What Size Heat Pump Do I Need?

When it’s time 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 house, will not only impact your comfort, but can result in a shortened life of your heat pump, and leave you stuck with higher energy bills each month.

How can you be certain you know the right heat pump size for your home? Start with a load calculation from the professionals at Ambient Air. A load calculation takes specifics from your home into consideration and gauges the Btu (a number that indicates the capacity of a heat pump) needed to heat your home. The most common and broadly 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 considered during this process. Typically, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home throughout the cold winter months. It also heavily impacts 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 specific 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 should have a heat pump that can sustain the conditions of your climate every year, without overworking itself or needing back up heat.

Don’t settle for ‘close enough’ when picking your new heat pump. Let the experts at Ambient Air help you find a system that will fit your home properly.
