HSPF stands for Heating Seasonal Performance Factor and measures the efficiency of a heat pump over the fall and winter seasons. HSPF2 is an updated version of HSPF set by the Department of Energy (DOE) that goes into effect Jan. 1, 2023. The DOE created HSPF2 after refining HVAC system testing procedures to more closely mimic real world conditions.

Starting Jan. 1, 2023, the Department of Energy will require all split system heat pumps to have an HSPF2 rating of 7.5 or higher, and all single-packaged heat pumps to have an HSPF2 of 6.7 or higher. The best HSPF2 rating for your heat pump depends on a number of different factors, like home size and climate, so be sure to talk to your American Standard Customer Care Dealer™ before investing in a system.

How much can a higher HSPF2 save you?

A higher HSPF2 typically goes along with having a higher SEER2 and an overall more effective system. A smoothly working system can save you time and the stress of dealing with a malfunctioning heat pump, but it can also save you money.

Buying a higher-rated heat pump may cost you more initially than a lower-rated alternative. But, you could justify spending more with the potential money you save on energy bills.
