Air Duct Cleaning in Burlingame, CA

Frequently Asked Questions

1. My 1920s house in the Easton Addition has ducts running through the crawlspace — is that why the air smells musty when the heat first comes on?

   Usually, yes. Nearly every pre-war home here sits on a raised foundation. The forced-air system was added decades after the house was built, so the supply runs live in a shaded, damp crawlspace rather than inside conditioned space. Cold metal and flex in that environment collect condensation, and the dust already inside the duct turns into something that smells when warm air pushes through it the first time each season. We check the crawlspace conditions along with the ducts, because cleaning the duct without noting standing moisture or a sagging run collecting water just resets the clock.

2. What usually turns out to be wrong with the ductwork in older Burlingame homes?

   The most common findings are long flex runs that have sagged into low spots, disconnected or partially pulled-off boots at the register, and rodent intrusion. Chewed flex and nesting material in the crawlspace shows up regularly on the older blocks. Many of these houses also still have legacy sheet metal trunks from an earlier retrofit, and some of those are wrapped in asbestos tape at the joints. If we see suspected asbestos-containing tape, we stop and tell you. We don't disturb it, and that work belongs to an abatement contractor, not a duct cleaner.

3. How far ahead do I need to book, and how fast can someone get out here?

   Burlingame is a short drive for our crews and most requests get scheduled within a few days. Crawlspace work takes longer to quote accurately over the phone than attic work does, so we ask a few questions up front about access: where the crawl hatch is, whether it's inside a closet or on an exterior wall, and roughly how tight the clearance is. If the furnace has already quit or you're smelling rodent, say so when you call and we'll prioritize it.

4. Can you do it the same day I call?

   Sometimes, depending on cancellations and where the crew is that afternoon. It's more realistic for an apartment or condo near the Broadway or Burlingame Avenue corridor, where the unit's runs are short and access is straightforward. A full Craftsman or Spanish Colonial with a complete crawlspace system is a longer job and generally gets its own slot rather than being squeezed in at the end of a day, since rushing it in a tight crawlspace is how boots get knocked loose.
