About Our South San Francisco, CA Air Quality Technicians

The "Hidden Danger" in Your HVAC System


Wildfire smoke isn't like regular dust. It's a toxic mix of fine particulate matter, soot, and ash.

  • It Gets Trapped: Your HVAC system pulls this air in, and the particles settle in your ductwork.
  • It Recirculates: The next time your AC or heat kicks on, it "wakes up" these particles and blasts them into your living space.
  • It's a Health Risk: This particulate matter is a known respiratory irritant, triggering asthma, allergies, and other health issues.

When Should You Clean Your Ducts?


  • After a nearby wildfire (even if you just smelled smoke for days).
  • If you see fine, dark dust (soot) settling on sills or surfaces.
  • If a "smoky" or "burnt" smell lingers, especially when the AC turns on.
  • If your family is experiencing new respiratory issues.

Our "Source-Removal" Cleaning Process


We use the only method approved by NADCA.

  • Agitation: We use high-powered, rotating brushes to scrub the inside of your ducts and dislodge all caked-on soot, ash, and dust.
  • Extraction: We connect a massive, truck-mounted HEPA vacuum to your system. This creates negative pressure, pulling all the dislodged contaminants out of your home and trapping them.




Frequently Asked Questions


  • Will changing my filter be enough? No. Your filter only protects your HVAC unit. It does not clean the 200+ feet of ductwork where the contaminants have already settled.
  • What is NADCA-certified? It's the "gold standard" from the National Air Duct Cleaners Association. It's your guarantee that we are trained, insured, and will not be a "bait-and-switch" scam.
  • Is this a long, messy process? No. A professional cleaning takes 2-4 hours, and we guarantee "no-mess." Our system ensures all dust is contained.
  • Will this help my allergies, too? Absolutely. The same process that removes smoke and soot also removes the pounds of dust, pollen, and pet dander that cause everyday allergies.
