An elegant integration into a classic living room: comfort without compromise
In a cozy apartment in Côte-des-Neiges–Notre-Dame-de-Grâce , we installed a Midea wall-mounted heat pump ( wall-mounted series), positioned above a sideboard, framed by two lamps and a painting. The goal is clear: to efficiently air condition and heat a traditionally decorated living space while respecting the aesthetic coherence of the room. At AirGreen , we know that the success of an HVAC installation is not only measured by BTUs or efficiency: it is also seen in the discretion of the device, the quality of the finishes , and the reliability of the performances throughout the Montreal seasons.
Context and customer expectations
-
Four-season comfort : rapid cooling during heat waves, stable heating when the thermometer plummets.
-
Preserved aesthetics : the unit must blend into a classic decor (moldings, gilded frame, light fixtures).
-
Silence : the room is used for relaxation and reading; the noise level must remain low during continuous operation.
-
Space optimization : no encroachment on passageways or existing furniture.
Technical choice: why a Midea wall-mounted heat pump?
Midea wall-mounted units are distinguished by their compactness, fine compressor modulation , and high efficiency ; depending on the generation chosen, recent series operate on R-32 (low GWP) and maintain performance down to approximately -25°C . The wall-mounted series covers the usual power outputs (9,000 to 18,000 BTU) suitable for Montreal living rooms. It fits perfectly into urban habitats in Montreal , Laval , Longueuil , as well as on the North Shore and South Shore .
AirGreen Installation Process: Method, Finishes and Performance
Preliminary study and positioning
We first confirm that the chosen wall is exterior to allow direct drilling and a gravity drain . The high position provides better air stratification : the blowing runs along the ceiling before gently descending, which homogenizes the temperature in the living-dining room area.
Points covered:
-
Clearances : maintain the recommended distances from the ceiling and sides to avoid any air recirculation and ensure accessibility for maintenance (opening the hood, removing filters).
-
Furniture and objects : check that the shutter does not hit the lampshades or the frame; advise the customer to leave a few centimeters between the painting and the base of the unit to facilitate cleaning and avoid turbulence that could attract dust to the canvas.
-
Acoustics : choice of mounting plate and anchors suitable for the support; level control to eliminate any vibration.
Drilling, refrigeration connections and drain
-
Single crossing of approximately 65 mm with core drill, slight outward slope (1–2%) to promote gravity flow of condensate.
-
Calibrated line lengths (often 3–5 m in this type of configuration) to remain within the manufacturer's range and avoid refrigerant overloads.
-
Discreet interior cladding if required (white tint) and UV-resistant exterior capping ; clean passage along the edge to minimize the visual impact on the facade.
-
Drain management : priority to gravity ; if the slope is impossible (e.g. interior cladding not passable), installation of a silent condensate pump with non-return valve and trap to prevent odors.
Power supply and communication
We draw a dedicated power supply from the panel on a circuit breaker compliant with the device's rating. The communication cable is laid according to the manufacturer's specifications, shielded if necessary to ensure a stable connection. The routings are secured and protected to prevent any unwanted hum and premature wear.
Vacuuming, checks and commissioning
-
Flaring carried out with calibrated tools; tightening torques respected.
-
Deep vacuum (micron controlled) followed by a seal test to confirm the seal.
-
Readmission of factory fluid and possible adjustment according to the actual length of the connections.
-
Measurements : delta-T in cool/heat mode, current, superheat/subcool, drain check under load.
-
Settings : orientation of shutters , activation of night mode , programming of recovery and adjustment of eco instructions .
Result: comfort, silence and aesthetics
-
Uniform comfort in the living area thanks to laminar blowing under the ceiling.
-
Low noise level at low speeds, compatible with reading and television.
-
Aesthetics preserved : the unit blends into the decor; the wiring remains invisible from the main viewing angles.
HVAC Use and Maintenance Tips
-
Maintain a stable setpoint (22–23°C) to limit cycles and maximize durability .
-
In summer, favor dehumidification mode when the heat is moderate: increased comfort with reduced consumption.
-
Clean filters every 6 to 8 weeks under heavy use; plan for annual maintenance including cleaning the turbine, checking electrical connections and checking the drain .
-
Slightly move decorative objects away from under the unit (lamp, frame) to maintain free airflow and prevent the lampshades from being deformed by hot air.
-
In winter, turn the shutters slightly upwards to promote convection and limit the effect of drafts on the occupants.
Grants and Compliance
Depending on the configuration chosen , the wall-mounted heat pump may be eligible for assistance programs ( Energy Star criteria, low temperature performance, validated AHRI number). We support our clients in Greater Montreal in verifying eligibility , preparing documents and submitting applications , whether you are in Montreal , Laval , Longueuil , on the North Shore or the South Shore .
What we avoid…and how
-
Air recirculation : we respect the clearances on the ceiling and above the board.
-
Sound effects : rigid mounting, anti-vibration collars, fan balancing on start-up.
-
Condensate : continuous slope and load test; if necessary, lifting pump with level detector.
-
Obstacles : validation of the height in relation to the lampshades and the frame so that the shutter swings freely .
