What is the SEER2 rating of the Blueridge BMSAH24HHC?

The Blueridge BMSAH24HHC is rated at up to 18.6 SEER2 and 12.0 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 2 certified matchups SEER2 ranges from 18.3-18.6.

Is the Blueridge BMSAH24HHC 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 2.14, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the Blueridge BMSAH24HHC cost to run per year?

At its rated efficiency it costs about $605-$1,536 a year in electricity in large U.S. cities, depending on climate and local rates - for example $735 in Phoenix and $1,275 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Blueridge BMSAH24HHC the same as the Kaden KOB-HH-UUX24HP-2AAMA?

Yes, as far as the certified ratings go. ENERGY STAR lists both 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 Blueridge BMSAH24HHC?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use BMS3AH24I, BMS2AH24I.
