When the weather is hot, you want to make sure that your air conditioner is keeping your house cool. But what if it isn’t? What if your air conditioner is blowing hot air instead of cool air? Below are four common reasons why your air conditioner may not be cooling your house the way that it should.
This probably seems like a really dumb reason, but if you are getting air that is hot coming from your air conditioner, it’s possible that your thermostat has been accidentally set for heat. This happens to a lot of people. If this is the case, simply change it back to the cool mode and you’ll be ready to go.
So now you have checked your thermostat and hot air is still being blown from your air-conditioner. The reason might be your evaporator coil is dirty. This can be due to your air filter being dirty. If your air filter is dirty, this can keep the AC from cooling your house properly. The filter can be changed by you, but a professional will need to be the one to clean your evaporator coil.
Go outside and take a look at the condenser unit of your outdoor air conditioner. Do you notice anything that’s blocking the airflow of your condenser coil? Are debris and dirt blocking the coils? If they are, this is going to seriously impact the cooling ability of your AC unit. You want to make sure that your condenser coils are being cleaned regularly during the summer.
This final reason is usually the culprit. Your AC will need a proper refrigerant, such as Freon, charge in order to cool the home. That’s why it’s important that you make sure that you have enough refrigerant in your air-conditioner so that you are staying cool during the summer. One way to tell whether or not there’s enough refrigerant in the air conditioner is to see if ice is forming on the outside and inside units. You want to make sure that you’re calling a professional to have your refrigerant charged.
These are the common reasons why your AC unit may be blowing hot air. Take a look and see if any of these are the reasons why. If you can’t see a good reason for it to be blowing hot air, it’s a good idea to call a professional to have your unit looked at. It may need to be replaced, based on how long you have had your AC.
