How much does it cost to clean air vents and ducts?
Updated
Short answer
Cleaning the air vents and registers yourself costs $0 to $10, for a little soap, and takes 30 to 60 minutes for the whole house. A professional duct cleaning, which is a different and much bigger job, costs $300 to $700. Most homes never need the professional version. Washing the registers and vacuuming the first stretch of duct behind them is where the dirt is.
Cost breakdown
| Item | DIY | Pro |
|---|---|---|
| Materials | $0 to $10 | included |
| Tools you may need to buy | none | included |
| Labor | your time | $300 to $700 |
| Total | $0 to $10 | $300 to $700 |
The DIY cost is mild soap. The pro cost is a duct cleaning crew with truck-mounted vacuums and rotary brushes that run the length of every duct, which is a few hours' work and the reason the price is what it is.
What drives the cost
- The size of the duct system. Duct cleaners price by the number of vents and the length of duct, so a large house with many registers costs more.
- Access. Ducts in a crawl space or an attic, and a system with sections the crew has to cut into, add time.
- Add-ons. Sanitizing sprays, dryer vent cleaning and furnace cleaning are often offered alongside, and some are worth it and some are padding.
- Who you hire. Prices for duct cleaning vary widely, and the very cheap offers often come with a hard upsell once the crew is in the house. A fixed quote from an established company is the safer buy.
- Whether it's needed at all. A home with a filter that's changed on schedule rarely has dirty ducts, and a cleaning that isn't needed is the most expensive kind.
DIY vs. pro
For nearly every home, this is a DIY job. How often to clean air vents and registers is every 6 to 12 months, and the job is unscrewing the covers, washing them in the tub, and vacuuming as far into each duct as the hose reaches. That's where the dust is, and it costs nothing.
A professional duct cleaning earns its $300 to $700 in a few situations: after a renovation that left the ducts open to drywall dust, when you find mold or a dead animal in a duct, when a vacuum pulls debris rather than dust out of the first stretch, or in a house whose previous owners let the filter go for years. If none of those apply, keep the money and change the filter.
FAQ
How much does duct cleaning cost?
$300 to $700 for a whole house, from a crew with truck-mounted equipment. Cleaning the registers yourself costs $0 to $10.
Is professional duct cleaning worth it?
Rarely. It's worth it after a renovation, for mold or a pest problem in the ducts, or for a system that's been badly neglected. For an ordinary home with a clean filter, no.
How do I know if my ducts need cleaning?
Pull a register off and look. Dust is normal and the vacuum handles it. Debris, mold, or a puff of dust from the vents every time the system starts means a closer look.
Can I clean my own air ducts?
The registers and the first stretch of duct behind them, yes, with a vacuum. The full length of the ducts needs the crew's equipment, and usually doesn't need cleaning at all.
