Installation of a Gree (R32 series) wall-mounted heat pump in Rosemont–La Petite-Patrie

Four-season comfort in a Montreal apartment: precise integration despite a textured ceiling and a nearby fan

In an apartment in Rosemont–La Petite-Patrie , we installed a Gree wall-mounted heat pump (R32 series) to provide efficient heating and cooling year-round. The space presented two constraints: a low textured ceiling and the immediate proximity of a ceiling fan overhead. Our team designed a discreet and efficient layout, respecting the required clearances, while optimizing air diffusion for the living room and hallway.

Why a Gree R32 wall-mounted heat pump for this project?

Gree's new generation R-32 is distinguished by:

  • excellent seasonal efficiency (high SEER/HSPF) to reduce energy bills;

  • stable performance in cold weather thanks to inverter technology and defrosting algorithms;

  • quiet operation , ideal for apartments;

  • a reduced environmental footprint (low GWP R-32);

  • frequent eligibility for provincial subsidies when efficiency thresholds are met.

This combination meets the expectations of a Rosemont occupant: comfort , savings , and respectful integration of the interior architecture.


AirGreen Site Challenges and Solutions

1) Ceiling fan in the immediate vicinity

The fan was located a few dozen centimeters in front of the wall head . This context can generate:

  • unpredictable turbulence and backdrafts;

  • stratification if the flows oppose each other;

  • noise heard when air streams collide.

Our solutions:

  • Precise head positioning to maintain Gree recommended top and side clearances and avoid direct fan axis.

  • Fin adjustment : direction of the flow slightly forward and downward , in order to cover the living room without impacting the temperature sensor.

  • Seasonal usage advice : in summer , low to medium fan speed in counterclockwise rotation to accompany cold convection; in winter , clockwise rotation at low speed to push down hot air without disturbing the heat pump sensor.

2) Modest ceiling height and textured ceiling

Textured ceilings can trap dust and deflect airflow.
Measures taken: compliance with upper clearances , careful jointing of the support, fine leveling of the frame and checking of blowing speeds in order to avoid acoustic waves and air discharges onto the texture.

3) Discretion of refrigerant connections and condensates

To preserve the aesthetics of the apartment:

  • short route of connections behind the partition, wall outlet nearby, and minimal visible white capping ;

  • gravity drainage of condensates via dedicated wall outlet, with controlled slope and accessible service cap.


Installation process — AirGreen method

Pre-visit and sizing

We evaluate the orientation , the insulation and the volumes to be treated (living room + corridor). The configuration of the accommodation, typical of Montreal intra-muros , leads to recommending an adapted capacity (9,000 to 12,000 BTU depending on the envelope and internal contributions) to avoid oversizing - a source of short cycles and discomfort.

Fixing and crossing

  • Mounting plate fixed to uprights, laser level control.

  • Small diameter wall crossing with vapor barrier sleeve .

  • Copper connections flared to the couple, brazed and insulated over the entire length.

  • Wiring : dedicated power supply to the panel, circuit breaker according to the outdoor unit nameplate, grounding checked.

Commissioning

  • Vacuum pull to deep vacuum level, extended leak test ;

  • Opening valves and controlling superheat/subcooling ;

  • Setting the blowing curve , calibrating the probe , checking the sound levels near the ceiling fan.


Result obtained

  • Uniform cooling of the living room and circulation areas;

  • Responsive heating in mid-season and comfortable maintenance in winter;

  • Reduced noise level thanks to automatic speed and optimized air path;

  • Aesthetic integration : no visible cables except for discreet capping, respecting the style of the apartment.


Operating advice for the customer

Recommended settings

  • In summer : Cool or Dry mode depending on humidity, moderate set temperature (23–24°C) to maximize efficiency .

  • In winter : Heat mode, horizontal or slightly low fins to extend the range.

  • Avoid intensive use of Turbo mode; Auto speed with Inverter ensures the best efficiency .

HVAC Maintenance

  • Filters : monthly cleaning during periods of use;

  • Tray and drainage : checked every season to prevent odors and overflows;

  • Outdoor unit : 30–60 cm clearance around, snow removal in winter, inspection of the support;

  • Annual AirGreen visit : electrical inspection, sensors, exchangers, tightening of connections and performance measurements .


Grants and Compliance

High-efficiency R-32 wall-mounted heat pumps are often eligible for assistance programs when efficiency criteria are met. Our team supports the client in:

  • eligibility verification ;

  • preparation of documents (models, numbers, installation photos);

  • optimizing settings to achieve targeted performance.


Why entrust your project to AirGreen?

  • HVAC specialists in Greater Montreal : Montreal, Laval, Longueuil, North Shore, South Shore ;

  • Mastery of the real constraints of apartments and plexes (low ceilings, fans, limited technical passages);

  • Careful finishing : aligned capping, clean holes, silent drains;

  • Complete service : study, installation, HVAC maintenance , grant assistance.


Key technical points of this achievement

  • Type : Gree wall-mounted heat pump (R32 series)

  • Context : apartment in Rosemont–La Petite-Patrie

  • Special features : nearby ceiling fan, textured ceiling, limited height

  • Route : short wall crossing, isolated and covered connections; gravity condensates

  • Electrical : dedicated power supply and compliant protection

  • Performance : stable comfort, controlled noise level , living room + corridor coverage


Conclusion

This HVAC installation demonstrates that a restrictive indoor environment does not prevent a high-performance and discreet result from being achieved. By adapting the positioning , the adjustment of the vanes and the interaction with the ceiling fan , we ensure a homogeneous air flow , energy savings and an increased quality of life .
In Rosemont–La Petite-Patrie and throughout Greater Montreal , AirGreen delivers Gree R32 solutions designed for the local climate and the architectural realities of our buildings.
