An HVAC project carried out to the millimeter in a Villeray apartment: four-season comfort, neat aesthetics above a wall unit, and a compact technical layout perfectly suited to Montreal plexes.
An installation designed for real use, not just for the technical specifications
The customer context
In a semi-open kitchen in a typical Villeray–Saint-Michel–Parc-Extension home, our client wanted a system that efficiently heats in winter and cools in summer without taking up space. The room has high units under the installation area and a low ceiling with very little clearance. The expectations: silence , visual sobriety and low consumption .
The equipment chosen: Zephyr – wall-mounted range
We offer a Zephyr wall-mounted heat pump (recent residential range), ideal for living rooms: minimalist design, discreet display of the setting on the front, progressive ventilation and precise control. The available powers cover common needs (from 9,000 to 18,000 BTU for most well-insulated Montreal apartments), allowing sizing on a case-by-case basis .
Concrete benefits for the occupant
-
Stable comfort thanks to inverter modulation and uniform airflow.
-
Quiet operation, crucial in a kitchen open to the living room.
-
Energy efficiency with reduced consumption in mid-season.
-
Easy maintenance : filters accessible through the front cover, quick washing.
What we did on site: AirGreen method and finishing touches
Precise installation under ceiling
The indoor unit is installed at the top , centered above the upper cabinet. We respect the recommended clearances to ensure air intake and avoid hot recirculation. The support is laser-calibrated to ensure perfect horizontality and the slope of the drain .
Short and discreet refrigeration path
-
Right side exit through the wall, horizontal white trunking to hide connections and communication cable.
-
Controlled bending radius to preserve the integrity of the insulation and limit pressure losses.
-
Sealing of the drilling treated with silicone and air barrier foam to prevent any infiltration and thermal bridges .
-
Gravity drainage aligned with the slope of the wall: no condensate pump , therefore zero additional noise and reduced maintenance .
Finishing details that make the difference
-
Flush-fitting cladding matching the wall, clean visual above the cabinets.
-
Anti-vibration mountings to protect the partition and maintain low noise levels .
-
Communication cable management designed to facilitate future maintenance.
Controlled commissioning
-
Nitrogen pressure tests then high vacuum on the connections.
-
Check superheat/subcooling according to installed power.
-
Hot/cold tests and drain flow validation.
-
Setting up the remote control and explaining to the customer the useful modes (Auto, Heating, Air Conditioning, Dehumidification).
Sizing: the right power, in the right place
The heat balance takes into account the surface area, insulation, exposure, and neighboring cooking ducts that can disrupt air movement. In this open-kitchen-living room configuration, a 9,000 or 12,000 BTU is often suitable. Choosing "bigger" is not synonymous with better: an oversized appliance short-cycles, generates temperature surges, and unnecessarily wears out the compressor. Our AirGreen approach is to size correctly , for maximum efficiency and increased lifespan .
Daily life: HVAC usage and maintenance tips
Settings for smart comfort
-
When heating, maintain a stable setting ; the inverter automatically adjusts the power, which reduces consumption .
-
In summer, activate the Dehumidification mode on heavy days: this improves the feeling of comfort even at higher settings, which saves energy.
-
Orient the shutter so that the flow sweeps the room without blowing directly onto the table or counter.
Annual maintenance recommended
A complete HVAC maintenance (gentle cleaning of the heat exchanger, electrical inspection, and verification of refrigeration parameters) keeps the heat pump efficient. Between visits, rinse the filters every 4 to 8 weeks, depending on kitchen occupancy.
Construction site challenges and applied solutions
Reduced clearance under ceiling
The low ceiling and the presence of cabinets require precise positioning . We have reserved a free space above the facade for the breathing of the device and subsequent interventions (opening the hood, removing the filters).
High cabinet immediately below
To avoid any interaction between the airflow and the woodwork, we adjust the shutter's orientation to wide horizontal mode. This setting limits the risk of cold spots on the worktop and ensures uniform diffusion towards the dining area.
Minimalist technical path
To preserve the kitchen's aesthetics, the connection layout is deliberately short and linear. The white cable duct aligns with the wall-ceiling junction and visually disappears. This approach also reduces pressure losses and improves the appliance's responsiveness .
Grants, regional reach and compliance
Recent and efficient wall-mounted heat pumps may be eligible for provincial and utility assistance based on their performance indices. AirGreen assists with the verification of criteria and the preparation of files for projects in Montreal , Laval , Longueuil , as well as on the North Shore and the South Shore . Our teams comply with the safety , refrigeration and electrical standards applicable in Quebec, with complete traceability of interventions.
Why entrust your HVAC installation to AirGreen?

-
Careful execution : clean holes, reconstituted air barrier , discreet hood and gravity drain as soon as the configuration allows it.
-
After-sales service : maintenance, troubleshooting and parts availability.
-
Local experience : hundreds of successful installations in plexes and condos across Greater Montreal , with careful attention to detail that guarantees long-term comfort.
Express FAQ
Is a heat pump suitable for the whole house?
In multi-room homes, a single wall-mounted unit covers the main open area. For closed rooms, we offer multi-zone solutions or custom-designed add-ons.
Is it noisy?
The Zephyr wall-mounted range is distinguished by its very low noise levels . Our installation with anti-vibration mounts and a smart choice of placement ensures a quiet experience.
What maintenance should be planned?
Annual HVAC maintenance is generally sufficient. Between visits, clean the filters depending on kitchen usage and the presence of suspended grease.
Project review
In this Villeray–Saint-Michel–Parc-Extension apartment, the installation of a Zephyr wall-mounted heat pump above a wall unit combines comfort , energy efficiency and aesthetic integration . The short white chute layout , gravity drain , and rigorous commissioning ensure reliable operation, summer and winter. This is a typical example of an AirGreen HVAC installation : precise, durable and perfectly adapted to the realities of Montreal apartments.
