UncategorizedKeep Your AC Coils Clean!


What’s more exciting than cleaning your house? Actually, probably almost everything. Even so, it’s something that needs to be done on a regular basis. But what about those areas or pieces of equipment that you overlook during regular cleaning? What about the coils in your air conditioning system? This isn’t something that needs to be done every time you vacuum the house, but it is important.

There are two coils you need to keep an eye on when it comes to your air conditioner. There’s one in the evaporator, which is in the indoor unit of your AC, and one in the condenser, which is in the outdoor condenser unit. Both of these play a huge role in keeping your home cool. If they are dirty or in disrepair, you’ll struggle to cool your Bremerton, WA home.

What They Do

Although evaporator and condenser coils are both important, they perform pretty much opposite tasks. The evaporator coil is where refrigerant is evaporated. The refrigerant draws heat out of the air so it can then be cooled and distributed throughout your home. When it’s time for the refrigerant to cool off, the condenser coil comes into play.

The outdoor condenser unit is covered with little openings and very thin strips of metal. These are the condenser coil fins. When the refrigerant passes through the condenser coil, it sheds heat and the refrigerant condenses. This is a basic summary of the refrigerant cycle that enables the necessary heat transfer to keep your home comfortable in the summer.

Why Are Dirty Coils a Problem?

It’s a big deal if there’s a bunch of dirt and debris on your evaporator or condenser coil. A dirty evaporator coil will have trouble absorbing heat from the air passing over it. This not only affects the cooling process, but can lead to the coil getting too cold. If that happens, condensation can collect and freeze up. That layer of ice will make the coil’s job difficult. This issue can strain the compressor, cause damage, and increase your energy costs.

A dirty condenser coil can cause your system to have a hard time releasing heat. This will burden the fan in the condenser while interrupting the flow of the ongoing refrigerant cycle.

If either of these coils are dirty, it can have an impact on cooling your home. During routine maintenance, your AC technician can clean these coils and straighten out the fins on your outdoor unit. You can do your part by keeping a fresh filter in your AC and keeping yard waste away from your outdoor unit.
