Short answer: Choose a local, insured company that will tell you up front what’s included, cleans the full system with strong vacuum suction, and will show you any problem it says it found. Avoid $99 whole-house offers, high-pressure sanitizer upsells and anyone who claims duct cleaning will cure allergies.
Questions to ask before you hire
- What’s included? Supply lines, return lines, trunk lines and registers should all be part of it.
- How do you clean? Look for strong vacuum suction with tools that loosen the dust, so it’s removed, not stirred up.
- What will it cost for my home? A real answer depends on your home’s size, systems and vents.
- Are you insured?
- Will you show me what you find? The EPA suggests asking to see any contamination a company says it found.
Red flags
- $99 whole-house offers. The price usually climbs once they’re inside.
- Claims that duct cleaning cures allergies or prevents illness. The EPA says that’s never been shown.
- Pressure to buy sanitizers or sealants. The EPA says there isn’t enough research on these.
- Mold claims without proof. Ask to see it.
- A crew that only vacuums at the registers.
Get more than one opinion
The EPA recommends getting estimates from at least three companies. It’s also worth reading recent reviews from people in your area, not just the star rating.
How we work
We use a powerful HEPA-filtered vacuum and air-powered agitation tools to pull dust and debris out of your supply lines, return lines and main trunk lines, and we clean the registers and grille covers. The dust ends up in our equipment, not your home, and our crew wears boot covers inside. Most air duct cleaning jobs we do run about $1,500 to $2,500, priced from your home’s size, how many furnaces or systems you have, and how many supply and return vents there are. If your system doesn’t need cleaning, we’ll tell you. We’re a family-owned, insured company based in Underhill, and we stand behind the work we do.
