The answer to 'how does inspection work' is that a professional HVAC technician will perform a thorough inspection of your home's heating, ventilation, and air conditioning system. This involves checking all the major components, including the furnace, air conditioner, ductwork, and thermostat, to ensure they are functioning properly and efficiently.
The inspection typically includes a visual check for any signs of damage or wear, as well as testing the system's performance and measuring key metrics like airflow, refrigerant levels, and energy usage. The technician will also clean the system and make any necessary adjustments or minor repairs to improve its operation.
