How an AC Contractor Cleans the Coils on Your Air Conditioner

If you’re like most Minnesota homeowners, you depend on your air conditioner to stay cool during hot, humid weather. However, if your AC unit isn’t regularly maintained and the coils aren’t kept clean, it may not continue to operate properly. Here are some basic guidelines for cleaning the coils on your air conditioner, along with the importance of having your unit maintained by a highly qualified AC professional.

BENEFITS OF CLEANING YOUR AC COILS

There are several advantages for keeping the coils on your air conditioner clean. One of the main benefits is having your AC operate at its best. Another perk is that cleaning the coils on a regular basis can save you on energy bills. In addition to paying less for energy costs, you’ll be less likely to pay for costly repairs or even having to replace your air conditioner. In other words, coil cleaning can extend the lifespan of your AC unit.

WHY COIL CLEANING SHOULD BE DONE BY A PROFESSIONAL

Since the coils in your AC unit are a vital factor for making sure your air conditioner runs efficiently, it’s best to hand over the job to a professional so that they don’t get damaged during the cleaning process. But it helps to understand the basic procedures used by an AC specialist so that you can better express any issues you may have with your HVAC specialist who cleans your coils.

METHODS USED BY AN AC CONTRACTOR

Commercial cleaning solutions

There are various commercial cleaning solutions used for cleaning coils on outdoor condensers. For example, there are foaming cleaners, which are formulated for coils on outdoor condensers. For indoor evaporator coils, self-rinsing cleaners are used, which are in the form of aerosol cans. They also come in low-pressure sprayers.

First, an AC contractor cleans off all surface debris, either manually or by using a specially-designed fin brush. Next, a commercial cleaner is applied, and the coil is rinsed with water, according to the instructions on the manufacturer’s label.

Cleaning the indoor evaporator coils involves cleaning any debris manually or with a specialized brush. This is followed by the application of a self-rinsing oil product, which efficiently cleans and rinses off the solution.

Mild household detergents and water

Another method is using a mild household detergent and water. After mixing the detergent and water, the solution is then applied to the AC coil, using a sprayer. The coil can be rinsed lightly by using a garden hose, or it can drain naturally. Only a low-pressure sprayer, rather than a pressure washer, is used. Consider how pressure should never be used because a high-pressure spray can cause damage to the delicate and thin metals of AC coils.

Don’t risk damaging your AC unit by trying to clean the coils yourself. You can depend on Minnesota Heating and Air Conditioning to do the job right Contact us and learn more about our wide range of residential and commercial HVAC services for Minneapolis/St. Paul residents.
