An elegant, high-rise integration, designed for a bright condo
At AirGreen , we install wall-mounted heat pumps that blend into the interior architecture while delivering stable comfort, summer and winter. In this condo in Laval-des-Rapides , close to transportation routes and the riverbanks, we are installing a Sharp known for its reliability, low noise level and improved air quality thanks to Plasmacluster Ion purification.
The context: a glazed space, a technical ceiling, specific needs
The main room benefits from a large bay window facing south. The afternoon solar gains are significant in summer, while in winter a rapid heating boost is required upon waking. The indoor unit is installed high on the wall , under an acoustic ceiling (mineral tiles), in order to:
-
clear the airflow and project the tempered air along the entire length of the room;
-
stay out of the cone of vision from the living room seat;
-
facilitate access to technical paths (drilling, supply, condensate drainage).
The vertical white casing on the right neatly groups the connections: insulated copper refrigerants, communication cable, and power supply. This finish, aligned with the doorframe, maintains a sober aesthetic and facilitates any future maintenance.
Why the Sharp solution is essential here
Comfort and silence in a condo
The Sharp Eco Inverter range is distinguished by:
-
continuous modulation (inverter) which maintains the temperature smoothly;
-
reduced noise level in both the floor and ceiling – ideal for an open living environment;
-
Plasmacluster Ion technology, which deactivates pollens and particles and reduces household odors .
In use, this results in constant comfort : gentle cooling in summer, rapid heating in the off-season, maintaining the setpoint in very cold weather with contained consumption.
Energy efficiency and new generation refrigerant
Recent Sharp models operate on R-32 , a refrigerant with reduced global warming potential , and offer high seasonal efficiencies. Coupled with good condo sealing and high-performance glazing, they allow for short compressions and long cycles at low power, which saves on the electricity bill while extending the life of the compressor.
Our AirGreen achievement, step by step
1) Preparation and checks
-
Taking measurements : distances to air returns, beam drops, top and side clearances.
-
Study of the technical route : external load-bearing wall available to the right of the unit; shortest path for connections.
-
Condensation point analysis : choice of gravity drainage thanks to a slight slope towards the outside, eliminating the noise and maintenance of a pump.
2) Millimeter positioning of the fixing plate
We fix the wall plate to metal dowels adapted to the support and check the horizontality to the tenth. This care is decisive: it guarantees the perfect flow of condensates, avoids vibrations and preserves the silence of the machine.
3) Clean and insulated drilling
-
Single small diameter borehole with controlled outward slope .
-
Insulating sleeve to prevent thermal bridges and protect connections.
-
White interior bib and capping for a clean and durable finish.
4) Refrigeration connection and vacuum draw
-
Bending without crushing copper tubes, compliant crimping, nitrogen leak tests.
-
Deep vacuum to micron, stabilized, then opening of valves to release factory charge.
-
Checking blowing temperatures and suction pressure to confirm proper fluid circulation.
5) Food and communication
The condo has a dedicated power supply to the panel; we run the line in the same enclosure to keep a compact layout. The communication cable is shielded , laid away from the power conductors to avoid any interference .
6) Commissioning and fine adjustments
-
Setting the Auto mode soft for the inter-seasons, Heat mode with Low ventilation for the winter dawn;
-
Orientation of the fins so that the flow sweeps the room without blowing directly on the occupants;
-
Customer explanations on filter maintenance and humidity management in cooling.
Installation details that make the difference
Silent gravity drainage
The drain connection runs along the right side of the unit, slopes gently down, and exits outside near the borehole. This pump-free solution is reliable and discreet .
Optimized bond length
The positioning made it possible to minimize the total length (only a few meters). A short line means reduced pressure losses , better efficiency and smoother starts .
Aesthetics and maintenance
The matte white capping aligns with the woodwork; access to the fittings and filter is less than two minutes , simplifying annual HVAC maintenance .
Results: immediate comfort, controlled bill
Upon activation, the interior temperature stabilizes quickly . The Low speed maintains a virtually imperceptible noise level ; the Plasmacluster function purifies the air after cooking and during pollen peaks. The customer benefits from a significant gain in comfort during sunny late afternoons, when the air conditioning load is usually highest in glass-fronted condos.
Grants, Compliance and Guarantees
Grants and programs
Recent high-efficiency wall-mounted heat pumps may be eligible for financial assistance in Quebec when seasonal performance and low temperature criteria are met. We support our clients in Montreal , Laval , Longueuil , the North Shore and the South Shore to prepare the file , gather proof of performance and submit the required documents.
Regulatory compliance
Our installations comply with the requirements of the RBQ and the CCQ , as well as Hydro-Québec 's best practices for dedicated circuits and electrical protection. Each site is subject to a commissioning sheet kept in your AirGreen file.
Guarantees
The manufacturer's warranty is in addition to our installation warranty . In the event of an anomaly, we intervene quickly: priority given to continuity of service and peace of mind .
AirGreen tips to ensure the longevity of your installation
Simple but regular maintenance
-
Vacuum or rinse the filters every 6–8 weeks during use.
-
Maintain clearance in front of the unit so as not to obstruct the suction.
-
Schedule annual maintenance : checking connections, checking the drain, gentle cleaning of the exchanger.
Optimal use in condo
-
In summer, set the setpoint to 24–25°C and leave the system running continuously during heat waves to avoid costly restarts.
-
In winter, leave the ventilation low to avoid stratification and direct the fins slightly towards the ceiling : the warm air is redistributed better.
Mistakes to avoid
-
Cover the capping or formwork with decorative objects;
-
Turn off the power frequently: an inverter heat pump works better in maintenance mode ;
-
Postpone maintenance: A clogged filter can increase consumption by 10 to 20% and reduce the lifespan of the appliance.
