The Challenge of Invisible Wires and Aesthetics
In the heart of Île-Bizard–Sainte-Geneviève, we at AirGreen faced one of our most intriguing challenges yet. Our client had a clear vision: a state-of-the-art Tosot LomoPlus UltraHeat Wall-Mounted Heat Pump, but with a twist. They wanted a seamless integration into their living space, with not a single wire or pipe in sight. A challenge, yes, but one we were eager to tackle.
The Art of Concealment
The task was clear: install the head unit in the living room's center while ensuring the compressor was discreetly placed at the house's back. This meant navigating through two rooms, walls, and ceilings, all while ensuring a clean finish. Our dedicated team brainstormed, planned, and executed a strategy that would make even the most intricate of art heists seem straightforward.
The Machine: Tosot LomoPlus UltraHeat
- Cooling Capacity: 12,000 BTU, ensuring optimal comfort during those sweltering summer days.
- Heating Capacity: Remarkable performance even at -30°C, making it a true winter warrior.
- Efficiency: Boasting a 30.5 SEER, it's not just powerful but also energy efficient.
- Sound: With an exterior sound pressure level of 53.0 dB(A) and an interior range of 22 to 49 dB(A), it's whisper-quiet.
- Connectivity: WiFi included, allowing for smart control and convenience.
- Warranty: A solid 10-year warranty on the compressor, parts, and labor. Peace of mind guaranteed.
- Eco-friendly: Uses R-410A gas, ensuring a reduced carbon footprint.
Grants and Savings
This particular model is not just a powerhouse in performance but also in savings. It's eligible for a Federal Grant of up to $5,000 and a Provincial Grant of $405. Investing in quality and efficiency has its rewards!
The Outcome
After meticulous planning and execution, the result was nothing short of perfection. The head unit, with its sleek dimensions of 39.2 x 8.8 x 11.8, blended seamlessly into the living room, while the exterior unit, measuring 35.3 x 14.8 x 23.4, found its discreet spot at the back of the house.
Our client's reaction? Absolute delight. Not only were they thrilled with the aesthetic outcome, but they were also ecstatic about their new, ultra-efficient, and silent heat pump. And the cherry on top? Their recommendation led us to another installation just three days later!
Why Choose AirGreen?
Stories like these aren't just about installations; they're about understanding client needs, rising to challenges, and ensuring satisfaction.

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.
