A compact condenser perfectly integrated into a brick facade: an installation designed for four-season comfort in a Montreal plex, without noise or clutter.
A clean, durable and discreet outdoor installation
On this typical Villeray–Saint-Michel–Parc-Extension plex, we are installing a Zephyr wall-mounted heat pump . The client's objective was clear: to efficiently cool the living area in the summer and provide stable heating support in the mid-season, while preserving the aesthetics of the balcony-side facade. Our team here favors a wall-mounted installation on brackets with brown aluminum capping matching the brick, a waterproof exterior disconnect and blue anti-vibration pads under the condenser. The result: a neat, quiet and easy-to-maintain HVAC installation .
Reading the site and choosing the positioning
Architectural context
-
Red brick facade with concrete window sills and steel railings : a common configuration in Villeray triplexes.
-
Narrow balcony on the alley side: pedestrian traffic and proximity of neighbors to be considered.
-
Comfortable height available under the sill, without hindering the opening of the leaves.
Condenser positioning
-
Galvanized wall brackets fixed into masonry with chemical anchors.
-
Snow-free height for winter, while remaining accessible for maintenance.
-
Discharge of air clear of obstacles (guardrails, corner return, capping), in order to avoid the recycling of hot air in summer and to facilitate defrosting in winter.
-
Anti-vibration pads limiting structural transmission to the brick wall and guardrail.
Salient technical details
Refrigeration and finishing
-
Drilling through the brick behind the indoor unit (main room side), gravity slope for condensate drainage.
-
Brown metal capping in vertical + horizontal “L”, screwed and sealed, protecting refrigerant lines and power supply against UV and rain.
-
Estimated length of connections: 3 to 5 m , including anti-vibration loop at the unit outlet.
-
Continuous closed cell insulation (no thermal bridges), UV tape and vapor barrier caps at the ends.
Power supply and safety
-
Waterproof outdoor disconnect box , operable without tools, installed within reach while remaining outside the runoff zone.
-
Dedicated panel circuit breaker , rated according to the system nameplate.
-
Grounding checked and torque meter tightening on the terminal blocks.
Noise control
-
Compliant clearances around the propeller; pads + robust brackets = almost zero vibrations in the guardrail and the apartment.
-
Orientation of the breath away from windows and neighbors to preserve the tranquility of the alley.
The Zephyr solution for a Montreal plex
Performance and comfort
The selected Zephyr wall-mounted heat pump offers inverter modulation that adjusts power to actual needs. In summer, cooling is gradual and uniform ; in mid-season, heating stabilizes the temperature smoothly. The control electronics optimize defrost cycles, which prevents drops in comfort in humid weather.
Air quality and maintenance
-
Washable filters accessible from the front of the interior head.
-
Easy to clean coil and condensate tray during annual HVAC maintenance .
-
Outside, a simple clearance of leaves/snow and a visual inspection of the connections are sufficient between two visits.
We always confirm the exact BTU capacity and electrical settings from the technical documents and the appliance nameplate to ensure accurate sizing.
AirGreen Method: rigor at every step
-
Preliminary checks : brick structure, center distance of uprights, layout of connections, gravity drain point.
-
Drilling and sheathing : crown drill bit, sleeve and outer sealant for a waterproof envelope.
-
Connections : flaring with calibrator , tight torques according to Zephyr, nitrogen flushing.
-
Leak testing at 300 psi and deep vacuum (≤ 300 microns), stabilization and ascent control.
-
Load release , cooling and heating tests, supply/return temperature and intensity measurements.
-
Finishes : fitted capping, UV collars, waterproof cable gland , maintenance instructions provided to the customer.
Sizing and actual comfort
What we calculate before installing
-
Surface area and volume of rooms served.
-
Orientation and solar gains.
-
Level of insulation of the plex, quality of the windows, possible infiltrations.
-
Use of the room (occupancy, heat-generating devices).
Target capacity
In this project, the main living area + hallway require a range of 12,000 to 15,000 BTU depending on seasonal losses. The chosen configuration allows the machine to work for a long time at low speed , guaranteeing silence , energy savings and durability .
Urban integration: aesthetics and regulations
-
Brown capping matching the brick and painted lintels.
-
Drilling reduced to the bare minimum.
-
Compliance with the clearances required by the manufacturer.
-
Wall installation which frees up the balcony floor , a priority for small terraces in Villeray.
-
Advice provided to the customer on snow removal and anti-icing protection if necessary (deflector, light awning, snow guard).
Grants and Eligibility
High-performance wall-mounted heat pumps serving Greater Montreal may be eligible for assistance programs (depending on the capacity maintained in cold weather and the required certifications ). We validate each file and provide the supporting documents required for applications in Montreal , Laval , Longueuil , as well as on the North Shore and the South Shore .
Maintenance: simple and effective plan
By the customer
-
Clean filters every 4–6 weeks during use.
-
Clear 30–60 cm around the condenser (leaves, snow, objects).
-
Set a stable temperature and avoid sudden variations.
By AirGreen (annual)
-
Deep cleaning of the interior head (evaporator, turbine, tray).
-
Complete electrical inspection , terminal torque, probe check.
-
Overheat/subcooling check, parameter update.
-
Photo report with personalized recommendations.
Common mistakes… that we avoid
-
Condenser placed on the balcony floor : vibrations and frost. Here, brackets + pads = stability and longevity.
-
Exposed refrigeration path without protection: we install a robust, screwed and sealed capping .
-
Backdraft directed toward a window : noise and discomfort. We orient the unit to direct the blast away from the openings.
-
Non-gravity drain when gravity is possible: more noise, more maintenance. Here, we favor gravity .
Usage tips for constant comfort
-
Cooling : aim for 24–25°C with Auto ventilation for a uniform atmosphere.
-
Heating : 21–22°C , shutters slightly downwards to limit stratification.
-
Dry mode for very humid days: dehumidification increases the feeling of comfort without overcooling.
-
Open doors to adjacent rooms to expand the comfort zone.
