The answer to 'inspection freezing up' is that a frozen HVAC system is a common problem that can have several causes, including a dirty air filter, low refrigerant levels, or a problem with the defrost cycle. Symptoms include ice buildup on the coils, reduced airflow, and the system shutting off unexpectedly.
In many cases, a frozen HVAC system can be fixed with some basic troubleshooting and maintenance. However, if the problem persists or you're unsure of the cause, it's best to call a professional HVAC technician to diagnose and repair the issue. They have the expertise and tools to properly identify and fix the problem, ensuring your system is running efficiently and safely.
