What is the SEER2 rating of the GREE GMV-V60WL/C-T(U)?

The GREE GMV-V60WL/C-T(U) is rated at up to 21.0 SEER2 and 11.0 EER2 for cooling and up to 9.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2 certified matchups SEER2 ranges from 17.0-21.0.

Is the GREE GMV-V60WL/C-T(U) good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 42,000 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the GREE GMV-V60WL/C-T(U) cost to run per year?

At its rated efficiency it costs about $1,349-$4,018 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,720 in Phoenix and $3,401 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

What refrigerant does the GREE GMV-V60WL/C-T(U) 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 42,000 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 mini-splits.
You mainly need heat - its HSPF2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.
