An interior header perfectly positioned above the media wall, a short and discreet path to the exterior, and controlled air diffusion: this project illustrates our HVAC installation approach focused on real everyday comfort.
A clear mandate: targeted comfort, careful integration
In this bright Verdun apartment, the owner wanted to air condition the living room, which was equipped with a wall-mounted television, without any visible cables or noise pollution. We recommended a Gree wall-mounted heat pump (new generation R-32 ), selected for its excellent efficiency/silence compromise, its stability in mid-season heating mode and its compatibility with energy efficiency programs applicable to Greater Montreal.
Performance objectives
-
Rapid cooling in the late afternoon, sunny facade.
-
Supplemental heating in fall and spring to reduce reliance on baseboards.
-
Minimum sound level so as not to disturb TV viewing.
-
Impeccable finish: no invasive cable ducts or visible cables.
Layout design: position is 50% of the result
The wall head is placed high, to the left of the window , with uniform clearance to the ceiling. This placement offers:
-
Optimal range : the flow runs along the ceiling before descending, which evens out the temperature without direct air currents on the sofa.
-
Glazing management : the treated air compensates for solar gains close to the window, limiting “hot pockets”.
-
Aesthetic consistency : the blowing axis remains outside the main visual field and aligns with the wall-mounted television.
Route of the connections: short, clean, efficient
-
Side outlet near the corner; direct drilling towards the outside to maintain a connection length of ≈ 2.0 to 3.0 m (copper, drain, cable).
-
Condensate drainage by gravity with continuous slope; zero pump = less noise, less maintenance.
-
2-1/2" drilling with vapor barrier, high density insulation and exterior sealing with neutral silicones.
-
Internal anti-vibration fixings and controlled tightening torque on flared fittings.
AirGreen Methodology: Good Practices That Pay Off
We systematically apply the following steps for all HVAC installations :
-
Bending of copper tubes and brazing under nitrogen to protect the interior of the pipes.
-
Nitrogen pressure for leak testing, then deep vacuum ( ≤ 500 microns ) and stabilization.
-
Electrical management on a dedicated circuit with compliant earthing and clear marking on the panel.
-
Setting of shutters and airflow according to the actual volume of the room and the media configuration.
-
Finish : invisible fittings, stainless steel screws, verified alignments and tight joints.
Measurable results: comfort, silence, savings
-
Summer comfort : rapid drop in temperature and humidity, without direct airflow thanks to the wide horizontal sweep.
-
Interseasonal heating : gentle heat in the morning and evening, with controlled consumption thanks to the high seasonal efficiency R-32 refrigerant.
-
Acoustics : very low interior noise level; no vibration transmitted to the media wall.
-
Aesthetics : discreet integration into the gray wall, no visible cables around the television.
Sizing: avoid over-equipment
In a Montreal condo living space, a well-placed 9,000 to 12,000 BTU unit is generally sufficient. We favor:
-
One head per living area rather than just one that is too powerful (limits “short cycling”).
-
Multi-zone only if the rooms are far apart or on several levels.
-
Shortest possible run to keep SEER/HSPF close to nominal values.
HVAC Maintenance: Maintaining Performance
-
Wash filters every 4–6 weeks during use.
-
Annual professional cleaning of the battery/fan wheel.
-
Checking the slope of the drain and the sealing of the crossings.
-
Clearing the outdoor condenser (vegetation, dust, snow).
-
Update of operating modes (cooling/maintenance/heating) according to the season.
Pitfalls avoided on this site
-
Condensate pump unnecessary: gravity route preferred.
-
Drilling too low which lengthens the drain: we stay under the ceiling to reduce oil pressure losses and promote drainage.
-
Disturbed visible TV wiring : the layout takes into account the media wall, no crossover with the audiovisual supply.
-
Excessive connections : direct route to the facade, minimized losses.
Grants and Eligibility
Recent R-32 wall-mounted heat pumps with good heating performance in cold weather may be eligible for assistance programs in Quebec. AirGreen verifies the eligibility of the installed model, prepares supporting documents (certificates, performance parameters) and supports owners in Montreal , Laval , Longueuil , on the North Shore and the South Shore .
