Winter comfort and summer freshness in a Montreal condo, with a clean, discreet installation optimized for air circulation
Why this project matters
In Rosemont–La Petite-Patrie, brick condominiums and compact kitchens require agile HVAC solutions. Our mission: to install a Fujitsu wall-mounted heat pump that heats efficiently in extreme cold, cools silently in summer, and integrates seamlessly above a bay window.
Site profile and technical choices
-
Context : Urban condo with large window overlooking the backyard. Standard ceiling height, wall-mounted furniture nearby.
-
Interior installation : Fujitsu wall-mounted head centered above the window for even distribution, away from hot air returns and cooking steam.
-
Condensate management : gravity drainage with continuous slope (≈2%) and single drilling on the rear facade to avoid any internal pump.
-
Refrigeration connections : ultra-short path through the wall (direct feed-through), reducing pressure losses and maximizing efficiency .
-
Noise pollution : positioning limiting reverberation on the glazing; shutter adjusted to direct air towards the living space without blowing on the occupants.
Result: a compact HVAC installation , invisible from the room, and a minimal perceived noise level thanks to the well-directed laminar flow.
The value of an “above window” positioning
Controlled air distribution
-
The laminar jet follows the ceiling and then descends, which stabilizes the temperature in the living room-kitchen area.
-
The placement avoids curtains and blinds, limiting the risks of air short circuits and coil frosting in cooling mode.
Simplified maintenance
-
Clearances respected for opening the hood and accessing the filters.
-
Pre-filtration and filter backwashing in minutes—a key benefit for seasonal HVAC maintenance .
Fujitsu Inner Head Specifications
-
Extreme cold heating mode : Inverter compressor sized for Montreal winters.
-
Intelligent defrosting : short cycles, limiting perceived power drops.
-
Silence : “Quiet” speed useful in the evening in open spaces.
-
Remote control : weekly programming to adapt instructions to living schedules.
(The exact model is not communicated by the supplier; the unit belongs to Fujitsu's high-performance wall-mounted family. We systematically size the power—9k, 12k, 18k, etc.—based on the actual heat losses of the home.)
Installation details that make the difference
Drilling and sealing
-
Core drilling at an outward angle to ensure natural condensate flow.
-
Vapor barrier and peripheral mastication to maintain the wall's watertightness and prevent any infiltration of cold air.
Exterior path (courtyard side)
-
White capping to match the woodwork to protect insulation and copper.
-
Exit height designed to stay out of the snow drift zone in winter.
-
Provision of a snow shield if necessary if the condenser is on an adjacent slab.
Food and communication
-
Multi-core communication cable between indoor unit and condenser; electrical protections on the panel in accordance with local requirements.
-
Grounding and torque-measured tightening of terminals, insulation test before commissioning.
Commissioning: the AirGreen signature
-
Deep vacuum draw until stabilization < 500 microns.
-
Leak test and refrigerant charge compensation if the length differs from the factory charge.
-
Functional checks : overheating/subcooling, intensity, supply/room temperature differential.
-
Customer education : shutter settings, Auto/Heat modes, HVAC maintenance reminder and seasonal best practices.
Urban condo operating tips
-
In winter : favor a stable setpoint (e.g. 21°C). Avoid large amplitudes to reduce defrost cycles.
-
In summer : use the auto speed, shutter half-open to avoid blowing on the hot glass; activate the dehumidification mode during humid episodes.
-
Filters : clean every 4 to 6 weeks during intensive periods.
-
Exterior clearance : Keep 30–45 cm free around the condenser; clear snow after storms.
Points of Attention (and How We Avoid Them)
-
Air short circuit by curtain : we position the unit and adjust the shutter to blow under the rod.
-
Condensate discharged : controlled slope and waterproof sleeve preventing any return of humidity.
-
Vibrations : anti-vibration pads and torque control on supports; flow balancing to limit resonances near the glazing.
Subsidies and energy efficiency
Modern, high-efficiency R-32/R-454B wall-mounted heat pumps may be eligible for Quebec's grant programs. We validate eligibility at the time of application and assist with the administrative process. In Montreal, Laval, and Longueuil , as well as on the North and South Shores , our team optimizes the choice of machine to combine comfort, energy savings, and program criteria.
What the customer gains in Rosemont–La Petite-Patrie
-
4-season comfort without heavy work.
-
Aesthetics : clean integration above the window, discreet capping on the courtyard side.
-
Performance : Short links = better real yields .
-
Silence : quiet operation, ideal for open kitchens.
And at your place?
Whether you are considering a Fujitsu wall-mounted heat pump , a wall-mounted air conditioner , a MultiZone Heat Pump or a central solution, we operate throughout Montreal , Laval , Longueuil , the North Shore and the South Shore . A technical visit is all it takes to precisely size the power (BTU), define the optimal route and estimate the work with firm deadlines.
Maintenance and sustainability
Annual HVAC maintenance —coil cleaning, sump disinfection, and refrigeration control—maintains efficiency, reduces odors, and extends the unit's lifespan. We offer maintenance plans tailored to urban condominiums.
In summary
A well-designed wall-mounted HVAC system installed above a window transforms a Rosemont condo into a comfortable, efficient, and quiet space year-round. That's the AirGreen promise: rigorous technical decisions, careful installation, and long-term support.
