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.

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.
Transforming Comfort with a Silent and Efficient Upgrade
A Seamless Transition in Charlemagne, North Shore
At AirGreen, we recently had the pleasure of enhancing comfort for a household in Charlemagne, North Shore, through the meticulous installation of a Tosot LomoPlus UltraHeat Wall-Mounted Heat Pump. This installation was not just about replacing an old, inefficient unit; it was a comprehensive upgrade to a home’s comfort system, ensuring efficiency, quiet operation, and reliability.
Choosing the LomoPlus UltraHeat: A Decision Well Made
Our customer was previously burdened with a system that was not only excessively noisy but also ineffective at providing heat under the chilling conditions of -10°C. The need for a unit that could seamlessly fit into the existing infrastructure, with the same 1/4 - 1/2 pipes, while bringing forth significant improvements in efficiency, noise levels, and warranty, was evident. The Tosot LomoPlus UltraHeat emerged as the undisputed choice.
- Cooling Capacity: A robust 12,000 BTU
- Heating Capacity: Uninterrupted warmth, even at -30°C
- Efficiency: An impressive SEER rating of 30.5
- Warranty: Unparalleled 10-year coverage on compressor, parts, and labor
- Silent Operation: With an exterior sound pressure level of just 53.0 dB(A) and an interior range between 22 and 49 dB(A), it whispers comfort.
Installation Day: A Tale of Precision and Care
The installation day was marked by our team’s unwavering attention to detail and commitment to excellence. Before the new unit could claim its place, the old pipes underwent a thorough examination for any signs of wear, cracks, or holes. Upon confirming their integrity, the pipes were cleaned and prepped for the new installation.
Navigating Challenges with Ingenuity
Access to the rooftop posed a challenge, but not one too significant for our adept team. With no straightforward access available, innovative thinking led us to approach the neighbor, whose balcony provided the perfect pathway to the rooftop. The spirit of community cooperation, coupled with our team’s expertise, saw the compressor reaching its destination without the need for special equipment or additional costs.
A Symphony of Silence and Efficiency
Post-installation, the silence was almost as palpable as the comfort. The new Tosot LomoPlus UltraHeat is a symphony of silent operation and efficient performance, much to the delight of both our customer and their neighbor. With its whisper-quiet operation, it’s a neighbor-friendly addition to the home.
Grants and Savings: The Icing on the Cake
The installation not only brought comfort but also significant savings, thanks to the eligibility for Federal and Provincial Grants amounting to $2,500/$5,000 and $405 respectively. It’s an investment that pays back, bringing warmth and cooling efficiently and economically.
Conclusion: Another Happy Customer in the AirGreen Family
This installation story is one of many, but each one is unique. It’s a tale of old giving way to new, of challenges met with ingenuity, and of ultimate customer satisfaction. At AirGreen, every installation is a promise of quality, care, and comfort delivered. The Tosot LomoPlus UltraHeat in Charlemagne is another testament to our commitment to bringing comfort home, quietly and efficiently.
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.
