Four-season comfort in Chomedey thanks to a neat and discreet HVAC installation
Context and objectives of the project
In Chomedey, Laval, a family wanted a compact system capable of providing supplemental heating in the shoulder seasons and efficient cooling in the summer, with quiet operation for an open-plan living space. We recommend a Haxxair R-32 wall-mounted heat pump (capacity matched to the room) for its compact size, balanced seasonal performance, and discreet design.
Why the Haxxair R-32 Wall Mounted Series?
-
R-32 refrigerant, lower GWP than R-410A.
-
Competitive seasonal yields and fine inverter modulation to maintain a stable temperature.
-
Low interior noise level, ideal for living/dining room.
-
Smart defrosting and performance maintenance in cool weather — a real plus for the North Shore .
Technical analysis of space
-
Standard ceiling height with crown molding: install the head at the correct distance from the ceiling for optimal airflow.
-
Load-bearing wall providing direct access to the exterior: short refrigeration path (≈ 2.5 to 3 m), which limits pressure losses and improves the actual COP.
-
Opening near a passage/door: check lateral clearances to avoid air recirculation.
HVAC Installation Details (Wall)
-
2–2.5 in. through -hole with gravity slope for condensate drainage.
-
Clean wall outlet : discreet white capping coordinated with the interior finish.
-
Insulated and taped refrigeration connections, direct passage to the outside to limit bends.
-
Exterior installation (not visible here) planned on sturdy wall brackets , clear of the ground for snow and maintenance.
-
Electrical connections according to current code, dedicated circuit breaker recommended, grounding verified.
Condensate management
The positioning at the top of the wall allows for gravity drainage to the outside. A continuous slope is ensured; a service point remains accessible for seasonal cleaning. No condensate pump is required, ensuring additional silence and reliability.
Commissioning and checks
-
Deep vacuum and leak test.
-
Load compensation if necessary depending on the actual length of lines.
-
Checking blown temperatures, subcooling and superheat to validate operating range.
-
Auto sweep and speed settings for consistent comfort throughout the living area.
Result: comfort and discretion
The customer notes:
-
A stable temperature without drafts, even in auxiliary heating mode in cool weather.
-
A sound level that is almost imperceptible in steady state.
-
A clean look that blends with the ceiling molding and light finishes in the room.
HVAC Maintenance Tips
-
Clean the filters every 4 to 6 weeks during use.
-
Annual maintenance by a technician: cleaning of the evaporator, checking of the drain, electrical inspection, washing of the outdoor unit.
-
Spring check of free clearance around the condenser (foliage, dust, packed snow).
Sizing and best practices
-
Capacity chosen according to the surface area, orientation, insulation and internal gains (kitchen, appliances).
-
Refrigeration path as straight as possible to maintain efficiency.
-
Respect clearances above and around the interior head for optimal air diffusion.
-
Programming Dry mode in mid-season for better hygroscopic comfort.
Grants and eligibility (typical cases)
Many models of high-performance wall-mounted heat pumps with recent refrigerants are eligible for provincial programs when their technical data sheets meet the required thresholds (efficiency and performance in cold weather). We systematically verify eligibility and prepare the file for our clients in Montreal , Laval , Longueuil , South Shore and North Shore .
