What is the SEER2 rating of the Tempstar DLCMHBH24CAK?

The Tempstar DLCMHBH24CAK is rated at up to 22.3 SEER2 and 12.5 EER2 for cooling and up to 9.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 38 certified matchups SEER2 ranges from 21.3-22.3.

Is the Tempstar DLCMHBH24CAK good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,000 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 Tempstar DLCMHBH24CAK cost to run per year?

At its rated efficiency it costs about $508-$1,522 a year in electricity in large U.S. cities, depending on climate and local rates - for example $649 in Phoenix and $1,289 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

What refrigerant does the Tempstar DLCMHBH24CAK 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 18,000 BTU/h at 5°F.
You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 38 certified pairings.

Think twice if…

You mainly need heat - its HSPF2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.
