A Symphony of Efficiency and Silence: Discover Our Latest HVAC Masterpiece
Installation in Verdun: A Story of Precision and Expertise
Nestled in the vibrant Verdun neighborhood of Montreal, our latest installation project tells a story of precision, expertise, and unparalleled customer satisfaction. At AirGreen, we don’t just install HVAC units; we create comfort, transforming every home into a sanctuary of warmth and tranquility.
The Client’s Vision: Silent, Powerful, and Reliable
Our journey began with a client who had a clear vision: a silent, powerful, and reliable HVAC system to energize a spacious open-concept apartment. With an old 18,000 BTU unit at the end of its life, an upgrade was imperative. The client’s wish list was strict, but at AirGreen, we thrive on challenges.
Introducing the Gree Extreme: Performance and Silence United
- Cooling Capacity: A robust 24,000 BTU ensuring optimal temperature control
- Heating Efficiency: Unwavering performance in temperatures as low as -30°C, providing consistent warmth
- Silence is Golden: With an indoor sound pressure level ranging from 34 to 54 dB(A), and an outdoor level at 59.0 dB(A), the Gree Extreme whispers comfort.
- Energy Efficiency: With a SEER rating of 21.5 and Energy Star® certification, it’s an eco-friendly machine in every way.
- Warranty: A ten-year coverage for the compressor, parts, and labor, with an extended warranty option available.
The Installation Process: A Ballet of Technical Skill
With the Gree Extreme as our canvas, our team of seasoned professionals undertook a meticulous installation process. The client’s request to use existing pipes was not only met but executed with finesse, without additional holes or structural modifications to the apartment. Each pipe was inspected, cleaned, and validated for integrity, setting the stage for the Gree Extreme to unleash its full potential.
Grants Galore: Maximizing Value for Our Client
The installation was not just about technical precision; it was also a dance of financial prudence. With the Gree Extreme eligible for a significant federal grant of $2,500 to $5,000 and a provincial grant of $1,860, our client’s investment was offset by substantial savings, making the deal even more attractive.
Customer Satisfaction: The True Measure of Success
As the Gree Extreme kicked into action, spreading absolute comfort throughout the large open space, our client’s joy was boundless. The symphony of efficiency and silence was played to perfection, meeting every item on the wish list. At AirGreen, we don’t just deliver products; we keep our promises, engraving smiles on our clients’ faces, one installation at a time.

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.
