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.
Efficient Service Call to Restore Comfort in Your Home
At AirGreen, we understand the importance of having a reliable heating and cooling system, especially during seasonal changes. Recently, we were pleased to respond to a service call for the repair of a Daikin wall-mounted heat pump in Chambly. In this article, we will explain the details of this intervention and how our team of experts efficiently resolved the issues faced by our client.
Performance Issues with a Daikin Heat Pump
Like any appliance, a wall-mounted heat pump can run into problems from time to time, as was the case with this unit in Chambly. The client reached out to us due to an apparent malfunction: the indoor unit was no longer blowing cool air despite the high room temperature. This situation is often related to problems with airflow, refrigerant leaks, or even a fan motor failure.
Diagnosis and Identifying the Problem
Upon arriving at the site, our technicians conducted a thorough diagnosis to pinpoint the root cause of the issue. After a detailed inspection, we identified a refrigerant leak in the outdoor unit, a problem that prevents the system from functioning efficiently. Additionally, a slight obstruction in the ventilation system was found, contributing to the unit's poor performance.
Repair and Replacement of Faulty Components
Once the problem was identified, we took the necessary steps to resolve the situation. We first performed a refrigerant leak repair, replacing the defective pipe and recharging the system with the appropriate refrigerant. Then, we cleaned and cleared the ventilation system to allow for better airflow and restore the air conditioner's efficiency. Finally, an in-depth inspection of the fan motor was carried out to ensure that it was functioning correctly.
Our technicians then tested the system's overall performance to ensure that the heat pump was operating at full capacity, restoring the client's comfort immediately.
Results: Restored Comfort and Optimized Equipment
Once the repairs were completed, the Daikin heat pump was back to optimal performance, providing cool and comfortable air throughout the room. The client expressed satisfaction after seeing an immediate improvement in the temperature and a significant reduction in their energy bills, thanks to the restored efficiency of the system. At AirGreen, we make sure every intervention is a success, and this repair was no exception.

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.
