Why Is My AC Running but Not Cooling?

Is your air conditioner not blowing cold air but running? There are several possible reasons why an AC may be running but not cooling, including: 

  • Dirty air filter – A dirty air filter can restrict the airflow to the AC unit, causing the evaporator coils to freeze over and preventing the unit from blowing cold air. This reduction in airflow also puts added strain on the AC’s fan and compressor, potentially leading to further malfunctions and decreased efficiency.
  • Low refrigerant levels – Low refrigerant levels in an AC unit can cause the system to struggle to remove heat from the air, leading to warm air being circulated instead of cool air. This can occur due to refrigerant leaks or improper refrigerant charging during installation and can cause the AC to work harder and eventually break down if not addressed promptly.
  • A malfunctioning thermostat – A malfunctioning thermostat can prevent the AC from turning on or cause it to turn off too soon, resulting in warm air being circulated instead of cool air. Incorrect thermostat settings, such as incorrect temperature readings or programming, can lead to this issue and cause the AC not to blow cold air effectively.
  • Clogged condenser coils – Clogged condenser coils can reduce the efficiency of an AC unit by preventing it from releasing heat outside, leading to warm air being circulated instead of cool air. This issue is often caused by dirt, debris, and other buildups on the coils and can be resolved through regular cleaning and maintenance of the AC unit.
  • Malfunctioning fan – A malfunctioning fan in an AC unit can prevent proper air circulation, leading to warm air being circulated instead of cool air. This issue can be caused by various factors, such as a damaged fan motor, worn fan blades, or issues with the fan’s electrical connections, and can often be resolved through fan repair or replacement.
  • Failing compressor- A failing compressor in an AC unit can prevent the refrigerant from properly circulating, causing your AC not blowing cold air. This issue can be caused by various factors, such as electrical issues, a refrigerant leak, or mechanical failure, and can often result in complete AC system failure if not addressed promptly.

These problems can prevent the AC from cooling the air effectively or from circulating cool air throughout the house. To determine the root cause of the issue, it may be necessary to contact a professional for further inspection.

How Do I Fix My AC Not Getting Cold?

Fixing an AC unit that is not getting cold may require simple steps such as changing a dirty air filter, checking the thermostat settings, or cleaning the condenser coils. If these steps do not resolve the issue, a more in-depth inspection by a professional HVAC technician may be necessary to diagnose and repair problems with low refrigerant levels, a malfunctioning fan, or a failing compressor. To ensure that your AC is functioning properly, it is also important to schedule regular maintenance with a professional HVAC technician.

How Do You Unclog an AC Condenser Coil?

To unclog an AC condenser coil, follow these steps:

  1. Turn off the power to the AC unit.
  2. Locate the condenser unit, which is typically located outside the building.
  3. Remove any debris or obstructions from around the unit.
  4. Using a soft-bristled brush or a coil cleaning solution, clean the fins of the condenser coil.
  5. Rinse the coil with a hose to remove any debris.
  6. Reassemble the unit and turn the power back on.

It is important to handle the AC unit with care to avoid damaging the delicate fins and always to follow the manufacturer’s guidelines and safety precautions when performing maintenance on an AC unit. If you are unsure about cleaning the condenser coil yourself, it is best to contact a professional HVAC technician for assistance.
