What is the SEER2 rating of the Trane 5HCL5036B1?

The Trane 5HCL5036B1 is rated at up to 18.5 SEER2 and 11.0 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 10 certified matchups SEER2 ranges from 16.0-18.5.

Is the Trane 5HCL5036B1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 30,200 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the Trane 5HCL5036B1 cost to run per year?

At its rated efficiency it costs about $813-$2,153 a year in electricity in large U.S. cities, depending on climate and local rates - for example $999 in Phoenix and $1,796 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 5HCL5036B1?

ENERGY STAR lists 10 certified combinations for this outdoor unit. The highest-rated ones use 5TDM5B04AC31, 5TDM5C04AC31, 5TDM5B03AC21.
