• A dirty coil on the inside of the cooler can create many unintended issues – freezing, high
temperatures, high humidity, etc. Ensure that you have a scheduled maintenance plan in
place for cleaning the inside coil of your A/C. Recommended to be done at least once a
month.
• Dirty outside coils, motors, and other outside components of your A/C can lead to
premature failure, overheated compressor, loss of efficiency, poor cooling performance,
poor ventilation and all sorts of unintended problems. Ensure that you have a scheduled
maintenance plan in place for cleaning the outside coil and outside components of your
A/C. Recommended to be done at least twice a year*
• There are many videos available on “YouTube” explaining how to do a deep cleaning of a
window A/C (typically by removing it from the wall and placing it on a working bench).
Caution should always be used when cleaning A/Cs as to not splash any water in its
electronic components or use the wrong type of cleaners. Use common sense! If using a
professional Coil Cleaner -available at most hardware stores- please follow the
manufacturer’s recommendations. Watch Video on Cleaning the Inside Fins of Your A/C

• Inspect the door gasket for wear and make sure it seals tight against the Stainless-Steel
trim of the frame. Replace gaskets if worn or torn.
• Inspect the hydraulic door closer to ensure that it engages when the door is within an
inch or two and pulls the door tight.
• Inspect the door hinges and lubricate hinge pins with petroleum jelly as needed.
• Inspect the door sweep gasket at the bottom of the door for proper seal. Replace if
sweep is worn or torn.
• Check the door thermometer reading with another thermometer in the same location or
by placing the probe in to a cup of water with ice; it should read 32°F (0°C).
• Check for missing plugs and buttons and replace as necessary.
