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.
A Symphony of Power and Silence: Unveiling a Masterpiece Installation
Introduction to Excellence
In the prestigious neighborhood of Westmount, Montreal, we at AirGreen recently accomplished an installation that is nothing short of a masterpiece. This was not just another routine installation; it was a challenging endeavor, meticulously executed to meet the exacting demands of our discerning customer.
The Silent Powerhouse: Gree FreeMatch Extreme
The star of this installation is the Gree FreeMatch Extreme DoubleZone Heat Pump. This machine is a paragon of efficiency and silent operation, boasting a cooling capacity of 24,000 BTU and an unparalleled ability to heat even at a bone-chilling -35°C. With an impressive Energy Star® rating, WiFi capabilities, and a 10-year warranty on compressor, parts, and labor, this model is a testament to Gree’s commitment to quality and innovation.
- Silent Operation: With a sound pressure level of just 60.0 dB(A), the FreeMatch Extreme operates whisper-quietly, ensuring peace for both the homeowner and the neighbors.
- Efficiency: With a 23.0 SEER efficiency rating, this model is designed to optimize energy consumption while delivering top-notch performance.
- Extended Warranty: The included extended warranty covers 10 years for the compressor, parts, and labor, offering peace of mind for a decade.
Crafting Perfection: The Installation Journey
Our customer had specific requirements that needed expert handling. The previous HVAC unit was a noisy affair, creating discomfort for everyone in its acoustic vicinity. Moreover, it failed to provide uniform heating and cooling across the floor, leading to areas that were either too hot or too cold.
Understanding these concerns, we opted for a DoubleZone Heat Pump with two separate 12,000 BTU heads. The dual heads were strategically placed on either side of the floor to ensure even distribution of heat and cool air, creating a comfortable and consistent indoor climate throughout the space.
Overcoming Challenges: A Tale of Precision and Skill
The installation of the first 12,000 BTU head was straightforward as it was located on the same wall as the compressor. However, the second head posed a challenge, requiring us to navigate through the apartment intricately. With precision and care, we threaded pipes through walls and ceilings, ensuring a seamless integration without disrupting the aesthetic integrity of the home.
Finishing Touches: Turn-Key Installation
Post-installation, our collaboration with a professional plasterer added the finishing touches to the project. The plasterer expertly applied gyprock and color-matched paint where needed, resulting in a polished, turn-key installation that left the space looking pristine and untouched.
Grants and Savings: The Icing on the Cake
The Gree FreeMatch Extreme is eligible for a substantial federal grant of $2,500 to $5,000 and a provincial grant of $895. These grants, coupled with the unit’s energy efficiency, translate into significant savings for the homeowner, making it an investment that is as economically wise as it is functionally outstanding.
A Happy Ending: Another Satisfied Customer
Our customer was thrilled with the outcome. The new HVAC system not only met but exceeded expectations, offering silent operation, powerful performance, and aesthetic integration into the living space. With the added bonus of grants and a decade-long warranty, this installation story had a happy ending, with another satisfied customer joining the AirGreen family.
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.
