What is the SEER2 rating of the Midea MO1ES-H09B-2A?

The Midea MO1ES-H09B-2A is rated at up to 26.0 SEER2 and 16.2 EER2 for cooling and up to 13.9 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 6 certified matchups SEER2 ranges from 19.5-26.0.

Is the Midea MO1ES-H09B-2A good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,600 BTU/h at 5°F with a COP of 2.36, so it is still 2.4 times as efficient as electric resistance heat at that temperature.

How much does the Midea MO1ES-H09B-2A cost to run per year?

At its rated efficiency it costs about $163-$451 a year in electricity in large U.S. cities, depending on climate and local rates - for example $203 in Phoenix and $378 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Midea MO1ES-H09B-2A the same as the Blueridge BMS926YC?

Yes, as far as the certified ratings go. ENERGY STAR lists 3 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 Midea MO1ES-H09B-2A?

ENERGY STAR lists 6 certified combinations for this outdoor unit. The highest-rated ones use MIDEA MFAHU-H09B-2A, MIDEA MSEHU-H09B-2A, MIDEA MCAHU-H09B-2A.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
