Eliminate Frost From A Condenser Coil And Clean Its Surface

If the condenser coil in your window air conditioning unit has frost on its surface, debris may be trapped between the metal pieces. Learn how to eliminate the frost and clean the condenser coil so that the unit works properly.

Use The Following Materials

  • towels
  • hairdryer 
  • wet/dry vacuum cleaner
  • wire brush
  • fin tool
  • coil cleaner
  • lint free cloth
  • rust inhibiting spray
  • soapy water
  • scrub brush
  • filter

Melt The Ice And Remove Trapped Debris

Lay towels on the floor in front of the air conditioner. Turn off the power to the air conditioner and unplug it. Remove the front cover to the unit so that the condenser coil is exposed. It will take a while for the frost to melt off of its surface. You can speed up the process by heating up the front of the unit with a hairdryer. Once all of the ice has melted, use the hose on a wet/dry vacuum cleaner to suck up moisture on the condenser coil's surface. Use a wire brush to loosen debris that is stuck between the metal pieces.

Apply Coil Cleaner And Straighten Metal Pieces

Spray an even coat of coil cleaner on the condenser coil. This product will foam up after it is applied. Leave it on the surface for several minutes. Wipe the metal pieces off with a lint free cloth. If any metal pieces are bent, straighten them with a fin tool. Insert one end of the tool under the pieces that are bent. Press the tool firmly to bend the metal.

After all of the pieces are lined up properly, apply rust inhibiting spray to the condenser coil's surface. The spray will prevent rust from forming on the condenser, which could cause the unit to malfunction in the future.

Empty The Condensation Pan And Replace The Filter

Locate the condensation pan underneath the condenser coil. Pull it out and empty it. If the inside of the pan is dirty, clean it with soapy water and a scrub brush before replacing it. Inspect the filter and replace it if it is dusty. The filter is attached to the back of the front cover and slides right out. Reattach the front cover and plug the unit back in. Turn the power on. Cool air will blow out of the vents and you will no longer need to worry about ice forming on the condenser coil. Maintain the unit by cleaning the condenser coil whenever visible dirt is on its surface.
