What duct cleaning cost starts at
Here’s the honest version of a price table. Two of these three lines have a real starting number. The third doesn’t. I’d rather tell you that than make one up.
| Job | Starting price |
|---|---|
| Duct or dryer vent inspection | $59, credited to the job if you proceed |
| Dryer vent cleaning | from $150 |
| Air duct system cleaning | priced on site after the inspection, no flat number |
The dryer vent line has a real floor because it’s almost always one run to one termination point, so I can quote it before I’ve seen the house. A full duct system doesn’t work that way, which is the same reason I can’t put a flat number on general HVAC duct cleaning up front either. A twelve-vent single story and a thirty-vent two-story with two returns aren’t the same job. Pricing them off the same number is exactly the trick I’m warning you about below. If you want every starting price I run in one place, the numbers are on the pricing page, laid out by job instead of buried in a paragraph.
Call (916) 833-2959 and ask for the $59 inspection. It’s the only way any of this turns into a real number for your system, and it comes off the job if you decide to move forward. I run that line myself, seven days a week, 7am to 7pm. If a musty smell or pet dander is the actual complaint rather than visible dust, that’s a different job. I price air duct sanitizing in Sacramento separately, at the same inspection.
What actually moves the price
Four things decide what a duct job costs once I’m standing in front of the system, and none of them are guesswork on my end.
- Run count: more vents and returns means more time sealing, agitating, and vacuuming each one.
- Layout: attic-run flex duct is faster to reach than duct buried in a crawlspace or a slab chase.
- Number of systems: a zoned two-story house often runs two separate air handlers, not one, and that’s two systems to seal and clean, not double the vents.
- Condition: a normal dusty system costs less time than one with a rodent nest, drywall dust from a remodel, or a collapsed flex run that has to get fixed before cleaning does anything.
That third one surprises people more than the others. A homeowner comparing a quote for their single-story ranch against a neighbor’s two-story bill assumes they’re being overcharged. Usually they’re not. Two air handlers means two trunk lines, two sets of registers, and two separate jobs of sealing and vacuuming under one roof. Vent count matters, but which system layout the house actually has moves the number more than people expect.
Air duct cleaning prices: why the $49 ads aren’t real
Search “duct cleaning near me” and half the results are a flat $49 or $99 for the “whole house.” That’s the bait. NADCA, the industry group that sets the standard for this trade, has warned for years that ads like that, often around $99 or $199 for a whole-house cleaning, usually cover a fixed number of vents, not the whole system. Everything past that number becomes an add-on once the truck’s already in the driveway.
Here’s the mechanism. A flat-rate ad has to price for the cheapest possible house to make the number work: a one-story, one-system, ten-vent home with easy attic access. Your house probably isn’t that house. So the tech shows up and counts your actual vents and your actual system. The $49 becomes $250 in add-ons before he’s touched a single duct, priced per vent after you’ve already let him in the door.
It’s not a scam exactly. It’s a number built for a house that isn’t yours. I don’t run flat-rate ads. Every quote here is priced per system and per vent, after the $59 inspection, so the number on the phone and the number on the invoice are the same number.
How ours compares
I’m not the cheapest name that turns up in a search for duct cleaning cost. I’m not trying to be. A flat $49 special will always beat a real per-system quote on the page. What it doesn’t include is the inspection that tells you whether your house is the cheap one the ad was built for.
It’s priced per system instead of guessed over the phone. The rest is priced on site, after someone has looked at it.
When you don’t need this
Most homes here don’t need duct cleaning on a fixed yearly schedule. Not every year, not even close. NADCA’s own guidance puts the interval at three to five years for a typical house, and for most people that’s about right. Dust builds up slowly, and paying to clean a system that wasn’t dirty enough to matter yet is money spent on nothing.
The exceptions are specific. A remodel that ran drywall dust through the returns for a month. A rodent that got into the attic and used a run as a nest. Wildfire smoke that sat in the house for weeks last August and settled into every low point in the flex duct. New construction, where the ducts sat open on a job site before drywall went up.
Any one of those moves the clock up regardless of when the system was last cleaned. Check the filter first. If none of that applies and the house just feels dusty, the fix is usually a furnace filter changed on schedule, not a duct cleaning. I’ll say so at the $59 inspection instead of selling you a job you don’t need.

Paying for it
A $150 dryer vent cleaning is easy. Most households just pay it and move on. A full duct system, once it’s priced per system and per vent, can land higher, especially on a two-story house with two air handlers.
If it lands closer to a full-system job, the rest is priced on site after the inspection. You can get on the calendar before the cold snap, and I’ll fold the $59 inspection into the work if you proceed.
Duct cleaning cost FAQs
These are the questions I get asked most before someone books a duct job.
How much does air duct cleaning cost?
There’s no flat number for a whole system, because it’s priced per vent and per system, not off a square-footage guess. A dryer vent cleaning starts at $150. A full duct system gets priced at the $59 inspection once I’ve counted the runs and seen the layout, not before.
Why won’t you just give me a number over the phone?
Because a phone guess turns into an argument about the final bill once I’m actually in the attic. Run count matters. So does system count and access. Together they change the price more than anything I could estimate blind. The $59 inspection removes the guessing, and it costs nothing extra if you go ahead.
Is a $49 or $99 duct cleaning special ever real?
The ad is real. It’s usually built for a smaller house than yours, though, and it prices per vent past a set number once the tech is already inside. A per-system quote after an inspection ends up more predictable, even when the number on the page looked bigger going in.
Does the $59 inspection cost extra if I book the cleaning?
No. It’s credited straight into the job if you go ahead, so you’re not paying for the inspection and the cleaning separately. You only pay the $59 on its own if the inspection turns up nothing worth doing, or you decide not to proceed with the work.
Why does a two-story house cost more than a one-story with more vents?
Usually because it has two air handlers instead of one, not because it has more vents. Two systems means two trunk lines, two sets of registers, and two separate jobs of sealing and vacuuming under one roof. That moves the price more than vent count by itself.
Does duct cleaning cost change if I add sanitizing?
Yes, that’s priced separately. It’s a different job from cleaning, not a step included in it. If the complaint is a musty smell or pet dander rather than visible dust, air duct sanitizing in Sacramento treats the system after cleaning, and I’ll price it at the same inspection.
How much should duct cleaning cost per vent?
There’s no flat number, because two vents on a short trunk line cost less than two vents split across separate returns and supply runs. I count every register and return during the $59 inspection, then price the whole system at once. Layout moves the total more than vent count alone.
Is the $49 duct cleaning special a scam?
Not a scam exactly, more a bait price. That $49 usually buys one vent or a bare diagnostic, and the tech upsells the rest once he’s already inside your ducts. I skip that model entirely. The $59 inspection is the whole cost of getting a real look, and it’s credited into any work you approve.
Why is air duct cleaning so cheap sometimes?
Sometimes it’s honest. A small single-story home with one return and short duct runs is a faster job than a two-story with a maze of trunk lines, and access matters more than most people think. But if a price undercuts everyone else by half, it’s usually covering less system than you think it is.
Booking it
The $59 inspection is the only way to turn any of this into a real number for your house. Call (916) 833-2959 and ask for it, or if you already know you want it, get on the calendar before the cold snap while a slot is still open. I run the schedule myself, seven days a week, 7am to 7pm, and the $59 comes off the job the moment you decide to move forward.
