Your selection of a ton heat pump will have a $ energy cost savings per heat pump over an estimated 15 year life expectancy compared to the base model.


  • "Base model" has an efficiency that just meets the national minimum standard for that capacity.
  • Lifetime energy cost is the sum of the discounted value of the annual energy costs based on assumed commercial heat pump life of 15 years.
  • Future electricity price trends and a discount rate of 3.2% are based on Federal guidelines.
  • $0.06 for electricity is the Federal average price in the U.S.

This cost calculator is a screening tool that estimates a product's lifetime energy cost savings at various efficiency levels. Maintenance and installation costs do not vary significantly among the same product having different efficiencies; so, these costs are not included in this calculator tool. For a detailed life-cycle cost analysis, FEMP has developed a tool called Building Life-Cycle Cost (BLCC). This downloadable tool allows the user to vary interest rates, installation costs, maintenance costs, salvage values, and life expectancy for a product or an entire energy project.
