Keep A/C Evaporator Coils Clean

One of the easiest ways to keep your air conditioner running at peak performance is to keep A/C evaporator coils clean. Your air conditioning system contains two types of coils: the evaporator coil and the condenser coil. Both are essential to the operation of the unit, and should be kept clean to maximize their efficiency. Follow these simple tips to keep them clean and reliable.

Both coils in your system manipulate the A/C refrigerant and help it get cold. The condenser coil is found on the outside of your house and is responsible for getting the refrigerant in the system to turn into a liquid. The evaporator coil is located deep within the ducts of your system and allows the refrigerant to expand into a gas and become very cold. Air is then passed over the cold evaporator coil and into your home.

You can take steps to clean the condenser coil on your own. It’s found on the outside of your house in the main A/C unit. The condenser coil depends on unrestricted airflow to do its job, so sweep away any leaves, dirt and other debris that’s collected around the unit. You can also carefully remove the casing of the unit and clean around the coil. Gently use a paintbrush to dust away dirt and debris from the fins around the coil.

In order to keep A/C evaporator coils clean, make sure to keep a clean filter in your system, checking it monthly and replacing it at the first signs of dirt. In a well-sealed system, most of the air that comes in contact with the coil will pass through the filter. If you keep the filter clean, the coil will remain clean for quite some time. However, dirt and dust is bound build up over time, and you should have a professional check the coil during your routine tuneup.
