What is the SEER2 rating of the Friedrich FPHSR12A1B?

The Friedrich FPHSR12A1B is rated at up to 22.0 SEER2 and 12.3 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Friedrich FPHSR12A1B good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 9,200 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the Friedrich FPHSR12A1B cost to run per year?

At its rated efficiency it costs about $258-$776 a year in electricity in large U.S. cities, depending on climate and local rates - for example $330 in Phoenix and $658 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Friedrich FPHSR12A1B the same as the Hisense AS-12UW1TXE00?

Yes, as far as the certified ratings go. ENERGY STAR lists 6 model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

Which indoor units work with the Friedrich FPHSR12A1B?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses FRIEDRICH FAHSW12A1C.
