Precise comfort in a Montreal kitchen: our method for a clean, quiet and durable installation
Project context and client expectations
At AirGreen , we regularly work in Montreal plexes with compact kitchens that open onto a back patio. Here, our client wants responsive summer cooling and efficient supplemental heating in the spring and fall, without noise or direct drafts in the preparation area. We offer a recent Sharp wall-mounted heat pump with R-32 refrigerant , known for its efficiency and reduced GHG emissions. The goal: a homogeneous airflow from the kitchen area to the dining room while preserving aesthetics.
Interior installation: above the window, to the nearest millimeter
The indoor unit is positioned at the top of the wall, above the window transom and aligned with the ceiling molding. This placement allows:
-
to exploit natural stratification (hot air rises, cool air descends),
-
to clear the window and patio door opening area,
-
to stretch the air jet along the worktop without blowing directly onto the sink.
The shutters are set for automatic horizontal/vertical sweeping to avoid cold spots near the counter. Noise levels remain minimal thanks to the ear-distance and the rigid masonry wall, which limits vibrations.
Connection path: short, discreet and watertight
We favor the shortest and straightest route possible:
-
Single hole through the wall, sloping slightly outwards for gravity drainage of condensate.
-
Optimized length of refrigerant connections (approximately 1.5 to 2 m between the head and the exterior), which minimizes pressure losses and improves the COP in air conditioning as well as light heating.
-
White formwork/capping matching the moldings for a clean finish around the start of the lines, with vapor barrier tape at the critical point and closed-cell insulating foam around the drilling.
The result: a discreet, airtight layout that protects the building envelope and seasonal performance.
Condensate management: priority to gravity
In this configuration, gravity drainage is favored (constant slope towards the outside). No unnecessary condensate pump :
-
less maintenance,
-
zero risk of additional noise,
-
increased reliability.
We install a non-return valve on the exterior side and an insulated sleeve to prevent condensation on the interior finishes.
Outdoor unit: controlled ventilation, snow removal and vibrations
At the rear, the outdoor unit is installed in such a way as to ensure:
-
air intake and discharge free from any obstacle (wall clearance and lateral clearance),
-
a rigid installation plan (galvanized wall brackets or detached slab depending on the facade),
-
sufficient elevation for snow and runoff,
-
silent blocks adapted to filter structural vibrations.
This approach protects the equipment and keeps the perceived noise level in the kitchen to a minimum.
Performance and energy efficiency
The Sharp R-32 heat pump offers an excellent compromise between seasonal efficiency and compactness . For kitchen/dining room use:
-
Targeted cooling during cooking periods: the modern exchanger quickly evacuates thermal gains (oven, plates, sunlight).
-
Mid-season supplemental heating : the machine supports comfort without starting the main system, with low operating costs.
-
Optimized defrosting and inverter drive: stable cycles, controlled consumption and increased component longevity.
Acoustic comfort and air quality
For a kitchen space, we regulate:
-
Automatic speeds as a priority, then a fixed average speed during prolonged cooking sessions (limits fat recirculation).
-
Orientation of the shutters to avoid direct blowing on the sink and cutting area.
-
Maintenance reminder : Air filter should be cleaned more often than a living room filter (fine grease). We offer an HVAC maintenance schedule tailored to kitchen use.
Aesthetics and integration
The appliance fits into an environment of dark tile backsplash and white joinery:
-
the high implantation line preserves the perspective on the terrace;
-
the matching hood and moldings avoid the “added on” effect;
-
the passage of the lines is hidden and accessible for future maintenance.
Security, compliance and guarantees
Our HVAC installation complies with the manufacturers' specifications:
-
diameters and tightening torques of the fittings,
-
vacuum draw with micron meter and leak test,
-
nitrogen immersion during brazing if applicable,
-
electrical check (dedicated circuit breaker, adequate gauge, protective sheath).
We provide a commissioning report (temperatures, pressures, intensities) and explain best practices to the customer: filters, clearances, natural defrosting, and precautions in winter.
Grants and incentives
Recent high-efficiency R-32 wall-mounted heat pumps are generally eligible for assistance programs in Quebec . Depending on the exact power and efficiency of the Sharp unit chosen, the project may be eligible for energy efficiency assistance. We guide our clients in Montreal , Laval , Longueuil , North Shore and South Shore in pre-qualification and preparation of supporting documents (detailed invoices, proof of performance, compliance photos).
Tips for using a kitchen
-
Dry mode during humid heat waves: reduces perceived humidity without excessive cold.
-
Auto mode to smooth out variations during meal preparation.
-
Free air inlets : avoid leaning objects above the unit (plants, boxes).
-
Coordination with the hood : use the hood while cooking; the heat pump then stabilizes the temperature and humidity.
Preventive Maintenance: Small Cost, Big Difference
-
Cleaning the filters : every 4 to 6 weeks in intensive kitchen use.
-
Annual inspection by our technicians: clean coil, condensate tray, electrical tightening, probe and card testing.
-
Outdoor clearance : keep leaves, snow and objects away.
These actions maintain seasonal efficiency and extend the life of the compressor.

Common Mistakes We Avoid
-
Direct blowing onto the sink or cooking area: source of discomfort.
-
Tortuous connection routes : pressure losses and noise.
-
Condensate drainage without slope : risks of backflow and odors.
-
Undersizing in a sunny kitchen: short cycles, premature wear.
Our thermal load diagnosis takes into account orientation, glazing and actual use.
Result: immediate comfort, controlled operating costs
The installed Sharp wall-mounted heat pump provides precise comfort in the kitchen and distributes conditioned air to the dining area. Thanks to the short path , gravity discharge and fine adjustments , the system operates quietly, while maintaining low operating costs and a reduced carbon footprint (R-32).
Frequently Asked Questions (selection)
Is this solution suitable for a ground floor opening onto a terrace?
Yes, the short route and clear exterior installation guarantee performance and ease of maintenance.
And in winter?
The machine provides effective backup during cool periods; in very cold weather, it supports the main system and improves local comfort.
Can we add a second head later?
Depending on the configuration chosen (single or multi), we offer upgrades to a MultiZone heat pump to air condition additional rooms.
