What is the SEER2 rating of the York HH836E2S11?

The York HH836E2S11 is rated at up to 19.0 SEER2 and 11.0 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 5243 certified matchups SEER2 ranges from 15.2-19.0.

Is the York HH836E2S11 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 27,200 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the York HH836E2S11 cost to run per year?

At its rated efficiency it costs about $834-$2,127 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,014 in Phoenix and $1,766 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 HH836E2S11?

ENERGY STAR lists 5243 certified combinations for this outdoor unit. The highest-rated ones use CTF48C5CFS1, CTU48C5XFS1+TXV, CTM48C5CFS1.

Questions5

What is the SEER2 rating of the York HH836E2S11?: The York HH836E2S11 is rated at up to 19.0 SEER2 and 11.0 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 5243 certified matchups SEER2 ranges from 15.2-19.0.
Is the York HH836E2S11 good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 27,200 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
How much does the York HH836E2S11 cost to run per year?: At its rated efficiency it costs about $834-$2,127 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,014 in Phoenix and $1,766 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 HH836E2S11?: ENERGY STAR lists 5243 certified combinations for this outdoor unit. The highest-rated ones use CTF48C5CFS1, CTU48C5XFS1+TXV, CTM48C5CFS1.
What refrigerant does the York HH836E2S11 use?: It uses R-454B.
