why your ac is not cooling

With the Spring season approaching soon, it’s important to make sure that your air conditioner is in proper condition and devoid of any problems. One of the most common AC troubles is when it simply does not cool or lets out warm air. If you’re struggling with this issue and wondering why your AC is not cooling, you have come to the right place! The pros at OnTime Service are here to tell you why your AC might not be providing the cool air you need.

  1. The Thermostat is Still On “Heat”

This might seem like a silly mistake, but it is more common than you think. Make sure your thermostat is on “cool” instead of “heat.” In addition, make sure your thermostat is “Auto” instead of “Fan.” The latter setting keeps the fan on even when your AC is not going through a cooling cycle, which can use up unnecessary energy.

  1. You Have Little Refrigerant

Refrigerant, or Freon, is the cooling agent that is necessary for your AC to perform the cooling cycle. If your system is lacking in the right amount of refrigerant, it might stop providing proper cooling. Since refrigerant is in a closed-loop system, the only way it runs out is if there is a leak. Refrigerant leaks should be dealt with immediately as they can worsen your AC’s efficiency and performance, if left ignored. Since refrigerant is a dangerous compound, professional HVAC technicians are best equipped to refill the refrigerant and repair the leak.

  1. Your Air Filter is Dirty

One of the easiest ways you can maintain your air conditioner is by making sure your air filter is clean. You can ensure the cleanliness of your air filter by replacing it every month or so. A clean air filter can improve air flow and reduce your heating and cooling costs by up to 15%. A dirty air filter on the other hand can clog up and reduce proper air flow as well as your AC’s performance. So, while your AC might continue to run, it will not be providing the cooling you need. In some cases, a clogged air filter can cause your evaporator coil to freeze, further reducing your AC’s ability to perform.

  1. You Might Have an Air Leak

Air leaks can increase your energy costs, burden your air conditioner, and reduce the cooling your home gets. Make sure you replace all the weatherstripping around your doors and windows, as air leaks are the most common in those areas. However, the most dangerous air leak of all can be found in your attic. Make sure your attic is properly insulated –  consider getting an attic stair cover to further prevent air leaks.
