What is the SEER2 rating of the Trane 5TWV0X24A1?

The Trane 5TWV0X24A1 is rated at up to 22.4 SEER2 and 12.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 84 certified matchups SEER2 ranges from 18.4-22.4.

Is the Trane 5TWV0X24A1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,200 BTU/h at 5°F with a COP of 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the Trane 5TWV0X24A1 cost to run per year?

At its rated efficiency it costs about $464-$1,401 a year in electricity in large U.S. cities, depending on climate and local rates - for example $594 in Phoenix and $1,187 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Trane 5TWV0X24A1 the same as the American Standard 5A6V0X24A1?

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 5TWV0X24A1?

ENERGY STAR lists 84 certified combinations for this outdoor unit. The highest-rated ones use 5PX*B006AS3, 5TXCB006AS3, 5TEMCB03AV31+TDR.

A good fit if…

You want low cooling bills - its SEER2 beats 99% of central heat pumps.
Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 18,200 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 84% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Nothing stands out - its ratings have no weak spot for its class.

Questions6

What is the SEER2 rating of the Trane 5TWV0X24A1?: The Trane 5TWV0X24A1 is rated at up to 22.4 SEER2 and 12.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 84 certified matchups SEER2 ranges from 18.4-22.4.
Is the Trane 5TWV0X24A1 good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,200 BTU/h at 5°F with a COP of 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
How much does the Trane 5TWV0X24A1 cost to run per year?: At its rated efficiency it costs about $464-$1,401 a year in electricity in large U.S. cities, depending on climate and local rates - for example $594 in Phoenix and $1,187 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the Trane 5TWV0X24A1 the same as the American Standard 5A6V0X24A1?: 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 5TWV0X24A1?: ENERGY STAR lists 84 certified combinations for this outdoor unit. The highest-rated ones use 5PX*B006AS3, 5TXCB006AS3, 5TEMCB03AV31+TDR.
What refrigerant does the Trane 5TWV0X24A1 use?: It uses R-454B.
