What Size Heat Pump Do I Need?

When you discover you need to replace your heat pump, it’s important to know that one size does not fit all. A system that is not sized appropriately for your home, will not only impact your comfort, but can result in a shortened life of your heat pump, and increase your monthly energy bills.

How can you be certain you know the correct heat pump size for your home? Your should begin with a load calculation from the professionals at Ambient Air. A load calculation takes specifics from your home into account and gauges the Btu (a number that indicates the capacity of a heat pump) necessary to heat your home. The most common and widely accepted method is a calculation of the total heat loss and heat gain of the structure using ACCA Manual J.

Some Things that Influence Heat Pump Size

  • Square Footage—How large is the home your heat pump will be required to heat? A professional will be sure to carefully measure the square footage of your house. Not every inch of your home needs to be accounted for during this process. Typically, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation supports keeping warm air from leaving your home during the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the professionals with Ambient Air examine the insulation in your walls and attic. They’ll help you find the best heat pump for your house.
  • Type of Window— Just like your walls, the particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Evaluate the range of weather you experience in Tucson. You’ll want a heat pump that can sustain the conditions of your climate every year, without overworking itself or needing back up heat.
