Installation of a GREE wall-mounted heat pump in Griffintown

Four-season comfort perfectly suited to Southwest industrial-style condos

At AirGreen , we have just completed the installation of a GREE wall-mounted heat pump in a condo in Griffintown (Le Sud-Ouest, Montreal) . The space features an exposed concrete ceiling and visible ducts—typical architecture for the area—which requires precise, discreet, and sustainable HVAC integration . Our mandate: to provide reliable heating in winter and consistent air conditioning in summer , with consumption optimized for Montreal's energy realities.

Why a GREE wall-mounted heat pump for a Griffintown condo?

The neighborhood's contemporary residences combine large bay windows , open spaces , and varying ceiling heights . A wall-mounted heat pump perfectly meets these constraints:

• inverter modulation to provide only the required energy;

• wide front air diffusion, ideal for open-plan rooms ;

• reduced noise level to preserve the tranquility of an urban condo;

• R-32 refrigerant on recent GREE ranges, with a lower GWP than R-410A.

The GREE brand is one of the benchmarks in the residential market and offers, in its Airy R32, Livo R32, Clivia R32, Vireo R32 and other series, devices designed for the Montreal climate with stable performance down to −25 °C depending on the range.

Project context and selection criteria

The client wanted:

1. Thermal stability all year round without variations;

2. Neat aesthetics despite the raw style of the ceiling;

3. Simple maintenance and easy access to filters;

4. Noise optimization to respect the co-ownership.

After calculating the thermal loads and analyzing the solar gains specific to the orientation of the condo, we recommended a GREE wall-mounted heat pump of suitable capacity (range 9,000 to 12,000 BTU for the main zone; exact dimensions validated on site), compatible with eco-performance criteria and subsidies where applicable.

Architectural integration: precision and discretion

The indoor unit was positioned high on the wall , under the concrete slab, in order to:

• maximize the Coanda effect and achieve minimal stratification ;

• avoid any short recirculation against the ceiling;

• maintain clearances in accordance with manufacturer specifications.

The passage to the outside is covered and insulated , with a white finish that blends in with the wall paint . The wall support is anchored to studs, and vibrations are dampened by buffers to prevent propagation to the rigid structure of the building. The condensate drain is oriented for secure gravity flow ; a pump is only considered if the architecture requires it, which reduces maintenance and noise.

Routes of connections and energy performance

The refrigeration route is designed to be short and direct , limiting pressure losses and preserving seasonal efficiency . We use:

• high density insulated copper lines ;

• a watertight seal of the drilling (air/water) to avoid thermal bridges and infiltration ;

• sufficient service reserve for subsequent interventions.

Upon commissioning, we carry out:

• deep vacuum and leak test ;

• checking for overheating/subcooling according to the machine range;

• measurement of supply and return temperatures to ensure optimal ΔT .

Result: homogeneous diffusion, silence and aesthetics respected

In cooling mode, the air blade efficiently covers the living-kitchen area. In heating mode, the inverter algorithm maintains a stable temperature without jolts. The discreet front display makes it easy to read the setpoint, and the washable filters can be removed in seconds—a plus for regular HVAC maintenance .

Technical features of condos with concrete ceilings

In units with exposed ceilings , several points deserve expert attention:

• Acoustic reverberation : we favor adjusted ventilation speeds and positioning that avoids echoes on the slab.

• Anchors : assembly is done on a partitioned wall with the uprights marked; drilling into the slab is avoided unless otherwise specified by engineering.

• Condensates : a constant slope is ensured; in the absence of gravity, we integrate a silent pump with flow stopper to prevent any return.

Exterior: best practices for co-ownership (summary)

Even if the image shows the interior unit, our team systematically applies, on the exterior side:

• wall brackets or platform with anti-vibration pads ;

• clearances for fresh air and defrosting ;

• management of drips in winter to prevent ice formation;

• protected wiring and code-compliant circuit breaker .

These practices ensure an HVAC installation that complies with Griffintown condominium regulations and Montreal 's dense environments.

Grants and Eligibility

Recent GREE R-32 ranges offer high efficiencies (SEER2/HSPF2 depending on the model). When a model is Energy Star certified and offers sustained performance in cold weather, it can open the door to provincial or municipal financial assistance . We guide our clients in preparing files and choosing the most advantageous capacity/efficiency combination for Montreal, Laval, Longueuil, North Shore and South Shore .

Maintenance: the routine that prolongs performance

To preserve seasonal performance and air quality , we recommend:

• Vacuum and rinse filters every 4 to 8 weeks depending on use;

• Cleaning the internal battery and fan (annual cycle);

• Drain inspection to prevent buildup;

• Checking the outdoor unit (wings, snow/ice clearances) before winter;

• Periodic adjustments by our certified technicians.

Pitfalls to Avoid in an Urban Condo

• Undersizing in the face of significant solar gains : it lengthens cycles and reduces comfort;

• Positioning facing a nearby obstacle (beam/bulkhead) creating recirculation ;

• Unnecessarily long refrigeration journey , which reduces efficiency;

• Forgetting the co-ownership rules for the exterior (noise, clearance, snow);

• Neglect of filters , the primary cause of reduced performance .

Why entrust your project to AirGreen?

• On-site sizing and selection of the GREE range (Airy R32, Livo R32, Clivia R32, Vireo R32… according to actual needs);

• Impeccable finishes : discreet capping, clean sealing, controlled alignments ;

• Documented commissioning with technical measurements and photos;

• Support for subsidies and responsive after-sales service ;

• Complete coverage of Greater Montreal : Montreal, Laval, Longueuil, North Shore, South Shore .

In summary

This GREE wall-mounted heat pump installation in Griffintown demonstrates that a well-sized and carefully integrated HVAC system transforms an industrial-style condo into a comfortable space year-round, without compromising on aesthetics or efficiency.
