What is the SEER2 rating of the MRCOOL CENTRAL-24-HP-C-230B00-O?

The MRCOOL CENTRAL-24-HP-C-230B00-O is rated at up to 18.4 SEER2 and 11.7 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 52 certified matchups SEER2 ranges from 15.8-18.4.

Is the MRCOOL CENTRAL-24-HP-C-230B00-O good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 21,600 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the MRCOOL CENTRAL-24-HP-C-230B00-O cost to run per year?

At its rated efficiency it costs about $612-$1,591 a year in electricity in large U.S. cities, depending on climate and local rates - for example $748 in Phoenix and $1,324 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 MRCOOL CENTRAL-24-HP-C-230B00-O?

ENERGY STAR lists 52 certified combinations for this outdoor unit. The highest-rated ones use MVP-24-HP-MUAH-230A00-O, MCMP1824BOTB, **AECMPT24B2AA.
