With summer officially starting this month, the last thing you need is to run into an unexpected air conditioning problem on a 95-degree day! One of the easiest ways to keep your air conditioner around longer is to do some preventative maintenance on it every month.

Although your air conditioner is big and looks like it can take on just about anything, it still needs to be cared for! Cleaning it monthly is one of the best tips we could offer. The dirt and debris that gets caught up in and around your unit can hurt your indoor air quality and damage the unit itself. We recommend checking out your unit every month. But, before you do anything, make sure to turn off the power!

Next, you should remove any debris outside the unit. You can do this with a vacuum, or if it’s not too much then you can remove it by hand. After removing the outside debris, you’ll need to clean the inside. You can remove the top grille, and lift the fan out of your unit. Make sure you set it aside carefully as you clean out any dirt inside the fan.

After cleaning the fan, keep it set aside but make sure the electrical wires are not in the way. Next you’ll need to take your hose, and spray the fins (the side part of your unit). Make sure the pressure from the hose isn’t too high, but high enough to remove dirt and spray your unit from the inside out. After you’re done, place the fan back on and you’ve successfully cleaned your condenser!

In order to keep your unit as clean as possible, we recommend maintaining a two feet clearance around your unit. Be sure to trim any tree branches, flowers and make sure yours and/or your neighbor’s sprinkler systems are not hitting your air conditioning unit. Most of the preventative maintenance you can do on your air conditioner is recommended to be done by a professional, but we wanted to offer some tips that you can do at home, for free!

    Thanks for pointing out that you can clean the inside of an AC unit by removing the top grille and lift the fan out. My current unit wasn’t taken care of very well by the previous owners of my home, and it recently gave up. After working with air conditioning maintenance to get it fixed, I’ll be sure to regularly clean it right.

    I really like that idea of making sure you have a 2-foot radius of cleared spaced for your AC unit. I really like this will make sure that you aren’t getting any plants stuck in your unit. I live is an older home, and vines have started to grow my our AC unit. I’ll be sure to clear them off and make sure they keep their distance from it.

    Thanks for the tips on maintaining your air conditioning unit. I agree that keeping the area around the unit is really important so it doesn’t end up clogging the system. In my opinion, you should have a professional come out and look at the unit at least once a year to maintain it.

    My energy bill has been a little higher than usual lately. I mentioned this to a friend and he told me it could be because my air conditioning isn’t functioning properly and needs maintenance. I appreciate the tip in this article to clean to indoor and outdoor units at least once a month.
