The answer to 'how long will inspection last' is that a typical HVAC inspection will take 30-60 minutes to complete. During this time, the HVAC technician will thoroughly inspect all components of your heating and cooling system, including the thermostat, air filters, ducts, refrigerant levels, and other critical parts. They will also test the system's operation to ensure it is running efficiently and safely.
The length of the inspection can vary depending on the size and complexity of your HVAC system, as well as any specific issues or concerns that need to be addressed. In some cases, the technician may need to spend more time troubleshooting or performing additional tests to diagnose a problem. However, a comprehensive HVAC inspection should generally take less than an hour to complete.
