How to Keep Your Window AC Unit Running Like New All Summer Long
June is right around the corner, and you know what that means: things are about to heat up! If you want to keep your cool in a heat wave, now is the time to clean up your window AC units. With a little TLC, they’ll run like new all summer long. Here’s how:
Clean or Replace the Air Filter
An AC window unit’s air filter traps dirt dust, pollen and other particles from the air and stops them from entering your home – but over time, the filter gets clogged, making your unit work harder to bring in outside air to cool your room. To avoid putting undue strain on your AC, you should replace air filters monthly... But the cost of replacing all those filters can add up quickly. Instead of buying brand new filters every time, try Frost King’s washable Air Conditioner Filter that can be used over and over all summer long. Just cut it to size and slip it into place; when it gets clogged, give it a quick rinse under running water and let air dry before reinstalling it. This video [link to “How to Install Frost King AC Filter” video here shows you how:
While the cover is off, wipe it down with a cloth dipped in soapy water, then rinse and let dry thoroughly. Complete the following steps (and leave the power off!) before replacing the cover and powering your unit back on.
Clean Evaporator and Condenser Coils
Your AC has two sets of coils—the evaporator coil in the front and the condenser coil in the back—that work together to transfer heat and humidity from inside the room to outside, but they can’t do their job efficiently if they’re clogged with dirt and dust. Use a coil-cleaning tool or a soft bristled brush to gently brush away any grime on the coils, or spray the coils with Frost King’s Spray Air Conditioner Coil Cleaner, a no-rinse detergent-based cleaner that easily washes away any dirt or grime. As you work, be very careful not to bend or damage the coils.
Clean the Drain Pan and Drain Lin
Your window AC unit has a drain pan and drain line that helps remove moisture from the air. If either gets dirty or clogged, water can back up and overflow into the unit or your home. After cleaning the coils, check the drain pan and line and use a wet/dry vacuum to clean away any debris. Reach hard-to-clean spots with a pipe cleaner or a tiny brush. Once the drain pan is clean, drop in an Air Conditioner Odor-Fighting Pan Tablet to prevent odors and build up from forming.
Check and Tighten Electrical Connections
As it runs, your AC unit is constantly vibrating, which can loosen electrical connections over time. Periodically check the unit for loose connections and tighten them with a screwdriver.
Lubricate the Fan Motor
While you’re checking the electrical connections, take a look at the fan motor. If it’s dry and squeaky, add a few drops of oil to the bearings or lubrication ports to keep the fan running smoothly.
Inspect the Unit’s Exterior
Once you've completed all the interior work, take a look at the exterior of your AC unit for any damage or signs of wear and tear. Check the AC unit’s side panels to see if they’re cracked or loose. If they are, they could be letting hot outside air flow around the unit and right into your home, making your AC have to work harder. Frost King has replacement side panels and foam panels that provide extra insulation and keep cooled air inside. You can also fill gaps around the top of the window sash, the sides, and the sill with our foam weatherstripping to maximize efficiency. Watch this video to learn more:
