Question 1

How often do air ducts actually need cleaning?

Accepted Answer

For most San Mateo homes, every three to five years is honest. Push it sooner if you've had a remodel, if you're running a furnace that's been sitting unused since spring, or if the ductwork runs through a crawl space that stays damp through our cool wet winters. Homes on the flats with supply trunks and flex branches under the floor tend to need it more often than hillside split-levels west toward Hillsdale with attic runs.

Question 2

What does a duct cleaning appointment actually look like start to finish?

Accepted Answer

We seal off the system, put a negative-air machine on the trunk line, and work each supply and return with rotating brushes and compressed air so debris pulls toward the vacuum instead of into your rooms. Registers come off and get cleaned separately, and we check the blower compartment while we're in there. Most single-family homes take two to four hours. Older prewar bungalows near downtown with retrofitted forced-air can run longer because the runs are awkward and the access points are few.

Question 3

What makes one quote higher than another?

Accepted Answer

The number of supply and return runs is the biggest factor, followed by how hard they are to reach. A postwar tract ranch on the flats with a crawlspace foundation means we're working on our backs under the floor, which takes longer than a clean attic layout. Sagging or torn flex branches, a furnace that's never been serviced, and systems with two air handlers all move it up. We look at the system in person first and tell you the number before we touch anything.

Question 4

Is the dryer vent part of duct cleaning or billed on its own?

Accepted Answer

Separate service, separate line item. It's a different machine and a different access point, so it isn't bundled in. Plenty of San Mateo customers add it the same visit since we're already on site, and that's the cheapest way to do it. Long vent runs in 1940s-50s tract homes clog with lint faster than people expect.

Question 5

I think I see mold in a vent. What then?

Accepted Answer

We stop and show you. Marine layer and fog pushing through the San Bruno/Crystal Springs gaps most summer mornings keeps crawl spaces humid here, so growth on duct interiors and around registers is something we see in mid-Peninsula San Mateo County. Light surface growth we can treat with an antimicrobial as part of the cleaning. Anything widespread, or anything tied to standing water under the house, needs a remediation contractor, and we'll say so rather than clean over it.

Question 6

Is there a surcharge for a same-day visit?

Accepted Answer

No. Same-day is the same rate as a slot booked next week. If a truck is open in San Mateo we'll take the call. We service Carrier, Trane, Lennox, Goodman, Rheem, and American Standard systems, so most setups we show up already knowing the layout.
