In a typical residential apartment in Villeray–Saint-Michel–Parc-Extension , we recently performed a complete service on an LG wall-mounted heat pump , installed high above an interior passageway. This type of configuration is common in Montreal apartments with standard ceilings, where optimizing space and ensuring even air distribution are essential for everyday comfort.
At AirGreen , we provide service, maintenance and diagnostics for LG wall-mounted heat pumps throughout the Island of Montreal, with a rigorous approach adapted to the Quebec climate and the realities of existing urban buildings.
LG wall-mounted heat pump: a discreet and efficient system
The system observed is an LG wall-mounted heat pump (mini-split) , a solution widely used in Montreal homes for ductless heating and cooling. The compact and stylish indoor unit is designed to provide quiet comfort while blending seamlessly into the décor.
In this particular case, the exact model was not legible, but the unit corresponds to a recent generation LG wall-mounted heat pump , equipped with a multi-speed fan, a high-efficiency heat exchanger and a motorized flap ensuring good distribution of hot or cooled air.
Key service details observed on site
During our visit to Villeray, several visual and technical elements guided our intervention:
-
Wall-mounted unit installed high up , promoting optimal air distribution
-
Visible accumulation of dust at the suction grille
-
Active operation , but with a slightly reduced airflow
-
No abnormal noises , indicating a compressor and fan in good condition.
-
Unobstructed access , facilitating thorough maintenance without excessive dismantling
These indicators suggested that comprehensive preventative maintenance was required to restore performance and avoid excessive power consumption.
Our AirGreen intervention: a complete and methodical service
We performed an LG wall-mounted heat pump service in accordance with HVAC best practices, taking into account the specific constraints of urban housing in Montreal.
Key steps in the service provided
-
Deep cleaning of washable filters
-
Dusting and disinfection of the internal evaporator
-
Check the condensation drain to prevent leaks
-
Airflow control and motorized flaps
-
Visual inspection of electrical connections

This intervention not only improves indoor air quality, but also extends the lifespan of the LG heat pump , while maintaining its optimal energy efficiency.
Why maintenance is crucial in Montreal
In areas like Villeray–Saint-Michel–Parc-Extension , wall-mounted heat pumps are used year-round: air conditioning in the summer, supplemental or primary heating during the colder months. Without regular maintenance:
-
Performance gradually decreases
-
Electricity costs are increasing
-
The risk of breakdowns in the middle of winter increases.
-
Indoor air quality is deteriorating
An annual or biannual service is highly recommended for LG systems, especially in older buildings where ambient dust is more prevalent.
