What is the SEER2 rating of the Tempstar T5H8T60*K*AAA?

The Tempstar T5H8T60*K*AAA is rated at up to 17.5 SEER2 and 13.0 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 85 certified matchups SEER2 ranges from 15.5-17.5.

Is the Tempstar T5H8T60*K*AAA 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 5-ton model.

How much does the Tempstar T5H8T60*K*AAA cost to run per year?

At its rated efficiency it costs about $1,494-$4,218 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,872 in Phoenix and $3,548 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 Tempstar T5H8T60*K*AAA?

ENERGY STAR lists 85 certified combinations for this outdoor unit. The highest-rated ones use FTMA5B60L0D, QFVA5D6021X, FCMA5B60L0D*+WALLCON.

A good fit if…

You want a choice of indoor units - 85 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.

Questions5

What is the SEER2 rating of the Tempstar T5H8T60*K*AAA?: The Tempstar T5H8T60*K*AAA is rated at up to 17.5 SEER2 and 13.0 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 85 certified matchups SEER2 ranges from 15.5-17.5.
Is the Tempstar T5H8T60*K*AAA 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 5-ton model.
How much does the Tempstar T5H8T60*K*AAA cost to run per year?: At its rated efficiency it costs about $1,494-$4,218 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,872 in Phoenix and $3,548 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 Tempstar T5H8T60*K*AAA?: ENERGY STAR lists 85 certified combinations for this outdoor unit. The highest-rated ones use FTMA5B60L0D, QFVA5D6021X, FCMA5B60L0D*+WALLCON.
What refrigerant does the Tempstar T5H8T60*K*AAA use?: It uses R-454B.
