Cleaning Your A/C Unit

Published by Steven Weiland

We got a taste of spring earlier this week, and before we know it we will be turning on our air conditioners to provide relief from the heat of spring and summer. When that heat arrives, you want to be sure your air conditioner is working efficiently, and you can help ensure this by cleaning coils or cooling fins.

Here’s what you will need:

  • A/C coil cleaner
  • Electric motor oil
  • Household cleaner
  • 4-in-1 screwdriver
  • Shop vacuum
  • Rags
  • Fin comb
  • Leather gloves

Clean the A/C by following these simple steps:

  1. Remove the plastic filter holder or trim panel. It generally snaps off relatively easily; however, it is heavy, so have another person help.
  2. If you have a window unit, remove the mounting frame and case by unscrewing them.
  3. Using your fin comb, comb out the mats my matching the end of the comb to the fin spacing. Insert the comb and pull up to keep fins straight. Be sure to wear your leather gloves during this step to protect your hands against cuts.
  4. Suck up spider webs, dust, dirt and any other debris from both coils with your shop vacuum.
  5. Spray the entire surface of both coils with foaming household cleaner and let the foam perform a deeper clean. Wipe away with a rag. If necessary, use a nylon-bristle brush to brush clean in the direction of the fins.
  6. Pop off plastic or rubber caps on the fan motor’s oiling ports and squeeze a few drops of electric motor oil into each. Secure the caps again once finished.
  7. Wash — or better yet, replace — your air filter. This should be done at least two times each year.
  8. Reinstall the unit.
  9. If problems persist, the unit may have a larger problem. Call Heatmasters for an inspection and repair.
