Air Duct Cleaning in Millbrae, CA

That's the first thing we look at in Millbrae, because the answer is genuinely split. A lot of the forced-air retrofits under these postwar stucco homes are sheet metal run through a damp crawlspace, and after decades in marine air the galvanized trunk and the boots at the floor registers show surface corrosion. If the metal is sound and the seams and boot connections are intact, cleaning plus resealing gets you a system worth keeping. If we put a camera in and find rusted-through boots, flex that has collapsed or torn, or duct sitting in standing moisture, cleaning won't fix it and we'll tell you so rather than take the job. We'd rather you spend the money once on replacement of the bad runs.

Access and run layout, mostly. These homes tend to have short trunk runs and a small number of registers, which works in your favor. There's less linear footage than a sprawling single-story elsewhere on the Peninsula. What adds time is crawlspace work: low clearance under the older tract homes, tight hatches, and ducts that have to be cleaned from below rather than from a comfortable attic. Homes with only one or two returns also take extra care, since everything has to be pulled through a limited number of pickup points. Condos and apartment units near the BART and Caltrain station are usually quicker and priced accordingly. We walk the crawlspace and count registers before quoting anything, so the number reflects your actual system.
