What is the SEER2 rating of the Comfort-Aire A-VMH28TV-1?

The Comfort-Aire A-VMH28TV-1 is rated at up to 23.0 SEER2 and 12.5 EER2 for cooling and up to 10.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 9 certified matchups SEER2 ranges from 20.0-23.0.

Is the Comfort-Aire A-VMH28TV-1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 25,000 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.

How much does the Comfort-Aire A-VMH28TV-1 cost to run per year?

At its rated efficiency it costs about $574-$1,642 a year in electricity in large U.S. cities, depending on climate and local rates - for example $722 in Phoenix and $1,383 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

What refrigerant does the Comfort-Aire A-VMH28TV-1 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.
