What is the SEER2 rating of the Midea MO1HE-H24B-2A?

The Midea MO1HE-H24B-2A is rated at up to 18.6 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; across its 160 certified matchups SEER2 ranges from 15.2-18.6.

Is the Midea MO1HE-H24B-2A good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 21,600 BTU/h at 5°F with a COP of 2.14, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the Midea MO1HE-H24B-2A cost to run per year?

At its rated efficiency it costs about $605-$1,526 a year in electricity in large U.S. cities, depending on climate and local rates - for example $733 in Phoenix and $1,266 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-H24B-2A?

ENERGY STAR lists 160 certified combinations for this outdoor unit. The highest-rated ones use MAUSE-H24B-2A, MAAHE-H24B-BA-UC, MAAHE-H24B-BA.

Questions5

What is the SEER2 rating of the Midea MO1HE-H24B-2A?: The Midea MO1HE-H24B-2A is rated at up to 18.6 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; across its 160 certified matchups SEER2 ranges from 15.2-18.6.
Is the Midea MO1HE-H24B-2A good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 21,600 BTU/h at 5°F with a COP of 2.14, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
How much does the Midea MO1HE-H24B-2A cost to run per year?: At its rated efficiency it costs about $605-$1,526 a year in electricity in large U.S. cities, depending on climate and local rates - for example $733 in Phoenix and $1,266 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-H24B-2A?: ENERGY STAR lists 160 certified combinations for this outdoor unit. The highest-rated ones use MAUSE-H24B-2A, MAAHE-H24B-BA-UC, MAAHE-H24B-BA.
What refrigerant does the Midea MO1HE-H24B-2A use?: It uses R-454B.
