Relocating a Daikin wall-mounted heat pump in a Rosemont–La Petite-Patrie plex

A careful relocation that combines comfort, sobriety and performance

At AirGreen , we carry out HVAC installations tailored to everyday Montreal living. This project highlights the relocation of a Daikin wall-mounted heat pump in a bright apartment in Rosemont–La Petite-Patrie , where the client's primary requirement was clear: improve four-season comfort without encroaching on the minimalist aesthetic of the space.

The owner had bought this Daikin wall-mounted heat pump some time ago and wanted it moved. We removed the existing unit and reinstalled it at the new location.

Context and objectives of the project

The apartment, located on the top floor of a typical Rosemont apartment building, benefits from good thermal inertia but quickly became hot in the summer and too cool in the spring and fall.

An exemplary HVAC installation, thought out in detail

Study of implantation and air circulation

Before any drilling, we validate:

• the installation height (close to the ceiling, while respecting the clearance required for air suction);

• the blowing axis towards the living room in order to cover the space evenly without creating annoying air currents;

• the proximity of an exterior wall to limit the length of refrigeration connections and facilitate the evacuation of condensate.

The chosen positioning allows the motorized shutter to direct the flow in width and depth, for rapid and homogeneous air mixing.

Drilling and fixing on masonry wall

Installing a wall head on a brick/concrete support requires suitable anchors:

• Laser tracing, leveling to the nearest millimeter;

• Use of expansion anchors and anti-corrosion screws;

• Exact-diameter through-hole for refrigeration lines, communication cable, and condensate drain—all sloped slightly outward for reliable gravity drainage .

This approach avoids vibrations, guarantees the longevity of the fixings and preserves the integrity of the wall.

Refrigeration lines, power supply and finishing

• Route shortcuts : “back-to-back” exit to the outside, minimizing the length of piping;

• Brazing and flaring to standards, with nitrogen leak testing and deep vacuum to protect the compressor;

• Communication cable sized to actual length, routed neatly;

• Discreet exterior capping , matching the color of the facade;

• Addition of an external disconnect switch for safe maintenance of the condenser;

• Check the drip-loop and the slope of the drain to avoid any backflow.

The result: understated finishes that are visually invisible and easy to maintain.

Commissioning and checks

• Pressure and temperature control using digital tools;

• Calibration of airflow and louver angles according to room configuration;

• Tests in cooling and heating modes;

• Validation of noise level and absence of vibrations.

An installation report is given to the customer, with recommendations for use and maintenance.

Construction site challenges and AirGreen solutions

1) Masonry support and cleanliness of the drilling

Drilling a hard wall into a finished housing requires precision and dust control . We use diamond core bits , HEPA vacuums , and localized protection . The interior is left clean, with no chips around the line crossing.

2) Clearances and ceiling lighting

The chosen wall sits beneath a clean white ceiling. We adhered to the manufacturer's recommended overhead and side clearances to optimize suction and avoid any interaction with lighting, which could cause turbulence or harsh shadows.

3) Aesthetics and visual continuity

The client wanted to keep things simple : the exterior pipe cover was chosen in a light shade , and the internal connections are invisible. The unit blends into the room's white palette , while remaining accessible for maintenance.

AirGreen Best Practices for a Sustainable Wall-Mounted Heat Pump

Responsible sizing

An oversized system shortens its cycles, loses efficiency and prematurely wears out its compressor. We size according to:

• of the actual air-conditioned surface ;

• solar exposure and insulation quality ;

• Montreal's specific winter heating needs .

Minimal but regular maintenance

• Filters : monthly dusting during periods of intensive use;

• Exchanger : annual gentle cleaning to maintain efficiency;

• Condensate : check the slope and flow in spring;

• Outdoor unit : clear grilles, snow guard if exposed to snowdrifts.

We offer HVAC maintenance plans tailored to residences in Montreal, Laval, Longueuil, North Shore and South Shore .

Wise use

• In summer, favor a stable setting rather than extreme back and forth movements;

• In winter, keep interior doors open to promote diffusion;

• Set realistic setpoints (e.g. 22–23°C depending on preference and humidity).
