Air Duct Cleaning in Pasadena, CA

Often, partly. During wind events and after fires up in the Angeles National Forest, fine canyon grit and ash work in through gaps in the building envelope and get pulled into the return. In older Pasadena homes with a single undersized return, that return is working hard enough to draw air from the attic, crawlspace, or wall cavities around a poorly sealed filter grille, so whatever is in those spaces ends up in the trunk line. Cleaning the supply and return sides helps, but we'll also point out where the return boot or filter frame is leaking, because otherwise the dust comes right back.

Yes. Retrofits squeezed into a low attic over a period home usually mean tight working clearance, flex runs snaked between rafters, and an air handler set where you can barely stand. We work from the registers and from access points at the plenum rather than cutting new openings in plaster ceilings or original woodwork. If the attic run is older flex with a crushed or sagging section, we'll tell you (that's a repair question, not a cleaning one). Homes with basements or deep crawlspaces sometimes have the original gravity-furnace sheet metal still in place down there, which cleans differently than flex and takes longer.

The most common thing we find is original sheet metal spliced to newer flex with tape that's given up, so conditioned air is dumping into a crawlspace or attic and dusty air is being pulled in at the joint. Second is the single undersized return: one grille trying to feed a system sized for the whole house, which keeps the filter loaded and starves airflow. We also see spring pollen loading. Oak, sycamore and olive come through heavy enough that a filter installed in March looks months old by May. None of that is fixed by cleaning alone, but you should know about it before you decide what to spend money on.

Most Pasadena appointments land within a few days. Same-day happens when there's an opening, and it's more likely early in the week than on a Friday. The stretch where we book out furthest is late summer, when upper-90s inland heat has compressors running long hours and people notice weak airflow all at once, and the days right after a wind or fire event when half the foothills call about ash. If you're flexible on the time window, your odds of getting in quickly go up.
