why is my HVAC system freezing up

HVAC

The answer to 'why is my HVAC system freezing up' is that there are several common causes, including low refrigerant levels, a dirty air filter, or a problem with the blower fan. When an HVAC system freezes up, it can lead to reduced airflow, poor cooling performance, and potentially more serious damage if not addressed.

Some of the most common symptoms of a freezing HVAC system include ice buildup on the coils, reduced airflow from the vents, and the system cycling on and off more frequently. This can be caused by issues like a refrigerant leak, a malfunctioning thermostat, or a problem with the blower fan not circulating air properly.
