What is the SEER2 rating of the Rheem RD17AZ24AJ3N?

The Rheem RD17AZ24AJ3N is rated at up to 18.0 SEER2 and 11.2 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 92 certified matchups SEER2 ranges from 17.0-18.0.

Is the Rheem RD17AZ24AJ3N good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 17,100 BTU/h at 5°F with a COP of 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the Rheem RD17AZ24AJ3N cost to run per year?

At its rated efficiency it costs about $590-$1,592 a year in electricity in large U.S. cities, depending on climate and local rates - for example $730 in Phoenix and $1,332 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 RD17AZ24AJ3N?

ENERGY STAR lists 92 certified combinations for this outdoor unit. The highest-rated ones use TCFZ2417MTANM, RCFZ2417MTANM.

What refrigerant does the Rheem RD17AZ24AJ3N 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.

2-ton central heat pump · F Series

Rheem RD17AZ24AJ3N

Average cooling efficiency and very good heating efficiency for a 2-ton central heat pump, and certified for cold climates.

Ranks #164 of 331 2 ton central heat pumps for cooling efficiency, and costs about $665 a year to run in a mixed climate like Atlanta.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 17,100 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 70% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 92 certified pairings.

Think twice if…

You want the newest refrigerant - it uses R-410A, which is being phased down.
