Question 1

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

Accepted Answer

Most homes here land in the three-to-five year range, and plenty go longer without any real problem. San Jose sits at the southern end of San Francisco Bay at the head of the Santa Clara Valley, where roughly 15 inches of rain falls Nov–Apr and summer rain is close to zero. That long dry stretch keeps dust airborne for months with nothing to wash it down, and wildfire smoke from Northern California fires in summer and fall pushes fine particulate into the system. If you've had smoke intrusion, a remodel, or new pets since the last cleaning, move it up.

Question 2

What happens during the appointment, and how long will my house be tied up?

Accepted Answer

We hook a negative-air machine to the trunk line, then work each supply and return with rotary 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 and coil area on Carrier, Trane, Lennox, Goodman, Rheem, and American Standard equipment. A single-story ranch with one system usually runs two to four hours. Two-story infill with two systems or a long attic run takes longer.

Question 3

Why does one house cost more to clean than the next one over?

Accepted Answer

Vent count is the biggest driver, then how hard the ducts are to reach. San Jose's postwar tract homes are built on slab, which pushed nearly every duct run up into an unconditioned attic, so access means crawling over joists in heat that hits 85–95F inside the attic on a summer afternoon. Flex duct that's crushed, disconnected, or packed with insulation adds time. Two systems cost more than one, and a condo tower unit off North First with a short compact run costs less than a sprawling ranch. We look at the actual system, not a phone guess, and the estimate is free.

Question 4

Do you handle the dryer vent at the same time, or is that a separate job?

Accepted Answer

It's a separate line item, not folded into the duct price. Most people add it while we're already on site because there's no second trip charge. Older tract homes often run the dryer vent through the attic or a long wall cavity to the roof, and those collect lint fast. If your dryer takes two cycles to finish a load, that's the vent.

Question 5

What if you find mold in there?

Accepted Answer

We stop and show you. Growth in a duct almost always means moisture is getting in somewhere, usually a sweating coil, a bad condensate drain, or hot humid attic air hitting cold metal. Cleaning without fixing the water source buys you a few months, nothing more. For anything beyond a small surface spot we'll tell you straight that it needs a remediation contractor, and we won't fog a chemical over it and call it handled.

Question 6

Is there an upcharge for same-day service?

Accepted Answer

No. Same-day costs the same as a scheduled visit. Winter inversions in the valley trap particulate and people notice it fast, so we hold open slots most days. Call in the morning and we'll tell you honestly whether we can reach you before evening.
