What is the SEER2 rating of the Friedrich FPHFR36A3D?

The Friedrich FPHFR36A3D is rated at up to 19.5 SEER2 and 12.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 9 certified matchups SEER2 ranges from 18.5-19.5.

Is the Friedrich FPHFR36A3D good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 36,000 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 FPHFR36A3D cost to run per year?

At its rated efficiency it costs about $868-$2,379 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,079 in Phoenix and $1,994 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Friedrich FPHFR36A3D?

ENERGY STAR lists 9 certified combinations for this outdoor unit. The highest-rated ones use FRIEDRICH FPHSC36A3D, Rheem FPHSC36A3D, Ruud FPHSC36A3D.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 36,000 BTU/h at 5°F.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Cooling cost matters most - its SEER2 is below average for mini-splits.
You mainly need heat - its HSPF2 is below average for mini-splits.
