Heat pump sizing depends on multiple factors including your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. There’s no simple formula based on square footage alone.
A proper load calculation considers heat loss in winter and heat gain in summer, factoring in your home’s specific characteristics. This calculation determines both the heating and cooling capacity needed to maintain comfortable temperatures efficiently.
Oversized systems cost more upfront, cycle on and off frequently, and don’t control humidity well. Undersized systems run constantly and struggle to maintain comfortable temperatures. Getting the size right is critical for comfort, efficiency, and system longevity.
