Installation of a Gree wall-mounted heat pump in Rosemont–La Petite-Patrie

In this typical Rosemont–La Petite-Patrie apartment in the heart of Montreal, we installed a Gree wall-mounted heat pump to offer our clients four-season comfort while reducing their electricity bill.

The context: a home heated by electric baseboard heaters

The apartment is heated primarily by electric baseboard heaters, controlled by a wall thermostat visible beneath the unit. Like many apartments in the area, wall space is limited: doors, hallways, and other openings restrict installation options.

The client's objective was clear:

• to effectively air-condition the living room and the hallway leading to the other rooms;

• add efficient heating for the mid-season and a good part of the winter;

• maintain a clean aesthetic, without visible ducts or conduits inside.

The Gree wall-mounted heat pump emerged as an ideal solution: compact, quiet and capable of heating even in cold weather.

Choosing the Gree wall-mounted heat pump

We opted for a new generation Gree wall-mounted heat pump , single-zone type, with a capacity of around 12,000 BTU, perfectly suited to a medium-sized open area.

Some key features of this Gree range:

• operation in heating mode down to very low outside temperatures;

• Inverter technology to precisely follow demand without overconsumption;

• modern refrigerant with low environmental impact;

• very low noise level, both inside and outside.

The discreet display on the right-hand side (setpoint temperature) allows the customer to check the setting at a glance without cluttering the room's design.

A wall-mounted installation designed for comfort

The indoor unit was installed high up, centered on the wall between a bedroom door and a hallway. This position is not accidental:

• it allows the blown air to spread widely throughout the main room;

• the airflow can be directed towards the corridor in order to send coolness or heat to other rooms;

• Avoid blowing directly onto the sofa or dining table, for comfort without drafts.

Motorized louvers direct airflow downwards and forwards, ensuring good temperature stratification in the room. Inside, there are no visible pipes: the refrigerant lines and condensate drain run directly behind the unit, through the exterior wall. The result: a completely clean and minimalist wall .

The original thermostat for the electric baseboard heaters is retained at the bottom of the wall: the baseboard heaters remain available as a supplement or backup, but it is now the Gree that provides most of the heating and air conditioning.

Technical details of the installation

As with all our installations, we have applied best HVAC practices:

• Dedicated power supply from the panel, with appropriate circuit breaker and external circuit breaker near the compressor.

• Passage of refrigerant lines through the wall to the outdoor unit, with discreet casing on the outside to protect the pipes and wiring.

• Nitro leak test followed by deep vacuuming to guarantee the absence of moisture and air in the refrigeration circuit.

• Drain slope settings to ensure condensate drainage in air conditioning mode, without risk of dripping or backflow.

• Complete commissioning : checking pressures, blowing temperature, remote control calibration, explaining modes to the customer (heating, air conditioning, dehumidification, ventilation, eco mode, etc.).

The outdoor unit, installed on anti-vibration supports outside the dwelling, was positioned to facilitate maintenance and snow removal while limiting the transmission of noise into the interior.

Comfort, savings and silence in everyday life

From the very first days, the occupants noticed:

• a noticeable decrease in humidity and heat during summer heat waves;

• a gentle and constant warmth in autumn and in the heart of winter, without the sudden fluctuations like with baseboards;

• a reduction in electricity consumption , since the Gree heat pump recovers energy from outside rather than producing heat solely by electrical resistance;

• very quiet operation: the fan at low speed is barely perceptible in the room.

Thanks to the remote control and the display on the front panel, setting it up is simple: a set temperature, a mode, and the Gree wall-mounted heat pump takes care of the rest.
