What is the SEER2 rating of the York YH536E2S11?

The York YH536E2S11 is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 304 certified matchups SEER2 ranges from 15.2-16.0.

Is the York YH536E2S11 good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 3-ton model.

How much does the York YH536E2S11 cost to run per year?

At its rated efficiency it costs about $979-$2,482 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,188 in Phoenix and $2,059 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 YH536E2S11?

ENERGY STAR lists 304 certified combinations for this outdoor unit. The highest-rated ones use CTM48C5CFS1, CTF48C5CFS1, CTU48C5XFS1+TXV.

A good fit if…

You want a choice of indoor units - 304 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
Cooling cost matters most - its SEER2 is below average for central heat pumps.
You mainly need heat - its HSPF2 is below average for central heat pumps.

Questions5

What is the SEER2 rating of the York YH536E2S11?: The York YH536E2S11 is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 304 certified matchups SEER2 ranges from 15.2-16.0.
Is the York YH536E2S11 good for cold climates?: It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 3-ton model.
How much does the York YH536E2S11 cost to run per year?: At its rated efficiency it costs about $979-$2,482 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,188 in Phoenix and $2,059 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 YH536E2S11?: ENERGY STAR lists 304 certified combinations for this outdoor unit. The highest-rated ones use CTM48C5CFS1, CTF48C5CFS1, CTU48C5XFS1+TXV.
What refrigerant does the York YH536E2S11 use?: It uses R-454B.
