Why is it Important to Clean AC Coils?

Air conditioners contain many different parts, all of which complete a specific job as they work together to cool your home. Air conditioner coils are one of the more important parts of an AC, requiring maintenance to continue running properly. Let’s break down what AC coils are, why they’re important and how to take care of them.

What are AC Coils?

There are two types of coils in an air conditioner: the evaporator coils and the condenser coils. The function of these coils is to carry refrigerant between the indoor and outdoor units to cool the home.

As refrigerant runs through the evaporator coils, it removes heat from the air around it, becoming a hot pressurized gas. It then travels to the condenser coils outside, where it cools off and becomes a cool liquid once more. This process transfers heat from inside the house to outside the house, effectively cooling the air inside.

Why is it Important to Clean Air Conditioner Coils?

While the presence of AC coils may seem simple enough, they are incredibly important to the function of the air conditioner. Coils get dirty when dust and debris get into the AC system, usually due to a clogged air filter. The coils become coated in a layer of dust, which acts as a barrier between them and the air. 

This prevents the transfer of heat, which makes the refrigerant get so cold that condensation forms on the coils. The water clings to the dust and eventually freezes around the coils, causing the entire AC system to break down. 

How Often Should AC Coils be Cleaned?

You should have your AC serviced twice a year with a tune-up, during which the technician will clean your AC coils to prevent the air conditioner from freezing up. However, keeping your AC coils clean requires more than an AC cleaning every now and then. 

Remember to replace your air filter at least every two to three months, more if it’s really dirty when you replace it. This will keep dust and debris from entering your AC system and prevent your AC from freezing up in between tune-ups.

When it’s time for a tune-up choose Lee’s Air & Plumbing. Contact us today for more information or to schedule service.
