Precise comfort in a closed room: controlled blowing above a passage, discreet gravity drainage and impeccable finishes for four-season use in Montreal.
Context: a room in Outremont that demands silence and regularity
In a bright apartment in Outremont , the client's objective is clear: to stabilize the temperature of the bedroom and the adjoining passageway without noise or drafts, while benefiting from high energy efficiency in heating and cooling. The configuration features a central opening with a molded frame, a standard ceiling and a refined decor; the interior header integrates above the lintel, optimizing diffusion without encroaching on the furnishings.
Why a Samsung wall-mounted heat pump ?
The recent Samsung wall-mounted range with R-32 refrigerant is distinguished by:
-
a responsive inverter compressor that finely modulates power to maintain a stable temperature;
-
reliable electronics for air conditioning and mid-season heating;
-
contained acoustics at low speed, suitable for night rooms;
-
an intuitive remote control with flow direction and fan speed settings.
For a bedroom and small clearance, a 9,000–12,000 BTU range covers the majority of needs without oversizing, while still providing summer dehumidification .
Installation above a passage: what we treat
We position the head above the door frame to serve the bedroom and sweep the adjacent corridor. The determining points:
-
Blowing height and angle : Orient the flaps to push the air along the ceiling, then let it fall gently, avoiding blowing directly onto the bed.
-
Clearances : minimum distances respected on the ceiling and on either side of the housing so that the sensors and suction operate correctly.
-
Service access : clear front cover for filter maintenance and periodic cleaning.
-
Acoustics : automatic speed with reduced steps at night; the high location limits interactions with obstacles (cupboards, door frames).
Refrigeration and drilling
We are choosing a short route through the back wall. This has several advantages:
-
Less pressure loss and better maintenance of heating capacity;
-
Fewer recovery points therefore less risk of internal condensation;
-
Reduced intervention time and more discreet finish inside.
The drilling is carried out with a controlled slope towards the outside. Inside, a circular bulkhead pass-through protects the insulation and prevents abrasion; on the outside, the outlet is sealed with envelope-compatible polyurethane mastic and painted if required by the co-ownership regulations.
Condensate drainage: priority to gravity
Above a passage, a reliable gravity drain is crucial. Our approach:
-
continuous slope from the drain pipe to the outlet, without counter-slopes;
-
watertight and insulated connection to prevent condensation in the partition;
-
free and discreet exterior rejection, away from the facade finishes.
Result: no internal pump, no additional noise, no tank to maintain; simplified HVAC maintenance .
Aesthetic integration and cleanliness of finishes
The room's refined style requires simple finishes:
-
passage of invisible connections in the partition;
-
alignment of the head with the lintel for a clean horizontal line;
-
maintaining a clean seal around the existing frame;
-
no visible cable protrusion, wall switch retained and accessible.
Electricity and compliance
The indoor head is powered via the outdoor unit dedicated to a protected circuit . We check:
-
the cable section according to the nominal intensity of the assembly;
-
the presence of an external proximity switch and the selectivity of the circuit breaker;
-
grounding and torque tightening to avoid overheating.
Perceived comfort: settings recommended by AirGreen
For a bedroom, we recommend:
-
Heating mode : low to medium ventilation, stable setpoint (19–21°C) to limit cycles.
-
Air conditioning mode : favor dehumidification during humidity peaks rather than excessively lowering the temperature.
-
Louver orientation : flow directed upwards and towards the corridor for gentle diffusion without direct airflow on the occupant.
Measurable result
-
Uniform temperature between the room and the adjoining corridor.
-
Low noise: the machine remains inaudible at minimum speed.
-
Aesthetics respected: no visible interior trim.
-
Simplified maintenance : accessible filters and passive drainage.
HVAC Maintenance: Simple Schedule
-
Clean filters every 6–8 weeks during the season.
-
Drain inspection at the beginning of summer and in the middle of the heat wave.
-
Exterior inspection in the fall: clearances, fastening, condition of the hood.
-
AirGreen professional maintenance every 12–24 months: pressures, temperatures, tightening, probes.
Grants and Eligibility
Recent R-32 wall-mounted heat pumps are generally eligible for various programs in effect, depending on the configuration and the system being replaced. We support our clients in Montreal , Laval , Longueuil , on the North Shore and the South Shore to validate the criteria (winter performance, installation by a licensed contractor, photo evidence, invoices).
Common pitfalls to avoid in this setup
-
Installing the head too close to the ceiling , preventing proper suction.
-
Leave a reverse slope on the drain: risk of odors and overflow.
-
Blow directly towards the rest area: feeling of discomfort and dryness.
-
Use a condensate pump when gravity is possible: noise and additional maintenance.
-
Oversize the equipment: short cycles, degraded performance and poorly controlled humidity.
