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.
Efficiency Meets Innovation: A Tosot Tale
At AirGreen, we pride ourselves not only on our technical expertise but also on our commitment to providing our customers with solutions that truly fit their needs. Our recent installation in Boucherville, on the picturesque South Shore, serves as a testament to our dedication and our customers' trust in us. Here’s a look into how we delivered exceptional service with the Tosot LomoPlus UltraHeat DoubleZone Heat Pump.
Understanding the Installation Site and Client Needs
Our team was tasked with a challenging installation in a cozy home nestled in the serene town of Boucherville. The client sought a heating solution that was both potent and unobtrusive, a feat that required careful consideration given the aesthetic and functional needs of their space. With an 18,000 BTU compressor powering two 9,000 BTU indoor units, the Tosot LomoPlus UltraHeat model was a perfect match.

Challenges Overcome
Installing a dual-zone system like the LomoPlus UltraHeat requires precision and expertise, especially when space and noise are major concerns for the client. Our team successfully navigated these challenges by strategically placing the indoor units to maximize airflow without disrupting the home's decor. The outdoor unit was installed with a special heating base, ensuring it remains efficient even when the mercury drops below freezing.
Client Satisfaction and Beyond
The highlight of this installation was not just in meeting the technical specifications but in exceeding our client's expectations. Their initial concern was how such a compact system could achieve the desired comfort levels without noise. Not only did the installation prove to be whisper-quiet, but it also delivered exceptional warmth, courtesy of its advanced heat pump technology. The client was so pleased with the outcome that they recommended AirGreen to a neighbor, further validating the success of our installation.
A Step Toward Sustainability
By opting for the Tosot LomoPlus UltraHeat, our client also took advantage of the LogisVert Grant by Hydro-Québec, receiving a $2,040 subsidy. This initiative not only supports our commitment to promoting sustainable solutions but also makes it economically feasible for our customers to upgrade to more efficient systems.

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.
