Does your home or office still smell funny even after you've cleaned? The smell keeps coming back and you don't know what to do?
The problem is probably due to your ventilation system which spreads bad odors everywhere.
Where do these stubborn odors come from?
Common sources in residential ducts
- Hidden mold that thrive in humidity
- Animal waste (mice, squirrels, bats)
- Dust accumulation mixed with moisture
- Kitchen odors embedded in the system
- Cigarette smoke absorbed by the ducts
- Pet fragrances concentrates
Problems specific to commercial buildings
- Industrial chemicals that accumulate
- Restaurant odors in shared systems
- Building materials fumes recent
- Commercial cleaning residues that mix
Our 5-step elimination process
1. Diagnosis by olfactory and visual inspection
Our technicians identify the exact source with professional odor detectorss and a endoscopic inspection camera.
2. Complete mechanical cleaning
We physically remove all odour-trapping residues: encrusted dust, animal debris, greasy build-up.
3. Specialized neutralizing treatment
Application ofbiological enzymes which break down odour-causing molecules at source.
4. Controlled ozone deodorization
Our industrial ozone generator oxidizes odor compounds at the molecular level (used only when safe).
5. Long-lasting odor protection
Spraying a antimicrobial coating which prevents new odors from taking hold.

Emergency situations requiring rapid intervention
After death of animal in system
The smell of decomposition spreads rapidly throughout the building. The longer you wait, the harder it is to eliminate completely.
Sewer back-up in ducts
When drainage systems fail, sewer odors rise through the ventilation. This poses an immediate health risk.
Smoke damage after fire
Fine soot penetrates everywhere in the flues. Without professional treatment, the burning smell lingers for years.
Recent rodent infestation
Pheromones and animal urine create odors that attract other pests. The cycle must be broken quickly.
Preventing recurring odors
Humidity control
Maintain less than 50% relative humidity to prevent microbial growth that causes musty odors.
Regular filter changes
Clogged filters trap odor particles that eventually contaminate the entire system.
Annual preventive cleaning
Regular maintenance prevents the build-up of residues that later become sources of stubborn odours.
Duct sealing
Leaks allow external odors to infiltrate (sewers, damp basements, storage spaces).
Vortex Air anti-odour guarantee
60-day satisfaction guarantee
If odours return within 60 days, we come back free of charge for further treatment.
Certified olfactory test
Our technicians document the entire removal process with olfactory neutrality tests before considering the job finished.
30-day telephone follow-up
We'll call you back a month later to make sure everything's going well and answer any questions you may have.
Estimated disposal costs
Prices depend on several factors:
- Odor typeOrganic odors are more complex to treat
- Allocated areaComplete house vs. just a few rooms
- Contamination intensity: Measured by our specialized detectors
- Exposure time: The older it is, the more treatment it requires
- Accessibility: Some pipes are more difficult to treat
On average, odour elimination costs 20-30% more than standard cleaning, but 70% less expensive than to change the whole system.

Frequently Asked Questions About Eliminating Persistent Odors in Quebec
Why does my house still smell bad even after a thorough cleaning?
Because, in many cases, the odor doesn’t come from visible surfaces. We’ve seen this often in the field: everything is clean, but as soon as the ventilation kicks in, the odor returns. That means the odor is embedded in the ducts. The system acts like an odor dispenser and spreads it everywhere, no matter how many times you mop the floor.
How can you tell if the odor is really coming from the ventilation system?
A clear sign is when the odor gets stronger when the heat or air conditioning is running. Another clue: the odor seems to be coming from several rooms at once. During our inspections, we often discover damp areas, caked-on dust, or animal droppings that no one suspected were there until we looked inside the ducts.
In practice, which odors are the hardest to eliminate?
The worst odors you’ll encounter are animal urine, rodent pheromones, decomposing animal matter, and stale cigarette smoke. These are odors that penetrate deep into materials. If someone promises to fix this with just a perfume, be wary. These odors need to be chemically neutralized, not masked.
Why do air fresheners and perfumes sometimes make the situation worse?
Because they just add another layer on top of the problem. We often walk into homes where the air smells like a strange mix of artificial fragrance and the original odor. The result: it becomes heavier, more stifling. As long as the molecule responsible for the odor is there, it always ends up coming back.
How do you identify the actual source of the odor before treating it?
It comes down to experience. A musty smell can come from a poorly insulated duct, a condensation pan, or an invisible leak. We combine inspection olfactory sensors, cameras, and humidity analysis. Treating the problem without identifying the exact source is one of the most common mistakes we see in poorly executed treatments.
Is cleaning alone enough to eliminate stubborn odors?
No, not always. Cleaning removes physical residue, but some odors remain embedded in surfaces. That’s where enzymes and neutralizing treatments come into play. We’ve often seen cases where cleaning alone improved the situation… but where the odor returned a few weeks later because a deep treatment wasn’t performed.
Is ozone dangerous, or is it effective against odors?
Both, depending on how it’s used. Ozone is very effective at oxidizing odors that nothing else can eliminate, but only when used in a controlled manner with professional equipment. If used improperly, it can cause problems. When used properly, it’s sometimes the only solution that actually works.
How long does it take to see real results?
Often, the difference is immediate. In more severe cases, it can take a few hours or a full day. What matters is how long the results last. If the odor goes away and doesn’t come back, the job was done right. If it comes back, it means a source was overlooked.
In what situations should you take immediate action?
After an animal dies in the system, a sewer backup, or smoke damage, you need to act quickly. The longer you wait, the deeper the odors penetrate the pipes. We’ve seen cases where a delay of just a few weeks made the treatment twice as difficult.
How can you prevent odors from returning after they've been eliminated?
Humidity control is essential. A house that’s too damp will eventually start to smell musty. In addition, filters must be changed regularly, and ducts must be airtight. Even a small leak can draw in odors from the basement, the sewer, or storage areas without anyone noticing.
Is it more cost-effective to eliminate odors or to replace the system?
In most cases, professional removal is much less expensive than replacing the entire system. Replacement is recommended only when the materials are too damaged. People often think everything is lost, when in fact proper treatment can solve the problem for a long time.
How can you tell if the odors have really been eliminated?
When the air becomes neutral. Not scented, not masked—just normal. A job well done is when you forget there was ever a problem. And most importantly, when the professional remains available if an odor reappears, instead of disappearing after payment.
