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 Cozy Solution to an Urgent Problem
In the heart of Laval, a simple service call transformed into a tale of reliability, swift action, and undeniable customer satisfaction. AirGreen, your trusted HVAC ally in Montreal, Laval, Longueuil, North Shore, and South Shore, recently showcased its dedication and expertise in maintaining the warmth and comfort of a home, especially one with a newborn. This story revolves around a Gree wall-mounted heat pump, initially installed by us about six years ago with a comprehensive 10-year warranty on all components.
The Heart of Warmth in a Laval Home
Our narrative begins with a Gree wall-mounted heat pump, a pinnacle of heating technology known for its efficiency and durability. Six years ago, AirGreen embarked on a journey with a Laval family to ensure their home would remain a bastion of comfort against the Canadian cold. Our installation came with a promise: a 10-year warranty, a testament to our confidence in the longevity and performance of our services and products.
An Unexpected Chill
However, even the most stalwart of machines can falter. Recently, the homeowner contacted us, concerned that their trusted heat pump was not performing to its usual standards. With a baby in the home, the stakes were higher than ever. The warmth of their home was not just a matter of comfort but of health and safety.
Rapid Response, Rapid Relief
Understanding the urgency, AirGreen mobilized a team of skilled technicians to address the issue on the same day. Our quick response underscores our commitment to our customers' well-being, especially in situations where young family members are involved. Upon inspection, our experts deduced that the solution was straightforward yet vital – the heat pump needed a freon/gaz top-up. This procedure, though simple, requires precision and understanding of the heat pump's workings, emphasizing the importance of professional handling.
Sustained Performance, Sustained Trust
The issue was swiftly resolved, and the heat pump resumed its role as the heart of warmth in the Laval home. This incident not only reasserted the reliability of Gree heat pumps but also highlighted AirGreen's unwavering commitment to its customers. Beyond installation, we ensure that our products continue to perform optimally through years of service. Our team's ability to quickly and effectively address the issue reinforced the homeowner's trust in us, not just as a provider but as a reliable partner in ensuring their home's comfort.

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.
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.
