What is the SEER2 rating of the Trane 5HCL5024A1?

The Trane 5HCL5024A1 is rated at up to 17.0 SEER2 and 11.7 EER2 for cooling and up to 9.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Trane 5HCL5024A1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 20,000 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the Trane 5HCL5024A1 cost to run per year?

At its rated efficiency it costs about $635-$1,658 a year in electricity in large U.S. cities, depending on climate and local rates - for example $777 in Phoenix and $1,381 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Trane 5HCL5024A1 the same as the Jetson HP-24ODU-001?

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 5HCL5024A1?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated one uses 5TEM5B03AC21.
