The answer to 'how does inspection work' is that an HVAC inspection is a thorough examination of your home's heating, ventilation, and air conditioning system. During an inspection, a qualified HVAC technician will evaluate the various components of your system to ensure it is operating efficiently and safely.
The inspection typically includes checking the condition of the air filters, inspecting the thermostat, testing the airflow, and examining the refrigerant levels. The technician will also look for any signs of wear or damage, such as cracks, leaks, or loose connections. They may also perform a combustion analysis on gas-powered furnaces to ensure proper operation and safety.
