Answer: Should I Replace My Heat Pump with the Same Size?
Not necessarily — your existing heat pump may be the wrong size for your home. Older heat pumps were often oversized, and newer high-efficiency models or improvements to your home's insulation may allow a smaller, more efficient unit. A proper heat pump replacement should include a Manual J load calculation to determine the correct size for your home as it is today, not as it was when the original unit was installed. Factors like added attic insulation, new windows, air sealing, and changes in occupancy affect the heating and cooling load. An oversized heat pump short-cycles, wastes energy, and fails to dehumidify properly. An undersized unit runs constantly and may not maintain comfort during extreme weather.
