A Symphony of Efficiency and Stealth: Unpacking the Montréal-Est Installation
Invisible Powerhouse: The Under-Deck Marvel
In the serene and bustling area of Montréal-Est, our team at AirGreen recently completed an installation that is nothing short of a masterpiece. The client required a powerful yet silent machine, and the Haxxair T2D Wall-Mounted Heat Pump was the chosen knight in shining armor for this quest.
Why Haxxair T2D?
- Silent Operation: With sound pressure levels as low as 34 dB(A) indoors, the T2D is a whisper in the night, ensuring uninterrupted tranquility for the household.
- Powerful Performance: Boasting an 18,000 BTU cooling capacity, it stands vigilant against the summer heat, providing a cool and comfortable living space.
- Winter Warrior: Its ability to provide heating at temperatures plummeting to -25°C makes it a reliable companion during the harsh Canadian winters.
- Energy Efficiency: With a stellar 23.2 SEER efficiency rating and Energy Star® certification, the T2D is a guardian of both comfort and sustainability.
Crafting Invisible Comfort
Our client’s living room, located on the main floor, was in dire need of a robust 18,000 BTU heat pump. However, the challenge was the location of the electrical panel, discreetly placed in the basement. The plot thickened with the client’s wish for an installation that is neither seen nor heard, yet felt in its comforting embrace.
Under the Deck: A Tale of Precision and Innovation
The solution was ingenious and elegant. The perfect spot under the backyard deck was chosen for the compressor installation. This choice was not only aesthetically pleasing but also economically sound:
- Space Conservation: Nestled under the deck, the machine neither intrudes upon the visual landscape nor consumes precious backyard space.
- Proximity to Power: Its location near the electrical panel minimizes the use of electrical wiring, reducing installation costs.
- Short Piping Distance: With the living room just above, the need for extensive piping was eliminated, further driving down the cost.
A Warranty Worth Its Weight in Gold
The Haxxair T2D comes with an unparalleled 10-year warranty on the compressor, parts, and labor. This comprehensive coverage is a testament to the product’s durability and the brand’s confidence in its machinery.
The Silent Guardian
Positioned adjacent to a window, the unit had to be as silent as the falling snow. The T2D, with its ultra-silent mode, not only met but exceeded expectations. Its presence is felt, not heard, creating an atmosphere of serene comfort.
Conclusion: A Tale of Success
This installation story is one of triumph over space constraints and client requirements. The under-deck installation of the Haxxair T2D in Montréal-Est is a symphony of power, silence, and efficiency, conducted masterfully by the experienced hands at AirGreen. With each project, we not only deliver temperature comfort but also peace of mind, ensuring that our clients are enveloped in an ambiance of ease and reliability.
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.
