The answer to 'how long will inspection last' is that a typical HVAC inspection will take 1-2 hours to complete. The inspector will thoroughly examine your heating, ventilation, and air conditioning system to ensure it is functioning properly and identify any potential issues. This includes checking the thermostat, air filters, refrigerant levels, ductwork, and other key components.
The exact duration of the inspection can vary depending on the size and complexity of your HVAC system, as well as any specific concerns or problems that need to be addressed. In some cases, the inspection may take longer if the technician needs to perform additional testing or diagnostics. It's always a good idea to schedule the inspection at a time when you can be present to ask questions and get a full understanding of the findings.
