What is the SEER2 rating of the TCL THH60HAI2NAF2U23?

The TCL THH60HAI2NAF2U23 is rated at up to 15.2 SEER2 and 9.5 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the TCL THH60HAI2NAF2U23 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 38,000 BTU/h at 5°F with a COP of 1.84, so it is still 1.8 times as efficient as electric resistance heat at that temperature.

How much does the TCL THH60HAI2NAF2U23 cost to run per year?

At its rated efficiency it costs about $1,466-$3,597 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,773 in Phoenix and $2,967 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 TCL THH60HAI2NAF2U23?

ENERGY STAR lists 6 certified combinations for this outdoor unit. The highest-rated ones use 4TXCD010DS3, 4TXCC009DS3, THH48IAI2NAF2H23.

What refrigerant does the TCL THH60HAI2NAF2U23 use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 38,000 BTU/h at 5°F.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

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.
You want the newest refrigerant - it uses R-410A, which is being phased down.
