GREE CLIVIA R32 and GREE EXTRÊME R32: what changes on the certificate, what stays the same

Two GREE wall-mounted series on R‑32, at 12,000 BTU and 230 V, both sold by AirGreen and ENERGY STAR cold climate certified. Their two AHRI certificates read line by line: some values differ, others are identical, including the HSPF2 for the coldest region.

Estimated operating cost

What the electricity costs, in dollars, winter and summer

AirGreen estimate for the same 12,000 BTU/h zone in Montréal, at Hydro-Québec Rate D, taxes included. Both heat pumps are calculated exactly the same way, with the same method as on all our comparison pages; only their certified efficiencies change. Electric baseboards serve as a reference point.

Same amount in winter, a gap in summer. Both certificates give an HSPF2 of 8.0 in Region V, the value this method uses, so the estimated heating cost is the same. The difference between the two comes from cooling, where the SEER2 is 24.5 for the CLIVIA R32 and 29.5 for the EXTRÊME R32.
How this amount is calculated
  1. Heat needed over the winter. A zone whose heat loss reaches 12,000 BTU/h ( kW) at −23.1 °C, the Montréal design temperature: kW × 24 h × 4,167 degree-days ÷ (18 − (−23.1)) = kWh of heat for round-the-clock heating, all winter. Heating degree-days (base 18 °C) and design temperature: Natural Resources Canada, HOT2000 climate data, Montréal Intl station. With fewer hours a day (“Heating” slider), the heat is reduced in the same proportion, for the heat pump and for the baseboards alike: this is a simplification that ignores the recovery after a temperature setback.
  2. Electricity for heating. Heat pump: heat × 3.412 ÷ HSPF2 Region V, the AHRI certificate value published by NEEP. Region V is the coldest in the standard, and its calculation includes the electric backup expected when the heat pump is no longer enough. Electric baseboards: 1 kWh of electricity for 1 kWh of heat.
  3. Electricity for cooling. 12,000 BTU/h ÷ SEER2 × hours a day × 60 days ÷ 1,000: the method of Hydro-Québec’s air-conditioning calculator, with the SEER2 seasonal efficiency from the AHRI certificate. The number of hours is a scenario, adjustable above from 1 to 24 h. At 24 h, the calculation assumes rated capacity all day: that is a maximum, since a variable-speed unit slows down once the room is at the right temperature.
  4. Price. Hydro-Québec Rate D in effect on April 1, 2026: 7.065¢ per kWh up to 40 kWh a day, 11.142¢ beyond that; the average price, 9.104¢, is the one Hydro-Québec’s calculators use. GST and QST included. Network access charges, the same with or without a heat pump, are not counted.

AirGreen method v1.1, November 9, 2026. An estimate is meant to compare units under the same conditions. The actual bill depends on the house, insulation, settings and use; this amount is not a promise.

The staircase

From one series to the other, step by step

Each step is an AHRI certificate value that is not the same for the two units, measured under the same conditions. The step goes up when the EXTRÊME R32 value is the higher one, down when it is the CLIVIA R32 value, and its height follows the gap. What is identical is gathered on the landing, just below.

AHRI certified values published by NEEP (records 383739 and 389444), accessed November 9, 2026. Height of a step: the gap between the two values, in proportion to the CLIVIA R32 value. The steps do not add up and do not make a score. The minimum capacities and their COPs, which also differ, are in the certified data.

The landing: what does not change

The same values on both certificates, and the same in GREE’s documents for both series.

Extreme cold

Below −15 °C: two certified points, at the same temperatures

NEEP certifies both units at −15 °C, then at −30 °C, under the same conditions: 11,000 and 12,200 BTU/h maximum at −15 °C, 7,300 and 8,500 BTU/h at −30 °C. Between the two, no point is certified: the table then gives the range between the two published values, with what GREE plots in its service manuals.

Same temperature, same test. At −30 °C, NEEP lists 7,300 BTU/h for the CLIVIA R32 (COP 1.51) and 8,500 BTU/h for the EXTRÊME R32 (COP 1.75): a gap of 1,200 BTU/h, the same as at −15 °C. GREE states a heating range down to −30 °C for both series and gives no capacity figure below that.

