Laval: a hotspot for ventilation failures when maintenance is neglected
During our HVAC maintenance service calls across Laval, our teams consistently encounter recurring mistakes that directly impact the performance of ventilation systems, increase energy consumption, and—most importantly—compromise indoor air quality. These errors, often the result of poor follow-up or a lack of understanding of how the systems function, can have serious consequences ranging from thermal discomfort to respiratory health problems.
1. Forgetting to clean the ducts: an invisible but ever-present danger
This is the most common and underestimated mistake. In several residential and commercial buildings in Laval, we’ve found:
-
Dust and pollutant deposits that had been accumulating for over 10 years
-
The presence of mold in ducts exposed to constant humidity
-
Persistent odours caused by trapped organic waste in the ductwork
A full duct cleaning every 3 to 5 years is essential. At AirGreen, we use industrial rotary brushes paired with HEPA vacuum systems to remove all contaminants effectively.
2. Neglecting filters: a dirty filter compromises the entire system
A clogged filter reduces airflow, puts pressure on the motors, and lowers the system’s overall efficiency. Yet, many property owners in Laval:
-
Forget to change their filters every 3 months, especially during peak heating or cooling seasons
-
Use low-quality filters, ineffective against fine particles (PM2.5)
-
Install incompatible models for their air handling units
We recommend using MERV 13 or HEPA filters, especially in urban areas of Laval that are exposed to high levels of outdoor pollution.
3. Ignoring ventilation system calibration: a hidden imbalance
Even when all components seem operational, a poorly balanced system results in:
-
Excessive suction in some rooms and lack of fresh air in others
-
Overheating of motors due to pressure imbalances
-
Overall system inefficiency, with cold or overheated zones
At AirGreen, we use digital manometers and professional anemometers to precisely measure airflow distribution and adjust each register according to the specific needs of every space.
4. Skipping annual inspections: a false economy
In Laval, many clients call our technicians only when there's a breakdown or strange noise. However, a simple annual preventive visit allows for:
-
Early detection of corrosion, loose parts, or worn motors
-
Optimized energy consumption, often reduced by 10% to 20% after adjustments
-
Prolonged system lifespan, by preventing major failures
We offer custom maintenance contracts, tailored for Laval’s single-family homes, plexes, and commercial buildings.
5. Forgetting exterior grilles: an open door for pests and dirt
Air intake and exhaust grilles are often neglected. Our technicians have found:
-
Bird nests completely blocking air intake
-
Dead rodents inside unprotected ducts
-
Rusty or broken grilles, allowing rain, leaves, or insects to get in
We recommend installing galvanized steel grilles with pest-proof mesh, resistant to weather and intrusion.
Real-life example: service call in a triplex in Chomedey, Laval
A landlord contacted us after tenants complained about poor air circulation and persistent bathroom odours. After inspection, we found:
-
A duct network clogged with debris
-
Filters that hadn’t been replaced in 4 years
-
An exterior grille completely blocked
Solutions implemented by AirGreen:
-
Complete duct and ventilation box cleaning
-
Replacement of filters with high-performance HEPA models
-
Replacement of the exterior grille with a secure model
Result: +65% improvement in measured air quality, and a return to optimal thermal comfort for all occupants.
