What is the SEER2 rating of the Blueridge BMY24HH22C?

The Blueridge BMY24HH22C is rated at up to 21.5 SEER2 and 13.0 EER2 for cooling and up to 11.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 5 certified matchups SEER2 ranges from 18.4-21.5.

Is the Blueridge BMY24HH22C good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 27,000 BTU/h at 5°F with a COP of 2.21, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the Blueridge BMY24HH22C cost to run per year?

At its rated efficiency it costs about $524-$1,389 a year in electricity in large U.S. cities, depending on climate and local rates - for example $645 in Phoenix and $1,159 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 Blueridge BMY24HH22C?

ENERGY STAR lists 5 certified combinations for this outdoor unit. The highest-rated ones use BLUERIDGE BMY24HH22WM, BLUERIDGE BM24MFCC, BLUERIDGE BM24MCD.

What refrigerant does the Blueridge BMY24HH22C use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 27,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 82% of mini-splits.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Cooling cost matters most - its SEER2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.
