Low Refrigerant Levels

If your AC is losing refrigerant, that means it’s not running at optimal efficiency. It can cause the system to shut down due to a lack of pressure, and if left unchecked, it can lead to compressor failure. Have a professional inspect your AC for leaks and repair any damage immediately.

Faulty Thermostat

If your thermostat isn’t registering the correct temperature or turning on when it should, you may have a faulty thermostat. This can cause your AC to randomly shut off because it’s unable to sense the temperature in your home.

Electrical Issues

Faulty wiring or tripped breakers can cause your AC to shut down suddenly and unexpectedly. Check your electrical panel for tripped breakers, and ensure all of your AC’s electrical connections are secure.

Dirty Evaporator Coils

The evaporator coils in your AC system absorb heat from the air. Over time, they can become covered in dirt and debris, reducing their effectiveness and causing your AC to shut down. If your AC turns off frequently, check the evaporator coils for dirt and debris and clean them if necessary.

Frozen Coils

If your AC’s evaporator coils freeze over, it can cause the system to shut down. Several things, including low refrigerant levels, dirty air filters, or a malfunctioning fan motor, can cause this. If you suspect your evaporator coils are frozen, turn off your AC and contact Holy City Heating and Air, LLC, for repairs.

Malfunctioning Compressor

The compressor in your AC system is responsible for pressuring the refrigerant, allowing it to absorb heat and cool the air. If the compressor is malfunctioning, it can cause your AC to shut down unexpectedly.

If your AC keeps shutting down randomly, it’s essential to address the issue immediately to prevent further damage to your system.
