Four-season comfort and discreet integration into a neat interior
At AirGreen , we tailor each HVAC installation to the lifestyle and architecture of the home. In this Rosemont–La Petite-Patrie (Montreal) apartment, the goal is clear: consistent year-round comfort, controlled energy consumption, and flawless aesthetic integration into the living area. We selected a Midea Mission wall-mounted heat pump , an inverter range renowned for its consistent performance in cold climates, quiet operation, and understated finish—perfect above the furniture and large round mirror in the living room.
Why Midea Mission is essential for this project
Our recommendation is based on concrete criteria for apartments in Montreal:
-
High heating and air conditioning efficiency thanks to the inverter compressor which precisely modulates power and avoids jolts.
-
Silence and soft diffusion : ideal for an open living room where you cook, work and entertain.
-
Visual sobriety : the smooth facade and discreet edging match the light wall and interior arches.
-
Frequent eligibility for grants when the chosen configuration meets the required performance thresholds; we support the verification of criteria and the preparation of parts.
An exemplary project by AirGreen
We approach this type of HVAC installation with a proven method to guarantee performance, reliability and impeccable finishes.
Locating and positioning the inner head
We place the head approximately 2.15 m from the floor to optimize vertical sweeping and avoid any direct blowing onto the occupants. The perfectly flat partition wall offers:
-
an alignment centered above the side table and the mirror,
-
uniform clearance on the ceiling to limit air recirculation,
-
a very short passage of the connections to the outside, which improves the overall efficiency and reduces losses.
We check the load-bearing capacity , the built-in elements (electricity, plumbing), and the compatibility with the light framework typical of Montreal plexes.
Drilling, sealing and protection of connections
-
Creation of a rear drilling with a gentle slope (≈ 5°) to ensure a gravity drain — more reliable and quieter than a condensate pump.
-
Installation of a sheath and a vapor barrier seal to preserve the airtightness of the envelope and prevent infiltration of cold air or humidity.
-
External outlet under discreet, light-colored capping , protecting the insulated refrigeration pair and the communication cable.
The whole thing is sealed cleanly; the screws are hidden and we apply a light acrylic seal around the edge of the support for a neat wall finish.
Power supply and compliance
We draw a dedicated power supply from the housing panel, sized according to the unit's nameplate, with a double-pole circuit breaker and disconnection means near the condenser. The structure complies with RBQ/CSA requirements and good grounding practices. The routing follows the shortest route and remains perfectly integrated into the existing system.
Installation of the outdoor condenser
On the backyard side, the Midea condenser is mounted on galvanized wall brackets with silent blocks to absorb vibrations. We respect the clearances for air intake and winter defrosting and provide:
-
a defrost drain pipe away from traffic areas,
-
stainless steel fasteners, anti-corrosion treatment of the cuts,
-
the possibility of adding a snow guard if the exposure justifies it (drafts and accumulations).
Vacuuming, testing and configuration
After deep vacuum drawing and stabilization, we validate the watertightness; we adjust the load if the actual length requires it, then we carry out:
-
delta-T readings in cold and heat,
-
current measurement and power factor verification,
-
adjusting the vertical sweep so that the flow bypasses the seating area and spreads along the wall,
-
activating useful functions such as Follow Me (temperature sensor on the remote control) and Dry mode for controlling summer humidity.
Immediate results for the customer
-
Uniform temperature in the open area (living room-dining area-circulation).
-
Low noise : at low speed, the unit blends into the sound environment of the home.
-
Optimized consumption : the heat pump takes care of the majority of needs, reducing the use of electric baseboards.
-
Preserved aesthetics : no visible conduits in the living room; the white facade matches the minimalist decor.
Sizing: Just right
For this typical Rosemont volume (25–35 m²), we recommend the 9,000 to 12,000 BTU/h range depending on the orientation, the glazed surface area and the airtightness. We systematically carry out a load estimate to avoid over- or under-sizing, two errors that harm both comfort and energy bills.
Humidity and air quality management
In summer, we recommend aiming for 45–50% RH . The Mission handles drying well without overcooling when left in Auto speed. We also recommend:
-
monthly cleaning of the filters during periods of heavy use,
-
partial opening of adjacent doors to promote air transfer ,
-
the occasional check of natural return vents to avoid stagnation.
Preventive maintenance: the key to longevity
Annual HVAC maintenance by our teams maintains performance and protects warranties:
-
electrical inspection and insulation checks,
-
checking the tightness of the refrigeration circuit,
-
cleaning the coils (gentle method or chemically infused cloth depending on the condition),
-
control of blown temperatures and superheat/subcooling .
We document each visit to facilitate, if necessary, the grant and guarantee procedures.
Grants and administrative support
Several Midea configurations meet the performance thresholds required by active programs in Quebec. We guide our customers in Montreal, Laval, Longueuil, North Shore and South Shore in:
-
eligibility verification ( Energy Star , low temperature heating capacity),
-
collecting proof of installation (photos, serial numbers, detailed invoice),
-
the filing of applications within the required time limits.
Good practices for daily use
-
Maintain a stable setpoint (e.g. 22°C); the inverter works better in continuous modulation than in on/off mode.
-
Use Follow Me when sitting at the table or on the sofa for more targeted comfort.
-
Switch to Heat mode early in the fall to avoid cold starts.
-
In summer, use Auto speed in the evening to gradually lower the humidity.
What we monitor in Rosemont housing
Partition walls and openings near corners require precision. We take care of:
-
the flatness of the support to avoid vibrations,
-
the visual axis with decorative elements (mirrors, lights),
-
the slope of the drain to remain 100% gravity-based and avoid any odors rising.
