HVAC Duct Cleaning in San Mateo, CA

Why San Mateo ducts load up with dust

Most of the dirt comes in below the floor. Raised foundations here have crawlspaces that stay damp. Panned floor-joist and wall-stud returns in older homes were never sealed. They pull crawlspace and wall-void air straight into the blower. Add a filter slot with no gasket and unfiltered air bypasses entirely. The grime that lands is a mix: fine salt and marine aerosol, bay mudflat and construction silt, tree and grass pollen March through June, wildfire soot in late summer.

Rodents matter too. Near the creeks and the baylands they chew flex jacket under raised foundations. Sagged flex that has dropped off its hangers pools in the belly. Debris and moisture collect there. On uninsulated metal runs, condensation grows mold on duct exteriors and at boot connections.

Scope on a typical job: supply and return cleaning. Blower wheel and coil surfaces. Registers and boots. Sealing recommendations at boots and plenums. Sanitizing only where crawlspace moisture actually produced growth.

One caution. Original 1920s–40s gravity octopus trunks sometimes carry asbestos tape or jacket. That is abatement work, not cleaning, and we stop. Also know that weak airflow here usually traces to crushed branch runs. Sometimes a dirty blower wheel. Sometimes an undersized return. Cleaning alone will not fix those.

What Happens After You Call Us

Step 1

Call and tell us what you're seeing, dust on the registers, weak airflow in the back bedrooms, a dryer that needs two cycles. We book a two hour arrival window and text you when the van is twenty minutes out.

Step 2

We open the furnace closet, pull a register or two, and look at the crawlspace or attic runs first. The estimate is free, and you get one firm number for the supply and return count we actually find.

Step 3

We clean the lines, check airflow at each register, vacuum up anything we tracked in, and show you before and after photos. You pay the number we quoted, even if the crawlspace runs longer than expected.
