What is the SEER2 rating of the Heil H5H3V48*K*AAA?

The Heil H5H3V48*K*AAA is rated at up to 23.0 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 539 certified matchups SEER2 ranges from 19.5-23.0.

Is the Heil H5H3V48*K*AAA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 38,500 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the Heil H5H3V48*K*AAA cost to run per year?

At its rated efficiency it costs about $929-$3,078 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,227 in Phoenix and $2,635 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 H5H3V48*K*AAA?: The Heil H5H3V48*K*AAA is rated at up to 23.0 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 539 certified matchups SEER2 ranges from 19.5-23.0.
Is the Heil H5H3V48*K*AAA good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 38,500 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
How much does the Heil H5H3V48*K*AAA cost to run per year?: At its rated efficiency it costs about $929-$3,078 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,227 in Phoenix and $2,635 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 H5H3V48*K*AAA?: ENERGY STAR lists 539 certified combinations for this outdoor unit. The highest-rated ones use FCMA5B60L0D*+WALLCON, FCMA5B48L0C*+WALLCON, EA*5X61M21A*+WALLCON.
What refrigerant does the Heil H5H3V48*K*AAA use?: It uses R-454B.
