Questions
- What is the SEER2 rating of the York HH836E2S12?
- The York HH836E2S12 is rated at up to 18.0 SEER2 and 11.7 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 3565 certified matchups SEER2 ranges from 16.0-18.0.
- Is the York HH836E2S12 good for cold climates?
- Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 28,200 BTU/h at 5°F with a COP of 2.38, so it is still 2.4 times as efficient as electric resistance heat at that temperature.
- How much does the York HH836E2S12 cost to run per year?
- At its rated efficiency it costs about $863-$2,424 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,080 in Phoenix and $2,037 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 HH836E2S12?
- ENERGY STAR lists 3565 certified combinations for this outdoor unit. The highest-rated ones use JHC36C5CD2SS1, JHC42C5CF2SS1, CTF36C5CDS2.
