What size heat pump for a 1 story 1150 sf house?

To determine the appropriate size heat pump for a 1,150 square foot house, you generally need about 20-30 BTUs per square foot, depending on factors like climate, insulation, and specific heating/cooling needs. This means you would likely require a heat pump with a capacity ranging from approximately 23,000 to 34,500 BTUs. It's best to consult with an HVAC professional for a precise calculation based on your home's unique characteristics.
