Window air conditioners are affordable tools that will help beat the summer heat. These units are often smaller, easier to maintain and significantly less expensive than whole house central air conditioning systems, but that doesn’t mean they are maintenance-free. Fortunately, most of the care needed to keep your device pumping fresh air this summer can be done without professional help. Up front, we’re sharing how to clean a window air conditioning unit so you can make sure your machine is performing at its best.

How to clean your window AC unit

Your air conditioner will work the best when it is cleaned every year, and especially before when you need it most. “Wash the condenser coil with a water hose at slow water pressure to make sure you don’t kink the condenser fins,” suggests Brian Ludemann of Mechanical guess. Also, he suggests straightening the coil fins on the back with a fin comb ($ 9.99, amazon.com). Both of these tasks are best done every year (unlike filter cleaning, which he says should be done every month during your device’s operating months). “The best way to clean your air conditioner is to clean it on the outside,” he says. “This way you keep water and dust out of the house.” Just be careful when sliding the window out of the metal case, you don’t want to pull any electrical wires with it. Additionally, Ludemann suggests wearing rubber gloves (to prevent cuts) and safety glasses to prevent dirty water or dust from getting into your eyes. “

Don’t forget the exterior

After you’ve cleaned the interior parts of your device, you’ll want to take a look at the exterior. Truett says you can do this by washing your grill with lukewarm water and a mild detergent. “Another alternative is to use a damp cloth to wipe it off,” he says. “Once the grill has been cleaned, wipe down the top and sides of your appliance.” You’ll have to wait until all the rooms are completely dry before you turn your air conditioner back on, so save this work early in the morning or when you’re away from home for the day, that way you won’t. to be caught without AC when you need it most.

When to call the pros

Of course, the average homeowner can’t handle all aspects of air conditioner maintenance on their own, which is why Ludemann says you may need to bring in the professionals every now and then. For example, if your window unit won’t start, he suggests bringing in a professional. “[You should also call when you need] at check electricity go into the window air conditioning unit, ”he says, or if the compressor doesn’t seem to start and no cold air is being expelled. Regular maintenance will always be cheaper (and faster) than waiting around until you need to call a professional to help you, or have to replace your device all together.
