Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the American Standard 4A6V7X36A1 at the three ENERGY STAR test temperatures (cooling capacity is 35,600 BTU/h for reference).
Retention at 17°F: 74% · at 5°F: 58%. 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.

Frequently asked questions
How much does the American Standard 4A6V7X36A1 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 $1,649 per year ($1,231 heating, $418 cooling). It ranges from about $921 in Louisiana to $3,805 in Maine.
Does the American Standard 4A6V7X36A1 work in cold weather?
It is not ENERGY STAR cold-climate certified. It delivers 21,000 BTU/h at 5°F (58% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.
What size is the American Standard 4A6V7X36A1?
It is rated at 35,600 BTU/h of cooling, roughly 3 tons, and 36,000 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.
Is the American Standard 4A6V7X36A1 the same as the Trane 4TWV7X36A1?
Very likely. Both are certified by Trane and American Standard Heating and Air Conditioning with identical capacities and efficiency ratings in the ENERGY STAR database, which indicates the same equipment sold under different brands.
