Frequently Asked Questions - Air Duct Cleaning in San Mateo, CA
These are the questions San Mateo homeowners ask us most often, answered directly so you can decide without a sales pitch. If your question isn't here, call (866) 894-2153. We answer 24/7.
Pricing & Cost FAQs
Air duct cleaning in San Mateo typically runs about $400 to $700 for a standard whole-home system, with larger homes, multiple systems, or heavy buildup at the upper end. Those are honest whole-system estimates, not per-vent pricing, and the written estimate you get before any work starts sets the final number. What drives the range is the number of systems, how accessible the ductwork is, and how much debris has built up over years of Peninsula living. Call (866) 894-2153 for an exact quote. Estimates are free.
Low headline prices usually reflect a per-vent model that grows once the technician is on site, or a quick surface pass that never reaches the trunk lines. We don't play that game. One flat price per system gets agreed in writing before work begins, and there are no surprise add-ons midway through the job. If a quote looks too good to be true, ask what's actually included: the trunk lines, the registers, the blower housing, and before-and-after photos of your own ducts. Call (866) 894-2153 and we'll walk you through what fair pricing looks like.
We price per system, not per vent. Per-vent pricing punishes homes with more registers and rewards quick work that skips the main trunk lines, which are usually where the real buildup sits. A whole-system price covers the supply and return runs, the registers, and the components inside the air handler, so the estimate you agree to is the total. For San Mateo homes with an older ranch layout or a split-level, we'll confirm the system count during the estimate. Call (866) 894-2153 to get started.
The estimate is free, and there's no service-call fee attached to it. We look at your system, count the runs, and give you a written range before any cleaning happens. If the scope is bigger than expected, that's discussed before work begins, not discovered on the invoice. You'll know the number before anyone touches a duct. Call (866) 894-2153. Estimates are free and the price is set per job by the written estimate.
Homes in hillside areas like Hillsborough or low-lying Foster City typically land on the higher end of the range, often $600 to $900, because they tend to have more square footage, sometimes two systems, and longer duct runs. Foster City's newer infill construction uses tight, sealed ductwork that can hold fine dust differently than older San Mateo homes. Both still get the same flat-per-system pricing and the same written estimate before work begins. Call (866) 894-2153 for an exact quote on your home.
Service & Process FAQs
A typical job starts with airflow testing and a camera inspection, then negative-pressure containment to keep dust out of your living space. Technicians run rotating brush and air-whip tools through the supply and return runs, clean the registers and grates, and address the blower housing and evaporator coil area where dirt accumulates. We use truck-style equipment from Abatement Technologies and Rotobrush depending on the job. Before-and-after photos of your own ducts are part of the wrap-up, so you see what changed. Call (866) 894-2153 with any process questions.
Yes, and the before-and-after photos are how. A surface wipe hits the visible registers and leaves the trunk lines and plenum untouched. A real cleaning uses negative pressure, reaches into the main runs, and documents the difference with pictures from inside the ductwork. If a company can't show you photos of your own system, you don't really know what happened. We document every job. Call (866) 894-2153 to schedule.
Most single-system San Mateo homes take about three to five hours. Two-system homes or homes with heavy buildup take longer, sometimes a full day. The timeline depends on accessibility, how much ductwork there is, and whether the air handler needs extra attention. We give you a realistic window with the written estimate so you can plan your day. Call (866) 894-2153. Fast dispatch, 7am-7pm.
Most homes should have ducts cleaned every three to five years, and sooner if you've had renovation dust, a pest issue, or visible debris at the registers. Homes near the 101 or 92 corridors tend to pull in more road dust, and older San Mateo housing stock with pre-1990 ductwork often needs it on the shorter end of that cycle. If it's been more than five years, an inspection is worth it. Call (866) 894-2153.
Not effectively, and not safely. Consumer vacuums and shop vacs don't generate the negative pressure needed to dislodge debris from trunk lines, and reaching into ductwork blindly risks damaging the liner or the blower. The components inside the air handler sit near live electrical connections, which is a job for a trained technician. Professional cleaning also gives you documentation you can use with a landlord, insurer or buyer. Call (866) 894-2153 to book an inspection.
Yes, the blower housing and the evaporator coil area are part of a proper whole-system cleaning. Those are the components that recirculate air, so skipping them leaves a dust source feeding right back into clean ducts. Coil cleaning and blower cleaning are handled by trained technicians using the appropriate tools. We'll confirm what's covered at your free estimate. Call (866) 894-2153.
Brands & Equipment FAQs
The equipment varies by job, but our technicians work with established industry lines including Abatement Technologies negative-air units and Rotobrush brush-and-vacuum systems. Those are the tools that let a crew reach into main trunk runs and capture debris at the source. Nikro and Guardsman equipment also appears on some jobs depending on duct type and access. The right tool matters less than whether the crew uses it thoroughly. Call (866) 894-2153 to ask what your setup would need.
Sometimes, yes. Guardsman and Nikro equipment are used on certain residential jobs depending on duct type, access, and how much containment is required. The choice depends on your ductwork, not on a fixed shopping list. When we give you the free estimate, we can explain which setup fits your home. Call (866) 894-2153.
