Heating Seasonal Performance Factor or HSPF

Heating Seasonal Performance Factor HSPFHeat pumps efficiency is rated in HSPF or Heating Seasonal Performance Factor. As a general matter the higher the rating the more heating and cooling you get per watt of electricity so the higher the number the better.

HSPF Heating Seasonal Performance FactorThe minimum heating efficiency for heat pumps is 6.8 HSPF. Most heat pumps which were built before 1992 have HSPF ratings below 5.0. A HSPF of 7.5 or higher is considered high-efficiency. High efficiency heat pumps and air conditioners installation costs are higher initially but lower utility bills significantly. Typically a high efficiency air conditioner or heat pump pays for itself in saving in a few years.
