What is the SEER2 rating of the Friedrich FPHFR24A3D?

The Friedrich FPHFR24A3D is rated at up to 20.0 SEER2 and 12.0 EER2 for cooling and up to 10.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 15 certified matchups SEER2 ranges from 19.0-20.0.

Is the Friedrich FPHFR24A3D good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 24,000 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the Friedrich FPHFR24A3D cost to run per year?

At its rated efficiency it costs about $563-$1,456 a year in electricity in large U.S. cities, depending on climate and local rates - for example $687 in Phoenix and $1,211 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
