Heating Seasonal Performance Factor (HSPF) is a heating efficiency rating for heat pumps. The higher the rating, the more efficient the heat pump. A more efficient heat pump will result in less energy use and increased energy savings over the life of the system, compared to a less efficient heat pump.

What is considered a good HSPF rating?

Generally, you should look for heat pumps with a HSPF rating of between 8 and 10. Heat pumps with a rating of at least 8.2 HSPF are awarded the ENERGY STAR® label by the U.S. EPA. However, for a heat pump to have the ENERGY STAR label, it must also have a Seasonal Energy Efficiency Ratio (SEER) rating of 12 or greater.
