When the weather turns hot in the summer, you want to keep your Charlotte County house nice and cool so that you are comfortable. But if your AC unit isn’t working properly, life can become unbearable. What causes air conditioners to stop working? Below are five of the main reasons why your air conditioner may not be working.

1. Refrigerant Leaks

You need to have so much refrigerant in your air conditioner so that it is able to work without any problems. If your air conditioner is low on refrigerant, this usually means that there is a leak. If you think this is the case, it’s a good idea to call an HVAC specialist to check your air conditioner.
​

2. Not Properly Maintained

Although your air conditioner is made to last you for years and work without giving you any problems, you will need to provide maintenance. It’s a good idea to have an annual checkup by someone trained in heating and cooling to make sure that your air conditioner is properly functioning. If you aren’t having this done, you may find that it’s not working properly and that you are having problems a lot more often.
​

3. Dirty Filter

If you find that your home’s air conditioner has stopped working all of the sudden and you haven’t had problems in the past, it might be that you need a new filter. Look at your unit’s filter and see whether or not it’s dirty. If your filter’s clogged or dirty, the air conditioner won’t work.
​

4. Broken Thermostat

There are times when the problem isn’t with the air conditioner but rather with your thermostat. If your thermostat isn’t properly working or if it’s not working at all, your unit’s not going to function either. Fixing or replacing your thermostat will more than likely solve your problem.
​

5. Sensor Issues

Caring for an air conditioner properly is going to keep it running and also help with keeping your energy bills down. The air conditioner’s cycles are based on your home’s sensor. This is the thing that keeps it at the right temperature. If it’s not working, your AC doesn’t know when it should turn off and on. The location of the sensor also can cause problems. If your sensor’s located in one of the smaller rooms in your home and you keep the door closed, the room’s temperature might hit the right temperature and this means your AC turns off. It’s a good idea for your sensor to go into your home’s largest room.
​
If your air conditioner isn’t working correctly, it is likely due to one of the above problems. Leaking refrigerant, a broken thermostat, a dirty filter, lack of maintenance, and problems with the sensor are all the most common reasons why an air conditioner isn’t working. If you aren’t sure what is wrong, it’s best to call an HVAC professional to give you advice. They will be able to diagnose the problem and get your air conditioning working or tell you what needs to be done.
