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.
Servicing a Trane heat pump in the middle of winter in Ville-Marie: A challenge tackled by AirGreen
Winter in Montreal, Laval, Longueuil, and the North and South Shores can be relentless. Snow blankets the rooftops, and cold air seeps into every corner of your home. This is when the reliability of your CVAC system becomes crucial. Recently, AirGreen responded to a service call to repair a Trane heat pump in Ville-Marie. This particular case allowed our technicians to showcase not only their expertise but also the importance of maintaining high-quality equipment in such demanding conditions.
Service Background: A Trane heat pump under the snow
When a customer contacted us about their Trane heat pump installed in a Ville-Marie building, the problem initially seemed straightforward. It was cold, snow was piling up around the outdoor unit, and the system was no longer providing heat effectively. This type of issue is relatively common during the winter months when snow and ice accumulate on the outdoor units, affecting their performance.
Problems identified by our technicians
One of the most common causes of failure in these situations is the accumulation of snow or ice on the internal components of the outdoor unit, blocking air flow and impacting the system's performance. After a thorough inspection, our technicians discovered that the Trane heat pump in question had accumulated snow and ice, which was blocking the necessary airflow for operation.
Furthermore, a more in-depth analysis revealed that the issue wasn't solely related to the external environment. One of the air filters was clogged, restricting the unit's ability to function optimally. Due to the high humidity outside, the heat pump had also accumulated debris that was impairing its energy efficiency.
Solutions provided by AirGreen
To resolve these issues, AirGreen's team of technicians implemented a series of solutions:
-
Snow removal and defrosting of the outdoor unit: Our experts began by clearing the snow and ice accumulated on the Trane heat pump. Careful snow removal is essential to prevent damage to the internal components of the outdoor unit.
-
Cleaning the air filter: The clogged air filter was removed and thoroughly cleaned, which helped improve airflow through the unit.
-
Checking the defrost system: Our technicians then inspected the defrost system to ensure it was working properly, which is critical to prevent ice buildup on the outdoor unit during freezing temperatures.
-
Recalibrating settings and performance testing: After cleaning and repairing the unit, we conducted rigorous tests to ensure that the Trane heat pump was operating efficiently, particularly to provide consistent heat despite the low outdoor temperatures.
Outcome of the intervention: Restoring comfort for the customer
Thanks to the prompt and professional intervention of our technicians, the customer was able to enjoy optimal comfort in their home once again. Not only was the Trane heat pump repaired, but its efficiency was also improved, thus reducing the unit's energy consumption. The system resumed its crucial role: maintaining a comfortable indoor temperature, even during the coldest days of Montreal’s winter.

What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.

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.
