Installation of a Gree Livo R32 wall-mounted heat pump in Griffintown (Le Sud-Ouest)

Carefully integrated into a condo with anthracite walls, designed for quiet comfort and aesthetics.

Project context: compact space, high demands

In Griffintown, condos often combine rational volumes , meticulous finishes and co-ownership constraints . Our client wanted a four-season heating and cooling solution that respected the interior aesthetics—deep gray painted walls, suspended lighting—and the building's rules regarding condenser positioning, noise level and condensate drainage. We recommended a Gree Livo R32 wall-mounted heat pump (recent range), known for its cooling performance in the summer and its efficient heating at low temperatures .

Feasibility study and choice of equipment

Why a wall-mounted heat pump in this context?

  • Flexible installation in a high corner of a room, ideal for promoting stratification and air diffusion.

  • Low indoor noise level : perfect for an office or bedroom used daily.

  • Higher energy efficiency in wall-mounted air conditioning mode in summer, and advantageous COP in heating mode.

  • R-32 refrigerant , with a lower GWP than R-410A, compatible with current Quebec market requirements .

Why the Gree Livo R32 range

  • Outstanding seasonal efficiency (SEER/SEER2 and HSPF/HSPF2 competitive for the category).

  • Smart defrosting limits unnecessary cycles in cold weather.

  • Reliable electronics and inverter components ensure fine modulation, therefore less jolts, more comfort and lower operating costs .

  • Discreet design : white hood with simple lines, blending well with the anthracite walls of the project.

Installation process: clean, fast, compliant

Interior layout

The wall head is placed at the highest point of the wall , under the ceiling, centered in relation to the volume to be treated. This positioning:

  • Optimizes the return of hot air in winter and the mixing effect in summer;

  • Avoids conflicts with pendant lighting and decorative frame installed on the neighboring wall;

  • Reduces the sound signature perceived at ear height.

The main drilling (65 mm) is made with a gravity slope towards the outside for the evacuation of condensates . The insulation of the connections is continuous up to the wall, sheathed with a vapor barrier tape to prevent surface condensation on cold walls.

Refrigerant connections and power supply

  • Estimated total length of lines: 8 to 10 meters , adapted to the size of the condo and the route to the balcony.

  • Silver-brazed deoxidized copper , deep vacuum <500 microns, vacuum maintained and nitrogen leak tested .

  • Communication and power cabling in the same external trunking, with separation at entry points for electrical safety.

  • Dedicated circuit breaker according to the outdoor unit nameplate; anti-UV cable for the outdoor portion.

Finishing and architectural integration

  • Exterior capping in anthracite (matching the dark facade) from the drilling to the condenser.

  • Foam sealing + mastic at the drilling for air/water sealing and vapor barrier .

  • Condensate management by natural slope to the outdoor unit tray, without pump (less noise, less maintenance).

Condenser on balcony: stability and silence

  • Installation on anti-vibration slab with shock-absorbing pads to limit the transmission of vibrations to the structure.

  • Regulatory distance to guardrails and neighboring walls for optimal air flow and future maintenance.

  • Accessible service line for pressure gauges and maintenance; valves protected by cover.

Quality of execution: our AirGreen method

Controls and tests

  1. Brazing under nitrogen to avoid internal oxidation.

  2. Pressure test (dry nitrogen) then vacuum controlled with a micron meter.

  3. Soft start : check for superheat and subcooling ; control of currents .

  4. Comfort measurements : air speed at 1 m, blowing temperature , noise level at 1 m and 3 m.

Cleanliness and safety of the construction site

  • Protection of painted walls (anthracite) and lighting during drilling.

  • Dust management and site restoration.

  • Documentation provided to the customer: maintenance guide, remote control programming and seasonal use advice.

Result: precise comfort, preserved aesthetics

Immediate benefits

  • Rapid temperature reduction in wall-mounted air conditioner mode; uniform sensation thanks to vertical/horizontal oscillation.

  • Stable heating in mid-season and mild winters, reducing the load on baseboards or electrical backups.

  • Perceptible silence : Inverter modulation keeps the unit at low speed once the setpoint is reached.

Sustainable benefits

  • Energy savings linked to modulation and R-32 (excellent volumetric efficiency).

  • Simplified maintenance : easy access to the filter, exchanger and connections.

  • Real estate added value : modern, clean HVAC solution, compliant with co-ownership rules .

Good practices and pitfalls to avoid (feedback)

  • Always check the building's rules regarding noise levels and condensate drainage.

  • Avoid condensate rising by pump when gravity slope is possible: it is more reliable and quieter .

  • Take care of aesthetics : choose capping to match the facade, route as short and straight as possible.

  • Anticipate maintenance : clearance around the condenser and sufficient height to evacuate snow if the balcony is open to the wind.

  • Entrust commissioning to a certified team: vacuum drawing and leak tests determine the compressor's lifespan .

AirGreen Recommended HVAC Maintenance

  • Quarterly cleaning of internal filters (gentle vacuuming + washing if reusable).

  • Annual inspection : coils, condensate tray, ventilation pallet , tightening of connections, checking of insulation on the suction line.

  • Snow removal from the balcony/condenser in winter; maintaining clearances .

  • Pre-cooling season disinfection (prevent odors and biofilms).

  • Remote control message monitoring and eco setpoint settings: 24–25°C in summer, 20–21°C in winter for comfort/savings balance .

Frequently asked questions we address in the field

“Is this eligible for financial assistance?”

Depending on the specific efficiency of the unit and current provincial programs , certain wall-mounted heat pump configurations may be eligible . We evaluate each application taking into account the housing , power (BTU), low-temperature performance and administrative requirements .

“What capacity (BTU) should I choose?”

We size based on the surface area , the envelope (windows, insulation), the room's purpose and the usage profile . In Griffintown condos, 9,000 to 12,000 BTU is often appropriate for an open living room ; beyond that, we will favor multi-zone or a second diffusion point .
