How Important Are Your Cooling System's Evaporator Coils?

Posted on

You have heard about the importance of changing and cleaning your air conditioner's filter, but there is another part that needs attention, too. The evaporator coils play an important role in the efficiency of your cooling system. To help you care for the coils properly, here is what you need to know.

Why Do the Evaporator Coils Matter?

There are two sets of evaporator coils. One set is located indoors and the other is outdoors. Both have different jobs.

The indoors coils has the job of allowing refrigerant to evaporate. They also absorb heat. This last function is particularly important because the outdoors coils releases heat. The release helps with heating your home in the cold weather.

When the coils are not clean, several problems can occur. One of the most common is the indoor coils will freeze. When they do, the cooling system will no longer cool the air. Instead of cycling on and off as it should, the cooling system will continue to run in an effort to reach the temperature set on the thermostat. This could mean high energy bills for you.

The increased usage of the cooling system can also mean additional wear and tear on it. The lifespan of your cooling system will be drastically reduced.

Can You Clean the Coils?

It is possible to clean the coils, but you should have an HVAC technician do it. He or she knows how to properly do it and can also examine your cooling system to determine if there are other problems with it.

If you do decide to take on the task, you have to be careful. You will need to locate the access panel on your cooling system to reach the coils. Refer to your owner's manual to find the panel. Once you have removed the cover from it, you can use compressed air to clean the coils. Use a vacuum cleaner to catch the debris removed.

For the outdoors coils, you can use a mixture of warm water and detergent. After applying the mixture to the coils, you can use a garden hose or spray bottle to remove the soapy water. Remember, to turn off the power to the outdoors unit before you start to clean the coils.

To ensure the evaporator coils are clean and to have your unit serviced before it is time to use it again, call your local HVAC technician.
