What is the SEER2 rating of the KERR A-KXP36TA-1?

The KERR A-KXP36TA-1 is rated at up to 15.8 SEER2 and 10.7 EER2 for cooling and up to 9.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the KERR A-KXP36TA-1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 36,000 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the KERR A-KXP36TA-1 cost to run per year?

At its rated efficiency it costs about $1,066-$2,613 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,282 in Phoenix and $2,157 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 KERR A-KXP36TA-1?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use KXP30/36B1A, KXP30/36C1A.
