With the heat wave blasting all over the world, more and more people are looking to their AC units to keep things cool. It's imperative to keep them clean so that they don't blow contaminants around the room and lower the indoor air quality.

So, you've just moved into your apartment, and there's no central air. Instead, there's a handy window AC unit doing its best to keep your new space cool. You probably won't worry about it right away, but cleaning a window AC unit is a necessary task on the seemingly never-ending list of things to do when it comes to living on your own. Keeping an AC unit clean will ensure that it works properly, prevent harmful bacteria from entering your home, and stop any unwanted mold growth on the unit. Since sanitizing a window AC unit is one of those tasks you never, ever worry about until you have to do it, POPSUGAR reached out to experts to help answer the question: what is the best way to clean a window AC unit?

How Often Should You Clean a Window AC Unit?

Ideally, window AC units should be fully cleaned biannually. "You should deep clean a window AC unit twice a year," says Michael Rubino, president of HomeCleanse, council-certified mold remediator, and author of "The Mold Medic: An Expert's Guide on Mold Removal." "Clean it once before turning it on and once before shutting it down for the season." But this doesn't mean you should neglect the window AC unit on a day-to-day basis. Rubino suggests touching up your window AC unit as part of your daily routine to maintain it: "Owners should also take additional steps to clean the unit weekly and monthly as well."
