Installation of a Gree Console R32 (indoor system) in Rosemont–La Petite-Patrie

Seamless comfort without encroaching on the walls: our Gree interior console brings immediate and discreet fresh air to a Rosemont condo

Context and objectives of the project

In a modern apartment in Rosemont–La Petite-Patrie , we are working to improve summer and mid-season comfort without compromising the interior aesthetics. The client wants:

• a compact HVAC solution that does not monopolize wall height,

• gentle air diffusion in living areas,

• a clean, fast and easily maintained installation,

• the possibility of additional heating in autumn/winter with a compatible external compressor.

The Gree R32 indoor console perfectly meets these criteria. It fits into the bottom of the wall, like a modern radiator, while remaining connected to a mini-split outdoor compressor (single or multi-zone) to ensure efficient air conditioning and heating .

Why a Gree R32 indoor console for a Montreal condo?

• Low installation : ideal under a window or near a load-bearing wall, it frees up the upper wall strip often used for tall furniture, paintings or shelves.

• Immediate comfort : the front and top blowing distributes the air at occupancy height, limiting the layers of hot air on the ceiling.

• R-32 efficiency and refrigerant : better seasonal efficiency and reduced charge compared to R-410A.

• Silence : very low noise levels, adapted to the typical Montreal condo plateau where the rooms are open.

• Compatibility : The console can be combined with the Gree R32 ranges (single or FreeMatch R32 multi-zone 2 to 5 heads), allowing a wall head to be added later in a bedroom or office.

Study of space and technical choices

The apartment features an open-plan living room with light wood floors, white walls, and a side hallway. Our recommendations:

• Positioning : bottom of wall, central axis of the living room for uniform diffusion.

• Seat height : approx. 120–180 mm above the floor to maintain good air intake and facilitate cleaning.

• Condensate management : gravity drainage via a rear outlet to the outside, ensuring reliability and silence. A pump is not necessary here thanks to the available height difference.

• Refrigeration path : neat drilling at the rear of the console, discreet exterior cap, minimalist white interior capping for less than 0.5 m. Estimated total length of the refrigeration : 5 to 7 m up to the compressor, in accordance with Gree specifications.

• Power supply and communication : 14/4 connection between units; main power supply dedicated to the outdoor compressor on a circuit breaker compliant with the Quebec Code, with differential required depending on the configuration.

Installation process (a typical AirGreen day)

1. Protection of premises : covers, non-slip mats and tarpaulins, confined cutting areas.

2. Template and anchors : installation of the Gree template, laser level check, anchoring in the structure. Silent blocks to limit micro-vibrations.

3. Drilling : Core drill inclined outwards for drain gravity ; waterproof jacket inserted; air barrier/vapor barrier foam.

4. Routing : drawing of insulated copper lines (pre-bent), drain and communication cable; bending radii respected.

5. Brazing and vacuuming : brazing under nitrogen , deep vacuuming, leak testing, opening of valves.

6. Commissioning : checking pressures/temperatures, setting the shutters and the setpoint.

7. Finishes : matching white capping , UV exterior sealing, complete site cleaning.

8. Skills transfer : explanations of routine maintenance and best practices for use.

Measures and performance observed

When switched on in air conditioning mode, the supply air temperature reaches ≈ 15.3 °C in stabilized mode, confirming efficient heat exchange and consistent sizing for the main room. This delta with the ambient air ensures a rapid feeling, without aggressive air currents thanks to the motorized shutters .

In heating mode, the console takes advantage of its low installation: the hot air rises naturally, providing an enveloping sensation. With a high-performance R-32 compressor, the seasonal COP remains advantageous even at low temperatures.

Aesthetic and acoustic result

• Integration : The striated white facade and compact format blend in with the condo's refined style.

• Sound discretion : at Low speed, the hiss is almost inaudible; the Medium level is sufficient for a quick top-up at the end of the afternoon.

• Daily use : the remote control allows simple scenes (night/day), the dehumidification function improves comfort in heavy weather.

Recommended HVAC maintenance

• Filters : Light vacuuming every 3–4 weeks during use, washing in warm water if necessary.

• Battery : seasonal inspection; avoid greasy sprays.

• Drain : annual purge to prevent odors and overflows.

• Outdoor unit : 30–45 cm clearance, free defrosting in winter, comfortable cleaning of the fins.

• Professional maintenance : annual AirGreen visit (checking pressures, probes, tightening, thorough cleaning), guaranteeing performance and longevity.

Grants and Eligibility

Depending on the exterior combination chosen ( high-efficiency R-32 compressor and cold performance), this project may be eligible for provincial/local assistance programs for efficient heat pumps in Greater Montreal . We assist our clients in verifying the required technical data sheet (reference temperatures, HSPF/SEER/SCOP) and preparing supporting documents.

What this solution changes for a Montreal condo

• Targeted comfort without sacrificing upper walls.

• Energy savings thanks to R-32 and inverter.

• Scalability : possibility of adding wall heads in multi-zone (bedrooms/office).

• Light work : a single drilling, reduced capping , clean site in one day.

Pitfalls to avoid (AirGreen feedback)

• Height too low : risk of obstruction of the suction; respect the ground clearance.

• Winding drain path : prefer gravity ; a pump is only necessary if no slope is possible.

• Excessive refrigerated lengths : they penalize yield; aim for a direct and protected route.

• Undersizing : a console alone does not replace a central system for an entire home; think multi-zone when the surface area requires it.

• Neglected maintenance : clogged filters = loss of capacity, noise, overconsumption.
