What is the SEER2 rating of the TOSOT TMV-V60WL/NHC-T(U)?

The TOSOT TMV-V60WL/NHC-T(U) is rated at up to 22.5 SEER2 and 10.5 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 3 certified matchups SEER2 ranges from 17.5-22.5.

Is the TOSOT TMV-V60WL/NHC-T(U) good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 46,500 BTU/h at 5°F with a COP of 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the TOSOT TMV-V60WL/NHC-T(U) cost to run per year?

At its rated efficiency it costs about $1,266-$4,222 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,677 in Phoenix and $3,616 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the TOSOT TMV-V60WL/NHC-T(U) the same as the GREE GMV-V60WL/NHC-T(U)?

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.
