Precise comfort in a Montreal condo, without compromising on aesthetics
At AirGreen , we design each HVAC installation as an engineering project applied to everyday life. In this condo located in Villeray–Saint-Michel–Parc-Extension , we installed a Gree Clivia R32 wall-mounted heat pump to provide reliable heating in the winter and gentle cooling in the summer, with discreet integration near a patio door. The goal: performance, silence, and visual sobriety, without encroaching on the living space.
Why the Clivia R32 range?
Gree 's Clivia R32 series combines inverter technology with a new generation R-32 refrigerant, with a lower global warming potential, while ensuring high performance in cold weather. It meets three common expectations of co-owners in Greater Montreal:
-
Superior energy efficiency to reduce electricity bill;
-
4-season comfort with fine power modulation;
-
Quiet and compact design that fits into living spaces.
Context and constraints of the site
The housing has a typical urban layout: large glass opening, short wall corner, direct access to a terrace where the condenser is installed. These parameters require precise planning of passages and clearances.
Choosing an interior location
We positioned the wall head high and in a corner , a few centimeters from the ceiling, so as to:
-
Maximize air stratification and diffusion to the open area;
-
Free up the main walls for furniture;
-
Facilitate a short route of connections to the outside (crossing the side wall near the patio door).
Route and finishing of the connections
-
Estimated length of refrigeration connections: approximately 1 to 1.5 m, limiting pressure losses.
-
Discreet white capping , laid vertically then horizontally to join the drilling; fixings at regular center distance for a durable finish.
-
Gravity condensate drain with continuous slope (~2%), avoiding a pump and therefore additional noise/maintenance.
-
Crossing made with sheath and vapor barrier to preserve the building's watertightness.
Installation of the outdoor condenser
Visible from the patio door, the outdoor unit is mounted on wall brackets with anti-vibration pads . This anchor:
-
clears the ground and preserves the flow of defrost water;
-
ensures proper rear and side clearance ;
-
reduces the risks associated with frequent snow accumulation in Montreal .
Sizing and expected performance
We always size the heat pump based on the room's usage, orientation, and building envelope. Here, a 12,000 BTU configuration proved optimal for the main living area, with:
-
Competitive SEER/SEER2 and HSPF/HSPF2 for R-32 appliances;
-
useful heating capacity in negative temperatures, suitable for Greater Montreal winters;
-
intelligent defrosting limiting cycles and improving thermal stability.
Expected result: a significant reduction in costs versus electric baseboards and a low interior noise level , ideal for teleworking and condo living.
AirGreen methodology: rigor and cleanliness
Our signature is clean, verifiable and sustainable execution.
Key technical steps
-
Site protection , tracing and verification of center distances.
-
Drilling to the correct diameter , installation of an insulated sleeve and watertight sealing.
-
Installation of insulated copper lines , bending radii respected.
-
Nitrogen brazing or flared fittings to range specification, with torque controls.
-
Nitrogen pressure test (high stage) and deep vacuum (≈ 500 microns ).
-
Fluid release, leak check and functional measurements (intensity, supply/return temperatures, ΔT).
-
Finishing: capping , caulking, repainting if required, instructions for use and maintenance.
Electrical management
-
Dedicated condenser circuit according to the nameplate;
-
Compliant circuit breaker and properly sheathed communication cable between units;
-
Installation of an external disconnect switch within easy reach for maintenance.
Daily comfort: what occupants feel
-
Rapid temperature rise in the off-season then gentle modulation.
-
In summer, laminar airflow directed along the ceiling to avoid direct currents on the sofa/dining table.
-
Silent night mode and dimmable display on the front.
-
Effective dehumidification during the humid waves of July-August in Montreal , Laval and Longueuil .
Aesthetics and integration
The Clivia R32 features a smooth white facade that blends into the light colors of the living room. The short passage to the outside allows for a minimalist cable channel , without an oversized box. On the terrace side, the brackets leave space for movement and avoid traces of corrosion on the floor.
Recommended maintenance (prevention > repair)
Light but regular HVAC maintenance extends the lifespan of:
-
Filters : gentle vacuuming every 1 to 2 months; washing with warm water if necessary.
-
Internal battery : periodic professional cleaning to maintain thermal exchange.
-
Outdoor unit : leaf/snow clearance (at least 30–60 cm on each side).
-
Annual inspection by our technicians for pressure and electronic checks.
Grants and Compliance
High-efficiency R-32 wall-mounted heat pumps are generally eligible for assistance programs in Quebec. We support our customers in Greater Montreal—including the North Shore and South Shore —in gathering the required technical documents (performance sheet, certification number, proof of installation) and optimizing the application .
AirGreen Tips for Condominiums and Plexes
-
Favor a gravity drain when the configuration allows it; reliability is superior.
-
Provide a wall support with buffers if the terrace is small or subject to snow.
-
Respect clearances to maintain optimal seasonal performance and limit noise.
-
Request a refrigeration charge check and documented vacuum draw upon commissioning.
-
Consider a second head if natural air distribution does not cover one wing of the dwelling.
