Installation of a GREE Livo R32 wall-mounted heat pump in Chomedey (Laval)

A thoughtful installation under the balcony for stable performance all year round

At AirGreen , we are responsible for the HVAC installation of a GREE Livo R32 wall-mounted heat pump in a house in the Chomedey sector of Laval . The objective: to offer four-season comfort with a protected outdoor installation under a balcony , without compromising on airflow , durability and ease of maintenance . The chosen configuration combines a short connection passage, careful management of the condensation drain and an elevation on a metal support to preserve performance in both winter and summer.

Project context and client expectations

The owner wanted:

• reliable additional heating in very cold weather, to reduce your electricity bill;

• precise and quiet air conditioning in living areas;

• a discreet installation, with no visual impact on the courtyard;

• a recent R-32 system, compatible with the grant programs applicable in Greater Montreal (Montreal, Laval , Longueuil, North Shore , South Shore ).

We recommended the GREE Livo R32 , a wall-mounted heat pump known for its high seasonal efficiency , its inverter compressor and its operating stability in cold climates.

Choice of location: sheltered, ventilated, accessible

The outdoor condenser is installed under a wooden balcony , sheltered from direct precipitation and summer solar radiation. To comply with the rules of the art:

• We have ensured sufficient clearance above and in front of the fan for air circulation and defrost cycles.

• The unit rests on a raised galvanized steel base , fixed on concrete slabs and a clean stone bed for perfect drainage and better stability .

• Anti-vibration pads limit sound transmission to the balcony structure.

• The connection capping (light gray color) protects the insulated refrigeration pipes , the power cable and the drain , while making the assembly discreet and easily accessible for HVAC maintenance .

This installation optimizes the longevity of the compressor, prevents snow accumulation around the unit and facilitates service .

Link path and condensate management

We choose a short, straight route between the interior head and the condenser to reduce pressure losses and maximize efficiency . The condensation drain is led into the same chute and then directed to a suitable evacuation point, promoting gravity flow and avoiding any risk of dripping onto the facade . The jointing at the drilling is carried out with sealing foam and vapor barrier to preserve the watertightness of the envelope.

Why the GREE Livo R32?

The Livo R32 range is part of GREE's new R-32 platforms. It features:

• a variable speed compressor that finely modulates power;

• high seasonal efficiency in cooling (SEER) and heating (HSPF), conducive to energy savings ;

• a heating operating range adapted to the climate of the North Shore ;

• a contained noise level , both on the interior side and on the condenser side;

• washable filters and easy access to components for maintenance .

Depending on the area served, the range offers capacities from 9,000 to 24,000 BTU , which allows the device to be precisely adjusted to the actual needs of the home.

Key steps in our installation

1. Thermal assessment of the main parts and identification of the shortest holes.

2. Laying the raised support : checking the level, mechanical sealing, compacted stone bed for stability and drainage.

3. Connections : dehydrated refrigeration copper, controlled bends , high density insulation, nitrogen leak tests .

4. Deep vacuum with calibrated pump, vacuum resistance control and opening of service valves.

5. Dedicated electrical connections , in accordance with the Code, with suitable circuit breaker and external disconnect switch .

6. Start-up and calibration : verification of temperature deltas in cold/heat modes, ventilation speed , and customer training in eco modes .

Finish and aesthetics: maximum discretion

The gray capping blends into the vinyl siding of the foundation. The curvature radii at the condenser outlet are generous to maintain connections and avoid wear points. The condenser's installation height , combined with the balcony's shelter, protects the unit from:

• blown snow ;

• ice on the ground;

• runoff water during thaws.

Results obtained

Upon commissioning, the customer notes:

• temperature stability in the open area;

• very low perceived noise under the balcony and inside;

• rapid response to load variations thanks to the inverter ;

• a reduction in on/off cycles , a guarantee of durability .

Best practices and pitfalls to avoid (AirGreen feedback)

• Always maintain the required clearances around the condenser, even under a balcony: free space on the facade and above is essential for air flow and defrosting .

• Raise the unit above the anticipated snow level and provide a drainage plan (clean stone + slabs) to avoid puddles and corrosion .

• Limit the length and bends of the connections: the shorter the route, the better the efficiency .

• Protect the condensation drain from freezing and ensure a continuous slope .

• Avoid overly closed recesses : insufficient air volume leads to increases in static pressure and a drop in efficiency.

• Plan maintenance : a poorly accessible location complicates periodic checks (coils, connections, pressures).

Recommended HVAC maintenance

To maintain the performance of the wall-mounted heat pump :

• Cleaning the inner head filters every 4 to 8 weeks during periods of heavy use;

• Annual inspection by our technicians: pressures, temperatures, connections, condition of the capping , electrical tightening;

• Clearances around the condenser: remove leaves, dust and any obstruction to the air flow ;

• Check the drain when the snow melts and at the beginning of summer.

Regular maintenance extends the life of the device and maintains performance coefficients .

Grants and Eligibility
