn it on, it’s likely that you need air conditioner repair. A musty smell usually indicates mold somewhere in your system, while a burned smell is likely the result of wire insulation burning out. If you notice any of these signs in your home or find something else unusual happening in your air conditioner, call our team at Sky HVAC. We’ll identify the problem and get your AC running smoothly as soon as possible.

Here at Sky HVAC, we specialize in all things air conditioning, and we want to help you stay cool this summer. Our team believes that the best way to help you take care of your air conditioning unit is to help you understand how it works. Knowing the principles behind your air conditioning unit will help you spot potential problems early and take care of them before they can become serious—or expensive. From our experts at Sky HVAC, here is a brief overview of how air conditioning works. Despite its association with cooling, the principle behind air conditioning is the transfer of heat. The typical air conditioning unit consists of an evaporator, a compressor, a condenser coil, and a fan. The evaporator is located inside the home, and contains a refrigerant that absorbs the heat energy from your home; as this happens, the refrigerant evaporates, hence the name. From there, the heat absorbed in the evaporator is transferred to the condenser coil, located in the exterior half of your air conditioning system. Also located outside with the condenser are the compressor and the fan. The compressor keeps refrigerant circulating throughout your system so that heat can be continually absorbed. Similarly, the fan keeps hot air moving out of your home. We hope that this article has been helpful to you. If you are experiencing problems with your air conditioning, or have further questions on how your unit operates, feel free to call our team at Sky HVAC.
