About our air duct cleaning & sanitizing service

Most 'duct cleaning' outfits vacuum a couple of registers and leave. We follow NADCA source-removal standards: negative-pressure the trunk, agitate every branch line, and vacuum debris directly out of the system with HEPA-filtered truck-mount equipment. Antimicrobial sanitizing is optional after the cleaning is complete, never before.

Duct cleaning is worth doing when there is a real reason: a renovation that filled the returns with drywall dust, a rural property near Baxter or Minesing pulling in field dust every spring, rodent activity in a crawlspace, or a newly purchased home where nobody knows the history. We use NADCA-standard negative-pressure equipment and photograph the interior before and after, so you can see what came out rather than take our word for it.

What's included

  • NADCA source-removal method
  • HEPA-filtered truck-mount equipment
  • Every supply, return, and trunk cleaned
  • Optional EPA-registered antimicrobial sanitizing

Where we provide air duct cleaning & sanitizing

Innisfil is home base, and our trucks run the same routes daily across Simcoe County and north York Region.

  • Barrie Barrie's older downtown and Allandale homes leak air at the envelope but not at the ducts, which is exactly the combination that leaves upstairs rooms stale.
  • Bradford West Gwillimbury Marsh soil and farm activity around Bradford push a lot of fine dust indoors, and filtration there earns its keep every spring.
  • Essa Rural Essa properties on well water and gravel roads deal with grit that a one-inch filter simply cannot hold.
  • East Gwillimbury Newer Queensville and Sharon homes are sealed tight enough that mechanical ventilation is the only thing keeping indoor humidity in range.
  • Springwater Wood heat is still common through Elmvale and Hillsdale, and combustion particulate is the main air-quality concern we address there.
  • Newmarket Allergy complaints in Newmarket peak with the spring pollen load, and a properly sealed return does more than any add-on filter.
  • Oro-Medonte Walk-out basements and lakeside crawlspaces across Oro-Medonte drive the summer humidity problems homeowners call us about.
  • New Tecumseth Alliston's mix of farmland and industry means both pollen and fine particulate, so we usually spec media depth over gimmick features.
