In this urban condo located in the heart of Ville-Marie , our AirGreen team performed a complete service on a Zephyr wall-mounted heat pump . The context is typical of downtown Montreal: limited space, intensive use of the system, and the crucial importance of indoor air quality for both comfort and energy efficiency.
A Zephyr wall-mounted heat pump adapted to urban life
The system observed is a Zephyr brand wall-mounted heat pump (mini-split) , installed high on an interior wall. This type of unit is particularly popular in Ville-Marie condos due to its compact size, quiet operation, and ability to provide both heating in winter and cooling in summer.
Since the exact model is not visible in the image, we are referring to a new generation Zephyr wall-mounted heat pump , consistent with the ranges currently used in Montreal residential settings: high efficiency, modern electronics and precise temperature control.

Why maintenance is crucial in the heart of the city
In Ville-Marie, wall-mounted heat pumps are subject to specific conditions: urban dust, heavy traffic, and almost continuous use year-round. Without regular maintenance, even a high-performance Zephyr wall-mounted heat pump can:
-
lose energy efficiency
-
consume more electricity
-
to diffuse lower quality air
-
see its lifespan reduced
Preventive maintenance not only ensures immediate comfort, but also protects the long-term investment .
