What is the SEER2 rating of the GREE WLUD48W2/NHG-D(U)?

The GREE WLUD48W2/NHG-D(U) is rated at up to 20.0 SEER2 and 11.7 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the GREE WLUD48W2/NHG-D(U) good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 4-ton model.

How much does the GREE WLUD48W2/NHG-D(U) cost to run per year?

At its rated efficiency it costs about $1,130-$3,158 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,412 in Phoenix and $2,653 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the GREE WLUD48W2/NHG-D(U) the same as the Kinghome KD48UXO?

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 WLUD48W2/NHG-D(U)?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses WLUD48AH2/G-D(U).

4-ton central heat pump · G Series

GREE WLUD48W2/NHG-D(U)

Excellent cooling efficiency and very good heating efficiency for a 4-ton central heat pump, but not rated for cold climates.

Ranks #13 of 319 4 ton central heat pumps for cooling efficiency, and costs about $1,308 a year to run in a mixed climate like Atlanta.

SEER2: 20.0 Cooling efficiency over a season
Excellent · beats 94%
HSPF2: 9.5 Heating efficiency over a season
Very good · beats 70%
EER2: 11.7 Cooling efficiency on a 95°F day
Average · beats 43%
Heat at 5°F: 36,000 BTU/h75% of its 47°F output
Very good · beats 71%

A good fit if…

You want low cooling bills - its SEER2 beats 94% of central heat pumps.
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…

You often see nights below 0°F - it is not cold-climate certified.

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.
