The answer to 'inspection freezing up' is that a frozen HVAC system is often caused by a lack of airflow. This can be due to a dirty air filter, a blocked outdoor unit, or issues with the blower fan. Symptoms include ice buildup on the coils, reduced heating/cooling performance, and the system shutting off.
In many cases, homeowners can address a frozen system by replacing the air filter and clearing any debris around the outdoor unit. However, if the issue persists or you suspect a more complex problem, it's best to call an HVAC professional. They can properly diagnose the root cause and make the necessary repairs to get your system running smoothly again.
