Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the ACiQ B5H0V60*K*AAA* at the three ENERGY STAR test temperatures (cooling capacity is 58,000 BTU/h for reference).
Retention at 17°F: 88% · at 5°F: 71%. Learn how to use these numbers in our cold-climate guide.
