Take a tour of the installation
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.
A Seamless Blend of Efficiency and Elegance
Choosing the Perfect Spot
When it comes to HVAC installations, location is everything. Our recent project in Pierrefonds-Roxboro, Montreal, was no exception. The homeowner had a clear vision: a Mini Split that would seamlessly integrate into their living space, providing optimal heating and cooling without being obtrusive. After considering multiple spots, we zeroed in on the perfect location where the Mini Split could directly blow into the living room. This strategic placement ensures that the entire floor benefits from consistent temperatures, creating a comfortable environment year-round.
Silence is Golden
Nobody likes a noisy HVAC system. That's why our customer's emphasis on a silent machine was paramount. The Tosot Lomo 23 Mini Split boasts an impressive interior sound pressure level of just 29/45 dB(A), ensuring that family movie nights or quiet evenings are never interrupted. It's the kind of silence that speaks volumes about its quality.
Power-packed Performance
Let's dive into the heart of this machine:
- Cooling Capacity: A robust 12,000 BTU ensures that even on the hottest summer days, comfort is just a button press away.
- Heating Capacity: Ready to brave temperatures as low as -25°C, this Mini Split is built for Montreal's chilly winters.
- Efficiency: With a 22.0 SEER rating, it's not just about power but also how efficiently that power is used.
- Warranty: A comprehensive 10-10-10 warranty (Compressor - Parts - Labor) stands as a testament to the machine's durability and our trust in its performance.
Sleek and Stylish
Beyond performance, the Tosot Lomo 23 is a marvel of design:
- Dimensions: The interior unit, with dimensions of 33.4 x 8.2 x 11.4, is sleek and unobtrusive, while the exterior unit, measuring 33.4 x 12.6 x 23.6, is compact and easy to accommodate.
- Energy Star® Certification: An affirmation of its energy efficiency.
- AHRI Number: 9108746, a mark of its quality and performance standards.
Grants and Savings
One of the highlights of this installation was the availability of substantial grants. The model qualifies for a Federal Grant of up to $5,000. Additionally, a Provincial Grant of $385 further sweetened the deal. Quality, performance, and savings? It's a trifecta that's hard to beat!
A Job Well Done
Our commitment to excellence isn't just about the products we offer but also how we install them. For this project, our team went above and beyond to ensure a clean installation. No visible holes, no unsightly wires, just a sleek Mini Split that looks like it was always meant to be there. Our customer's delight at the end of the project was the cherry on top of a job well done.

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.
