What is the SEER2 rating of the Rheem WP15AY30AJ2N?

The Rheem WP15AY30AJ2N is rated at up to 15.2 SEER2 and 11.7 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Rheem WP15AY30AJ2N 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 2.5-ton model.

How much does the Rheem WP15AY30AJ2N cost to run per year?

At its rated efficiency it costs about $877-$2,309 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,077 in Phoenix and $1,925 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 Rheem WP15AY30AJ2N?

ENERGY STAR lists 8 certified combinations for this outdoor unit. The highest-rated ones use WH2TY3617STANN, RH2TY3617STANN, FHRNTT3617S*YTNA.

A good fit if…

You want a certified 2.5-ton central heat pump at a typical efficiency level.

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.
