Four-season comfort, precisely placed in a Montreal apartment
At AirGreen , we have just completed the HVAC installation of a Gree Clivia R32 wall-mounted heat pump in a typical Villeray–Saint-Michel–Parc-Extension apartment. The owner wanted to stabilize the temperature of the main rooms throughout the year, reduce his electricity bill and maintain a clean aesthetic in an interior with light walls and relatively high ceilings. Our recommendation was the Gree Clivia R32 , a new generation wall-mounted head that is compact, quiet and adapted to the climatic realities of Greater Montreal.
What we achieved, step by step
Measurement and sizing. We begin each project with a precise survey: volumes to be treated, necessary airflows, window orientation, air infiltration, wall and ceiling insulation. In this home, the living area is open, with a side corridor that promotes air circulation towards the bedroom; a sizing of 12,000 to 15,000 BTU for the main head proved optimal.
Interior head placement. The Gree Clivia R32 head was installed at the top of the wall, near a corner, above a wall-mounted light fixture. This position offers three advantages:
-
better stratification for heating in winter (blowing directed towards the ground),
-
effective horizontal sweep to cool the living area in summer,
-
very short connection path to the outside, limiting losses and cycle time.
Through-hole and routing. A single, small-diameter hole was made behind the right-hand casing of the unit to pass the refrigerant lines, condensate drain and communication cable . The route was designed to be as direct as possible : approximately 35–50 cm of wall penetration, then a short external descent towards the compressor, under white capping to ensure a clean and durable finish.
Condensate management. The site's layout allows for gravity drainage ; no pump is required, which reduces maintenance and eliminates any additional noise. The slope was checked with a bubble to prevent any backflow.
Brazing, vacuuming and testing. After assembly, our technicians proceeded to:
-
a deep vacuum to remove moisture and non-condensables,
-
a leak and pressure test ,
-
commissioning with reading of parameters (inlet/outlet temperatures, compressor intensity, delta T),
-
the calibration of sweep and fan speeds for this room geometry.
Why the Gree Clivia R32 fits so well in Villeray
Design and silence. The interior module features clean lines that blend into a neutral decor. The airflow is even thanks to the motorized shutters and the fine-pitch fan. At low speed, the noise level is barely perceptible , ideal for an open-plan living room.
Next-generation efficiency and refrigerant. The Clivia R32 range uses R-32 refrigerant , which is more efficient and has a lower GWP than R-410A, promoting high efficiency in air conditioning and heating. Inverter motors adjust power according to actual demand, which limits on/off cycles and reduces consumption .
Cold weather performance. Designed for the Quebec climate, the Clivia R32 maintains stable heating during moderate to severe cold. Combined with a well-sealed enclosure, it ensures consistent comfort in high-traffic areas and adjacent rooms.
Filtration and maintenance. The washable filters are accessible without tools. We provided the client with a simplified HVAC maintenance schedule : monthly dusting during periods of heavy use, and thorough cleaning of the coils and fan by our teams depending on usage (usually annually).
Key technical details of this installation
-
Machine type: single-zone wall-mounted heat pump (mini-split).
-
Line routes: short and direct, short total length limiting pressure losses.
-
Interior finish: discreet white capping , perfectly aligned with the unit; no visible bleeding.
-
Condensate drainage: gravity , controlled slope.
-
Power supply: dedicated circuit from the panel; circuit breaker compliant with the intensity required by the chosen power.
-
External support: brackets adapted to the cladding, with anti-vibration silent blocks and sufficient ground clearance for snow.
-
Functional tests: reading of delta T in cold and hot conditions, checking of sweeping and speeds , test of simulated cold defrosting .
Results: immediate comfort, bill under control
Upon commissioning, the customer noted:
-
a rapid drop in indoor temperature during the following summer day,
-
even blowing without aggressive air currents thanks to the adjustment of the shutters,
-
heating stability on a cooler night, without annoying temperature variations.
Thanks to the correct sizing and the short path , the compressor works in its optimal efficiency zone , which results in measured consumption and contained external noise for the neighborhood.

AirGreen best practices and advice
-
Choosing an interior location: aim for a clear wall, at a good height, to allow a wide sweep and avoid obstacles (thick curtains, columns).
-
Drainage: favor gravity as soon as the configuration allows it; the pump is only used as a last resort.
-
Line lengths: keep it as short as possible , limit sharp bends, insulate well to avoid droplets in summer.
-
Annual maintenance: Professional cleaning of the coils and turbine fan maintains efficiency and air quality.
-
Winter: Clear the outdoor unit of snow and check that air is circulating freely around the condenser.
