Description of the Service Call and Repair Process:
At AirGreen, we are specialists in HVAC repairs and installations. Recently, our team had the opportunity to assist a customer in Boisbriand with a malfunctioning electric furnace, specifically the air handler. The customer reached out to us due to concerns about the unit's inefficiency and ongoing operational issues.
Identifying the Issue:
Upon arrival at the customer's home in Boisbriand, our technician conducted an initial inspection of the electric furnace air handler. The unit was housed in a basement utility room, surrounded by several bins and stored items, as shown in the picture. The space was quite compact, which presented a slight challenge in terms of accessing the furnace for proper diagnostics. However, our team quickly assessed the situation and identified a few key issues:
-
Dust and debris accumulation: The area surrounding the air handler was cluttered, which led to an accumulation of dust and dirt on the unit's filters. This blockage was restricting airflow, reducing the system's efficiency.
-
Poor air circulation: The unit was not circulating air as it should, likely due to a malfunctioning blower motor. This issue was affecting the furnace's ability to heat the home properly, and the customer was noticing uneven warmth throughout their space.
-
Age of the unit: The electric furnace itself was older and had not been properly maintained in recent years. This contributed to wear and tear on the components, which, if left unresolved, could lead to complete system failure.
The AirGreen Solution:
Our technician took immediate action to resolve these problems and restore comfort to the customer’s home:
-
Cleaning the filters: The first step was to clean the air filters and ensure that there were no blockages preventing airflow. We carefully removed the dust and debris that had built up around the unit, improving the overall air circulation.
-
Blower motor replacement: After confirming the issue with the blower motor, we recommended a replacement to restore proper air circulation. We used high-quality replacement parts to ensure long-lasting performance.
-
Maintenance check: Given the age of the unit, our technician performed a thorough maintenance check to identify any other potential issues. We lubricated moving parts, checked electrical connections, and ensured everything was functioning smoothly.
Final Outcome:
After completing the repairs and servicing the system, the electric furnace air handler was back to full functionality. The customer immediately noticed a significant improvement in airflow and heating efficiency. The home was warmer, and the system was running smoothly once again.

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.
It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
