What is the SEER2 rating of the MOOVAIR MSHMA33C2AN1?

The MOOVAIR MSHMA33C2AN1 is rated at up to 19.5 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.

Is the MOOVAIR MSHMA33C2AN1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 35,000 BTU/h at 5°F with a COP of 1.98, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the MOOVAIR MSHMA33C2AN1 cost to run per year?

At its rated efficiency it costs about $796-$2,158 a year in electricity in large U.S. cities, depending on climate and local rates - for example $985 in Phoenix and $1,806 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the MOOVAIR MSHMA33C2AN1 the same as the CanAir 4C28SCH33H21?

Yes, as far as the certified ratings go. ENERGY STAR lists 10 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 MOOVAIR MSHMA33C2AN1?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses MWHMA33C2AS1.
