Stable comfort, discreet finish and short run: an installation designed for apartments and plexes in Rosemont
Project background
At AirGreen , we support many apartment and plex owners in Montreal who want to improve their summer comfort and benefit from efficient heating support in the spring and fall. In this Rosemont–La Petite-Patrie home, our client was looking for a compact , quiet , and economical solution that would perfectly integrate with the interior finishes. We proposed a Gree wall-mounted heat pump from the Livo R32 range , known for its balance between efficiency, aesthetic simplicity, and reliability.
The living space features a perfectly smooth, neutral-toned wall with a standard ceiling height: ideal conditions for installing the headboard high up, ensuring efficient airflow and maintaining a clean visual line.
Why the Gree Livo R32 range for this type of habitat
Energy efficiency and Montreal's climate
The Livo R32 boasts advantageous SEER/HSPF ratios thanks to R-32 refrigerant, which is more efficient than R-410A. It operates stably on cool spring and fall nights, making it a powerful supplemental heater for Montreal, Laval, Longueuil, North Shore and South Shore . In summer, its dehumidification control reduces discomfort without increasing the number of cycles.
Discretion and acoustic comfort
The smooth front, discreet digital display , and motorized shutters give the wall-mounted unit a minimal presence in the room. The low-speed mode keeps noise levels very low in the evening, while maintaining sufficient air circulation.
Maintenance facilitating sustainability
Washable filters remove in seconds. The evaporator design simplifies preventative disinfection and condensate drain checks, two actions that maintain long-term performance and support healthy air quality .
Sizing and capacity selection
For standard living spaces in Rosemont–La Petite-Patrie plexes (20–35 m², standard ceiling height), the target capacity is typically between 9,000 and 15,000 BTU/h depending on:
-
insulation and type of windows;
-
orientation (solar gains in the afternoon);
-
the continuity of spaces (living room open to dining room);
-
usage (daytime presence, teleworking).
We favor precise sizing in order to avoid short cycles, guarantee temperature stability and limit consumption.
Integration and route of connections
Inner head positioning
The Gree Livo R32 head is fixed high on the wall , a few centimeters from the ceiling, so that the air jet follows the ceiling before gently descending. This placement improves temperature uniformity and avoids direct drafts in living areas.
Drilling and evacuation of condensates
A rear drilling was carried out with a slight gravity slope towards the outside (2–3%): the condensate evacuation is carried out naturally, without a pump. We sleeve the passage and ensure airtightness on the inside and outside to prevent any infiltration and maintain the performance of the envelope.
Refrigeration lines and external capping
The insulated copper lines follow a short route to the outdoor condenser, protected in a UV-resistant trunking that matches the facade. This choice guarantees a clean finish, easy maintenance and minimal pressure losses .
Condenser installation
In the backyard, the condenser is placed either on an anti-vibration slab or on wall brackets depending on the configuration. We respect the recommended clearances for good air circulation, provide winter protection (height from snow) and position the unit away from passages to secure access.
AirGreen Quality Procedure
-
Turntable leveling and laser trim control to ensure flow.
-
Flare fittings made with calibrated flares, torques to the dynamometer .
-
Nitrogen pressure test and deep vacuum (< 300 microns) with stabilization to certify watertightness.
-
Vibration management : pads under condenser, spacers and suitable tightening.
-
Finish : trunking, UV neutral silicone seals, cleanliness plugs.
-
Commissioning : checking supply/return temperatures, intensities, sweep parameters and speeds .
Recommended usage settings
-
Cooling mode during summer days with auto speed ; switch to low speed in the evening to reduce noise.
-
Wide horizontal sweep to mix the volume under the ceiling and slight vertical angle to avoid direct air on the occupants.
-
Reasonable instruction : rather than forcing a very low temperature, take advantage of the dehumidification mode to gain comfort.
-
Time programming or control via Wi-Fi (depending on the card installed) to adapt occupancy periods.
Grants and energy compliance
New generation wall-mounted heat pumps with R-32 and recognized performance (e.g. Energy Star , cold climate) are eligible for certain assistance programs, subject to the criteria in force. We support each file: certificates , technical sheets and advice to optimize the investment in Greater Montreal ( Montreal, Laval, Longueuil, North Shore, South Shore ).
HVAC Maintenance: Simple and Effective Schedule
-
Clean filters every 4 to 8 weeks during periods of heavy use.
-
Annual inspection by our technicians: drain, electrical connections, checking supply/return temperatures, condition of fins.
-
Gentle cleaning of the outdoor condenser (debris, lint, pollen) and light straightening of the fins if necessary.
-
Check capping and seals after winter to prevent any infiltration.
Regular HVAC maintenance ensures stable performance , increased longevity and lasting quiet operation .
Specific challenges of this project and solutions
Visual optimization in a clean room
The smooth wall and neutral palette required minimalist integration . We chose a direct rear passage to eliminate any interior cable ducts and preserve the aesthetics. The front display remains visible but discreet, useful for reading the instructions without adding a wall-mounted remote control.
Short, protected outdoor course
The rear frame provides quick access to the exterior. We have reduced the length of the connections to limit losses and facilitate maintenance. The condenser benefits from a clearance greater than the average snow depth and is positioned away from ice fall zones.
Results: perceived comfort and controlled consumption
From the moment it is switched on, the uniform blowing ensures a rapid drop in the perceived temperature. In the off-season, the Livo R32 provides reliable support: electric baseboards are used later, which results in savings and appreciable thermal stability . The contained noise level enhances quality of life, particularly for teleworking .
Best practices for housing in Rosemont–La Petite-Patrie
-
Avoid oversizing : prioritize the right capacity for regular cycles and maximum efficiency.
-
Encourage gravity drainage of condensates; only use a pump as a last resort.
-
Protect the condenser : avoid niches, respect clearances and provide an awning if exposed to snowfall.
-
Schedule maintenance before heat waves and winter to maintain peak performance.
-
Optimize interior circulation : open adjacent doors during hot weather to distribute the coolness.
