Precise installation on a balcony-terrace for four-season comfort in a Montreal plex
At AirGreen , we have just completed the installation of a Sharp Eco Inverter wall-mounted heat pump in a plex in Rosemont–La Petite-Patrie, Montreal . The compact and quiet outdoor unit bears Sharp's Plasmacluster Ion badge—a technological signature that improves air quality—and operates on R-32 refrigerant , which is more efficient and has a lower GWP than older R-410A blends. Our goal: to provide reliable heating in extreme cold and efficient cooling in the summer , with a neat finish that respects the constraints of an urban balcony.
Context and challenges of the project
In Montreal plexes and condos, outdoor spaces are limited. The chosen location had to:
-
preserve traffic on the paved terrace ;
-
limit the transmission of vibrations to the structure;
-
take into account the sunshine and prevailing winds in the interior courtyard;
-
facilitate HVAC maintenance (front and side clearances for air flow).
Our advisors validated the required power based on the air-conditioned surface area, insulation and the housing's occupancy habits in order to recommend an appropriate BTU range (12 k to 18 k in the majority of cases for a unit). The chosen device, Sharp Eco Inverter (recent R-32 range) , meets Quebec's mid-season and winter heating needs while ensuring comfortable air conditioning in summer.
Visible installation details and AirGreen best practices
-
Raised aluminum support : a rigid and anti-corrosion base, ideal for balconies.
-
Anti-vibration pads (blue inserts) under the mounting flanges to reduce sound transmission.
-
Connection route : clean wall passage and white UV cover to protect the insulated refrigerant tubes and the communication cable.
-
Heights and Clearances : Positioning within recommended clearances for blowing, front panel access and service.
-
Runoff management : slope and location designed to prevent water accumulation under the unit during thawing or rainy periods.
We systematically apply a deep vacuum , a leak test (nitrogen tests) and a complete commissioning with verification of pressures, temperatures and currents. These steps determine the lifespan of the Inverter compressor and the stability of the yields.
Why Sharp Eco Inverter Technology is Right for Montreal
-
Variable speed compressor : adjusts power to actual demand, limiting on/off cycles and reducing electricity bills .
-
Low temperature heating (down to -25°C depending on the configuration) to get through the Montreal winter.
-
Air quality : The Plasmacluster Ion function helps neutralize certain particles and odors, a plus in urban environments.
-
Silent operation : crucial in the shared courtyards of Rosemont, Plateau or Villeray.
-
R-32 : better heat transfer and reduced carbon footprint compared to R-410A.
Key steps in our HVAC installation process
-
Validation of the location (noise, snow, frost, neighborhood, orientation).
-
Structural fixings and support level control.
-
Controlled drilling with interior/exterior sealing and vapor barrier.
-
Shaping of connections (clean bends, optimized lengths, absence of constraints).
-
Electrical connections comply with the Quebec Building/Electrical Code and RBQ requirements.
-
Testing and commissioning : empty, load, functional tests, operating instructions.
-
Delivery of a maintenance guide and seasonal advice.
Result: performance, discretion and aesthetics
The unit fits perfectly with the light-colored cladding and joinery of the patio door . The unobstructed airflow ensures optimal heat exchange; easy access simplifies cleaning the fins and natural defrosting in winter. The owner now benefits from:
-
stable comfort in summer and winter;
-
energy savings thanks to the Inverter;
-
of a reliable and silent system, compatible with neighborhood life.
Maintenance recommended by AirGreen
To maintain high efficiencies and extend compressor life:
-
Cleaning the internal filters every 4 to 8 weeks during periods of intensive use;
-
Visual inspection of the outdoor unit (clearances, leaves, frost) throughout the seasons;
-
Gentle washing of the fins in spring;
-
Annual HVAC maintenance visit : verification of refrigeration parameters, electrical checks, thorough cleaning and personalized advice.

Practical tips for Montreal balcony installations
-
Leave 40 to 60 cm of clearance in front of the grille for free airflow.
-
Avoid temporary obstacles (bins, bicycles, furniture) in front of the device.
-
In winter, clear snow around the support to limit defrosting cycles.
-
Program eco slots in mid-season to make the most of the Inverter.
