In a residential area like Fabreville , where single-family homes and finished or unfinished basements are commonplace, the reliability of the HVAC system is essential. At AirGreen , we regularly service, maintain, and diagnose Tosot wall-mounted heat pumps , particularly in situations similar to the one shown in the photo: a wall-mounted installation in a space under construction, with exposed framing and easy technical access.
A Tosot wall-mounted heat pump well-suited to Laval residential use
The visible unit is clearly a wall-mounted heat pump (mini-split) , installed high on a load-bearing wall. Its size, motorized louvers, and compact indoor unit are typical of Tosot wall-mounted systems , which are very popular in Quebec for their excellent performance-to-price ratio and their ability to efficiently manage both heating and cooling.
In this type of configuration, we often find a Tosot model from the Lomo R32 range or equivalent: a modern wall-mounted heat pump, designed to offer good energy efficiency , quiet operation and a response adapted to the climatic variations of Greater Montreal .
Service context observed on the ground in Fabreville
In Fabreville, several properties incorporate wall-mounted heat pumps in strategic areas: basements, multigenerational living spaces, family rooms, or home offices. The context visible in the photo suggests:
-
Installation in a space undergoing renovation or finishing
-
Interior wall reinforced with wood paneling
-
Refrigerant lines and wiring run from the top
-
Direct access to the structure, ideal for complete inspection and in-depth maintenance
This type of environment is perfect for performing rigorous HVAC service , without access constraints.
Our complete Tosot heat pump service
At AirGreen , Tosot wall-mounted heat pump service is never limited to a simple quick cleaning. We always proceed with a structured and preventative approach.
Detailed technical diagnosis
We systematically check:
-
Pressures and temperatures of the refrigeration circuit
-
Tosot sensors are functioning correctly
-
Compressor and fan responsiveness
-
Communication between the indoor and outdoor units
This diagnostic allows anomalies to be detected before they affect comfort or electricity consumption .
Deep cleaning of the wall unit
In homes in Fabreville, renovation dust, wood particles, and fine debris are common. We perform:
-
Complete filter cleaning
-
Disinfection of the evaporator
-
Tangential fan cleaning
-
Checking and rinsing the condensation drain
Proper maintenance improves indoor air quality and extends the lifespan of the Tosot heat pump.
Adjustments and optimization
We also:
-
Calibration of Tosot parameters according to actual usage
-
Checking the orientation of the motorized shutter
-
Optimizing heating mode for Quebec winters
-
Validation of defrost cycles
These adjustments are essential to ensure stable performance in extreme cold .
The importance of preventative maintenance in Laval
In Laval, and particularly in Fabreville, seasonal temperature fluctuations put heat pumps under considerable strain. A poorly maintained Tosot heat pump can:
-
Lose up to 25% of yield
-
Unnecessarily consuming more electricity
-
Generate noise or vibrations
-
To exhibit odors or poor drainage
An annual service by AirGreen helps to avoid these problems and ensures consistent comfort all year round .
