What is the SEER2 rating of the Luxaire XH618E2S11?

The Luxaire XH618E2S11 is rated at up to 16.0 SEER2 and 12.5 EER2 for cooling and up to 8.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1266 certified matchups SEER2 ranges from 15.2-16.0.

Is the Luxaire XH618E2S11 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 1.5-ton model.

How much does the Luxaire XH618E2S11 cost to run per year?

At its rated efficiency it costs about $499-$1,315 a year in electricity in large U.S. cities, depending on climate and local rates - for example $613 in Phoenix and $1,097 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 Luxaire XH618E2S11?

ENERGY STAR lists 1266 certified combinations for this outdoor unit. The highest-rated ones use JHE24B5AC2SS1, CTF24B5ABS1, CTF24B5ABS1+JME12B2SN1.

A good fit if…

You want a choice of indoor units - 1,266 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.
Comfort and noise matter - a single-stage compressor runs only full-on or off.

Questions5

What is the SEER2 rating of the Luxaire XH618E2S11?: The Luxaire XH618E2S11 is rated at up to 16.0 SEER2 and 12.5 EER2 for cooling and up to 8.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1266 certified matchups SEER2 ranges from 15.2-16.0.
Is the Luxaire XH618E2S11 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 1.5-ton model.
How much does the Luxaire XH618E2S11 cost to run per year?: At its rated efficiency it costs about $499-$1,315 a year in electricity in large U.S. cities, depending on climate and local rates - for example $613 in Phoenix and $1,097 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 Luxaire XH618E2S11?: ENERGY STAR lists 1266 certified combinations for this outdoor unit. The highest-rated ones use JHE24B5AC2SS1, CTF24B5ABS1, CTF24B5ABS1+JME12B2SN1.
What refrigerant does the Luxaire XH618E2S11 use?: It uses R-454B.
