In a residential unit in Villeray–Saint-Michel–Parc-Extension , we provided complete service for a Haxxair wall-mounted heat pump installed high up, near a window with blinds and above a kitchen area. This type of location is common in Montreal: convenient for air distribution, but demanding in terms of maintenance, as cooking dust, ambient humidity, and temperature fluctuations accelerate the fouling of internal components.
Our goal at AirGreen is simple: to restore the Haxxair device to its best performance level, reduce the risk of breakdowns and ensure stable comfort, both in air conditioning in the summer and in heating during the Quebec winter.
A Haxxair wall-mounted heat pump: why regular service is essential
A wall-mounted heat pump (mini-split) operates efficiently when air and heat exchange are unobstructed. As soon as the filters, turbine, or evaporator become clogged, the following problems are quickly observed:
-
a decrease in airflow (a feeling that “it’s blowing less”)
-
slower and less uniform air conditioning
-
an increase in noise (unbalanced turbine, friction, vibration)
-
odors (biofilm, residual moisture, dust)
-
an increased risk of droplets or runoff (partially blocked drain)
In a room like a kitchen (even an open-plan one), these effects can appear sooner than elsewhere. Hence the importance of professional maintenance in addition to basic cleaning.
What we observed on site (visual clues and actual context)
The photo clearly shows a wall-mounted indoor unit installed at a height, with:
-
direct proximity to a window with blinds (temperature variations, dust, local air circulation)
-
installation near a kitchen area (fine particles, humidity, suspended micro-greases)
-
Access at height (requires a clean, safe and methodical approach to avoid any soiling)
These details guide our way of working: surface protection, drainage control, fin orientation verification and air diffusion optimization to avoid “dead” zones.
Our AirGreen service on this Haxxair wall-mounted heat pump
1) Performance diagnosis and basic checks
Before cleaning, we check the overall condition and behavior of the unit:
-
reading the modes (heating / air conditioning / dehumidification / ventilation)
-
checking the response of the remote control and the sensors
-
airflow and operating noise control
-
Visual inspection of panels, joints and clips (to avoid vibrations and creaking)
2) Cleaning and restoration of the indoor unit
On a Haxxair wall-mounted heat pump , performance depends heavily on the cleanliness of the heat exchanger and the turbine. Our service typically includes:
-
cleaning the filters (and checking their condition)
-
dust removal/sanitization of the suction area
-
Thorough cleaning of the evaporator (fins) using an appropriate method
-
cleaning the turbine (where dust often accumulates)
-
wiping and cleaning of accessible internal plastics and ducts
Objective: to restore stable breathing, reduce odors, and improve heat transfer capacity.
3) Drainage and condensation management
One of the critical points in residential plumbing is drainage. We check:
-
the normal flow of condensation water
-
the absence of partial blockage (dust, deposits, biofilm)
-
the general condition of the pathway (to prevent drips and overflows)
This is an often overlooked element, yet very common during service calls.
4) Electrical controls and safety
Without unnecessarily complicating things, we validate what matters:
-
Accessible connections and general status
-
consistency of cycles (start-up, shutdown, ventilation)
-
signs of overheating, electrical odor, or unstable component
5) Adjustments and usage recommendations
Once the device is clean and stable, we optimize its use:
-
Recommendation regarding the setpoint temperature (avoid excessively short cycles)
-
Advice on "Dry" mode vs. air conditioning, depending on humidity
-
frequency of filter cleaning, especially near a kitchen
-
Good practices for maintaining comfortable airflow (fin orientation, auto mode, etc.)
Expected result: comfort, efficiency and peace of mind
After a complete service on a Haxxair wall-mounted heat pump , the most common gains are:
-
cleaner air and reduced odors
-
a more direct and uniform airflow
-
quieter operation
-
improved stability in heating/cooling
-
less risk of leaks or avoidable breakdowns
And above all: a machine that works less hard for the same comfort, which is exactly what we want in Montreal, where the seasons impose long periods of use.
