What is the SEER2 rating of the GREE GUD60W2/NXF-D(U)?

The GREE GUD60W2/NXF-D(U) is rated at up to 19.0 SEER2 and 11.5 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 4 certified matchups SEER2 ranges from 16.0-19.0.

Is the GREE GUD60W2/NXF-D(U) good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 48,000 BTU/h at 5°F with a COP of 1.85, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the GREE GUD60W2/NXF-D(U) cost to run per year?

At its rated efficiency it costs about $1,288-$3,561 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,604 in Phoenix and $2,988 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the GREE GUD60W2/NXF-D(U) the same as the Continental WSEHV4860BA1-C?

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 GREE GUD60W2/NXF-D(U)?

ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use GUD48AH2/F-D(U), GUD60AH2/F-D(U), GCAC48H/NXA.

4-ton central heat pump · F Series

GREE GUD60W2/NXF-D(U)

A good fit if…

You want low cooling bills - its SEER2 beats 85% of central heat pumps.
Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 48,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 70% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Nothing stands out - its ratings have no weak spot for its class.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
