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 Tailored Cooling Solution That Beats the Heat and the Competition
Mastering the Challenge of Custom Installation
In the heart of Brossard on the South Shore, a remarkable installation story unfolded as AirGreen tackled one of its more complex HVAC projects. This tale isn't just about setting up a Tosot LomoPlus UltraHeat; it's a narrative of precision, planning, and customer satisfaction that sets AirGreen apart in the competitive landscape of HVAC solutions.
Our recent project involved a customized approach where the client desired not one but three separate Tosot LomoPlus heat pumps. This strategic decision, aimed at maximizing efficiency and reducing operational risk, underscores our commitment to delivering personalized solutions that genuinely reflect the unique needs of our customers.
The Advantages of Multiple Units Over Multi-Zone Systems
Opting for three individual units rather than a single triple-zone system, we ensured that each unit could operate independently. This setup minimizes the risk associated with potential unit failures—maintaining comfort in other zones without interruption. The customer's choice was influenced by several key factors:
- Reduced Risk of Complete Downtime: If one unit encounters an issue, the others continue functioning, ensuring continuous comfort.
- Enhanced Performance: Each unit operates optimally under the conditions it's specifically installed for, maximizing efficiency.
- Ease of Maintenance and Servicing: Individual systems simplify the servicing process, allowing for quicker, more efficient repairs.
Efficient and Silent: The Tosot LomoPlus UltraHeat
The Tosot LomoPlus UltraHeat model stands out for its remarkable efficiency and whisper-quiet operation. Here’s what makes this model a top choice for discerning clients:
- High Efficiency: With an impressive SEER rating of 30.5, this model is one of the most efficient on the market, drastically reducing electricity usage.
- Ultra-Quiet Operation: The indoor unit operates at a minimal 22 dB(A), ensuring a virtually silent environment, perfect for residential areas.
- Superior Heating Capacity: Even in the harsh Canadian winters, with temperatures dropping to -30°C, the LomoPlus continues to provide reliable and efficient heating.
Client Satisfaction: A Testament to Quality
The completion of this installation was not just about technical prowess but also about ensuring client satisfaction. The homeowner was particularly impressed with the seamless integration of the units into their home, the professional demeanor of our dual installation teams, and the significant economic benefits, including a substantial federal grant of $5,000. These aspects highlight our dual commitment to excellence and client satisfaction:
- Day-Same Installation: By coordinating two teams, we completed the installation of all three units in one day, minimizing disruption to the homeowner.
- Economic Benefit: Besides enjoying reduced energy bills, the client benefited from significant grants, making this investment even more rewarding.
A Commitment to Sustainability and Comfort
The Tosot LomoPlus UltraHeat isn't just a testament to advanced engineering but also to sustainable living. Certified by Energy Star and eligible for the $405 LogisVert grant from Hydro-Québec, this model aligns with our mission to support environmentally responsible heating and cooling solutions.

And 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.
