Careful integration into a brick house in Laval
At AirGreen , we recently completed the relocation of a Daikin wall-mounted heat pump in the Chomedey area of Laval . This project perfectly illustrates our approach: combining energy performance, careful aesthetics and compliance with the strictest HVAC standards for Greater Montreal.
The client, who owns a brick house, had bought this Daikin wall-mounted heat pump a while ago and wanted it moved. Our team took the unit down and put it back up at the new location.
The particularities of the installation
Positioning the outdoor condenser
The Daikin condenser was reinstalled on an outdoor slab, in close proximity to the electrical panel. This choice minimizes the length of electrical cables and conduits , thus reducing losses and optimizing overall efficiency.
The client was also keen to preserve the aesthetics of its brick facade. We therefore used brown capping to match the color of the masonry, ensuring a harmonious visual integration .
Refrigerant duct management
The layout of the house required a significant vertical rise along the brick wall , up to the second floor. This technical constraint was overcome thanks to a solid and discreet fixing, with carefully aligned capping sections.
Gravity drainage of condensates was preferred, which avoids the addition of a lifting pump and ensures minimal long-term maintenance.
Residential context
The project is taking place in a typical Laval environment: brick terraced houses, dense vegetation, and limited space between the properties. We had to deal with the proximity of a fence and a cedar tree, while ensuring we respected the clearances recommended by the manufacturer to ensure adequate ventilation of the condenser.
A process controlled from start to finish
Initial assessment
During the initial visit, our team carefully analyzed the optimal location for the outdoor unit and the ductwork. The owner wanted to limit the visual impact, which guided our decision to perfectly align the hoods with the architectural elements of the facade.
Installation and testing
Once the system was reinstalled, we performed pressure and commissioning tests following the manufacturer's recommendations and HVAC industry standards. These steps ensure the durability of the installation and optimized energy efficiency.
Result
The final result is visually discreet, technically efficient and perfectly integrated into the home . The client now benefits from four-season comfort.

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
