5 Tips For Cleaning Evaporator Coils

Evaporator coils are a critical component of your HVAC system. They provide the cooling for your home by capturing moisture from the air. If your evaporator coil is dirty, it will not be able to do its job efficiently. This can lead to problems like mold, mildew, and bacteria growth on the coils, which can then release into the air supply inside of your home. Keeping these coils clean is important to maintaining your indoor air quality and avoiding costly repairs. Here are 5 tips for cleaning evaporator coils.

How to remove the cover

For most evaporators, the cover can be easily removed with a screwdriver. Be careful not to damage or remove the screws from the housing that surrounds the coil. The cover will then need to be lifted up and off of the frame.

What tools you need

To clean your evaporator coils, you will need some tools:

– A vacuum cleaner

– A brush or rag

– Cotton balls or rags

– Distilled water

– A bucket

– Aluminum foil

How to clean with a vacuum

If you have a vacuum cleaner, you can use it to clean the coils. First, remove the grille at the front of the coil to reveal the coils. Then place your vacuum hose or tube against one of the fins and run it along all of the fins in that row. It is best to go from side to side when vacuuming, not up and down. Once you are done with one row, move on to another until all rows are complete.

How to clean with a brush and water

One of the easiest ways to clean your evaporator coils is with a brush and water. Mix 1 quart of water and 1 cup of white vinegar in a bucket or other container. Put on gloves, then dip the brush into the mixture and scrub the coils thoroughly. Rinse off the coils and dry them completely before turning your HVAC system back on.

How to use a scrubber

To clean the coils, you’ll need a scrubber. This can be something like a toothbrush or some other type of cleaning brush. It’s also important to make sure your scrubber is damp before you start scrubbing.
