  For cooling only use a factor of 20 Btu's per square foot for a well insulated home, 25 Btu's per square foot for homes of average insulation, and 30-35 btu's per square foot for poorly insulated homes. When considering a heat pump, refer to our system size selector link for proper system sizing.
