Stay cool for many summers to come
Window air conditioner maintenance includes cleaning filters monthly, inspecting coils for ice buildup, checking drain pans for mold, and sealing gaps around your unit.
Your window AC needs deep cleaning before and after cooling season, plus monthly filter checks to prevent mold growth and keep your unit running efficiently.
Straighten bent coil fins with a fin comb, ensure your unit tilts slightly outward for proper drainage, and add support brackets for extra security.
Hiring a local window AC repair professional provides reliable help with filter replacements, coil cleaning, and yearly inspections that keep your unit running smoothly.
Window AC units are a lifesaver during those hot summer months. They are relatively inexpensive, easy to install, and get the job done. However, these appliances are subject to the passage of time, and single-room AC units are especially susceptible to issues. Stay ahead of malfunctions with this window air conditioner maintenance checklist.
These tools and materials won't break the bank and will help the unit last five to 10 years:
Replacement filters
Screwdriver
Soft-bristled brush
Clean microfiber cloths
Mild cleaning agent, like soap
Fin comb
Duct tape or weather stripping tape
Cover for the off months
You’ll need to complete several important maintenance tasks just before using the unit for the season:
Remove and clean the AC cover
Inspect the unit for insects, especially if you kept the unit uncovered in the window all winter
Thoroughly clean all components
Remove dirt and dust from the condenser coils
Inspect the coil fins and use a fin comb to straighten them out
Check the power cord for signs of wear and damage
Install the unit as instructed in the user manual
Ensure no components are loose
Check the condenser drain to make sure it’s free of debris
Ensure the AC is tilted slightly toward the outside
Install a support bracket for extra security
Test the unit at it’s lowest setting
Some tasks are worth checking off as you use the unit. Do these things every month to ensure the AC keeps on ticking:
Clean the air filter and let it dry before reinserting it
Check the filter for holes and rips
Replace the filter as necessary
Inspect the coils in the front of the AC for icing, as ice buildup could indicate a serious issue
Clean the window area surrounding the AC
Wipe down the unit’s exterior
Check for gaps between the window and the unit
Close gaps with duct tape
Check the drain pan, evaporator coil and ducts for mold
Complete the following steps before covering or storing the unit for the winter:
Deep clean with a damp cloth and a mild detergent
Remove and clean the filter
If covering the unit, make sure the cover is weatherproof but also allows a bit of airflow to prevent condensation
If storing the unit, find a dry location indoors
Window AC units benefit from some yearly maintenance tasks:
Hire a local AC repair pro for a proper inspection, especially if the unit is more than two years old
Test the unit at least once in the off-season
Look for the paperwork that accompanied the unit in case you need it for a repair call
