A careful exterior installation for four-season comfort on the South Shore
At AirGreen , we are working in Brossard on a single-family home with stone cladding. The owners want a versatile and reliable system to provide summer air conditioning and efficient mid-season supplemental heating , while controlling electricity consumption. Our recommendation is a Fujitsu wall-mounted heat pump – Orion XLTH series (R-32) , known for its stability in Greater Montreal's cold climate and its acoustic discretion. The priority is to obtain a durable HVAC installation , easy to access for maintenance and perfectly integrated into the facade.
Why choose Fujitsu Orion XLTH for Brossard
-
Cold climate performance : the Orion series maintains an excellent level of heating at low temperatures, a major asset on the South Shore .
-
Energy efficiency : inverter compressor and optimized expansion electronics to reduce operating costs.
-
Quiet operation : ideal for dense residential neighborhoods.
-
Reliability : protected components and intelligent defrosting logic to limit shutdowns during wet weather.
Site study and installation of the outdoor unit
The environment features a stone facade with a horizontal sill and a narrow green space at the foot of the wall. We are choosing to install it on wall brackets in order to:
-
clear the ground (snow, debris, grass cuttings) and protect the device from splashes;
-
facilitate the drainage of condensates in air conditioning mode by a continuous gravity slope;
-
reduce vibrations by adding anti-vibration pads .
The unit is positioned at a height that allows airflow without recirculation or obstruction by vegetation. Clearances around the air intake and outlet are maintained to maintain nominal performance and noise levels.
Execution details: aesthetics, waterproofing and accessibility
Refrigerated and electrical route
-
Unique, precisely angled drilling with abrasion-resistant sleeve and UV-resistant exterior seal.
-
Beige capping matching the moldings to conceal the connections and visually integrate with the stone facing.
-
Optimized line length (approx. 4–6 m), wide radius bends and silver brazing for long-lasting hold.
-
Communication and power cables grouped together and secured with UV clamps to prevent wind damage.
Fixings and protection
-
Hot-dip galvanized brackets , mechanically anchored in the mineral support; tensile test carried out before loading.
-
Propeller protection grid to secure the passage area and limit the intrusion of debris.
-
Installation of anti-vibration mounts under the chassis to reduce structural transmission towards the interior.
Condensate management
-
Gravity drain directed away from walking areas, with accessible inspection point.
-
Provision for a condensate pump if the interior layout requires a later discharge.
Meticulous commissioning by AirGreen
-
Nitrogen test and leak detection with electronic detector.
-
Deep vacuum draw until stabilization ≤ 500 microns; rise test to confirm absence of residual moisture.
-
Checking intensities, blowing temperatures, superheating and subcooling .
-
Setting of modes, instructions and ventilation; explanation of functions to the customer.
Result: immediate comfort, clean facade and simplified maintenance
The façade remains visually clean thanks to the capping aligned with the molding. The raised unit prevents snow buildup and leaves a clear path for grounds maintenance. The noise level remains contained, even during prolonged operation, preserving the neighborhood's tranquility.
Concrete benefits for the home
-
Uniform air conditioning of main rooms with precise humidity control.
-
Efficient heating during thaws and in the off-season, reducing the need for electric baseboard heaters.
-
Energy savings thanks to continuous modulation of the compressor.
-
Improved air quality through indoor filtration and regular circulation.
Recommended HVAC Best Practices and Maintenance
To maintain yields and extend lifespan:
-
Clean the indoor unit filters every 4 to 6 weeks during periods of heavy use.
-
Clear the area around the condenser (20–30 cm minimum on each side) and check for blocking vegetation.
-
Gently rinse the outdoor heat exchanger in spring and late summer; never bend the fins.
-
Schedule annual HVAC maintenance : check connections, pressure/temperature measurements, test sensors and drainage.
-
In winter, clear away any drifted snow that may restrict air intake.
Tips for optimizing savings
-
Maintain a stable setpoint rather than frequently alternating modes.
-
In air conditioning, aim for 23–24°C for lasting comfort.
-
Leave interior doors open to promote air circulation.
-
Use auto/low speeds in the evening to limit draft and outside noise.
