Experience Superior Climate Control Year-Round in Your Home
When it comes to achieving a perfect indoor climate, AirGreen stands out as a trusted name in the HVAC industry, especially for complex and demanding projects across the Greater Montreal area. Recently, we completed an impressive installation in Boisbriand, where we transformed a standard living space into a haven of comfort and energy efficiency using the latest Tosot LomoPlus UltraHeat 12,000 BTU wall-mounted air conditioner. Let’s dive into what makes this project truly unique and why this model is the ultimate choice for Canadian homeowners.
Setting the Scene: Boisbriand’s Weather Challenges
Boisbriand, known for its blend of urban convenience and suburban tranquility, also faces the extremes of Canadian weather. With freezing temperatures in winter and sweltering summer days, maintaining an ideal indoor climate can be a challenge. That’s where our expertise came in. The homeowners needed a versatile solution that provided reliable cooling during heatwaves and robust heating capacity for sub-zero conditions, all while keeping energy bills in check.
Our choice? The Tosot LomoPlus UltraHeat 12,000 BTU. This unit doesn’t just perform; it excels, even in extreme climates.
Why the Tosot LomoPlus UltraHeat Stands Out
Exceptional Performance in All Seasons
One of the standout features of the Tosot LomoPlus UltraHeat is its impressive heating capacity, even at -30°C. Equipped with Gree’s two-stage inverter technology, this unit ensures homeowners remain warm and cozy throughout harsh winters. In cooling mode, it maintains an energy-efficient operation with a cooling capacity of 12,000 BTU, making it perfect for medium-sized living spaces.
Key Specifications:
- Cooling Capacity: 12,000 BTU
- Heating Capability: Effective down to -30°C
- Efficiency: 30.5 SEER, making it one of the most efficient units in its class
- Voltage: 220V, designed for reliable and powerful performance
- Sound Levels: Whisper-quiet operation, with only 22 dB indoors, ensuring peace and tranquility
Smart Design, Seamless Integration
This installation wasn’t just about performance; aesthetics were crucial too. The sleek indoor unit measuring 39.2 x 8.8 x 11.8 inches fit seamlessly into the home’s interior design, while the compact outdoor unit (35.3 x 14.8 x 23.4 inches) was carefully placed to minimize noise and maximize efficiency. We used high-quality R-410A refrigerant, known for its eco-friendly properties and efficiency.
Our installation team ensured that the piping and electrical connections were discreetly arranged, maintaining the clean lines and overall beauty of the living space. With WiFi-enabled controls, the homeowners can now manage their indoor climate remotely, making it easier than ever to come home to comfort.
Unique Features and Technological Advancements
1. Energy Efficiency That Saves You Money
The Tosot LomoPlus boasts a remarkable SEER rating of 30.5, ensuring minimal energy consumption without sacrificing performance. The LogisVert Grant by Hydro-Québec makes this model even more appealing, offering homeowners a generous $972 rebate. This makes it not only an efficient choice but also a cost-effective investment in long-term energy savings.
2. Intelligent Defrost Technology
Unlike traditional heat pumps that waste energy on frequent defrost cycles, this unit features intelligent defrosting. It activates only when necessary, conserving energy and keeping the system running efficiently.
3. Silent Yet Powerful
No one likes a noisy air conditioner. Thankfully, the Tosot LomoPlus operates quietly at just 22 dB indoors—equivalent to a whisper. Even the exterior unit, at 53 dB, is designed to minimize disturbance, making it perfect for urban and suburban neighborhoods like Boisbriand.
Installation Details: A Job Done Right
At AirGreen, we believe that a great product needs an equally great installation. Our expert technicians worked meticulously, ensuring the 1/4 - 1/2 inch piping was perfectly set to deliver optimal performance. Special attention was given to insulation and sealing, as any minor gap can impact efficiency. The 220V connection was carefully installed to match the home’s electrical system, ensuring safe and reliable operation.
We also took time to explain the self-diagnosis feature to the homeowners. This built-in system detects issues and alerts a technician, reducing potential service call times. It’s another way the Tosot LomoPlus UltraHeat keeps things running smoothly.
The AirGreen Difference: Why Choose Us?
Our commitment to customer satisfaction doesn’t end with the installation. We offer an extended 10-year warranty on parts and labor, guaranteeing peace of mind. We also provide regular maintenance services, as a well-maintained unit ensures peak performance and longevity.
Customer Feedback: A Comfortable and Efficient Home
The homeowners were delighted with how seamlessly the installation fit into their daily life. They were especially pleased with the fast temperature adjustments and the convenience of the WiFi control. The whole family now enjoys year-round comfort, with significant savings on their energy bills.
A Smart Investment for the Future
If you live in the Greater Montreal area, Laval, or the South Shore, a Tosot LomoPlus UltraHeat installation by AirGreen is one of the smartest investments you can make for your home. Beyond the substantial energy savings and comfort, our installations are backed by a decade of reliable support, ensuring your system serves you well through every weather challenge.

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.
