A Masterpiece Installation: Beyond Challenges to Seamless Comfort
In the scenic locale of Delson on the South Shore, AirGreen recently undertook a project that was as challenging as it was rewarding. The mission was clear: to equip a residence with the state-of-the-art Tosot LomoPlus UltraHeat Wall-Mounted Heat Pump. Yet, this was no ordinary installation. The complexity of the task and the ingenious solutions our team provided underline our commitment to delivering unparalleled HVAC services across Montreal, Laval, Longueuil, and the North and South Shores.
The Challenge: A Puzzle of Pipes and Beams
Imagine wanting the ultimate comfort in the heart of your home but facing a labyrinth of plumbing and structural beams that say, "Not so fast." That was the reality for our client in Delson. They desired the indoor unit of their new heat pump smack in the center of their apartment - a request that would stump many. Traditional pathways for the piping - through ceilings or walls - were blocked by insurmountable obstacles.
AirGreen's Innovative Solution
It's here that AirGreen's expertise shone. The impossible became possible with a creative detour: routing the piping externally. Yet, this wasn't just about overcoming physical barriers. Aesthetics mattered too. We didn't just install a heat pump; we ensured it blended seamlessly into our client's home. Collaborating with a professional plasterer, the pipes were masterfully concealed, followed by meticulous drywall and painting work. The result? An impeccable finish that left our client overjoyed with their key-turn solution.
The Tosot LomoPlus UltraHeat: A Closer Look
Our choice of the Tosot LomoPlus UltraHeat Wall-Mounted Heat Pump wasn't coincidental. With its 18,000 BTU capacity and boasting an impressive 24.5 SEER efficiency, this unit represents the zenith of climate control technology. It's not just about heating and cooling; it's about doing so smartly and sustainably. Features like WiFi connectivity, Energy Star® certification, and compatibility with the Hydro-Québec $1,704 grant only add to its allure. Plus, with noise levels as low as 34 dB(A) indoors, it promises whisper-quiet operation.
Specs that Speak Volumes:
- Energy Efficiency: 24.5 SEER rating ensures your energy bills are as low as the temperature it can cool to.
- Connectivity: WiFi inclusion means convenience is always at your fingertips.
- Capacity: Cooling and heating capacity of 18,000 BTU ensures your space is always at the perfect temperature, even when the mercury dips to -30°C.
- Sound: Designed to be seen and not heard, with interior sound pressure levels as low as 34 dB(A).
- Durability: A robust 10-year warranty on parts, compressor, and labor, with an option for an extended 10-10-10 warranty.

This installation story goes beyond placing a heat pump in a challenging location. It embodies our ethos at AirGreen: to tackle each project with a blend of technical prowess and creative problem-solving.

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.
