Common Reasons Your Air Conditioner Isn’t Cooling Properly

AC tips in Lincoln, NE

Updated: May 20th, 2024

Your air conditioning is protected against sweltering summer temperatures that can potentially lead to serious problems, such as heat stroke. However, if your AC is running continuously but not cooling your home, this warrants a call from an HVAC technician. There are several reasons why your air conditioning system will not cool your home despite running.

Clogged Air Filter

Air filters protect the AC against dirt, pollen, dust, and pollutants that can contaminate indoor air. However, when air filters become clogged, airflow is restricted, thus reducing the efficiency of the air conditioner and causing it to stop cooling. HVAC experts recommend you change your air filter quarterly and even more often if you have pets or many people living in your home.

Faulty Thermostat

Another reason your air conditioning system is failing to do its job is that the thermostat is not properly regulating the temperature inside the home. Improper temperature regulation occurs when your thermostat becomes faulty. If you have double-checked your thermostat to confirm it is set correctly but are still experiencing problems, call an HVAC technician to have your thermostat repaired or replaced.

Damaged Heat Pump

The heat pump absorbs heat from the air indoors and releases it outside. If the heat pump suffers damage, it won’t be able to transfer the heat, and this will result in warm air continuing to circulate. Some signs of a damaged heat pump include strange noises from the outdoor unit, leaks, or ice buildup. If you notice any of these signs, contact an HVAC professional to see if your heat pump is the culprit.

Dirty Outdoor Unit

The outdoor unit, also known as the condenser, releases the heat your AC removes from your home. If the condenser is covered in debris, such as dirt, leaves, or grass, it can’t release heat. As a result, your AC will continue to run but won’t be able to cool your home effectively. If you notice your outdoor unit is dirty, have a technician clear away all debris and test its functionality.
