Installation of a CanAir Inverter wall-mounted heat pump in Chomedey

Installation on brackets on a brick facade: compact, silent and ready for the Laval winter

At AirGreen , we treat every HVAC installation as a full-scale engineering project. In Chomedey (Laval) , we have just equipped a brick house with a CanAir inverter wall-mounted heat pump . The outdoor unit is mounted on wall brackets , clear of the ground to avoid snow and shocks, with a discreet UV cover on the connections and an outdoor disconnect switch within easy reach. The result: a solution that frees up the parking area, reduces perceived noise and improves four-season efficiency.

Client background and objectives

The owner wanted:

• effectively air-condition the living area in summer;

• heat stably and economically in winter in order to limit the use of baseboards;

• maintain ground clearance for snow removal and traffic.

After a thermal assessment and inspection of the facade, we selected a CanAir monosplit configuration , sized in the usual capacities of 9,000 / 12,000 / 18,000 BTU according to the calculated loads. Inverter technology allows for fine adjustment of power and lower consumption.

Outdoor installation: sturdy brackets and reliable anchors

Why brackets?

• They raise the condenser above snow and defrost puddles.

• They clear the driveway and protect the unit from shovels, bicycles and children playing.

• They facilitate maintenance : all sides remain accessible.

Our implementation:

• Galvanized brackets with high load-bearing capacity, with safety margin.

• Anti-vibration pads under the base to decouple the device from the masonry.

• Mechanical/adhesive anchors in sound brick (never in the joint alone), tightened to the torque.

• Level control and service loop behind the unit to eliminate any stress on the flares.

Water and frost management:
In heating mode, defrosting discharges water. The elevation limits the risk of ice on the floor. If the configuration requires it, we add a discreet deflector to channel the drip and prevent streaks on the brick.

Refrigerated and electrical path: short, protected and aesthetic

• Insulated copper refrigeration lines , most direct path possible to reduce pressure losses.

• UV-resistant rigid cover on the front; clip-on covers for quick maintenance .

• External disconnector installed in the immediate vicinity of the condenser to make interventions safer .

• Grouped communication and power cable , bending radii respected to preserve the insulation.

• Core drilling, closed cell foam and sealant to ensure airtightness .

Notable technical details of this installation

• Fan guard to prevent debris intrusion.

• Blue fins with hydrophilic/anti-corrosion coating on the exchanger, useful against humidity and de-icing salt.

• Cladding and brackets chosen in a neutral shade for visual integration with the brick.

• Disconnector mounted on rigid support, with waterproof conduit to protect the wiring.

Commissioning: rigor and traceability

Our technicians apply a constant protocol which ensures the reliability of the refrigeration circuit :

1. Calibrated flares and torques checked by dynamometer.

2. Nitrogen pressurization and control with foaming solution then electronic detector .

3. Deep vacuum (≤ 500 microns ), maintenance and ascent test .

4. Refrigerant release, superheat/subcooling validation.

5. Intensity measurements, supply/return temperatures , and noise and vibration verification.

6. Comfort settings (modes, speeds, settings) according to occupant usage.

Each step is recorded to provide traceability useful for after-sales service and grant programs .

Everyday comfort and performance

• Continuous modulation : the heat pump adjusts its speed to maintain the temperature smoothly.

• Improved dehumidification in summer thanks to long and stable cycles.

• Maintains useful capacity at low temperatures (depending on version), adapted to the climate of Montreal and Laval .

• Reduced noise level both outside and inside, appreciable in close proximity.

HVAC Maintenance: Simple, But Critical

To maintain performance and low consumption:

• Indoor unit filters : Clean every 4–8 weeks during use.

• Condenser : visual inspection every season; removal of leaves, dust, snow.

• Condition of brackets and buffers : annual check, tighten if necessary after the first winter.

• Batteries : Gentle washing and temperature/pressure checks as part of an annual HVAC maintenance visit.

• Hood : check the integrity of the covers, especially after very cold weather.

AirGreen offers maintenance plans adapted to the realities of Montreal, Laval, Longueuil, North Shore and South Shore .

Common Mistakes Avoided by AirGreen

• Anchoring in the joint : random hold. We fix in the solid brick .

• Undersized brackets : vibrations and noise. We select certified brackets with a safety margin.

• Incomplete cover : UV and birds damage the insulation; we closed each segment .

• Insufficient drain slope on the interior side: risk of flow; we guarantee a continuous slope and service access .

• Oversizing : short cycles and discomfort; we size to the real needs of the accommodation.

Grants and support

Many CanAir inverter heat pumps meet the energy efficiency criteria required by current grant programs (e.g., provincial and federal initiatives where available). We support:

• eligibility verification (measured yields, low temperature maintenance, Energy Star where applicable);

• documentation (detailed invoice, AHRI number , installation photos if necessary);

• support until receiving help.

Bottom line: a clean, sustainable facility ready for the local climate

This CanAir wall-mounted heat pump, installed on brackets , delivers the expected four-season comfort while preserving floor space and the integrity of the facade. The short refrigeration path , careful sealing and rigorous vacuuming guarantee optimized operating costs and increased longevity .

AirGreen operates daily in Montreal, Laval, Longueuil, on the North Shore and the South Shore for heat pump installations, replacements and HVAC maintenance . We provide clear advice , controlled installation and measurable follow-up .
