What is the SEER2 rating of the Midea MO1HE-H48B-2A?

The Midea MO1HE-H48B-2A is rated at up to 17.5 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 78 certified matchups SEER2 ranges from 15.2-17.5.

Is the Midea MO1HE-H48B-2A good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 48,000 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 Midea MO1HE-H48B-2A cost to run per year?

At its rated efficiency it costs about $1,206-$3,092 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,468 in Phoenix and $2,569 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 Midea MO1HE-H48B-2A?

ENERGY STAR lists 78 certified combinations for this outdoor unit. The highest-rated ones use MAUSE-H48B-2A, MAUSE-H60B-2A, MAAHE-H60B-CA-UC.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 48,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 70% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 78 certified pairings.

Think twice if…

Nothing stands out - its ratings have no weak spot for its class.

Questions5

What is the SEER2 rating of the Midea MO1HE-H48B-2A?: The Midea MO1HE-H48B-2A is rated at up to 17.5 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 78 certified matchups SEER2 ranges from 15.2-17.5.
Is the Midea MO1HE-H48B-2A good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 48,000 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 Midea MO1HE-H48B-2A cost to run per year?: At its rated efficiency it costs about $1,206-$3,092 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,468 in Phoenix and $2,569 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 Midea MO1HE-H48B-2A?: ENERGY STAR lists 78 certified combinations for this outdoor unit. The highest-rated ones use MAUSE-H48B-2A, MAUSE-H60B-2A, MAAHE-H60B-CA-UC.
What refrigerant does the Midea MO1HE-H48B-2A use?: It uses R-454B.
