What is the SEER2 rating of the Midea MO1BE-H48B-2A?

The Midea MO1BE-H48B-2A is rated at up to 16.7 SEER2 and 10.3 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 92 certified matchups SEER2 ranges from 15.2-16.7.

Is the Midea MO1BE-H48B-2A good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 42,000 BTU/h at 5°F with a COP of 1.85, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the Midea MO1BE-H48B-2A cost to run per year?

At its rated efficiency it costs about $1,263-$3,145 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,525 in Phoenix and $2,603 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 MO1BE-H48B-2A?

ENERGY STAR lists 92 certified combinations for this outdoor unit. The highest-rated ones use MAAHE-H60B-CA-UC, MAAHE-H60B-CA, MAUHE-H48B-2A.
