Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Luxaire XH936E2C11 at the three ENERGY STAR test temperatures (cooling capacity is 35,600 BTU/h for reference).
Retention at 17°F: 90% · at 5°F: 96%. Learn how to use these numbers in our cold-climate guide.
