Restoring Comfort and Efficiency: A Unique Service Story in Outremont
When a customer in Outremont reached out to us about their aging Sanyo ductless heat pump, they weren’t sure if it could be salvaged. The unit had been their go-to source for year-round comfort, but persistent issues had left them doubting its future. With many years of experience in HVAC service and repair, we saw this as an opportunity to not only fix the problem but also to reaffirm our commitment to delivering exceptional service. What followed was a meticulous process that brought the Sanyo heat pump back to life and highlighted why AirGreen is the trusted name for HVAC solutions in Montréal, Laval, Longueuil, Rive Nord, and Rive Sud.
Diagnosing the Problem: The First Step to Success
Our team arrived at the Outremont residence prepared to inspect and troubleshoot the unit. The homeowner explained that the heat pump had been struggling to maintain consistent temperatures, and there were concerns about unusual noises emanating from the system. After a thorough diagnostic assessment, we identified the root causes:
- Clogged air filters that restricted airflow.
- A minor refrigerant leak affecting the unit's cooling efficiency.
- Wear and tear on the fan motor, leading to the strange noises.
While these issues might seem daunting, they were challenges our technicians were well-equipped to handle.
The Repair Process: Precision and Expertise
Cleaning and Restoring Airflow
The first step was addressing the clogged air filters. Using professional-grade tools, we removed years of accumulated dust and debris. Clean filters are essential for maintaining airflow, energy efficiency, and air quality—a cornerstone of any well-functioning heat pump.
Sealing the Refrigerant Leak
Next, our team tackled the refrigerant leak. After isolating the damaged section of the line, we used advanced sealants to ensure no further leakage. We then recharged the system with the appropriate refrigerant to restore its cooling capabilities. This step required precision, as incorrect handling of refrigerants can lead to inefficiencies or environmental harm.
Repairing the Fan Motor
Finally, we turned our attention to the fan motor. The worn-out bearings were replaced, and the motor was calibrated to operate quietly and efficiently. This repair not only resolved the noise issue but also extended the lifespan of the unit.
The Outcome: A Unit as Good as New
After completing the repairs, we ran the heat pump through rigorous performance tests. The system was now operating at peak efficiency, providing consistent heating and cooling throughout the home. The customer was thrilled to learn that their Sanyo unit, once on the brink of replacement, now had several more years of reliable service ahead.

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.
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

- 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.

- 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.
