What is the SEER2 rating of the Heil H5H8T60*K*AAA?

The Heil H5H8T60*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 255 certified matchups SEER2 ranges from 15.5-17.5.

Is the Heil H5H8T60*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 Heil H5H8T60*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.

Is the Heil H5H8T60*K*AAA the same as the Comfortmaker C5H8T60*K*AAA?

Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

Which indoor units work with the Heil H5H8T60*K*AAA?

ENERGY STAR lists 255 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 - 255 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.

Questions6

What is the SEER2 rating of the Heil H5H8T60*K*AAA?: The Heil H5H8T60*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 255 certified matchups SEER2 ranges from 15.5-17.5.
Is the Heil H5H8T60*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 Heil H5H8T60*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.
Is the Heil H5H8T60*K*AAA the same as the Comfortmaker C5H8T60*K*AAA?: Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
Which indoor units work with the Heil H5H8T60*K*AAA?: ENERGY STAR lists 255 certified combinations for this outdoor unit. The highest-rated ones use FTMA5B60L0D, QFVA5D6021X, FCMA5B60L0D*+WALLCON.
What refrigerant does the Heil H5H8T60*K*AAA use?: It uses R-454B.
