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.

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.
Unveiling the Sleek and Silent Powerhouse: A Tale of Precision and Customer Satisfaction
The Setting: Saint-Bruno, South Shore
Nestled in the serene locale of Saint-Bruno on the South Shore, our latest installation story unfolds. This area, known for its tranquil ambiance and discerning residents, recently witnessed the meticulous installation of a state-of-the-art Tosot Lomo 23 Wall-Mounted Heat Pump by our adept team at AirGreen.
The Challenge: Balanced Comfort
Our client envisioned a home where comfort permeates every corner without overwhelming any particular space. The goal was clear: achieve a harmonious balance where the heat pump neither scorches nor freezes, but gently cradles the entire apartment in optimal temperature. This vision demanded a machine that could whisper, not roar, allowing work and sleep to proceed undisturbed.
The Tosot Lomo 23: A Symphony of Efficiency and Silence
Enter the Tosot Lomo 23. With its impressive 18,000 BTU cooling capacity and ability to heat efficiently even at -25°C, this model is a silent guardian of comfort. Its dimensions (38.2 x 8.8 x 11.8 interior and 37.6 x 12.6 x 27.6 exterior) embody compact power, while the sound pressure levels (39/47 dB(A) interior and 55.0 dB(A) exterior) ensure that it speaks in soft, unintrusive tones.
- Energy Star® Certified: A badge of honor signifying energy efficiency.
- WiFi Capability (Optional): Modern control for a modern lifestyle.

- Efficiency Rating of 20.0 SEER: High efficiency for sustainable living.

The Installation: A Dance of Precision
The installation process was a ballet of precision and collaboration. The client’s requirement for the head unit to be strategically placed for optimal airflow to the living room set the stage for our team’s expertise to shine. The pipes, those vital conduits of comfort, had to navigate through one room, subtly, silently, like a breeze finding its way. And find its way it did, to the next room where the head unit was to be installed.
Hidden Beauty: The Art of Concealment
But the dance didn’t end there. Every pipe was meticulously concealed, hidden from view, as if they were never there. This was achieved through the masterful hands of a professional plasterer, who worked in tandem with our team. Gyprock was added where necessary, and paint seamlessly blended with the existing palette, resulting in an installation that was as aesthetic as it was functional.
The Result: Seamless Integration for Comfort
The final tableau was one of seamless integration. The Tosot Lomo 23, with its sleek design and silent operation, appeared as though it had always been a part of the home, quietly and efficiently serving its purpose. The client was thrilled, another testament to AirGreen’s commitment to customer satisfaction and excellence in HVAC services.

The big day, step by step
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 would it look like at your place?
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.

Your own project, step by step
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.
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.
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.
