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.
An Essential Service Call for the Proper Functioning of an Air Conditioning System in Winter
At AirGreen, we understand the importance of optimal thermal comfort, especially during extreme cold periods. Recently, our technicians responded to a service call in the Ahuntsic-Cartierville neighborhood of Montreal for a repair of an Elios wall-mounted heat pump. This intervention highlighted the importance of regular maintenance and professional assistance to resolve performance issues, particularly during extreme weather conditions.
Problems Encountered: Accumulation of Snow and Ice Around the Outdoor Unit
The Elios wall-mounted heat pump's outdoor unit was obstructed by a significant accumulation of snow and ice, as shown in the picture. This situation is particularly common in areas like Montreal, where winters are harsh, and snowfall is abundant. In fact, the accumulation of snow on outdoor units can seriously hinder the performance of heating and cooling systems.
In addition to the physical obstruction, snow and ice can lead to air circulation problems, making the outdoor unit ineffective. This can not only cause heating breakdowns but also damage internal components if not addressed promptly. Upon our visit, our technicians quickly diagnosed the situation.
Diagnosing and Solving the Problem: A Professional Intervention
Our technicians first proceeded with a complete snow removal from the outdoor unit. They cleared all accumulated snow and ice, restoring air circulation and preventing further complications. Once this step was completed, they inspected the other system components to ensure that the snow removal had not caused additional damage.
Several points need to be checked during such interventions:
-
Compressor Check: The compressor was functional, but it was important to ensure that no ice had affected its performance.
-
Refrigerant Line Inspection: The accumulation of snow around the refrigerant lines could affect heat transfer. Our technicians checked everything to ensure optimal performance.
-
Filter Check: While this wasn't the primary issue, our experts also cleaned the filters to improve the overall efficiency of the unit.
Preventive Maintenance and Advice: Preventing Future Breakdowns
During this intervention, our technicians also took the opportunity to provide practical advice to the homeowners to prevent similar incidents in the future. Regular maintenance of your wall-mounted heat pump is essential to ensure its proper functioning throughout the year, especially during intense cold spells.
Here are some tips for effective maintenance of a wall-mounted heat pump:
-
Regularly clear the outdoor unit of snow: During heavy snowfall, it is crucial to check that the outdoor unit is not obstructed by snow or ice.
-
Check the filters: Clean the filters of your heat pump every 3 to 6 months to avoid dust buildup and maintain optimal airflow.
-
Conduct annual inspections: An annual maintenance check by a professional helps detect potential issues before they become serious.
