Energy Efficiency
HSPF
Heating Seasonal Performance Factor — a measure of your heat pump's heating efficiency over the entire heating season, where higher numbers mean more efficient heating.
What Is a HSPF?
HSPF measures heating efficiency by dividing total heating output (in BTUs) over a season by the total electricity consumed (in watt-hours). Current federal minimum is HSPF2 7.5 for heat pumps in our region. Higher-end heat pumps can achieve HSPF2 ratings of 10 or higher. Like SEER/SEER2, the HSPF2 standard was updated in 2023 to reflect more realistic testing conditions. HSPF is particularly important in Southern Oregon where heat pumps run in heating mode for much of the year.
Why It Matters for Your Home
Since heat pumps in Southern Oregon spend more time heating than cooling, the HSPF rating often matters more than the SEER rating for your total energy costs. A heat pump with a high HSPF will keep your winter electricity bills lower. When comparing heat pump options, pay close attention to both ratings to understand year-round efficiency.
