On a hot summer day, there’s nothing more refreshing than walking into a cool home. Unfortunately, if your air conditioning unit isn’t working correctly, you could be greeted by a whoosh of warm air. There are a few reasons this could happen. The guide below looks at the potential causes so you can seek HVAC repair.  

3 Reasons Your AC Isn’t Cooling

1. Wrong Thermostat Setting

First, ensure the thermostat is not set to “heat.” Additionally, there may be temperature days when the outdoor unit off. However, if the thermostat is on “on” instead of “auto,” the fan will continue to blow, pulling warm air without cooling it. 

2. Dirty Air Filter

HVAC air filters are designed to keep dirt and dust particles from accumulating on internal components and inhibiting operation. They also reduce the circulation of these particles within the home, improving your indoor air quality.

Generally, traditional filters should be changed every season. However, if you have pets whose hair might clog the system or if you smoke, replace them more frequently. A dirty filter not only reduces system efficiency, resulting in less cooling power but will also raise your utility bills.

3. Low Refrigerant

Air conditioning systems use refrigerant to cool warm air. If there is a leak in the line, the unit may blow hot. You may also hear strange noises or see ice on the evaporator coils. Refrigerant is highly toxic, so call an HVAC repair professional to fix the leak quickly.
