Heat pumps extract heat from outside air (air-source) or ground (ground-source) and transfer it inside during winter; the process reverses for summer cooling. Heat pumps are more efficient than traditional furnaces, particularly for heating in moderate climates. Very cold climates may require supplemental heat. Air-source heat pumps are more common than ground-source due to lower cost. Inspectors assess system type, age, condition, and refrigerant levels. Proper maintenance ensures longevity.
Pro Tip
Heat pumps offer excellent efficiency for both heating and cooling. Consider upgrading to one.
Example
A home in North Carolina replaced an aging air conditioner with an air-source heat pump, providing both heating and cooling. The system cost $5,500 but eliminated the need for a separate furnace and provided 30% better heating efficiency than the original system.
