Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Trane 5TWR7024A1 at the three ENERGY STAR test temperatures (cooling capacity is 24,000 BTU/h for reference).
Retention at 17°F: 71% · at 5°F: 79%. Learn how to use these numbers in our cold-climate guide.

Same equipment sold under other brands
These listings share the same certifying manufacturer (Trane and American Standard Heating and Air Conditioning) and identical certified capacities and efficiency ratings, so they are almost certainly the same hardware with a different badge. If you get quotes for any of them, you are comparing installation price and warranty, not equipment. How rebadging works.
