What is the SEER2 rating of the Trane 4TWV7X36A1?

The Trane 4TWV7X36A1 is rated at up to 17.1 SEER2 and 12.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 144 certified matchups SEER2 ranges from 17.0-17.1.

Is the Trane 4TWV7X36A1 good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 3-ton model.

How much does the Trane 4TWV7X36A1 cost to run per year?

At its rated efficiency it costs about $965-$2,406 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,165 in Phoenix and $1,992 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Trane 4TWV7X36A1 the same as the American Standard 4A6V7X36A1?

Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

Which indoor units work with the Trane 4TWV7X36A1?

ENERGY STAR lists 144 certified combinations for this outdoor unit. The highest-rated ones use TAMXB0B30V31, TAMXB0C36V31, 4TXCB006DS3.

What refrigerant does the Trane 4TWV7X36A1 use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

A good fit if…

You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 144 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You mainly need heat - its HSPF2 is below average for central heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions6

What is the SEER2 rating of the Trane 4TWV7X36A1?: The Trane 4TWV7X36A1 is rated at up to 17.1 SEER2 and 12.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 144 certified matchups SEER2 ranges from 17.0-17.1.
Is the Trane 4TWV7X36A1 good for cold climates?: It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 3-ton model.
How much does the Trane 4TWV7X36A1 cost to run per year?: At its rated efficiency it costs about $965-$2,406 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,165 in Phoenix and $1,992 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the Trane 4TWV7X36A1 the same as the American Standard 4A6V7X36A1?: Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
Which indoor units work with the Trane 4TWV7X36A1?: ENERGY STAR lists 144 certified combinations for this outdoor unit. The highest-rated ones use TAMXB0B30V31, TAMXB0C36V31, 4TXCB006DS3.
What refrigerant does the Trane 4TWV7X36A1 use?: It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.
