Air Duct Cleaning in Sunnyvale, CA

What Sunnyvale homes actually do to duct systems
Most of this city was orchard before it was housing. The tract ranches that replaced those trees went up on slab, single story, from the 1950s through the 1970s. Ponderosa Park, Birdland, Cherry Chase, same basic plan repeated. Some have short sheet-metal trunks in a low attic. Others have perimeter duct cast into the slab itself. Which one you own changes everything about the work.
In-slab runs cannot be brushed like sheet metal. They hold silt. Low spots collect water after a pipe leak or heavy rain. We camera them before touching anything. If a run is crushed, cracked, or holding standing water, cleaning is the wrong answer and we say so. That system needs rerouting overhead, not a vacuum.
The attic systems have a different problem. One central hallway return, undersized for the AC somebody added decades later. High velocity at that grille pulls air through gaps in the wall cavity. Attic dust rides along. You see the gray outline on the ceiling paint.
Then there are the additions. Second stories and kitchen gut jobs are constant here. Fine gypsum dust settles in branch runs and register boots, and spring pollen off the remaining apricot trees and street trees loads it further.
What Happens After You Call Us
Call and tell us how many supply vents and returns you have, and we give you a two-hour arrival window plus a text when the tech leaves for your address.
We walk the system first, check whether your runs are attic sheet metal or under-slab, count the vents, and hand you a firm written quote before a single register comes off.
We clean every run, seal the access cuts, vacuum up after ourselves, run the system so you can feel the airflow, and you pay the quoted number, nothing added.

Our ranch house still has its original ductwork — is it worth cleaning, or should we just replace it?
In most of Sunnyvale's 1950s-70s single-story homes, cleaning is the reasonable first step. The short sheet-metal trunks running through the attic are usually sound metal and clean up well; what they hold is decades of settled dust, insulation fiber, and drywall dust from remodels. Where cleaning isn't the answer is in-slab perimeter duct that has taken on moisture or has collapsed liner, or old flex branches that are crushed, torn, or disconnected above the ceiling. Those we document with photos and hand back to you as a repair decision, not something we can wave away. We also open small access panels in the trunk to clean properly and seal them when we're done, so you're not left with holes in the metal.
What do you usually find wrong in Sunnyvale duct systems?
A few things come up constantly. One is the single central hallway return: one grille doing all the work for the whole house, so everything the house makes gets pulled through one path and that filter and return boot loads up fast. Another is undersized duct left in place after an AC upgrade, which moves less air than the new equipment expects and tends to leave the far bedrooms dusty and weak. Then there's construction debris. There's a lot of remodeling and second-story addition work here, and drywall dust and sawdust get into branch runs and stay there long after the contractor leaves. On the orchard-era lots, spring tree and grass pollen pulled in through a leaky return is the other common complaint.
