Installation of a wall-mounted LG heat pump in Montreal North

An optimized HVAC installation for a duplex in Quebec winter

At AirGreen , we recently installed an LG wall-mounted heat pump in a duplex in the Montreal North area. In this residential neighborhood characterized by its brick buildings and typical metal balconies, our clients wanted a four-season heating and cooling solution, adapted to harsh winters and increasingly hot summers.

The request was clear: install a high-performance unit that could reduce dependence on traditional electric heating while ensuring constant comfort.

Choosing an LG wall-mounted heat pump

LG was a strategic choice for this project. Its wall-mounted heat pumps are recognized for:

• Their inverter technology , guaranteeing intelligent power modulation.

• Stable performance down to -25°C , ideal for Montreal's climate.

• A compact and modern design , perfectly suited to urban spaces.

• High energy efficiency , contributing to savings on the electricity bill.

The model chosen by the customer, with a capacity of 12,000 BTU , is designed to meet the needs of an area of ​​approximately 450 to 500 sq. ft., the equivalent of a full floor of the duplex.

Key steps of installation

Our technicians carried out a custom installation, despite winter conditions and a restricted environment on the rear balcony.

1. External compressor mounting

   • The LG outdoor unit was installed on sturdy wall brackets , fixed directly into the brick.

   • This choice frees up floor space on the balcony and avoids any obstruction by accumulated snow.

2. Passage of refrigerant pipes

   • The pipes were laid discreetly, with exterior capping matching the brick , ensuring an aesthetic finish and protection against the elements.

   • The total length of the links has been reduced to a minimum, optimizing the efficiency of the system.

3. Condensation drain management

   • Due to the winter season, special attention was paid to the drain. The system was configured for gravity flow , avoiding the risk of freezing and reducing the need for maintenance.

4. Electrical connection

   • A direct connection to the electrical panel was made with a dedicated circuit breaker, in accordance with RBQ standards.

   • The wiring has been secured to withstand outdoor conditions (rain, snow, thermal variations).

5. Commissioning and testing

   • After a leak test and a vacuum, the device was put into operation.

   • The performance was checked in heating mode , confirming a homogeneous diffusion of hot air throughout the floor.

The challenges encountered

This installation presented two main challenges:

• Limited space on the rear balcony : we opted for a high wall installation to free up circulation and secure the device.

• Winter conditions : Working in cold weather requires rigorous preparation. Our technicians used specially designed equipment to ensure precise work despite the snow and ice.

Results and benefits for the client

The customer now benefits from four-season comfort thanks to:

• A stable and pleasant temperature in winter and summer .

• Reduced electricity bills , thanks to the energy efficiency of the LG heat pump.

• A discreet and aesthetic installation , perfectly integrated into the brick facade of the duplex.
