** HSPF, or Heating Seasonal Performance Factor, measures the heating efficiency of your heat pump. A higher HSPF rating means greater energy efficiency, more savings and is better for the environment.

*** Annual Fuel Utilization Efficiency (AFUE) measures how efficient the appliance is in converting its fuel’s energy into heat over the course of a year.
