What is the SEER2 rating of the AC Pro MHPC-H-012BSB?

The AC Pro MHPC-H-012BSB is rated at up to 25.5 SEER2 and 13.0 EER2 for cooling and up to 11.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 5 certified matchups SEER2 ranges from 19.5-25.5.

Is the AC Pro MHPC-H-012BSB good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,900 BTU/h at 5°F with a COP of 2.50, so it is still 2.5 times as efficient as electric resistance heat at that temperature.

How much does the AC Pro MHPC-H-012BSB cost to run per year?

At its rated efficiency it costs about $222-$670 a year in electricity in large U.S. cities, depending on climate and local rates - for example $285 in Phoenix and $568 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the AC Pro MHPC-H-012BSB the same as the MOOVAIR MSHEA12C2AN1?

Yes, as far as the certified ratings go. ENERGY STAR lists 4 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 AC Pro MHPC-H-012BSB?

ENERGY STAR lists 5 certified combinations for this outdoor unit. The highest-rated ones use AC PRO MWAL-H-012BBB, AC PRO MCON-H-012BBB, AC PRO M1CS-H-012BBB.
