What is the SEER2 rating of the Trane 4TWV0X48A1?

The Trane 4TWV0X48A1 is rated at up to 20.0 SEER2 and 12.0 EER2 for cooling and up to 8.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 118 certified matchups SEER2 ranges from 19.0-20.0.

Is the Trane 4TWV0X48A1 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 4-ton model.

How much does the Trane 4TWV0X48A1 cost to run per year?

At its rated efficiency it costs about $1,083-$3,019 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,352 in Phoenix and $2,535 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Trane 4TWV0X48A1 the same as the American Standard 4A6V0X48A1?

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 4TWV0X48A1?

ENERGY STAR lists 118 certified combinations for this outdoor unit. The highest-rated ones use TEM8B0C60V51+TDR, 4TXCD010DS3+P0V0D000M50SC+RP, 4PX*DU60BS3+P0V0D000M50SC+RP.

What refrigerant does the Trane 4TWV0X48A1 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.

4-ton central heat pump · XV20I

Trane 4TWV0X48A1

Excellent cooling efficiency and average heating efficiency for a 4-ton central heat pump, but not rated for cold climates.

Ranks #15 of 319 4 ton central heat pumps for cooling efficiency, and costs about $1,251 a year to run in a mixed climate like Atlanta.

SEER2: 20.0 Cooling efficiency over a season
Excellent · beats 94%
HSPF2: 8.7 Heating efficiency over a season
Average · beats 47%
EER2: 12.0 Cooling efficiency on a 95°F day
Average · beats 64%
Heat at 5°F: 28,600 BTU/h66% of its 47°F output
Below average · beats 20%

A good fit if…

You want low cooling bills - its SEER2 beats 94% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 118 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions6

What is the SEER2 rating of the Trane 4TWV0X48A1?: The Trane 4TWV0X48A1 is rated at up to 20.0 SEER2 and 12.0 EER2 for cooling and up to 8.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 118 certified matchups SEER2 ranges from 19.0-20.0.
Is the Trane 4TWV0X48A1 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 4-ton model.
How much does the Trane 4TWV0X48A1 cost to run per year?: At its rated efficiency it costs about $1,083-$3,019 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,352 in Phoenix and $2,535 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the Trane 4TWV0X48A1 the same as the American Standard 4A6V0X48A1?: 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 4TWV0X48A1?: ENERGY STAR lists 118 certified combinations for this outdoor unit. The highest-rated ones use TEM8B0C60V51+TDR, 4TXCD010DS3+P0V0D000M50SC+RP, 4PX*DU60BS3+P0V0D000M50SC+RP.
What refrigerant does the Trane 4TWV0X48A1 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.
