What is the SEER2 rating of the MDV MOX630-60HFN10-M3?

The MDV MOX630-60HFN10-M3 is rated at up to 16.2 SEER2 and 8.9 EER2 for cooling and up to 8.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 12 certified matchups SEER2 ranges from 15.2-16.2.

Is the MDV MOX630-60HFN10-M3 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,000 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.

How much does the MDV MOX630-60HFN10-M3 cost to run per year?

At its rated efficiency it costs about $1,475-$3,667 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,780 in Phoenix and $3,035 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 MDV MOX630-60HFN10-M3?

ENERGY STAR lists 12 certified combinations for this outdoor unit. The highest-rated ones use MVBM-60C28T6N10, MVBC-60HWFN10-MD3E, MVBC-60HWFN10-MD3E-D.

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.
