Air Duct Cleaning in Fairfax, CA

Frequently Asked Questions

My house is a 1930s cottage with a crawlspace you can barely get into. Can you even clean ducts under there?

Usually yes, but it depends on clearance. A lot of Fairfax cottages and cabins sit on steep lots with partial crawlspaces, and the forced-air system was retrofitted long after the house was built, so the trunk and branches were squeezed into whatever room was left. We check access first. If a tech can reach the plenum and the boots, we can clean it. If sections are buried behind foundation cribbing or pinched under a low joist bay, we'll tell you what we can reach and what we can't, rather than pretending the whole run got done.

We ran the wood stove hard all winter and there's a smoky film on things. Will duct cleaning help?

It helps with what's in the ducts, which is real but partial. Wood smoke and fireplace soot are fine particles that settle in supply boots, on register louvers and in the blower compartment, then get stirred up every time the furnace cycles. Cleaning removes that reservoir. What it won't do is address soot already embedded in drapes, upholstery and painted surfaces, or stop a stove that's spilling because of draft problems. If the smell is sharpest right when the heat kicks on, the ducts are a big part of it.

After a fire-season smoke event, how fast can someone get out here?

Scheduling in Fairfax is normally within a few days. The exception is the stretch after a regional smoke episode, when every house on the wildland edge in Ross Valley calls the same week and the queue stretches. Same-day does happen when there's a cancellation or when we're already working nearby in the valley, but we won't promise it on the phone. If ash got pulled into the system, sealing the house and changing the filter buys you time until we can get there.

What usually turns out to be wrong with the ductwork in homes around here?

Short, kinked flex is the most common thing we find. When a forced-air system gets fitted into an underfloor space that was never meant for it, runs get bent tight around pipe and framing, and debris collects in the low spots. We also see flex that has sagged off its hangers or pulled loose at a boot, which means the system is drawing crawlspace air. In a damp, wooded canyon that air carries moisture and whatever is growing down there. Older homes still running wall or floor furnaces have no duct system at all, just a grille, and those need a different conversation.

What makes the price go up or down on a Fairfax house?

Mostly access and layout rather than square footage. A small cottage can take longer than a larger flat-lot house if the crawlspace clearance forces slow work, or if the retrofit put the air handler somewhere awkward. Number of supply registers matters, and so does condition. Heavy soot loading from winter stove use, or ash pulled in during a smoke event, takes more passes than routine dust. Few homes here have AC, so there's typically no evaporator coil adding to the job. We walk the system and tell you what it'll involve before anyone unpacks equipment.
