What is the SEER2 rating of the Trane 5TWR5030A1?

The Trane 5TWR5030A1 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 140 certified matchups SEER2 ranges from 15.2-16.0.

Is the Trane 5TWR5030A1 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 5TWR5030A1 cost to run per year?

At its rated efficiency it costs about $826-$2,038 a year in electricity in large U.S. cities, depending on climate and local rates - for example $994 in Phoenix and $1,685 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Trane 5TWR5030A1 the same as the American Standard 5A6H5030A1?

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 5TWR5030A1?

ENERGY STAR lists 140 certified combinations for this outdoor unit. The highest-rated ones use 5TXCB006AS3+TSTAT, 5PX*B006AS3+TSTAT, 5PX*B006AS3+TSTAT+P0V0B000M40SD.

A good fit if…

You want a choice of indoor units - 140 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.

Questions6

What is the SEER2 rating of the Trane 5TWR5030A1?: The Trane 5TWR5030A1 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 140 certified matchups SEER2 ranges from 15.2-16.0.
Is the Trane 5TWR5030A1 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 5TWR5030A1 cost to run per year?: At its rated efficiency it costs about $826-$2,038 a year in electricity in large U.S. cities, depending on climate and local rates - for example $994 in Phoenix and $1,685 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the Trane 5TWR5030A1 the same as the American Standard 5A6H5030A1?: 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 5TWR5030A1?: ENERGY STAR lists 140 certified combinations for this outdoor unit. The highest-rated ones use 5TXCB006AS3+TSTAT, 5PX*B006AS3+TSTAT, 5PX*B006AS3+TSTAT+P0V0B000M40SD.
What refrigerant does the Trane 5TWR5030A1 use?: It uses R-454B.
