You remodeled the kitchen last summer. New cabinets, new flooring, two weeks of dust in the air. Ever since then, the furnace has been blowing something different—a faint, almost imperceptible smell, but it’s definitely there. It’s in your ducts, and it won’t go away on its own.
Duct Cleaning in Rosemont: Why It Matters Here
Rosemont is a neighborhood of duplexes and triplexes built between the 1920s and 1950s. These are solid, well-maintained buildings, often purchased and renovated by families who settle there for the long term. But behind the freshly renovated walls and sanded hardwood floors, the ventilation systems often date back several decades. Galvanized sheet metal ducts that have never been inspected since the forced-air heating system was installed.
Vortex Air has been working in this type of building for over a decade. Mohamed and Omar are familiar with the typical layouts of old Montreal apartment complexes—the ducts that wind between units, the makeshift connections added during a renovation in the 1980s, and the air vents that were repainted without ever being opened. Their INVC-certified technicians have already serviced more than 500 homes in the Greater Montreal area, and they know exactly what to look for in a home like yours.
The area’s urban density also plays a role. Major thoroughfares like Masson and Beaubien see a lot of traffic, and fine particulate matter finds its way into homes. Combined with dust from frequent renovations in this ever-changing neighborhood, it ends up in your ducts—and in the air your family breathes every day.
What We Clean at Your Home in Rosemont
Cleaning ventilation ducts
This is the service that has the most immediate impact on the indoor air quality in your home. We treat the entire system—from the main ducts to the air vents in every room—using a negative-pressure vacuum system and HEPA filters. We remove accumulated dust, allergens, mold spores, and construction debris that have built up over the years. You’ll notice the difference within the first few days.
Cleaning a wall-mounted unit (heat pump / wall-mounted air conditioner)
Many homeowners in Rosemont have installed wall-mounted units in recent years to manage summer heat in apartments that lack central air conditioning. These units quickly accumulate dust, biofilm, and mold inside the fins and the condensate pan. We disassemble the unit, clean each component, and restore it to a clean, working condition.
Dryer Vent Cleaning
In duplexes and triplexes, the dryer duct often passes through several walls before reaching the exterior vent. That’s where lint accumulates—not in the visible filter, but inside the duct itself. A clogged vent reduces the dryer’s efficiency, increases drying times, and poses a real fire hazard. Check the entire length of the vent and make sure the exhaust is clear.
Cleaning of an Energy-Recovery Ventilator (ERV / Air Exchanger)
The Air Exchanger It refreshes indoor air while recovering heat—but its filters and heat exchange cores gradually become clogged. When not maintained, it circulates stale air rather than purifying it. The internal components are cleaned according to the manufacturer’s specifications to restore efficient air exchange.
Cleaning of the Central Heat Pump and Central Heating System
For homes that have switched to a central heat pump, Regular maintenance of the coils, drain pans, and duct connections is essential to maintain the system's performance and prevent moisture problems in the ducts.
Furnace cleaning
Visit furnace Over the course of the seasons, combustion residues and dust build up on its internal components. Cleaning it before winter improves energy efficiency and reduces odors at startup, and helps detect potential problems before they turn into breakdowns in the middle of January.
Bathroom Fan Cleaning
A bathroom fan A clogged exhaust fan no longer removes moisture properly. In homes built in the 1940s and 1950s, this quickly leads to condensation on the ceilings and mold in the corners. We’ll take it apart, clean the motor and the exhaust duct, and make sure the exhaust fan is working as it should.
Decontamination
If an inspection reveals active mold in the ducts—which can occur after water damage or in a home that has been poorly ventilated for a long time—we perform a certified antimicrobial treatment. This service is not offered as a matter of course, but when it is necessary, we perform it properly using approved products.
Odor Control
Persistent odors—such as those from cigarettes, pets, dampness, or old buildings—that don’t go away with cleaning often originate in the ductwork. These odors are neutralized at the source, within the ventilation system itself, rather than being temporarily masked on the surface.
