Posted on

Learn how to remove rust from your air conditioner's condenser coil and clean the other parts of its interior before placing it in one of the windows in your home. A clean unit that does not contain any rust will operate efficiently and keep your home cool throughout the summer.

Use The Following Items

  • coil cleaner
  • emery cloth
  • rust inhibiting spray
  • water
  • lint free cloths
  • fin tool
  • wire brush
  • vacuum cleaner

Remove Rust From The Condenser Coil

Remove the front cover on your unit by unclipping the sides and pulling it forward. The series of metal tubes that you will see underneath the cover are referred to as the condenser coil. This part is responsible for transferring warm air to cool air. Rub an emery cloth over the metal surface to remove rust. An emery cloth is a flexible tool that has fabric on one side and sandpaper on the other.

Wipe off the condenser coil with a damp cloth when you are finished. If the condenser coil is dirty, spray coil cleaner on its surface. Allow the cleaner to foam up for several minutes before wiping it off. Spray rust inhibiting spray on the condenser coil when you are finished to prevent rust from forming in the future.

Clean The Other Parts Of The Interior

Use the hose from a vacuum cleaner to remove dust and dirt from the rest of the interior parts of your air conditioning unit. Loosen dust or dirt that is stuck in small crevices with a wire brush. Wipe the interior parts of the unit off with a damp cloth. If any metal pieces are bent, a fin tool can be used to straighten them. Insert one of the corners of the tool under the bent metal pieces and push them back into shape. Replace the air filter in your unit if it is dirty. Reattach your unit's front cover and wipe the exterior off with a damp cloth. 

Keep The Air Conditioner Maintained

The air conditioner is ready to be installed in one of your windows. After you have set it up, plug it in and turn it on to make sure that it is working properly. Inspect and clean the unit's interior during the warmer months of the year. Be keeping the unit maintained, you will shorten the amount of time that it takes to clean it and it will continue to operate efficiently.
