3 Common A/C Issues And How To Repair Them

Your central air conditioner will cool your home all summer long to prevent you from sweating while indoors and prevent you from needing to run fans or window air conditioning units in every room of your home. If your air conditioner isn't working, it can leave you scrambling to find these things to cool your home. If your air conditioner isn't working properly, you're going to want it working again quickly. Read on for a few common issues and how you can repair them.

1. No Cool Air

If your air conditioner isn't giving you any cool air, it's not running properly. Your air conditioner should be giving you nice cool air through your vents. If you aren't feeling cool air coming out of your vents, it may be due to a few different issues. You could have a lack of Freon in your unit, you could have your thermostat set wrong, or it could be an issue with a clogged air filter. To know for sure if you have enough Freon, you'll need to call a professional HVAC technician, as they are certified and trained to handle Freon. You can check your thermostat to be sure it is set to cool and that it is also set to a cool temperature. If the thermostat wasn't a problem, check the air filter and change it if it's full. The air filter should be changed every month.

2. Cycling Too Often

 If your air conditioner is running, turning off, and then quickly turning back on again, it's cycling too often. Your air conditioner should run until the temperature is reached, but it should turn on again when the temperature begins to rise in your home. If it's over-cycling, it could be because it is reaching temperature too quickly, which isn't going to cool your entire home. If your system is over-cycling, it may be because your system is too large for your home. If this is the case, you need a professional to take a look at your air conditioner, and they can tell you if it's the proper size for your home. If the system is too large, you'll need to replace it with one that is the right size. Using a system that is too large will eventually cost you a lot of money, and all of that extra running will lead to your system breaking down prematurely.

3. No Air At All

If your air conditioner isn't running at all, it may be due to the system being frozen. Your system's evaporator coil can freeze up, which will cause it to not work at all. It can freeze up when the refrigerant is low or when the air filter is dirty. Change the air filter if it's dirty and turn the air conditioner off. Run the fan only to your system to help thaw out the coil. Once it's thawed, turn the air conditioner back on and hit the reset button on the system. If this didn't repair your system, call a professional air conditioning repair service to check your refrigerant levels. 

These are just a few issues you may experience with your air conditioner. If you have a problem with your system and you aren't sure how to repair it, hire an HVAC technician for help to make the repair.