A feature missing from a brochure is not necessarily missing from the unit: the document simply does not mention it. Names in quotation marks are GREE’s own terms, translated here from the French brochures.

Sound

How loud each one is, according to GREE

GREE Canada publishes eight sound pressure levels for each indoor unit, with no speed names: from 20 to 43 dB(A) for the CLIVIA R32, from 19 to 43 dB(A) for the EXTRÊME R32. Outdoors, one value per unit: 52 and 55 dB(A).

dB(A)

How to read these figures. dB(A) measures a noise level as the ear perceives it: the lower the figure, the quieter the unit. Each dot is a published fan level, from slowest to fastest.

Why this is not a ranking. GREE publishes neither the distance nor the measuring conditions, and the same speed rank does not necessarily match the same airflow from one series to the other.

Published value

Measurements published by GREE for each series, with no conditions stated: read them as reference points, not as a ranking.

The GREE CLIVIA R32 brochure in English, undated, prints other values for the same unit: 48, 44 and 40 dB(A) at three speeds, and 62 dB(A) outdoors. The Clivia series service manual gives 62 dB(A) as the sound power of the outdoor unit, and 52 dB(A) as its sound pressure. This page follows the dated document.

Frequently asked questions

What people ask about these two GREE wall units

What changes on the certificate between the CLIVIA R32 and the EXTRÊME R32?

Mostly cooling and the heating maximums. SEER2 goes from 24.5 to 29.5 and EER2 from 13.0 to 15.2. In heating, the Region IV HSPF2 goes from 9.5 to 10.0, and the maximum certified capacity from 11,000 to 12,200 BTU/h at −15 °C, then from 7,300 to 8,500 BTU/h at −30 °C. The rated COP at −8.3 °C goes the other way: 2.11 for the CLIVIA R32, 2.06 for the EXTRÊME R32.

Why is the estimated winter cost the same for both?

AirGreen’s estimate uses the HSPF2 for Region V, the coldest in the standard, and both certificates give the same value there: 8.0. The difference in the estimate therefore comes from cooling, where the SEER2 values differ. In a real house, maximum capacity in extreme cold also affects the share of backup heating, which this estimate does not break down.

Which one delivers more heat at −30 °C?

NEEP measures both at −30 °C, under the same conditions: 8,500 BTU/h maximum for the EXTRÊME R32 (COP 1.75) and 7,300 BTU/h for the CLIVIA R32 (COP 1.51). That is the coldest certified point for each.

The EXTRÊME R32 brochure shows a SEER2 of 28.0. Why 29.5 here?

GREE Canada brochure no. 032025 prints 28.0; AHRI certificate 215386290, published by NEEP and carried by the ENERGY STAR directory, shows 29.5. When a brochure and the certificate do not agree, this page follows the certificate. The same goes for the COP at 8.3 °C: 4.60 in the brochure, 4.53 on the certificate, and 3.81 against 3.78 for the CLIVIA R32.

Are the two indoor units the same size?

No. The CLIVIA R32 unit is 32 61/64 in wide and weighs 20.9 lb; the EXTRÊME R32 unit is 38 3/16 in wide and weighs 33.1 lb, per GREE Canada. The slider in the Installation section shows what that means on your wall.

Do these series go by other names?

Yes. The EXTRÊME R32 shares AHRI certificate 215386290 with the GREE AIRY R32: same AHRI and NEEP certified values. The CLIVIA R32 belongs to the NEEP “Clivia” series, where several names show similar values. Our pages on the Clivia and Airy platforms give the model numbers and the differences, name by name.

Are they ENERGY STAR certified?

Yes, with the cold climate designation for both, per the ENERGY STAR directory (CLIVIA R32: certified November 7, 2025; EXTRÊME R32: November 20, 2025; market listed: United States).

Are they eligible for rebates?

Eligibility depends on the official list in force on the date of purchase. This page promises no amount; the current list is checked when you get your quote.
