Comfort designed for an open living space, installed cleanly and quickly
At AirGreen , we recently installed a Gree wall-mounted heat pump from the Clivia R32 family on a ground floor in Boucherville. The indoor unit is positioned above the dining area, facing the living room-kitchen area, to optimize air distribution throughout the space. The client's goal was clear: quiet, efficient heating and air conditioning with a low visual footprint, while keeping energy bills under control year-round.
Why orient this project towards a Gree R32
-
R-32 refrigerant : better volumetric efficiency and reduced carbon footprint compared to R-410A.
-
High seasonal efficiency : excellent air conditioning and heating performance for the inter-seasons, with stable comfort even during rapid temperature fluctuations on the South Shore .
-
Reliability and availability of parts in Quebec, a plus for HVAC maintenance and the durability of the installation.
-
Discreet design : sleek white casing blends naturally into a light wall and contemporary design.
Our step-by-step HVAC installation process
Load measurement and capacity selection
We systematically carry out a simplified load calculation (surface area, ceiling height, orientation, windows, infiltration). For a comparable open-plan living room-kitchen (approximately 35–45 m²), the relevant range is generally between 12,000 and 18,000 BTU/h . The configuration of this well-insulated home with recent windows allowed us to choose 12,000 BTU/h to ensure an excellent comfort/consumption compromise and limit short cycles.
Inner head implantation: airflow and silence
-
Height : Install at approx. 2.1–2.2 m to free up the airflow under the ceiling and avoid immediate recirculation.
-
Clearances : Lateral distances maintained to facilitate filter maintenance and sensor access.
-
Blowing : directed towards the central passageway to circulate the living area and reach the lounge area without unpleasant drafts.
-
Noise level : “Low/Quiet” mode is suitable for evening use in an open kitchen.
Clean drilling and wall crossing
The head is placed on a peripheral wall : we made a slightly sloping hole towards the outside for a gravity drain of the condensate (the most reliable and silent solution). The refrigeration connections (insulated copper), the communication cable and the drain are grouped together and exit in a layer, then capped on the outside (white UV capping) for a clean and durable finish.
Refrigeration connections and vacuum packaging
-
Controlled bending to meet minimum radii and maintain performance.
-
Brazing/flaring according to Gree recommendations; tightening to torque.
-
Vacuum draw to a stable level, then leak test (hold test) before releasing the fluid.
-
Configuration and commissioning : verification of blown temperatures, intensities and operating pressures.
Secure power supply
The outdoor unit (facade side) is connected to a dedicated circuit with a compliant circuit breaker and external disconnection . The path has been planned for the shortest possible route, limiting losses and visual impact.
Integration details that make the difference
Condensate treatment
The wall configuration allowed for gravity flow —zero pumps, meaning zero additional noise and less maintenance. We protected the outlet with a drip-stop spout to prevent any marks on the siding.
Neat finishes
-
External trunking matching the facade, stainless steel screws.
-
Condenser support (not visible here) sized for wind and frost loads; ground clearance respected for snow.
-
Sealing of the crossings with polyurethane sealant for a durable barrier to air and water.
Indoor air circulation
The head, centered on the main wall, benefits from an unobstructed environment (no tall cabinets or nearby light fixtures). The shutters can sweep horizontally across the open area and vertically direct the jet under the ceiling to extend the reach without direct air currents on the counter area.
Results achieved for the client
-
Uniform comfort in the open area thanks to automatic sweeping.
-
Quiet at low speed, perfect for meals and teleworking.
-
Contained consumption : sizing adjusted to real needs, avoiding the oversizing common in open areas.
-
Aesthetics : discreet integration into the decor; no visible interior chute.
Recommended HVAC Maintenance Best Practices
-
Filters : monthly rinse in summer and at the start of the heating season; replacement/inspection according to use.
-
Heat exchanger : professional cleaning recommended every 12 to 24 months (depends on occupancy and pets).
-
Outdoor unit : keep the perimeter free (snow, leaves); gently wash the condenser in spring.
-
Operation in extreme cold : The R32 series performs well; in case of prolonged extreme cold, adopt a stable setpoint rather than marked variations to maximize the COP.
Eligibility for programs and budget advice
High-efficiency R-32 wall-mounted heat pumps are generally included in Quebec's assistance programs when performance criteria are met. We assist our customers in Montreal , Laval and Longueuil , as well as on the North Shore and South Shore , to verify eligibility and gather supporting documents (technical sheet, proof of installation, photos). Our quotes clearly distinguish between equipment, installation and options (condensate pump, special supports, snow protection, etc.).
Pitfalls to avoid when planning a wall-mounted heat pump project
-
Oversize “to be safe”: this degrades comfort (short cycles) and can increase consumption.
-
Neglecting the drain : imposing a pump when gravity is possible increases noise and maintenance.
-
Installing too close to a corner : poor air intake, stratification.
-
Ignore the facade : a poorly cleared condenser (snow, wind corridors) harms performance and longevity.
-
Save on vacuuming : an expeditious procedure compromises the oil and the reliability of the compressor.

Express Fair
Can the head heat the whole house?
In a well-open and insulated bungalow, a wall-mounted heat pump provides excellent coverage for the living area. Closed rooms benefit from additional heat or a second head, depending on the configuration.
Do you need a condensate pump?
We reserve it for complex routes. Here, the gravity drain was possible, more reliable and quieter.
How long does it take to install?
For a standard wall configuration with straight drilling towards the outside, installation is generally completed in one day , including testing.
