If you have a whole home air conditioning system, you’ve probably heard that your system has coils. What you may not realize is how important they are to your AC system. Your coils play a big role in the heat release/cooling process; anytime there’s any issue with the coils, your cooling will be affected. The AC experts at Bronco Plumbing Heating and Air can help keep your coils in great shape with annual maintenance. Just give us a call and schedule an appointment for your home in Roseville, CA.

Two Sets of Coils

Your AC system has two sets of coils: a set in the outside unit called the condenser coils and a set in your inside unit called the evaporator coils. The coils are stationary, serpentine-shaped tubes that are protected by thin aluminum fins. Each set plays a role in the heat release/cooling process in the following way: the condenser coils help the refrigerant in your AC system release heat as the refrigerant leaves the compressor and enters the condenser coils; as refrigerant flows into your evaporator coils, it is cooled down, so it absorbs the heat from your home, giving off cool air as it does.

Poor Maintenance = Problems

Your coils may not be the most mechanical of your AC’s components, but that doesn’t mean they can’t experience issues that will affect your cooling – they can. One of the most common problems that develops with air conditioning coils stems from a lack of maintenance: dirt and dust. Your coils attract dirt and dust, and if allowed to accrue, dirt and dust can turn into a layer that insulates the coils. This interferes with the coils’ ability to perform their job, and as a result, will affect your cooling.

Another problem that can develop within the coils is a refrigerant leak. Refrigerant leaks can be hard to find, especially in the coils, which is why it’s important to allow a trained expert to handle all of your AC repairs
