What is the SEER2 rating of the Trane 5TWX6030A1?

The Trane 5TWX6030A1 is rated at up to 16.0 SEER2 and 12.0 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 139 certified matchups SEER2 ranges from 15.2-16.0.

Is the Trane 5TWX6030A1 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 2.5-ton model.

How much does the Trane 5TWX6030A1 cost to run per year?

At its rated efficiency it costs about $837-$2,057 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,007 in Phoenix and $1,699 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Trane 5TWX6030A1?

ENERGY STAR lists 139 certified combinations for this outdoor unit. The highest-rated ones use 5PX*C007AS3+TSTAT, 5TXCC007AS3+TSTAT, 5TAMXD05AV41+TSTAT.

2.5-ton central heat pump · 16 Single-Stage Heat Pump with WeatherGuard Top

Trane 5TWX6030A1

Below average cooling and heating efficiency for a 2.5-ton central heat pump, but not rated for cold climates.

Ranks #148 of 199 2.5 ton central heat pumps for cooling efficiency, and costs about $878 a year to run in a mixed climate like Atlanta.

A good fit if…

You want a choice of indoor units - 139 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
Cooling cost matters most - its SEER2 is below average for central heat pumps.
You mainly need heat - its HSPF2 is below average for central heat pumps.
Comfort and noise matter - a single-stage compressor runs only full-on or off.

Questions5

What is the SEER2 rating of the Trane 5TWX6030A1?: The Trane 5TWX6030A1 is rated at up to 16.0 SEER2 and 12.0 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 139 certified matchups SEER2 ranges from 15.2-16.0.
Is the Trane 5TWX6030A1 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 2.5-ton model.
How much does the Trane 5TWX6030A1 cost to run per year?: At its rated efficiency it costs about $837-$2,057 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,007 in Phoenix and $1,699 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Which indoor units work with the Trane 5TWX6030A1?: ENERGY STAR lists 139 certified combinations for this outdoor unit. The highest-rated ones use 5PX*C007AS3+TSTAT, 5TXCC007AS3+TSTAT, 5TAMXD05AV41+TSTAT.
What refrigerant does the Trane 5TWX6030A1 use?: It uses R-454B.
