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 Heroic Save: A Heat Pump Reborn
In the scenic neighborhood of Pierrefonds-Roxboro, nestled amidst vibrant green spaces and family-friendly streets, we encountered a wall-mounted heat pump desperately in need of attention. As HVAC specialists at AirGreen, we take pride in every project we undertake, and this one was no exception. Our mission was simple yet critical: diagnose the problem, restore comfort, and ensure our customer was smiling by the end of the day.
The Initial Call: "It's Just Not Working"
Our client reached out, sharing a frustrating problem many homeowners fear: a heat pump that wasn’t heating or cooling properly. In the midst of Montreal's unpredictable weather swings, having a non-functional HVAC system is more than an inconvenience—it’s a major disruption. Our team knew we had to act swiftly.
Assessing the Situation: The Leak Hunt
Armed with advanced diagnostic tools and our years of expertise, we made our way to Pierrefonds-Roxboro. Upon arrival, we noticed signs of inefficiency. The air felt lukewarm when it should have been crisp and refreshing, and the heating performance was just as lackluster. Our technicians quickly put on their detective hats and began inspecting every component of the unit.
The Culprit Revealed: A Refrigerant Leak
Using our infrared thermal detector, we pinpointed the source of the issue—a sneaky refrigerant leak that had been undermining the system’s performance. Refrigerant is the lifeblood of any heat pump, and even a minor leak can compromise the entire operation. We took swift action to address it.
A Step-By-Step Solution: Bringing the Heat Pump Back to Life
- Leak Repair and Sealing: We meticulously sealed the leak, ensuring that no trace of refrigerant could escape again. The integrity of the system is crucial, and we triple-checked our work to guarantee it.
- Recharging with Precision: Next, we added the necessary freon (refrigerant) to restore the unit's cooling and heating capacities. Our technicians take pride in precise measurements, knowing that even a slight deviation can impact performance.
- Thorough System Check: After the refrigerant levels were restored, we conducted a comprehensive test. The system roared back to life, and the air coming out was now refreshingly cool or warmly comforting, depending on the mode.
The Results: A Happy Customer and a Happy Heat Pump
Our client couldn't believe the transformation. What had been a frustrating, underperforming unit was now working like new, ready to tackle Montreal's summers and winters with ease. Seeing our customers satisfied is the ultimate reward, and it’s why we do what we do.

Maintenance Tips for Your Wall-Mounted Heat Pump
To keep your heat pump running smoothly and efficiently, follow these tips:
- Regular Filter Cleaning: A clogged filter can reduce airflow and strain your system. We recommend cleaning or replacing filters every 2-3 months.
- Seasonal Check-Ups: Schedule a professional maintenance visit at least once a year. Prevention is the key to long-lasting performance.
- Watch for Warning Signs: If your heat pump isn’t performing well or you notice unusual sounds, call a professional before it worsens.
The Technology Behind It: Understanding Your Heat Pump
Wall-mounted heat pumps are marvels of engineering, designed to extract heat from the outside air and transfer it inside during the colder months, and vice versa during the summer. By using a refrigerant to facilitate this transfer, these systems are both energy-efficient and environmentally friendly. However, any disruption in the refrigerant cycle—like a leak—can severely impact performance.
Why Refrigerant Levels Matter
Refrigerant doesn’t just make your heat pump work; it’s essential for optimal efficiency. A well-maintained system can save up to 30% on energy bills compared to a poorly maintained one.
