GREE FLEXX R32 · GUD with E air handler · Updated Oct. 27, 2026

GREE FLEXX R32 central heat pump, E air handler. GUD outdoor units, E air handlers, four AHRI certificates: the systems Dettson documents as Flexx R32, on the market since March 2024.

4 systems, from 2 to 5 tons, on 2 GUD outdoor units. The GUD36W2 carries the 2- and 3-ton, the GUD60W2 the 4- and 5-ton; each size has its own E air handler and its own certificate. Before signing, three things get checked: the model numbers, the certificate, the printed warranty.

From market to warranty

Your E system, from its market date to its warranty.

Four steps, four public sources: ENERGY STAR, NEEP, Hydro-Québec’s list and the warranty Dettson prints. Then pick your tonnage to get the numbers to find on your quote.

March 31, 2024On the marketENERGY STAR dates the 3-ton E system from that day and the 5-ton from April 4, 2024; the 2- and 4-ton follow on Dec. 18, 2024. The 3- and 5-ton E systems are the first R-32 GREE central systems on the market among those AirGreen offers.
Sept. 16, 2026CertifiedENERGY STAR certification date of the four E systems: cold climate and Most Efficient. NEEP lists them too, status “Live”.
Your installation9 months for LogisVertHydro-Québec must receive the claim no later than nine months after installation. The list amount depends on the tonnage, capped at the pre-tax cost.

The documents

What is published for the E systems, and what is still to be confirmed at the quote stage.

Two systems that share the same outdoor unit differ by their air handler, and the air handler sets the certificate. Here is what each source says about the four E systems.

To confirm

We take the outdoor unit data from them (circuits, line set, sound) and the printed warranty. Their tables are those of the G air handlers: the full documentation of the E air handler is to be confirmed at the quote stage.

AirGreen × GREE

Four E certificates, and a quote that names them.

GREE builds the GUD outdoor unit and the E air handler. AirGreen calculates the tonnage, checks the numbers with you and installs the system.

The GREE shop

All 4 GUD + E systems, right below.

Each product sheet gives the AHRI number, the GUD outdoor unit and the E air handler. Check the letter E first.

Know before you buy

Cold and line sets for the E systems.

Two tools built from the NEEP certificates and Dettson’s table. They get you ready for the visit.

Heat from the E systems, from 8.3 °C to −30 °C.

Pick a size. At 2 tons the E system keeps 96% of its rating at −15 °C; from 3 to 5 tons, 100%. Bars: the rating, then the maximums NEEP publishes.

Why no certified figure exists at −23 °C, and what each tonnage keeps at −30 °C: the GREE central heat pumps page.

Technician’s corner

The GUD outdoor unit data per Dettson, and the E systems’ certified efficiency.

Two circuits

Outdoor unit: MCA 27.7 A and 30 A protection (2 and 3 tons), 39.9 A and 45 A (4 and 5 tons). The air handler has its own circuit: Dettson’s table gives the G air handlers’ values, and the E unit’s are read off its nameplate.

Dettson X61067C

The outdoor unit

GUD36W2: one 1/6 HP fan motor, 990 × 960 × 370 mm, 85 kg. GUD60W2: two 1/6 HP motors, 900 × 1260 × 340 mm, 109.5 kg. 60 to 63 dB(A), no measuring distance published.

Questions

What people ask us about the GUD + E systems.

FLEXX ULTRA R32 or FLEXX R32: what are these systems called?

Dettson presents them as the “Flexx R32 Series”, and its sheet says “FLEXX”. At GREE Comfort, the FLEXX ULTRA R32 name designates the FXU systems, which have their own page. What identifies yours is the numbers: GUD36W2/NHE-D(U) or GUD60W2/NHE-D(U) outdoor unit, GUD…AH2/E-D(U) air handler and one of the certificates 216621482, 214568826, 216621484 or 214568857.

What warranty does Dettson print for its Flexx R32 series?

Its submittal X60062F prints a 10-year base warranty on parts and 10 years on the compressor (labour not included), plus a 2-year extension with registration for a purchase made at Wolseley. Its sheet X61067C words the condition differently: “when product is registered and/or proof of installation”. Ask for the written version that applies to your model number.

Does the 2-ton E system lose more heat in deep cold?

A little, and only at −15 °C: NEEP rates it at 24,000 BTU/h, 96% of its 25,000 BTU/h at 8.3 °C, while the 3-, 4- and 5-ton E systems keep their full rating (34,000, 48,000 and 54,000 BTU/h). At −30 °C the gap disappears: 18,000 BTU/h maximum, like the FXU and UNIX R32 2-tons. No point is published between those two temperatures.

How do I check that my quote matches the right certificate?

Three numbers must match: the outdoor unit (GUD36W2 or GUD60W2), the air handler with the letter E, and the AHRI certificate the tool at the top of the page gives for that tonnage. The same outdoor unit with another air handler is another certificate, and sometimes another LogisVert amount.

How far can the outdoor unit be from the air handler?

Up to 30 m of line set, or 98.4 ft, and 15 m of rise, or 49.2 ft, per Dettson’s table. The first 7.5 m are pre-charged at the factory; one pair of lines at every size, 3/8 in and 3/4 in.

Can it work with my gas furnace?

Dettson presents the Flexx R32 series as dual-fuel compatible. All gas work is done by a licensed partner: our RBQ licence covers the heat pump, its refrigerant lines and its electrical connection. To keep the furnace and add a coil to it, see the FLEXX R32 add-on, GCAC coil page.
