At AirGreen , we regularly work in the Saint-Laurent area, a residential neighborhood in Montreal characterized by its brick buildings, duplexes, and well-established single-family homes. The provided photo perfectly illustrates this type of environment: brick facade, exterior wall-mounted installation on a metal bracket, unobstructed side access—a typical setting for a residential wall-mounted heat pump .
In this particular case, it's a Tosot wall-mounted heat pump , a brand renowned for its reliability, performance in northern climates, and excellent value. Our intervention involved a complete service aimed at ensuring the proper functioning of the unit, optimizing its efficiency, and preventing breakdowns, which are particularly important in the climatic conditions of Greater Montreal.
Tosot wall-mounted heat pump: a system adapted to Saint-Laurent residences
The Tosot wall-mounted heat pump installed here is a compact, next-generation unit, perfectly suited to the needs of Montreal homes. While the exact model is not clearly identifiable visually, the configuration shown is that of a modern Tosot inverter wall-mounted heat pump , designed to provide:
-
Efficient heating during the Quebec winter
-
Stable and quiet air conditioning in summer
-
Optimized energy consumption

Reliable operation even during large temperature variations
This type of system is particularly popular in Saint-Laurent, where many buildings do not have central conduit networks, making the wall-mounted solution ideal.
Visual analysis and service details observed on site
