What does a home inspector check in the HVAC system?
For heating, the inspector starts the furnace, checks the flame and venting, examines the visible heat exchanger for cracks or corrosion, and notes the unit's age. Because heat is essential in Minnesota, furnace condition and safety are a top priority.
Cooling testing depends on weather. Running an air conditioner in cold temperatures can damage the compressor, so when it is too cold the inspector notes that the AC could not be safely operated and recommends evaluation in suitable conditions.
Distribution and maintenance round out the review. The inspector looks at accessible ductwork, filters, and the thermostat, and notes service indicators. Knowing the system's age and condition helps you anticipate maintenance and eventual replacement costs.
