Air Duct Cleaning in San Rafael: Common Questions

How often do ducts in a San Rafael house actually need cleaning?

Most homes here do fine on a five to eight year cycle. What shortens it is the local pattern: heat runs October through May, the cooling season is short but real, and the system sits idle for months before it pushes settled crawlspace and attic dust through the house on the first cold morning or the first 90-degree October afternoon. If you've had a remodel, a crawlspace that floods in the wet winter months, or a new pet, move it up.

What happens during the visit, and how long are you in my house?

We seal off the supply and return registers, hook a negative-air machine to the trunk line, then work each run with rotating brushes and compressed air so debris travels toward the vacuum instead of into your rooms. A typical San Rafael single-story ranch in Terra Linda takes two to four hours; a Victorian or Craftsman in Gerstle Park or Dominican with retrofitted forced air over an old gravity furnace layout can run longer because the trunks are buried in a crawlspace or basement and access is tight. We check the blower and coil while we're in there and tell you what we see.

Why does one house cost more than the next?

Count of supply runs is the biggest driver, followed by how hard the ductwork is to reach. Flat-roof Eichler-influenced plans with under-slab or crawl runs and pan returns take more setup than an open attic. Older downtown homes with sheet metal trunks and asbestos-tape joints at the seams need careful handling and sometimes a different approach at those seams, which adds time. We look at the system in person, give you a free estimate, and you approve a fixed number before we open anything.

Does the dryer vent get cleaned along with the ducts, or is that booked on its own?

It's a separate line item, not folded into the duct work. Plenty of customers add it while we're already on site since the equipment is in the truck and it only takes a short while. Worth doing if your dryer takes two cycles to finish a load or the laundry room feels humid.

What do you do if there's mold growing in the system?

We stop and show you. Growth usually turns up on flex runs in unconditioned space or near a coil with a drainage problem, and in Marin that often traces back to wet-winter humidity in a shallow crawlspace. Cleaning alone won't fix it if moisture keeps feeding it, so we treat what we can reach, flag the source, and tell you straight if the duct needs replacing instead. If testing is warranted we'll say so rather than guess.

Is there a surcharge for booking a same-day appointment?

No. Same-day work is billed exactly like an appointment set a week out. We keep slots open across San Rafael and the northern valleys because people usually call when the heat kicks on in October and the house smells like dust. Call early and we'll tell you honestly whether today is realistic.

What happens after you call us

  1. 1

    Call and tell us how many supply registers you have and where the furnace sits, crawlspace, attic or closet. We book a two hour arrival window and text you the tech's name before he leaves the shop.

  2. 2

    He walks the house first, pulls a register cover, checks the return and the trunk line, then gives you one firm number. Vent count, flex versus sheet metal, and crawlspace access move that price.

  3. 3

    We tape off the registers, run the vacuum under negative pressure, test airflow at every supply, and put the covers back clean. You pay the number you were quoted, nothing added after the fact.

Call (415) 223-3423 and tell us what you're seeing at the registers, we'll quote it before any work starts, book only if you want to.

What San Rafael Homeowners Hire Us For

  • We work the pre-1940 Gerstle Park and Dominican houses, and we stop and call you if we find asbestos tape on the joints instead of cutting into it.

  • The truck carries flex duct, mastic, foil tape, boot collars and the common 16x25 and 20x25 filters, so a torn run in a Terra Linda attic gets replaced the same visit.

  • We pull every register and return grille, wash them off the wall, and photograph the inside of your trunk line before and after so you see what came out.

  • Booking runs about two to four days out in October, and we tell you that honestly on the phone rather than promising a window we'll miss.

What duct cleaning actually involves in San Rafael homes

The thing worth worrying about is not dust. It is what a brush can disturb. Pre-1940 houses downtown and around Gerstle Park and Dominican still carry sheet metal trunks in the crawlspace, and the seams are often taped with asbestos-containing joint wrap. A spinning brush pushed through that is a hazard, not a cleaning. We inspect seams before anything turns. If the tape looks suspect, work stops and abatement comes first.

Marin County seat, inland side of the hills, wet November through March. Crawlspaces here hold that water for months. Gravity and floor furnaces were retrofitted to forced air in a lot of these homes, and the old returns often pull air straight from framing cavities. That is how damp crawlspace odor ends up in a bedroom.

Terra Linda and the northern valley tracts are a different job. Low attic runs over flat and shallow-pitch roofs, slab or shallow crawl, sometimes under-slab runs we will not pretend to reach with a brush. Additions from the 1980s on are insulated flex, which tears if handled like metal.

Systems sit idle May through October here. Then comes a 90-degree October afternoon or the first cold morning, and months of settled dust moves at once. That is the call we usually get.
