Trane heat pump

5TWR5036A1

Ducted split systemSingle-stageENERGY STAR Most Efficient (some pairings)

The Trane 5TWR5036A1 is a ducted split system heat pump outdoor unit with a rated cooling capacity of 35,200 BTU/h (about 3 tons) and a single-stage compressor running on R-454B refrigerant. ENERGY STAR lists 481 certified indoor-unit pairings for it. In cold weather it still delivers 17,800 BTU/h at 5°F — 54% of its 47°F output, below the 76% median across the 308 models we track (better than 22% of them). Its HSPF2 of 8.5 is higher than 33% of models in our database, and its best certified SEER2 of 16.5 beats 23%.

Our take in 30 seconds

Best for: mild climates or homes with backup heat

Strengths

  • Uses newer, lower-impact R-454B refrigerant
  • Also sold under 1 other badge, so you can compare more quotes for the same unit

Good to know

  • Only 54% of its heat output remains at 5°F; plan on backup heat in hard freezes
  • Single-stage compressor runs on/off at full power, so it is less smooth than inverter models

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 Trane 5TWR5036A1 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 $1,584 per year ($1,121 heating, $463 cooling). It ranges from about $944 in Louisiana to $3,519 in Maine.

Does the Trane 5TWR5036A1 work in cold weather?

It is not ENERGY STAR cold-climate certified. It delivers 17,800 BTU/h at 5°F (54% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.

What size is the Trane 5TWR5036A1?

It is rated at 35,200 BTU/h of cooling, roughly 3 tons, and 32,800 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.

Is the Trane 5TWR5036A1 the same as the American Standard 5A6H5036A1?

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.
