Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Tempstar T5H8T60*K*AAA* at the three ENERGY STAR test temperatures (cooling capacity is 58,000 BTU/h for reference).
Retention at 17°F: 63% · at 5°F: 52%. Learn how to use these numbers in our cold-climate guide.

Frequently asked questions
How much does the Tempstar T5H8T60*K*AAA* cost to run per year?
At the U.S. average residential electricity price of 18.16¢/kWh and typical national heating and cooling hours, we estimate about $2,850 per year ($2,102 heating, $747 cooling). It ranges from about $1,615 in Louisiana to $6,521 in Maine.
Does the Tempstar T5H8T60*K*AAA* work in cold weather?
It is not ENERGY STAR cold-climate certified. It delivers 31,800 BTU/h at 5°F (52% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.
What size is the Tempstar T5H8T60*K*AAA*?
It is rated at 58,000 BTU/h of cooling, roughly 5 tons, and 61,500 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.
Is the Tempstar T5H8T60*K*AAA* the same as the Comfortmaker C5H8T60*K*AAA*?
Very likely. Both are certified by Carrier Corporation with identical capacities and efficiency ratings in the ENERGY STAR database, which indicates the same equipment sold under different brands.
