Your air conditioner is supposed to blow cool air to keep you comfortable during the hot summer months, so what should you do when warm air is coming out instead? Before you call an air conditioning service, see if you can figure out why your ac is blowing hot hair and you may be able to remedy the problem yourself. Here are the most common reasons:

You Need a New Filter

The filter in your air conditioning unit is designed to keep large particles and debris from blowing out your vents. However, when it’s old and clogged up, it can’t do its job as well. When that happens, proper air flow to the air conditioning unit is restricted, which can keep it from cooling the air. Simply changing the filter can often solve the problem.

Your Condenser is Dirty

Air conditioners require regular maintenance to keep them clean and in top working order. If the outside coils on your air conditioner are dirty or covered in dust, these tubes cannot properly cool the air in your home. Experts recommend cleaning your condenser at least once a year and making sure that bushes, plants and other things are at least two feet away from it to optimize air flow.

Check the Thermostat Setting

There are two settings on your unit. They are “on” and “auto.” When you have yours in the “on” setting, you are blowing air through the home, but not necessarily cooling it. When you switch it to “auto” the unit blows cool air based on the temperature reading in your house.

You Might Have a Leak

The part of your air conditioner that cools the air is the presence of refrigerant. If you have run out or have a leak, the air coming into your home isn’t going to be cooled. If you suspect this is the problem, a new can of refrigerant may be needed. In this case, it might be best to call in the pros to help you fix the problem properly.

As you can see, there are a few reasons why your air conditioner might be blowing hot air. Fortunately, the problem isn’t always one that requires a call to the professionals. You can often remedy the situation on your own. If you’re ever in doubt, an air conditioning expert can help.
