With temperatures on the rise globally, making sure your AC can handle whatever summer has in store is a must. Heatwaves can be especially hard on your AC, as the constant cycling combined with the higher heat exposure to the outdoor unit can be devastating for your AC. The following are a few ways that you can ensure your AC survives any heatwaves and keeps you cool.
Provide Some Shade
Shading the unit can help prevent it from overheating and malfunctioning during the hottest part of the day. A simple shade structure, whether it's permanent or simply a pop-up awning or shade cloth, will help. Just make sure the structure sits high enough above the unit so that air can move freely around the unit.
Replace the Filters
You likely know that your AC filters need to be replaced every month or two. You may want to change the filter a bit early, though, if you are expecting a heatwave. A fresh filter ensures that air flows smoothly through the unit with no blockages, which will take a lot of stress off the AC during hot weather.
Clean the Outdoor Unit
The outdoor unit can sometimes have leaves and other debris trapped inside, which could impede airflow and lead to overheating. Remove the housing from the outdoor unit and then use a shop vacuum to remove any debris that has collected inside.
Leave Your Fan On
Your thermostat can typically be set to "fan on" or "fan auto," with auto being the normal setting in many homes. When set to auto, the fan only comes on when the AC is running. If you leave the fan set to on, the fan will continuously circulate the air, which can help reduce the frequency that the AC needs to come on during a heatwave.
Check Your Vents
Blocked vents can cause an AC to cool poorly and work harder, both things you want to avoid during a heatwave. Check the vents, particularly the floor vents, in every room to make sure they are open. Move any furniture or drapes that are blocking the vents.
Lighten the Load
Don't make your AC work harder than it needs to. Turn on ceiling fans to help circulate and close curtains to keep out excess heat. Further, make sure all windows and doors are kept closed at all times.
