Why Is My AC Not Cooling Below 75?

Why Is My AC Not Cooling Below 75?

If you run your air conditioner full blast but still can’t obtain a comfortable temperature, you probably wonder, “Why is my AC not cooling below 75?” At Fast Response Heating & Cooling, we know all the reasons your AC unit has trouble performing. For fast results, always find a customized solution for AC problems.

Dirty Air Filter

Your AC’s cooling power depends largely on the condition of its air filter. In addition to filtering out contaminants, the filter can restrict the system’s proper airflow. When the filter becomes too dirty, it can block the blowing air from circulating through your home.

Clean your filter at least once a month to avoid this issue.

Refrigerant Leak

Refrigerant lines provide the essential function of transporting heat outside your home, where it dissipates. The system then transports cold air back into your home. If you have a refrigerant leak, your air conditioner can’t keep your home cool.

Clogged Drain Line

One of the most overlooked AC issues is a blocked drain line. Your AC device removes moisture from the air and collects the resulting moisture in a drain pan. If the drain pan clogs, it prevents the system from functioning as intended.

Dirty Evaporator or Condenser Coils

If you’re wondering, “Why is my AC not cooling below 75?” check the device for dirty condenser coils or a frozen evaporator coil. Both coils play a pivotal role in controlling heat. You’ll find the condenser coil in the outdoor unit and the evaporator coil in the indoor portion of your AC system.

Undersized AC System

If you installed an undersized AC unit, it won’t keep you cool. A competent HVAC specialist can help you upgrade to a more appropriate model and should take time to learn your needs so they can suggest the right size. You should also use the opportunity to find the right energy star rating so you can save money in the long term on lower energy bills. Contact us today to have an expert come take a look at your AC system.

Extreme Outdoor Temperature

On abnormally hot days, your AC unit may have trouble keeping your home cool. Do you notice your air conditioner only has trouble when the outdoor air reaches a certain temperature? Ask your HVAC professional about possible solutions.

Tripping Circuits

If your AC system has trouble keeping up, you may have a power issue. The most obvious sign is frequently tripping circuits. Tripping circuits always indicate a serious problem you should resolve as quickly as possible.

Malfunctioning Thermostat

Your thermostat allows you to maintain optimal comfort, no matter what that means to you. If your air conditioner system can’t reach your set temperature, it may not indicate a problem with your AC device. Instead, have your HVAC technician check the thermostat’s calibration and see if that resolves the issue.
