Installation of an Elios Moovair (R-32 range) wall-mounted heat pump in Côte-des-Neiges–Notre-Dame-de-Grâce

Four-season comfort in an urban NDG living room: a compact, elegant installation ready for Montreal winters

Client context and objectives

At AirGreen , we are working on a renovated apartment in Côte-des-Neiges–Notre-Dame-de-Grâce . The owner wanted a discreet HVAC solution to cool the living room in the summer and support the heating in the off-season, without major renovations or wasted space. Priorities: silence , efficiency , aesthetics , and reliability in extreme cold.

We offer a wall-mounted Elios Moovair heat pump (R-32 range) , 12,000 BTU configuration - sized after a simplified load calculation (surface area, orientation, insulation, internal inputs). This capacity typically covers 400 to 600 sq. ft. in an open living area, with a comfortable margin for peaks.

Why the Moovair (R-32) range meets the need

• R-32 refrigerant : better seasonal efficiency than R-410A and reduced charge for the same power.

• Seasonal efficiency : Competitive SEER/SCOP, ideal for reducing annual consumption.

• Operation in cold weather : maintaining useful capacity around −25°C , essential for Montreal , Laval , Longueuil , North Shore and South Shore .

• Acoustics : very low interior noise level, suitable for open living spaces and terraced apartments.

• Design : minimalist facade integrated into the decor; compact size above the wall elements.

Installation process — clean, fast, controlled

Preparation and tracing

We validate the location at height (~2.20 m) for optimal air diffusion above the furniture and away from heat sources. The installation template is fixed with a laser; we identify the shortest cross to the outside and the route of the connections.

Drilling and passing lines

• Wall crossing to the required diameter with controlled negative angle.

• Installation of insulated refrigerant connections, communication cable, and power supply.

• Discreet white capping near the outlet for a neat finish and easy maintenance.

Condensate management: compact and quiet pump

Since gravity drainage is not possible (horizontal path imposed by the architecture), we install a condensate pump under the interior head. Advantages:

• No visible gutters and no additional drilling in the baseboard;

• Safety (level sensor with safety stop);

• Easy maintenance (accessible hatch).

Connection, vacuuming and commissioning

• Calibrated flares and tightening torques respected;

• Deep vacuum with micronmeter until stable;

• Leak check and R-32 refrigerant charge according to actual length;

• Settings: blowing mode, sweeping , and set temperature;

• Measurements of blowing temperature, intensity, and delta T under load.

Aesthetic result and thermal comfort

The wall head integrates into the decor (frames, wall light). The wiring is contained; the condensate box remains compact and harmonized. In use:

• Responsive and homogeneous cooling of the living room in summer;

• Efficient additional heating in autumn and spring;

• Low noise level , ideal for teleworking and home cinema.

Sizing tips for similar spaces

• 9,000 BTU : Well-insulated bedrooms/offices up to 350 sq. ft.

• 12,000 BTU : Living rooms 400–600 sq ft, open plan.

• 18,000 BTU and up : large open areas, high ceilings or multiple doors.
  A load calculation by our advisors remains the reference to avoid over-sizing (short cycles, discomfort) or under-sizing (noise, wear).

Technical points to remember about this pose

• Controlled working height , clearances respected for air intake and maintenance.

• Short link length (better efficiency).

• Discreet path via capping and ceiling; no visual impact.

• Condensate pump with high level cut-off to prevent any risk of flow.

• Dedicated power supply and compliant protections.

HVAC Maintenance: The Key to Performance

To maintain performance and longevity:

1. Filters : clean every 4 to 8 weeks during the season.

2. Evaporator battery : gentle dusting; avoid corrosive products.

3. Condensate pump : check the tank and float at the start of summer.

4. Outdoor unit (if accessible): minimum clearance of 30 cm, cleaning of the fins.

5. Annual AirGreen inspection : pressure/consumption check, condensate test, electrical check.

Regular HVAC maintenance reduces consumption by up to 10–15% and extends equipment life.

Energy subsidies and savings

Depending on the Energy Star configuration and performance at −25°C , a wall-mounted heat pump like the Moovair (R-32) may be eligible for assistance in effect in Quebec (municipal/provincial programs). We support our customers in:

• Check eligibility;

• Prepare evidence (model, serial numbers, photos);

• Optimize the usage strategy (stable setpoint, automatic ventilation, seasonal programming).

Common Mistakes to Avoid (and How We Prevent Them)

• Installation too low → air recirculation and discomfort: we respect the manufacturer's clearances.

• Improvised gravity drain without slope → risk of infiltration: here, pump sized and tested.

• Connections too long → loss of capacity: layout designed for compactness .

• Absence of controlled vacuum → humidity in the circuit: we aim for a deep vacuum measured with a micron meter.

What the customer actually gains

• Immediate summer/winter comfort in the living area.

• Lower bills compared to traditional air conditioning and electric baseboard heaters.

• Real estate value : modern, aesthetic, and sought-after equipment in NDG.

• Peace of mind : guaranteed AirGreen installation and local after-sales service.
