What is the SEER2 rating of the Sure SP15AZ60AJ2N?

The Sure SP15AZ60AJ2N is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 7 certified matchups SEER2 ranges from 15.2-16.0.

Is the Sure SP15AZ60AJ2N good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 34,400 BTU/h at 5°F with a COP of 2.60, so it is still 2.6 times as efficient as electric resistance heat at that temperature.

How much does the Sure SP15AZ60AJ2N cost to run per year?

At its rated efficiency it costs about $1,674-$4,451 a year in electricity in large U.S. cities, depending on climate and local rates - for example $2,060 in Phoenix and $3,716 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 Sure SP15AZ60AJ2N?

ENERGY STAR lists 7 certified combinations for this outdoor unit. The highest-rated ones use SH2CZ6024STANN, TCFZ6024STANM, SH2VZ6024STANN.

What refrigerant does the Sure SP15AZ60AJ2N 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…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 34,400 BTU/h at 5°F.

Think twice if…

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