Air Duct Cleaning in Newark, CA

Frequently Asked Questions

My attic ducts are rusting at the boots from the salt air. Is cleaning worth it, or should I just replace them?

It depends on what the rust has actually done. In Newark's older single-story tracts, the flex runs are usually fine while the sheet metal pieces take the damage first: the boots where the duct meets the ceiling register, and the plenum seams above the garage furnace. If those are surface-rusted but still solid and sealed, cleaning is worthwhile and you'll get years more out of the system. If a boot has rusted through or the plenum seam has opened up, cleaning it won't fix anything, because the duct is now pulling attic air. We look before we quote and tell you honestly which of the two you're looking at. Often it's a mix: clean the system, replace two or three bad boots.

We keep smelling the marsh inside the house. Will duct cleaning stop that?

Sometimes, and sometimes only partly. Living this close to the refuge marshes, that low-tide smell is in the outside air, and the usual path indoors is a leaky return. If the return cavity or the duct back to the furnace has gaps, the blower pulls unconditioned air in from the attic or the garage wall and delivers it to every room. Cleaning removes the settled silt and biofilm that holds the odor, but if the leak stays open the smell comes back with the next tide and wind shift. We check return connections as part of the job and point out where the air is actually getting in, so you're not paying to clean the same problem twice.

What makes one Newark house cost more than another for the same service?

The main drivers here are the number of supply registers and how the ductwork is laid out. The 1950s–70s slab tracts are generally straightforward: one furnace in the garage, everything running through the attic, a predictable register count. Two-story townhomes and condos take longer because there are often two zones or a longer trunk line, and some of the newer builds near the old Dumbarton area have tighter attic access. Condition matters too. Ducts packed with fine bay silt take more time than ones kept up with regular filter changes. We give you the number after seeing the system, not from a phone guess.

How soon can someone come out, and do you do same-day?

Newark is compact and we cover the whole city plus the surrounding Fremont and Union City area, so getting a tech here isn't a long haul. Same-day is often possible, especially mid-week and outside the stretch when the first real summer heat arrives and everyone fires up the AC at once. That week we book out further. If you're dealing with an odor complaint or dust coming from the vents, say so when you call and we'll try to fit you in sooner rather than scheduling you out.

Why do my filters get dirty so fast here?

Fine silt blows off the mudflats and it's light, so it travels and gets past cheap filters. Combine that with cool humid marine air and you get a film in the ducts that grabs more dust than dry dust alone would. If you're swapping filters far more often than the box says, that's normal for this part of the bay plain and not a sign your system is broken. What it does mean is that whatever got past the filter over the years is sitting in the duct runs and at the blower. Cleaning the system and matching your filter to what the blower can actually handle makes a bigger difference here than it would a few miles inland.
