What is the SEER2 rating of the Kenmore PHR536000K***K1?

The Kenmore PHR536000K***K1 is rated at up to 15.5 SEER2 and 12.0 EER2 for cooling and up to 7.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Kenmore PHR536000K***K1 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 Kenmore PHR536000K***K1 cost to run per year?

At its rated efficiency it costs about $1,040-$2,971 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,308 in Phoenix and $2,502 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

What refrigerant does the Kenmore PHR536000K***K1 use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

You want a choice of indoor units - 11 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You mainly need heat - its HSPF2 is below average for packaged heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.
