There are a variety of reasons why your air conditioner may be running but not cooling your house. Here are three of the most typical reasons why your AC isn’t cooling.
If your house is getting a little hotter than usual, first check the thermostat settings. Check that the temperature is set to cool. If the thermostat is set to cool, double-check the temperature setting to ensure it hasn't been changed.
A blocked and dirty air filter will impede airflow and warm your home. In severe situations, it may potentially cause the machine to shut down completely.
A blocked or jammed condenser coil might be the reason for your air conditioner operating but not cooling you down. While it is functioning properly, the condenser fan draws air into the outside device via the condenser coil in order to collect heat energy from your home.
If basic troubleshooting doesn’t get your air conditioner cooling properly, call a professional HVAC technician for a diagnostic.
