A galvanized bracket mount that protects the unit, maximizes airflow and blends seamlessly into a brick facade
At AirGreen , we have just completed the HVAC installation of a TOSOT wall-mounted heat pump on the side facade of a typical duplex in Rosemont–La Petite-Patrie . In this green alley, the red brick imposes its style: we opted for a raised wall support , anti-vibration pads and discreet capping to combine performance , durability and aesthetics . The owner's objective was clear: reliable supplemental heating in winter, precise air conditioning in summer, and a clean, accessible and quiet installation.
Context and technical choices
The house benefits from a narrow side driveway, typical of Montreal plexes. This context influences several decisions:
-
favor a condenser on consoles (and not on the ground) to free the passage , protect the unit from snow accumulations and avoid shocks;
-
maintain front and top clearances in accordance with the manufacturer's rules to ensure airflow and quality of defrost cycles;
-
reduce the length of refrigeration connections by positioning the outdoor unit close to the drilling, which improves efficiency and limits the risk of premature wear.
We recommended a TOSOT – inverter range for its speed modulator which continuously adapts the power to the actual need, reducing on/off cycles , power consumption and noise .
Outdoor installation: robustness and precision
The condenser is mounted on a galvanized wall bracket sized for load and wind resistance. Blue anti-vibration pads are installed under the unit's base plate, which cut off the transmission of waves to the masonry. Anchors are made in the mortar joints whenever possible, to preserve the brickwork ; precise layout of the anchor points ensures perfect alignment of the frame.
The external trunking protects the insulated copper lines , the power cable and the condensation drain . The bend radii at the casing outlet are generous to avoid mechanical stress. In the immediate vicinity, an external disconnect switch facilitates maintenance and service interventions according to the Code requirements.
Benefits of this configuration:
-
unit outside splash zone and above snow level;
-
easy inspection of coils and fan;
-
optimized air circulation in the narrow alley;
-
reduction of noise pollution transmitted indoors.
Route of connections and sealing of the envelope
The drilling is carried out with an outward slope to promote the gravity flow of the drain. We provide:
-
brazing under nitrogen of dehydrated copper connections;
-
deep vacuum and leak test before opening the valves;
-
high density insulation sleeved up to the casing to limit heat loss and condensation ;
-
vapor barrier and sealant around the drilling to maintain the wall's watertightness .
The power cable runs through a waterproof enclosure, with tight grommets and properly oriented drip trays . The unit's data label, left accessible, facilitates future HVAC maintenance operations.
The TOSOT wall-mounted heat pump in action
The TOSOT inverter range is designed to offer:
-
efficient heating at low ambient temperature thanks to compressor modulation;
-
stable air conditioning with minimal temperature variations in the room;
-
a contained noise level on the condenser and interior head side;
-
washable filters and simplified maintenance .
Depending on the surface area and insulation, we size the appliance between 9,000 and 24,000 BTU to respect the actual thermal load of the home. This approach avoids oversizing , which is a source of short cycles, discomfort and loss of efficiency.
Commissioning: checks and adjustments
When switching on, our team proceeds to:
-
verification of intensities and pressures ;
-
the measurement of temperature deltas in cooling and heating;
-
adjusting the ventilation speeds and direction of the indoor head flaps ;
-
validation of defrosting and clearances around the unit;
-
customer training : filters, eco modes, programming, good winter practices.
The result: remarkable temperature stability in the living areas, rapid response when the setpoint changes and very low ambient noise in the alley.
What we have taken care of in addition (execution details)
-
Drain management : continuous slope towards the outside, protection against frost and termination invisible from the alley.
-
Mechanical protection : the trunking route is kept as short as possible, rounded corners and spaced fixings to prevent buckling.
-
Service compatibility : clearly identified disconnect switch , clear access to the housing and nameplate.
-
Aesthetics : choice of a sober-colored capping to match the red brick, aligned finishing screws, cleaning of the site.
Best practices and pitfalls to avoid (AirGreen feedback)
-
Always respect the clearances around the condenser: an insufficient air volume degrades the efficiency and complicates defrosting .
-
Raise and separate the unit from the passage areas: this protects the equipment and reduces vibration transmission .
-
Limit the length of the connections and the number of bends : a short line is synonymous with efficiency .
-
Ensure the slope of the drain and avoid water traps ; protect against freezing.
-
Plan maintenance : accessible filters, disconnect switch within reach, actual clearances (not just “on plan”).
HVAC Maintenance: The Simple Plan That Extends Unit Life
We recommend:
-
cleaning the filters every 4 to 8 weeks during periods of use;
-
annual inspection : pressures, temperatures, electrical tightening, condition of insulation and capping ;
-
clearing plants around the condenser and dusting the fins;
-
Check the drain when the snow melts and at the start of summer.
Regular maintenance maintains performance coefficients and avoids surprises during the height of heat waves or January cold.
