Precise comfort and discreet finishing for a bright apartment in Verdun
At AirGreen , we have just installed a Sharp Eco Inverter wall-mounted heat pump in a bright and tidy apartment in the Verdun district. The client's goal: consistent heating in winter and quiet air conditioning in summer , without compromising interior aesthetics. The Sharp wall-mounted head with Plasmacluster technology ticks all the boxes: improved air quality, fine modulation of power, and a sober design that easily integrates into modern decors as well as more artistic interiors.
Why this choice Sharp for Verdun and Greater Montreal
Verdun's residential park alternates between renovated plexes, condos, and apartments with sometimes irregular load-bearing walls. In these contexts, we favor a compact, highly efficient, low-power wall-mounted heat pump . Sharp's Eco Inverter series is distinguished by:
-
Inverter modulation : the machine continuously adapts its capacity, ensuring savings and stable thermal comfort.
-
Plasmacluster : a built-in ionizer that reduces allergens and odors—a real plus for families sensitive to air quality .
-
Low noise level : perfect for open living areas and bedrooms.
-
High seasonal efficiency , compatible with subsidy programs in Quebec when the configuration chosen meets the efficiency criteria.
Site reading and implementation strategy
The apartment has a clear interior wall about 2.20 m below the ceiling , ideal for head placement. This height maximizes air stratification in summer and winter, while maintaining easy access for filter maintenance.
Our technical choices:
-
Install at the top , centered on the wall to promote transverse diffusion in the room and avoid cold areas.
-
Direct wall crossing at the rear of the head, limiting the apparent length of the capping inside (clean finish, visually discreet).
-
Gravity slope of the condensate drain to the outside to eliminate the need for a pump and reduce maintenance.
-
Short external path (≈ 2 to 3 m) to the condenser, installed on a raised support, which optimizes efficiency by minimizing pressure losses in the refrigerant lines.
Installation details: precision and durability
Each step of the HVAC installation was carried out to guarantee silence and longevity:
-
Fixing the mounting plate to anchors suitable for the existing support (preliminary check of the frame and level, tolerance < 1 mm).
-
Ø65 mm drilling with controlled angle for the combined outlet of refrigerant lines , drain and supply . An air barrier foam seals the crossing and prevents infiltration and thermal bridges.
-
Controlled bending of insulated copper pipes, minimum radius respected to protect the compressor and limit losses. Continuous insulation without interruption at the connections.
-
Electrical connection on a dedicated circuit with a circuit breaker compliant with the rating of the device, cable protected by conduit.
-
Nitrogen leak test , deep vacuum (<500 microns) and stabilization, then release of factory refrigerant according to actual line length.
-
Functional checks : intensity, overheating/subcooling, condensate flow, absence of vibration, noise measured at occupied distance.
Result: a silent head, without parasitic vibration, and an interior facade cleaned to leave only a delicate white cover visible, matching the wall paint.
Performance in Montreal conditions
In Montreal , rapid temperature fluctuations require machines that are stable at low speeds and capable of holding up during cold spells. The Sharp Eco Inverter delivers:
-
Efficient heating down to the negative temperatures regularly encountered in Verdun;
-
Precise air conditioning during heat waves, with humidity control that makes the air more comfortable while consuming less energy;
-
Optimized consumption thanks to modulation which avoids energy-consuming on/off cycles.
For households comparing several options (Gree, Fujitsu, Midea, etc.), this model positions itself as a reliable and balanced solution for apartments and condos in Greater Montreal .
Focus on air quality: the concrete benefit of Plasmacluster
Sharp's Plasmacluster technology emits positive and negative ions that neutralize some of the airborne contaminants. Specifically, this helps to:
-
Reduce stubborn odors (cooking, animals, ambient smoke from corridors);
-
Reduce the presence of allergens and fine dust;
-
Maintain a cooler air feeling without overheating in winter or overheating in summer.
Combined with regular HVAC maintenance , this feature really improves daily comfort.
Tips for use and maintenance to maintain performance
To maintain the advertised efficiency and extend the life of the system:
-
Filter cleaning : every 4 to 6 weeks during periods of heavy use.
-
Auto/Heat mode in winter and Cool/Dry in summer depending on humidity. Avoid excessively low/high settings; aim for 21–23°C for heating and 24–25°C for air conditioning for an excellent comfort/economy compromise.
-
Clearance : do not obstruct the blowing face (tall furniture, thick curtains).
-
Annual inspection by our technicians: residual vacuum check, cleaning of the evaporator and condenser, electrical check, flow rate and gravity drain test.
These good practices ensure controlled energy bills and stable air quality, summer and winter.
Pitfalls to avoid when moving into an apartment
We regularly encounter cases where performance is degraded by avoidable details:
-
Lines that are too long or poorly insulated: loss of efficiency and overconsumption.
-
Condensate pump not required : additional noise and unnecessary maintenance if a gravity slope is possible.
-
Wall-mounted head too low : limited air circulation, reduced comfort.
-
Leaky openings : infiltration of cold air and humidity around the passage.
Our method, proven on dozens of buildings in Montreal, Laval, Longueuil, North Shore and South Shore , consists of reducing the route to a minimum , perfectly sealing each crossing and instrumentally verifying all the parameters before handing over.
Deadlines and organization of the worksite
The Verdun configuration allows for one-day deployment for a single head with a short path . We pre-validate:
-
Co-ownership regulations (noise, balcony space, roofing colors).
-
Position of the circuit breaker and electrical protections .
-
Accessibility for tools (vacuum pump, pressure gauges, tube cutter, ladder).
The discount includes user training (remote control, modes, maintenance) and an installation report recording measurements and photos for the warranty.
And what about subsidies?
Depending on the final configuration and seasonal performance of the installed indoor/outdoor unit pair, the project may be eligible for provincial/municipal assistance . We assist our clients in analyzing eligibility and preparing the necessary documents . Our team monitors program developments to maximize the returns available in Montreal and its surrounding areas.
