How to Fix a Window Air Conditioner

Instructions for Fixing a Window Air Conditioner 1. Remove the front grill. Pry it off with a putty knife if it's held by clips, or use a screwdriver if it is screwed in place. 2. Unplug the air conditioner, slide it out of the window cabinet and set it on a sturdy table. You may need a helper to move the air conditioner if it's heavy. 3. Locate the mesh filter. It covers the radiator-like fins on the machine's evaporator coils. 4. Remove the filter, and wash it and the grill in a mixture of warm, soapy water and bleach--this will remove any mold. Shake out the excess water and set the filter and grill in your dish drain to dry. Air Conditioning Repair McComb 5. Vacuum the evaporator coils thoroughly, using a vacuum with brush attachment.

They are extremely delicate and bend easily. Air Conditioning Repair Mississippi
