What is the SEER2 rating of the MDV MOD30-24HFN10-M1X?

The MDV MOD30-24HFN10-M1X is rated at up to 22.3 SEER2 and 12.5 EER2 for cooling and up to 13.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 11 certified matchups SEER2 ranges from 18.7-22.3.

Is the MDV MOD30-24HFN10-M1X good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 24,200 BTU/h at 5°F with a COP of 2.34, so it is still 2.3 times as efficient as electric resistance heat at that temperature.

How much does the MDV MOD30-24HFN10-M1X cost to run per year?

At its rated efficiency it costs about $492-$1,236 a year in electricity in large U.S. cities, depending on climate and local rates - for example $595 in Phoenix and $1,024 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 MOD30-24HFN10-M1X?

ENERGY STAR lists 11 certified combinations for this outdoor unit. The highest-rated ones use MSAG11D-23HRFN10-M1, MSEPD-24HRFN10-M1, MSEPD-24HRFN10-M1-D.
