Duct Cleaning in Vancouver
Duct cleaning is one of the more aggressively marketed services in this industry, and the honest position is that it genuinely helps in specific situations and is sold far more often than those situations occur. Knowing which you are in saves you money.
When cleaning actually helps
Clear cases: visible mould inside ducts or on the air handler, evidence of rodents or insects nesting in the system, ducts genuinely clogged with debris to the point of restricting airflow, and after construction or renovation work that has put drywall dust through the system.
Also worth it when a system has been open during a major renovation, or in a house you are buying where the history is unknown. What it is not is a routine annual necessity — guidance from Health Canada and the US EPA has consistently been that there is no evidence routine duct cleaning prevents health problems in an otherwise clean, dry system.
What a proper clean involves
Proper cleaning uses a high-powered vacuum connected to the system to put it under negative pressure, with agitation — brushes or compressed air tools — working debris loose to be carried away. Every supply and return register is done, plus the main trunk lines and the air handler itself.
It should include the blower compartment and coil, because that is where the most consequential build-up sits. A crew that vacuums the visible part of each register with a shop vac in twenty minutes has not cleaned your ducts. Ask what equipment is used and whether the air handler is included before booking.
Frequency claims vs. evidence
Marketing commonly suggests every two to three years. There is no evidence base for that interval; it exists because a recurring schedule is a better business model than an as-needed service.
Be wary of unsolicited calls offering whole-house duct cleaning at an implausibly low price. It is a long-running bait pattern: the advertised price covers a token effort and the real quote arrives once a crew is in your basement. A reputable operator will happily tell you if your ducts do not need doing, and for a well-maintained system with a good filter that is often the honest answer.
Post-renovation dust removal
This is the strongest genuine case. Drywall dust is fine, abrasive and gets everywhere, and if the system ran during construction — or returns were left open — it is now distributed through the ductwork and will come back out gradually for months.
The better answer is prevention: seal registers and returns during dusty work and do not run the system, then change the filter afterwards. Where that did not happen, cleaning afterwards is worth it and is one of the few times we would recommend it without reservation.
What this costs
$420–$780 service · heat pump installs $11,000–$24,000
Annual service and diagnostics are a fixed visit. Installs are quoted after a heat-loss assessment — an undersized system is a more expensive mistake than the price difference between quotes.
Materials are always separate from labour and passed on at cost. Quotes are free and written, and the full rate card is published rather than given out on request.
Common questions
Do ducts really need cleaning every few years?
No. That interval is a marketing convention rather than an evidence-based one — Health Canada and the US EPA have both long said there is no evidence routine cleaning prevents health problems in a clean, dry system. Clean when there is a reason: mould, vermin, genuine debris, or renovation dust.
Does duct cleaning help allergies?
Only where there is an actual contaminant in the ducts — mould, vermin or construction dust. For allergies generally, a better filter changed on schedule, controlling humidity and dealing with the source in the living space do far more. If a company promises allergy relief from cleaning alone, treat that as a sales claim rather than a medical one.
How long does it take?
A proper job on an average home is several hours, not forty minutes. It should cover every supply and return, the trunk lines and the air handler including blower and coil. If a crew is finished very quickly, they have vacuumed the register openings rather than cleaned the system.
