Nobody wants to have people over when their house is a mess, but it seems many people don’t just worry about how their house looks; they also worry about how their home smells. No wonder Canadians invest heavily in scented candles, diffusers and air fresheners. According to some statistics, the Canadian air freshener market is expected to reach $145 million by 2028. But while finding a solution, homeowners often ask if duct cleaning can remove the smell.

Types of Bad Odour in Home

Before we explore whether duct cleaning can eliminate unpleasant odors, let’s first understand the common types of bad smells that can linger in a home:

• Mold and Mildew

Moisture and dark corners can cause mold growth. This growth gives a musty odor that is both unpleasant and potentially harmful to health. When hypersensitive people inhale mold, it can trigger asthma and other allergy symptoms.

⦁ Pet Odors

Our furry friends bring joy to us, but they can also leave behind odours from fur, dander and pet waste. These elements can get stuck in the vents and hence affect the air quality.

⦁ Sewage Smell

A sewage odor coming from your air vents usually indicates a problem with your home’s plumbing. It is commonly due to a clogged drain or sewer line that needs cleaning.

⦁ Tobacco Smoke

Smoking indoors can leave a persistent smell that is challenging to eliminate, affecting both air quality and the overall atmosphere.

⦁ Stale Air

Poor ventilation and stagnant air can create a general staleness that does not necessarily have a specific source but still affects the overall perception of home freshness.

⦁ Attic Smell

Gaps in your ductwork may cause an attic smell to emanate from vents as musty air and odors are drawn into the ductwork through those entry points. Inspect your ducts for leaks, holes and other signs of damage.

Can Duct Cleaning Remove the Odor?

Now, let’s address the main question: Can air duct cleaning remove unpleasant smells from your home? Yes, it can. Here is how:

⦁ Removal of Accumulated Dust and Residue

Over time, dust, dirt and other residues can accumulate in your HVAC system. When air circulates through these ducts, it can carry these particles, and cause unpleasant odors. Professional duct cleaning will remove this buildup and prevent it from recirculating in your home, eliminating the bad odor.

⦁ Mold and Mildew Prevention

As mentioned earlier, mold and mildew can produce a musty smell in home. Duct cleaning removes existing mold and prevents its recurrence by applying antimicrobial agents to the duct surfaces. These agents help inhibit the growth of mold and mildew. Duct cleaning services also include fixing leaks, insulating ducts to prevent condensation and ensuring proper drainage.

⦁ Pet Dander and Hair Removal

If you have pets, their dander and hair can enter your HVAC system. Duct cleaning uses specialized equipment like a high-efficiency particulate air (HEPA) vacuum to effectively capture and remove these microscopic particles. This prevents their recirculation through the home, supplying cleaner and fresher air. This process reduces pet allergens, ensuring improved indoor air quality and minimizing the unpleasant odors your furry companions leave behind.

⦁ Tobacco Smoke Residue

Air duct cleaning can also remove the lingering effects of tobacco smoke. The particles from smoke can settle in the ducts, spreading the odor throughout the house. By cleaning the ducts, you can significantly reduce the presence of these particles and the associated smell.

⦁ Improved Air Circulation

Stale air can result from inadequate ventilation. Duct cleaning improves the overall airflow, making sure your home is filled with fresh, clean air. This method allows you to remove VOCs, MVOCs, allergens, odors and other fine particulate matter while also improving the well-being of your loved ones. This alone can make a noticeable difference in the perceived freshness of your living space.


In short, duct cleaning can keep your home smelling great. It tackles mold, pet dander, and other culprits that can make your house less inviting. While it will not solve every smell issue, it can resolve most underlying issues. For a complete freshness strategy, team up duct cleaning with other odor fighters.
