What is the SEER2 rating of the Trane 5TWV0X48A1?

The Trane 5TWV0X48A1 is rated at up to 20.8 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 137 certified matchups SEER2 ranges from 19.4-20.8.

Is the Trane 5TWV0X48A1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 34,800 BTU/h at 5°F with a COP of 2.22, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the Trane 5TWV0X48A1 cost to run per year?

At its rated efficiency it costs about $1,020-$2,972 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,292 in Phoenix and $2,509 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Trane 5TWV0X48A1 the same as the American Standard 5A6V0X48A1?

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 5TWV0X48A1?

ENERGY STAR lists 137 certified combinations for this outdoor unit. The highest-rated ones use 5TXCD010AS3, 5PX*D010AS3, 5TEMCD07AV51+TDR.
