Duct cleaning gets a lot of mixed press. Some companies oversell it as a magic fix for every home, while others dismiss it entirely. The truth, like most things in the trades, is more practical than either extreme.

Here’s an honest look at what duct cleaning actually does, when it’s worth doing, and when it isn’t.

What Is Duct Cleaning?

Duct cleaning involves clearing dust, debris, and buildup from the supply and return air ducts in your home’s HVAC system, along with registers, grilles, coils, and other components. It’s typically done using high-powered vacuum equipment and brushes to loosen and remove accumulated material.

When Duct Cleaning Is Genuinely Worth It

There are specific situations where duct cleaning makes a real difference:

• After a renovation. Construction produces fine dust and debris that gets pulled into your ductwork. If you’ve had work done recently without the HVAC system properly sealed off, a cleaning is a good idea.
• If you’ve moved into an older home. You don’t always know how well the previous owners maintained the system. A cleaning gives you a clean baseline.
• After a rodent or pest problem. If there has been any evidence of pests in your ductwork, cleaning is necessary.
• If visible mould is present inside the ducts. Mould growth in your HVAC system is a health concern that needs to be addressed.
• If the home has been vacant for an extended period. Dust and debris accumulate quickly in unused systems.

When You Can Probably Skip It

If your home is relatively new, you’ve been consistent with filter changes, and you haven’t had any of the situations listed above, your ducts are likely fine. The EPA and Health Canada both note that duct cleaning has not been shown to improve air quality in homes where there is no specific contamination issue.

Changing your furnace filter regularly (every 1 to 3 months depending on the type) does more for your air quality on an ongoing basis than periodic duct cleaning.

How Often Should Edmonton Homeowners Clean Their Ducts?

For most homes in Edmonton, every 3 to 5 years is a reasonable interval if you’re maintaining your filters and haven’t had any major renovations or issues. Homes with pets, allergy sufferers, or wood-burning features may want to look at it more frequently.

What to Watch Out For

Be cautious of companies offering extremely low flat-rate duct cleaning deals. These often involve basic equipment and rushed service that doesn’t do a thorough job, and sometimes lead to upselling for services you don’t need. Look for a licensed mechanical contractor who can also inspect your system while they’re there.
