Restoring Comfort in Pointe-Claire: A Deep Dive into Our Lennox Central System Repair
At AirGreen, we pride ourselves on our dedication to quality HVAC repair and maintenance services across Montréal, Laval, Longueuil, Rive Nord, and Rive Sud. Each project we undertake is more than just a job; it’s an opportunity to reinforce our reputation for thorough, customer-centered service. Recently, we had the pleasure of servicing a Lennox central air system in Pointe-Claire, a project that highlighted our commitment to diagnosing and resolving issues from the root.
Understanding the Issue: Symptoms and Diagnosis
The client had reached out, describing symptoms of inconsistent air distribution and an unusually high energy bill, suggesting the central system might not be running efficiently. Upon arrival, our technician conducted a preliminary inspection, focusing on key components of the system, including the blower motor, electrical connections, and ductwork. This thorough approach is something we emphasize at AirGreen—it’s not just about getting the unit to run again; it’s about ensuring it operates as efficiently as possible.
Thorough Inspection: Locating the Core Issue
During our inspection, we identified that the humidifier attachment connected to the system was not functioning optimally, contributing to the discomfort in the home and inefficient operation of the entire system. This issue was coupled with some clogged filters and slight wear on the blower motor. It became clear that a comprehensive repair was necessary to restore the system to peak performance.
The Repair Process: Bringing the Lennox Central System Back to Life
-
Humidifier Repair and Calibration: Given the significance of the humidifier in maintaining a balanced indoor climate, we started by recalibrating it to ensure that it could effectively control humidity levels. A malfunctioning humidifier often leads to a dry or overly humid environment, so this adjustment was essential for comfort.
-
Blower Motor Tune-Up: Next, we addressed the blower motor, cleaning and lubricating its components to enhance its efficiency. Regular tune-ups for the motor help extend its lifespan, saving the customer from future costly replacements.
-
Duct Cleaning and Seal Check: Ducts can sometimes be overlooked in HVAC maintenance, but they’re critical for efficient airflow. We inspected the entire duct network, identifying minor leaks that could lead to energy loss. Sealing these leaks improved the system’s energy efficiency, contributing to lower utility bills.
-
Filter Replacement: We replaced all filters, as dirty or clogged filters are a common cause of reduced system efficiency. This simple step made a significant difference, ensuring better air quality and more effective airflow.
-
System Testing: Finally, we ran the system through a full-cycle test to ensure each component was working in harmony. This involved checking temperature consistency across all rooms and verifying that the system responded well to thermostat adjustments.
Going the Extra Mile: Customer Satisfaction at the Core
Once we completed the repairs, we didn’t just pack up and leave. Instead, we took the time to explain to the customer what had gone wrong and how our solutions would improve the system’s operation. Our technician highlighted routine maintenance tips to keep the system running smoothly. By involving the customer in the process, we empowered them with knowledge to prevent future issues.
The customer was delighted with our service, particularly our approach to identifying the root cause rather than just addressing the symptoms. This attention to detail and commitment to transparency is a cornerstone of our philosophy at AirGreen. For us, every service call is an opportunity to showcase our expertise and build lasting relationships with our clients.

Common Issues with Central Systems and How We Solve Them
Central HVAC systems, especially older models, can experience a range of issues. Here’s a look at some typical problems and how our expertise at AirGreen addresses them:
Inconsistent Temperature Control
Inconsistent temperatures in various parts of the home can be frustrating. We address this by inspecting ductwork for leaks and ensuring even airflow distribution. In this case, our duct sealing significantly improved temperature consistency.
High Energy Bills
An inefficient system often results in higher energy consumption. We focus on optimizing each component, from motors to filters, to enhance efficiency and help reduce costs.
Noisy Operation
Unusual noises can indicate underlying mechanical issues. Our inspection includes checking for loose components, worn belts, and other sources of noise.
Maintaining Your Lennox Central System for Longevity
Regular maintenance is key to ensuring the longevity and efficiency of your HVAC system. Here are some essential tips to keep in mind:
- Change Filters Regularly: Clogged filters reduce airflow, making the system work harder.
- Schedule Annual Tune-Ups: A professional inspection can catch issues before they become costly repairs.
- Check Humidity Levels: If your system includes a humidifier, ensure it’s properly calibrated to maintain optimal indoor humidity.
- Listen for Unusual Noises: These can be an early warning sign of mechanical issues.

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.
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
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. A central heat pump uses the house's ducts.
It connects to the existing ducts to heat and cool everywhere.
2. In extreme cold, electric backup heat can take over.
The indoor module (furnace or air handler) works with the heat pump and takes over in extreme cold.
3. The filter only gets changed when the unit breaks down.
A dirty filter cuts airflow. It gets checked regularly.
4. You can reuse the old unit's size without checking.
The house may have changed: insulation, windows, added rooms. Capacity is confirmed on site.
