What is the SEER2 rating of the York HH860E2S12?

The York HH860E2S12 is rated at up to 18.0 SEER2 and 11.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2201 certified matchups SEER2 ranges from 15.2-18.0.

Is the York HH860E2S12 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,000 BTU/h at 5°F with a COP of 2.32, so it is still 2.3 times as efficient as electric resistance heat at that temperature.

How much does the York HH860E2S12 cost to run per year?

At its rated efficiency it costs about $1,165-$3,298 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,461 in Phoenix and $2,775 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 York HH860E2S12?

ENERGY STAR lists 2201 certified combinations for this outdoor unit. The highest-rated ones use JHC60C5CH2SS1, JSE60D5CJ2SS1, JHC60D5CJ2SS1.

What is the SEER2 rating of the York HH860E2S12?: The York HH860E2S12 is rated at up to 18.0 SEER2 and 11.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2201 certified matchups SEER2 ranges from 15.2-18.0.
Is the York HH860E2S12 good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,000 BTU/h at 5°F with a COP of 2.32, so it is still 2.3 times as efficient as electric resistance heat at that temperature.
How much does the York HH860E2S12 cost to run per year?: At its rated efficiency it costs about $1,165-$3,298 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,461 in Phoenix and $2,775 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 York HH860E2S12?: ENERGY STAR lists 2201 certified combinations for this outdoor unit. The highest-rated ones use JHC60C5CH2SS1, JSE60D5CJ2SS1, JHC60D5CJ2SS1.
What refrigerant does the York HH860E2S12 use?: It uses R-454B.
