AC Unit Starts Blowing Warm Air

The last thing anyone needs in the middle of another sweltering hot summer is to lose their air conditioning. If your AC unit starts blowing out warm air, you may start to panic. You don’t want to pay for expensive repairs, and you know that repair rates will be really high in the summer, when demand is high.

Don’t worry. All hope isn’t lost just yet. There are a few different things that may be causing your issue, so it may not require expensive repairs. If your AC unit has started blowing hot air, then give these tricks a shot and see if you can get it fixed all on your own!

Check the Thermostat

This seems like a really stupid thing to tell someone to do, but believe it or not, it is actually the most common cause of air conditioners blowing out heat. Thermostats can often get bumped or incorrectly set. If your air conditioner is blowing out warm air, just take a peek and make sure that your setting didn’t end up toggled over to heat when you were trying to lower the temperature in the house. While you’re at it, check the temperature setting because it is also likely that you’ve got it set for warmer than you want it on extra hot days.

Do Some Cleaning

Air conditioning units often work by taking in normal air, and then using electricity to cool that air before blowing it back out into the home. If your air filter becomes clogged, then the unit will not be able to take in as much air. This can lead to it putting out warm air, or no air. Can you remember the last time you changed your air filter? If the answer is no, then it is probably time to go ahead and do that.

Along with the filter, condenser units can also become clogged or dirty pretty easily. Make sure that nothing is interfering with your unit’s ability to take in air. This means checking outside for dirt, tall grass, debris, and bushes. Remove any blockages and make sure all the moving parts are functioning.

Air conditioners also rely on coils to cool the air. These coils are what take in and dissipate thermal energy, resulting in cooler air output. If these coils are dirty, then they can’t perform their job well. This could be the reason your air ducts are releasing hot air. Make sure you check these regularly and clean them if they get dirty.

Call a Professional

If you’ve tried all of these things and your unit is still blowing out warm air, that means that the job is too big to handle on your own. More than likely, you have a leak somewhere or a duct that needs repairing, and you should leave this job to professionals.

One of the things you can do to save yourself some money is run tests in the spring and call for a consultation.
