What is the SEER2 rating of the Elios ESHMB36R2AN1?

The Elios ESHMB36R2AN1 is rated at up to 17.4 SEER2 and 11.7 EER2 for cooling and up to 10.3 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 5 certified matchups SEER2 ranges from 15.8-17.4.

Is the Elios ESHMB36R2AN1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 39,000 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 Elios ESHMB36R2AN1 cost to run per year?

At its rated efficiency it costs about $969-$2,382 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,166 in Phoenix and $1,968 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Elios ESHMB36R2AN1 the same as the KERR A-KXP36SA-1?

Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

Which indoor units work with the Elios ESHMB36R2AN1?

ENERGY STAR lists 5 certified combinations for this outdoor unit. The highest-rated ones use EAHMA36R4AS1, GCHMA36RBAS1, GCHMA36RCAS1.
