What is the SEER2 rating of the Comfort-Aire HRG1518S1R-**A?

The Comfort-Aire HRG1518S1R-**A is rated at up to 16.8 SEER2 and 13.5 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 142 certified matchups SEER2 ranges from 15.2-16.8.

Is the Comfort-Aire HRG1518S1R-**A 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 Comfort-Aire HRG1518S1R-**A cost to run per year?

At its rated efficiency it costs about $503-$1,291 a year in electricity in large U.S. cities, depending on climate and local rates - for example $612 in Phoenix and $1,073 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 Comfort-Aire HRG1518S1R-**A?

ENERGY STAR lists 142 certified combinations for this outdoor unit. The highest-rated ones use EA(C;U)1P30A+TDR+TXV, 7EH30BX-0*+TDR, 7EC30BX-0*+TDR.

What refrigerant does the Comfort-Aire HRG1518S1R-**A 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.

A good fit if…

You want a choice of indoor units - 142 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 central heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.
Comfort and noise matter - a single-stage compressor runs only full-on or off.
