HSPF is a measure of efficiency for heat pumps. Heating Season Performance Factor is a ratio of the amount of heating produced to the amount of energy used defined during the heating season. Heat pumps also cool the air in a home and seasonally the efficiency of the heat pump is measured the same as an air conditioner. SEER Seasonal Energy Efficiency Ratio is the measure of energy consumed to the amount of cooling produced during a cooling season. HSPF's are commonly 8.2 to 8.5 and can be < 7.8 and > 10.0. SEER's will commonly range 13 - 16 and are commonly lower than 13 in older equipment. The minimum cooling effiency rating as of January 23, 2006 is 13 SEER. Seer ratings are now approaching 21 SEER. Ratings for are conditioners and heat pumps are connected to the system. The system includes the furnace/air handler based on the blower installed as well as the ducting and the condenser (heat pump or air canditioner) its matching coil and length (and its exposure) of the line set.RonsHVAC (talk) 03:23, 26 January 2009 (UTC)ronshvac
External links modified
[edit]Hello fellow Wikipedians,
I have just modified one external link on HSPF. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
- Added tag to https://cmcoolingcontrol.co.uk/
- Added archive https://web.archive.org/web/20111006181247/http://www.cwlp.com/energy_services/efficiency_ratings/appliance_efficiency_ratings.htm to http://www.cwlp.com/energy_services/efficiency_ratings/appliance_efficiency_ratings.htm
When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

SEER and HSPF specifications (and their wikipedia pages) should include information on where they're actually accurate.
[edit]Both SEER and HSPF attempt to quantify efficiency, which varies based on temperature, based on annual energy usage in "some location". But that location is never specified! Where in the US do the relative temperature weightings used for SEER and HSPF match the *actual* temperature profile? And more importantly, why is there no automatic calculator that calculates the SEER and HSPF at *my* location, based on the temperature profile at this location, which is what I really need to know to make a purchasing decision? — Preceding unsigned comment added by Metamerman (talk • contribs) 18:17, 2 September 2020 (UTC)