Complete system inspection
Before each service call, we perform a complete inspection of your ventilation system. We assess the condition of the ducts, appliances, connections, and vents. This is included in the inspection—at no extra charge. You’ll know exactly what you’re dealing with before we start anything.
Why Rosemont Residents Choose Vortex Air
The first thing people notice is that Mohamed and Omar show up on-site themselves. Not some unknown subcontractor sent by a franchise. Not someone who reads your address off a tablet and has never seen a building like yours before. The business owners themselves do the work or supervise it directly—and that makes a difference in the quality of the work.
The visit always starts with a free inspection. We take a look at your system, explain what we see, and provide you with a clear estimate before we touch anything. If your ducts are in good condition, we’ll tell you—no one here is going to make up a problem just to get a job. The price on the estimate is the price on the invoice, with no hidden fees along the way.
Vortex Air’s technicians are INVC-certified, and the company is in the process of obtaining NADCA accreditation—both of which are recognized standards in the residential ventilation industry in Canada. These aren’t just certifications to hang on the wall for show: they provide a framework for cleaning protocols and ensure that work is performed in accordance with industry standards.
We are available Monday through Sunday, from 7 a.m. to 9 p.m. The hotline is staffed 24 hours a day. In a neighborhood where landlords often have to manage tenants in addition to their own units, this flexibility isn’t a luxury—it’s a practical necessity.
Frequently asked questions
How often should the ducts in a duplex in Rosemont be cleaned?
The general recommendation is every 3 to 5 years for a typical home. In a duplex or triplex that has undergone recent renovations, or where the ducts have never been cleaned since purchase, we suggest not waiting until the next theoretical due date. A free inspection will let you know exactly where you stand.
What happens during a Vortex Air service call at my home?
We start with a free visual inspection of the system. We explain what we’ve found, provide you with a clear estimate, and wait for your approval before beginning. The service call itself usually takes between 2 and 4 hours, depending on the size of the network. We protect floors and furniture, use a negative-pressure HEPA vacuum, and leave without making a mess.
Does duct cleaning really help with allergies?
Yes, in practical terms. The ducts act as a reservoir for allergens—dust mites, mold spores, pet dander, and fine particles—which are released back into the air every time the system starts up. Cleaning the ducts removes this reservoir at the source. People with allergies and asthma often notice a noticeable difference in the weeks following the cleaning.
What's the difference between your cleaning service and a low-cost «express cleaning» service?
A thorough cleaning covers the entire duct system using negative-pressure suction—from the furnace or heat pump all the way to each air vent. An express cleaning typically cleans only the visible grilles and nothing else. At Vortex Air, we don’t do partial cleanings: we either clean the entire system or we don’t do it at all.
Do you also work in rental buildings and multi-unit properties?
Yes, and that’s a big part of what we do in Montreal. Whether you’re an owner-occupier of a duplex on De Lorimier or a manager of several units in the area, we adapt to the layout of each building. We can set up a maintenance schedule for all the units if you manage multiple properties.
What is the approximate cost of duct cleaning?
Without seeing your system, we can’t give you an honest estimate—and we’re wary of companies that quote a flat rate before even inspecting the building. What we can guarantee: the inspection is free, the estimate is clear and comprehensive, and there are no additional charges during the project. Our rates are competitive with industry standards.
What exactly is INVC certification?
The INVC (National Institute of Ventilation and Air Conditioning) is the professional certification body for ventilation technicians in Quebec. An INVC-certified technician has received recognized training and follows standardized protocols when performing service calls. This is a distinction that is not universal in the industry—not everyone who advertises duct cleaning services can claim this certification.
Does Vortex Air serve the entire Rosemont–La Petite-Patrie area?
Yes, the entire neighborhood is covered—from the streets around Maisonneuve Park to the shopping districts of Petite-Patrie. If you’re on the border with a neighboring neighborhood like Villeray or Plateau, call us at 514-214-7492 and we’ll confirm availability for your specific address.
