A Tale of Transformation and Satisfaction
When the summer heat waves hit and the winter frosts loom on the horizon, the importance of a reliable HVAC system becomes undeniably clear. AirGreen, a trusted name in HVAC solutions in Montréal, recently had the privilege of transforming a frustrating situation into a story of satisfaction and comfort with the installation of a Windair 17 Mini Split.
Project Background
In the heart of Montreal, a homeowner faced a vexing challenge. Their old 12,000 BTU system had failed after just five years of service, leaving them not only uncomfortable but also disappointed with the lack of support from their previous HVAC contractor. In their quest for a replacement, the homeowner's criteria were stringent: compatibility with existing infrastructure, cost-effectiveness, high quality, and an uncompromising warranty.
The Perfect Match
Enter the Windair Series 17, a marvel of modern HVAC technology, known for its robust 17.0 SEER efficiency rating. This unit wasn't just a replacement; it was an upgrade. AirGreen stepped in, answering the call for a new system that reused the existing pipes and electrical wiring, ensuring a seamless transition.
Efficient Installation Process
The installation process exemplified precision and professionalism. AirGreen's technicians performed an immaculate installation on the rooftop for the external unit, meticulously ensuring that every component aligned perfectly with the existing setup. The internal unit, sleek and unobtrusive, was mounted to complement the aesthetics of the home while promising peak performance.
Features that Define Excellence
- Superior Energy Efficiency: With a 17.0 SEER rating, the Windair 17 is designed to optimize energy use, reducing electricity bills significantly.
- Whisper-Quiet Operation: At a mere 28 dB(A), the indoor unit operates almost silently, enhancing the comfort of home environments.
- Robust Warranty: Offering a 10-year warranty on both parts and compressor, Windair stands firmly behind their product.
- Advanced Inverter Technology: The INVERTER compressor adapts its output based on real-time cooling and heating demands, ensuring efficient operation and longevity.
- Eco-Friendly: Using R-410A refrigerant, the Windair 17 is not only energy-efficient but also environmentally responsible.
Client's Delight
Post-installation, the homeowner expressed immense satisfaction. The swift and efficient installation, coupled with the significant upgrade in system quality and the assurance of a solid warranty, turned their initial dismay into a testimonial of delight. They praised AirGreen for their responsiveness, expertise, and clean installation work.

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.
