Questions5
What is the SEER2 rating of the MDV MOX630-48HFN10-M3?
The MDV MOX630-48HFN10-M3 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 43 certified matchups SEER2 ranges from 15.2-16.7.
Is the MDV MOX630-48HFN10-M3 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 MDV MOX630-48HFN10-M3 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 MDV MOX630-48HFN10-M3?
ENERGY STAR lists 43 certified combinations for this outdoor unit. The highest-rated ones use MVBM-60C28T6N10, MVBC-48HWFN10-MD3E, MVBC-48HWFN10-MD3E-D.
What refrigerant does the MDV MOX630-48HFN10-M3 use?
It uses R-454B.

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.
