Why Is My AC Constantly Running but Not Cooling?

 

If your AC is running but not cooling, the problem is often caused by restricted airflow, low refrigerant, dirty coils, a clogged air filter, a faulty thermostat, frozen evaporator coils, or a failing compressor. These issues force your air conditioner to run longer without effectively cooling your home, leading to higher energy bills and unnecessary wear on the system.

Before calling for service, you can:

  • Replace or clean a dirty air filter.
  • Check that your thermostat is set to Cool and the desired temperature is lower than the current room temperature.
  • Make sure vents are open and unobstructed.
  • Clear debris from around the outdoor condenser unit.

If these steps don't restore cooling, it's best to have your system inspected by an HVAC professional to prevent further damage. At Modern Comfort And Air, we provide expert diagnostics and repairs to get your air conditioner working efficiently again.
