Exceptional Air Conditioning Installation: Tosot LomoPlus UltraHeat in Boucherville
Powerful, Efficient, and Ready for Canadian Winters
In Boucherville, a city known for its chilly winters and humid summers, keeping homes comfortable year-round is a must. That’s why we at AirGreen were thrilled to install the Tosot LomoPlus UltraHeat wall-mounted air conditioner for our client in this scenic location. This 18,000 BTU powerhouse is built to perform under the harshest weather conditions, making it ideal for both cooling during hot summer days and heating in the dead of winter when temperatures drop to as low as -30°C.
Why the Tosot LomoPlus UltraHeat Stands Out
The Tosot LomoPlus UltraHeat isn’t your average air conditioning unit. Known for its high efficiency and durability, this model combines exceptional cooling and heating capabilities with modern technology. It’s rated Energy Star® and comes with a remarkable 24.5 SEER efficiency rating, ensuring our client in Boucherville can enjoy consistent comfort without a huge spike in their energy bills. Plus, this model is equipped with WiFi capability, allowing remote control from anywhere, adding convenience to its long list of features.
Installation Details – Crafting Comfort for Every Corner
Our team completed this installation with meticulous attention to detail. The indoor unit, with dimensions of 43.3 x 9.8 x 12.8 inches, was strategically placed to ensure optimal airflow throughout the room. Meanwhile, the outdoor unit, sized at 38.5 x 16.8 x 31.1 inches, was carefully positioned to minimize noise and maintain the aesthetic of the property. With an indoor sound pressure level ranging from 34 to 51 dB(A) and an outdoor level at 59.0 dB(A), this system is whisper-quiet—ideal for peaceful living without distractions.
Cutting-Edge Features of the Tosot LomoPlus UltraHeat
- Two-Stage Compressor: This advanced feature ensures that the unit operates efficiently in both mild and extreme temperatures, maintaining up to 80% heating capacity even at -30°C.
- Intelligent Defrost: The defrosting system activates only when needed, helping to maximize energy savings and prevent unnecessary operation.
- Memory Function: In the event of a power outage, the system restarts with its previous settings, ensuring a seamless experience for the user.
- I Feel Mode: The remote control can detect room temperature, adjusting cooling and heating based on where the remote is, not just where the indoor unit is installed.
- Turbo Mode: For those times when you need quick temperature adjustments, Turbo Mode rapidly increases airflow to reach your desired comfort level faster.
Taking Advantage of Hydro-Québec’s LogisVert Grant
As part of our commitment to providing value to our clients, we made sure the homeowner was aware of the $1,704 LogisVert Grant from Hydro-Québec for which this unit qualifies. This grant is available for energy-efficient installations, helping homeowners offset the initial investment and enjoy long-term savings on energy costs.
Long-Lasting Peace of Mind with Extended Warranty
The Tosot LomoPlus UltraHeat comes with an industry-leading warranty: 10 years on the compressor and parts. For those who prefer extra assurance, an extended 10-year labor warranty is also available. At AirGreen, we believe in delivering not only quality installations but also lasting support for our customers. This extended warranty provides peace of mind, knowing that their investment is protected for the next decade.
The Installation Journey: How We Made It Happen
This installation was no ordinary project. We started by assessing the home’s layout, ensuring that every corner would benefit from the Tosot LomoPlus UltraHeat’s powerful airflow. Once the planning phase was complete, we mounted the indoor unit in a central location, allowing for effective air distribution. The outdoor unit, meanwhile, was installed on a stable base, with careful attention to vibration reduction and aesthetic appeal.
We then connected the units with durable piping, using a 1/4 - 5/8 pipe size to guarantee optimal refrigerant flow. Finally, we tested the system, verifying its efficiency and fine-tuning settings to ensure our client could enjoy immediate comfort as soon as we left.
Efficient, Quiet, and Environmentally Friendly
One standout feature of the Tosot LomoPlus UltraHeat is its eco-friendly R-410A refrigerant. Unlike older refrigerants, R-410A has a lower environmental impact, aligning with our commitment to sustainable HVAC solutions. Additionally, the low sound levels mean that this unit operates almost silently, blending seamlessly into our client's home life without any disruptive noise.
Advanced Technology for Total Control
This model’s WiFi compatibility allows homeowners to control the system directly from their smartphones. Imagine being able to turn on the heating during a snowy commute, so your home is warm by the time you walk in the door. It’s not just a feature; it’s a lifestyle improvement, making life in Boucherville a little bit easier and more comfortable.

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.

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.

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.

- 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.
