Is it really necessary to clean your air ducts? Myth or reality for residents of Laval

Optimizing indoor air quality through proper duct cleaning and ventilation maintenance

At AirGreen, we understand how important indoor air quality is for homes and businesses in Laval, just as it is in Montréal, Longueuil, on the North Shore and South Shore. Many of our clients ask us the same question: is it really necessary to clean the air ducts in their ventilation system, or is it just a myth perpetuated by the industry?

In this article, we’ll debunk common misconceptions and present the real-world facts we see every day during our HVAC service calls in Laval. Whether you’re a homeowner or a building manager, this article will help you better understand the importance of duct cleaning, its tangible benefits, the risks of neglect, and how AirGreen can support you with care and professionalism.

What you breathe matters: why your air ducts must stay clean

The air that circulates through your ducts carries more than just oxygen. Dust, dust mites, mold spores, pet hair, allergens, bacteria, and even outdoor pollutants can build up inside your duct network. This invisible cocktail can impact respiratory health, especially for children, the elderly, or those with asthma or allergies.

During our HVAC maintenance visits in Laval, we often discover clogged ducts, heavily soiled systems, or signs of excessive humidity promoting mold growth. This buildup, often invisible to the naked eye, can reduce your system’s efficiency, increase energy consumption, and harm your indoor comfort.

Is it really necessary to clean your air ducts? Here’s what we see in the field

Contrary to popular belief, duct cleaning isn’t a luxury—it’s a periodic necessity. At AirGreen, we generally recommend an inspection every 3 to 5 years, depending on the following conditions:

• Presence of pets in the home.

• Recent renovation work that generated dust and debris.

• Signs of mold or moisture.

• Older or poorly maintained systems.

• Persistent odors in certain rooms.

• Unusual allergic symptoms among occupants.

We recently performed a complete duct cleaning in a single-family home in Chomedey, Laval, where the owners had been suffering from chronic congestion for months. After our service, not only did the odors disappear, but the residents also noticed a clear improvement in their breathing comfort.

What are the real benefits of duct cleaning in Laval?

Cleaning your air ducts is not just a cosmetic maintenance task: it’s a strategic action that enhances the lifespan of your HVAC system and the well-being of your household.

Here are the most common benefits observed after an AirGreen service:

• Significant improvement in indoor air quality

• Reduction of airborne contaminants and allergens

• Optimized energy efficiency (your heat pump or furnace doesn’t need to work as hard)

• Less noise from air movement through dirty ducts

• Extended lifespan of your ventilation equipment

• Less frequent dusting throughout the home

We use specialized equipment, including inspection cameras, high-pressure industrial vacuums, and rotary brushes to clean the entire duct network, without damaging the system.

What you’re not being told: the risks of prolonged neglect

Neglecting your ducts can lead to:

• Mold buildup that may be harmful to your health.

• Excessive energy use caused by restricted airflow.

• Premature wear on your HVAC system.

• Persistent health problems (rhinitis, headaches, fatigue).

In a multi-unit building located in the Pont-Viau area of Laval, we recently had to intervene urgently after a dust-clogged duct caused the central system to overheat, producing a worrying odor and multiple tenant complaints. A swift intervention resolved the issue and restored the building manager’s peace of mind.
