What is the SEER2 rating of the Heil H5H3V36*K*AAA?

The Heil H5H3V36*K*AAA is rated at up to 22.5 SEER2 and 12.5 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2256 certified matchups SEER2 ranges from 18.0-22.5.

Is the Heil H5H3V36*K*AAA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 29,600 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 Heil H5H3V36*K*AAA cost to run per year?

At its rated efficiency it costs about $726-$2,389 a year in electricity in large U.S. cities, depending on climate and local rates - for example $957 in Phoenix and $2,044 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Questions5

What is the SEER2 rating of the Heil H5H3V36*K*AAA?: The Heil H5H3V36*K*AAA is rated at up to 22.5 SEER2 and 12.5 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2256 certified matchups SEER2 ranges from 18.0-22.5.
Is the Heil H5H3V36*K*AAA good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 29,600 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 Heil H5H3V36*K*AAA cost to run per year?: At its rated efficiency it costs about $726-$2,389 a year in electricity in large U.S. cities, depending on climate and local rates - for example $957 in Phoenix and $2,044 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 Heil H5H3V36*K*AAA?: ENERGY STAR lists 2256 certified combinations for this outdoor unit. The highest-rated ones use EVD5X61M24A*+WALLCON, EVM5X61M24A*+WALLCON, FCMA5B60L0D*+WALLCON.
What refrigerant does the Heil H5H3V36*K*AAA use?: It uses R-454B.
