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.
Enhancing Comfort in Châteauguay with AirGreen’s Expertise
At AirGreen, we pride ourselves on transforming homes into havens of comfort and energy efficiency. Our latest installation in Châteauguay is a testament to our commitment to quality and customer satisfaction. This project involved the installation of a Gree Vireo GEN3 18,000 BTU wall-mounted heat pump, a system renowned for its reliability, performance, and modern features. Let us take you through this exciting project, which showcases why we are the trusted choice for HVAC solutions in Montreal, Laval, Longueuil, and the Rive Sud and Rive Nord areas.
Understanding the Homeowner’s Needs
The homeowners in Châteauguay had been seeking an HVAC solution that offered year-round comfort without compromising energy efficiency. Living in Québec’s unique climate, they needed a system capable of handling extreme cold temperatures while ensuring optimal cooling during summer. After a thorough consultation, we recommended the Gree Vireo GEN3 18,000 BTU ductless heat pump. With its ability to heat efficiently at temperatures as low as -30°C and its impressive cooling capacity, this model was the perfect fit.
Why the Gree Vireo GEN3 Stands Out
The Gree Vireo GEN3 is not just another heat pump; it’s a cutting-edge solution designed for modern homes. Here’s what makes it exceptional:
- Energy Efficiency: With a 23.0 SEER rating, this system is Energy Star® certified, ensuring maximum energy savings while reducing environmental impact.
- Heating Capacity: Designed to perform in the harshest winters, the Vireo GEN3 can operate seamlessly at temperatures as low as -30°C, making it ideal for Québec’s icy winters.
- Cooling Excellence: With a robust 18,000 BTU cooling capacity, this mini split ensures every corner of the home stays refreshingly cool during summer.
- Smart Features: Integrated WiFi compatibility allows the homeowners to control their system remotely, adding convenience and modern functionality.
- Quiet Operation: With indoor sound levels as low as 31 dB(A), this unit operates so quietly that it’s barely noticeable, enhancing the home’s tranquility.
The Installation Process: Precision and Expertise
Installing a heat pump is more than just attaching units; it’s a precise process that demands expertise and attention to detail. Here’s how we ensured a flawless installation:
Step 1: Site Inspection and Preparation
Our team began with a detailed site inspection to determine the best placement for the indoor and outdoor units. In Châteauguay’s charming residential neighborhood, aesthetics and functionality were equally important. The outdoor unit was installed on a sturdy base to prevent vibrations and ensure stability, while the indoor unit was mounted in a central location to optimize airflow.
Step 2: Mounting the Indoor Unit
The sleek indoor unit, with its dimensions of 38.63 x 8.75 x 12.25 inches, was carefully installed to complement the home’s interior. We ensured proper insulation and sealing to prevent energy loss and maintain system efficiency.
Step 3: Installing the Outdoor Unit
The outdoor unit, measuring 38 x 15.63 x 27.63 inches, was placed on vibration-dampening pads and positioned away from obstructions to allow optimal airflow. With a noise level of only 57 dB(A), this unit operates quietly without disturbing the serene surroundings.
Step 4: Connecting the System
Using high-quality refrigerant pipes (1/4 - 5/8 dimensions) and R-410A refrigerant, we connected the indoor and outdoor units. Our technicians ensured all connections were secure and leak-free, guaranteeing the system’s longevity.
Step 5: Testing and Calibration
Before completing the job, we rigorously tested the system to ensure it performed optimally in both heating and cooling modes. Calibration was fine-tuned to match the homeowners’ preferences, delivering the ultimate in personalized comfort.
Admissible Grants: Saving Money While Enhancing Comfort
One of the standout advantages of this installation is its eligibility for the LogisVert Grant by Hydro-Québec, amounting to $385. We guided the homeowners through the application process, helping them benefit from this financial incentive while enjoying a state-of-the-art HVAC system. Additionally, the Vireo GEN3 qualifies for a provincial subsidy of $570, making it an even smarter investment.

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.
