How much does air duct cleaning cost?

Air duct cleaning costs $349 for a home with up to 10 vents, plus $19 for each additional vent. A typical 3-bedroom Bay Area house has 10 to 14 vents, so most homeowners pay between $349 and $425. The price includes all supply and return ducts, the main trunk lines, and washing the register covers.

We connect a negative-air vacuum to your main trunk line, seal the other openings, then work each supply and return run with air whips and rotary brushes so the dust moves toward the vacuum instead of into your rooms. The registers come off, get washed, and go back on. The collection drum gets opened in front of you.

Most Bay Area homes have ducts that were last touched when the house was built or when the furnace was replaced. Ranch homes from the 1950s to 1970s usually have sheet-metal trunks with flex-duct branches added later. Newer homes run flex duct through the attic. We clean both, and we tell you when we find crushed runs, disconnected joints or the kind of old cement-board duct that should be tested rather than agitated.

What's included

  • All supply registers and return grilles, removed and washed
  • Every supply and return run, agitated with air whips or rotary brushes
  • Main supply and return trunk lines under negative pressure
  • Vacuuming of the plenum boxes we can reach without cutting
  • Furnace filter check, with a note if it needs replacing
  • Floor and furniture protection, and cleanup of every register area
  • Photos of what came out, shown before we leave

What's not

  • Furnace or air handler internals (blower, evaporator coil). Ask and we will tell you whether it needs a separate visit.
  • Duct repair, sealing or replacement. We will show you the problem but we do not do the construction work.
  • Mold remediation. If we see suspected growth we stop and tell you, and you bring in a remediation company first.
  • Pre-1980 cement-board (transite) or paper-wrapped ducts that may contain asbestos. We do not agitate these. Get them tested first.

Process

How the visit goes

  1. 01

    Walkthrough and vent count

    We count supply and return openings with you, confirm the price on the spot, and look at the furnace and duct type.

  2. 02

    Protect and seal

    Drop cloths go down at every register. Every opening except the one we are working gets sealed so the vacuum pulls through the run we are cleaning.

  3. 03

    Negative-air connection

    The vacuum connects to the supply trunk, then the return trunk. Loosened dust travels to the collection drum, not into your house.

  4. 04

    Agitate every run

    From each register we run an air whip or rotary brush the full length of the branch back to the trunk. Long runs and elbows get extra passes.

  5. 05

    Registers washed, filter checked

    Every cover gets washed and dried. We check the furnace filter and tell you if it needs replacing.

  6. 06

    Show and tell

    You see the debris drum and photos of the duct interiors. Then we put every register back and clean up.

Warning signs

Signs it is time

Dust returns days after you clean

A grey film on furniture within a week of dusting usually means the supply ducts are shedding.

You just finished a remodel

Drywall dust and sawdust end up in open ducts on almost every renovation, then blow out for months.

Registers look dark inside

Pull one cover. If the louvers and the first foot of duct are furry, the rest of the run is too.

You bought the house and nobody knows the history

Ducts are the one system the inspection report skips. New owners are our most common call.

Rodent signs in the attic

Droppings near duct runs or chewed flex duct mean the ducts need cleaning and the damage needs a look.

A musty smell when the fan starts

That first-blast smell comes from what is sitting in the runs and plenum.

FAQ

Air Duct Cleaning: questions people ask

How much does air duct cleaning cost?
Air duct cleaning costs $349 for up to 10 vents and $19 for each vent past ten. Count every supply register and return grille in the house to get your number. A 2-bedroom condo with 7 vents is $349. A 4-bedroom house with 16 vents is $463. There are no fuel charges or per-system add-ons, and the price you get on the phone is the price on the invoice unless the vent count changes.
How long does air duct cleaning take?
Plan on 2 to 4 hours for a typical single-family home. A small condo can take 90 minutes. A large two-story home with two systems and 20-plus vents can take most of a day. We give you a time estimate when we confirm the vent count.
Do you clean the furnace too?
No. The $349 service covers the ductwork, trunk lines, plenums we can reach, and the register covers. The blower and evaporator coil inside the furnace are a separate job. We check your filter and tell you what we see.
What does a vent count as?
Every supply register and every return grille counts as one vent. A return is the large grille, often in a hallway ceiling or wall, where air gets pulled back to the furnace. Most homes have 1 or 2 returns and 8 to 14 supplies.
How often should air ducts be cleaned?
Every 3 to 5 years for most Bay Area homes, sooner after a remodel, a rodent problem or a heavy smoke season. There is no rule that fits every house. If you pull a register and the first foot of duct is clean, you can wait.
Will duct cleaning make a mess in my house?
No. The vacuum keeps the system under negative pressure, so loosened dust travels to our collection drum instead of out the registers. We put drop cloths at every opening and wipe down the register areas when we are done.
Can you clean flex duct?
Yes. Flex duct gets air whips instead of hard brushes so the inner liner is not torn. If a flex run is crushed, kinked or disconnected in the attic we will show you a photo and tell you what a repair would involve.
Do you use chemicals or sanitizers in the ducts?
No. We clean mechanically with vacuum and agitation. We do not spray sanitizers or deodorizers into ductwork.
What if my ducts are the old cement-board kind?
We stop. Cement-board and some paper-wrapped ducts in homes built before 1980 can contain asbestos, and agitating them is the one thing you should not do. Get a sample tested first. If it tests clean, we clean it.
Is duct cleaning worth it?
It is worth it when there is something in the ducts to remove: remodel dust, rodent debris, years of buildup, or a smoke season that coated everything. It is not worth it on a 3-year-old house with clean registers. Pull one register cover and look. We will tell you the same thing on the phone.
