The Perfect Solution to a Second Floor Summer Dilemma
When faced with the challenge of a sweltering second floor, our team at AirGreen stepped in with a solution that not only met but exceeded our client's expectations. Here's the story of how we transformed a summer discomfort into a year-round haven of comfort.
The Challenge: A Too-Hot Second Floor
Our client, residing in the picturesque Town of Mount-Royal, had a central heating and cooling system that worked wonders for most of their home. However, the second floor remained a stubborn exception. Summer after summer, it transformed into a sauna, leaving the residents searching for a solution.
The Options on the Table
-
Adapting the Central System: This involved adding more ducts to the second floor and upgrading to a more powerful central system. While it seemed like a straightforward solution, it came with a hefty price tag and the potential for significant damage to the home's structure. Economically and practically, it was a no-go.
-
Installing a Wall-Mounted Air Conditioner: The residents initially leaned towards this option, primarily seeking a cooling solution. But when we introduced the idea of a heat pump, the game changed.
Why the Fujitsu LPAS1 Wall-Mounted Heat Pump Was the Winner
-
Government Grants: The difference in cost between a heat pump and a simple air conditioner is marginal, around $50-$100. However, the heat pump qualifies for substantial government grants: a Federal Grant ranging from $2,500 to $5,000 and a Provincial Grant of $560. This made the heat pump an economically savvy choice.
-
Top-Notch Efficiency: With a cooling capacity of 18,000 BTU and an efficiency rating of 20.0 SEER, the Fujitsu LPAS1 is designed to deliver optimal performance without burning a hole in your pocket.
-
Silent Operation: One of the standout features of the Fujitsu machine is its quiet operation. With an exterior sound pressure level of 50.0 dB(A) and an indoor level ranging between 26 and 44 dB(A), it ensures peace and tranquility alongside comfort.
-
Warranty and Assurance: The Fujitsu LPAS1 comes with a comprehensive warranty package - 10 years for the compressor, parts, and labor. Plus, an extended warranty of 10-10-10 is included, ensuring our clients have peace of mind for a decade.
-
Eco-Friendly: The machine uses R-410A gas, which is known for its eco-friendly properties, ensuring our clients make a green choice.
The Installation Process
Given the medium difficulty level of the installation, our team had to ensure precision and expertise. The client's existing central system posed some challenges, but our experienced team navigated them with ease. The result? A seamlessly integrated Fujitsu LPAS1 Wall-Mounted Heat Pump that now cools the once-too-hot second floor, making it a comfortable living space.
A Satisfied Customer
Our client was not just looking for a machine; they were seeking a solution. And that's what we delivered. By understanding their needs, presenting the best options, and executing a flawless installation, we turned a summer problem into a year-round solution. The Fujitsu LPAS1, with its impressive features and the added advantage of government grants, proved to be the perfect fit.

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.
