Even a good furnace or AC can't overcome ductwork losing air. Measurement replaces assumption on every visit.
San Mateo homeowners often assume duct problems when comfort is off but equipment seems fine, and they're often right — disconnected sections and torn insulation are common in attics and crawl spaces. We inspect the full run, not just the sections near the equipment, since damage tends to hide exactly where it's hardest to see.
What every duct assessment includes.
Leakage gets measured with a duct blaster test.
Not just visible sections.
Every joint gets mastic and a proper mechanical fastener, never the cloth tape that peels off in a season or two.
You see proof the fix landed, not just our word for it.
Evidence, not just our word for it.
Six issues that come up on most inspections.
Testing comes before sealing.
A crushed flex run or disconnected joint sends conditioned air straight into the attic.
We measure and correct pressure with damper adjustment or resizing where needed.
Damaged insulation leads to condensation and wasted energy.
Rodent damage to ducts is more common than people realize.
An undersized trunk or poorly routed branch can bottleneck airflow.
What to expect.
Tell us what's off.
A tech shows up with testing equipment ready to go.
We measure first and explain findings, then quote a flat-rate repair.
Re-testing before we call it done.

— T. Osayande, home baker

— R. Kowalczyk-Ibe, homeowner

— N. Falowo, gallery owner
Common questions before a Ductwork Repair assessment.

That gray cloth tape everyone associates with ducts becomes brittle and peels within a season or two.
Significant leakage in attic or crawl space runs can waste a meaningful share.
Rodent damage affects performance, not just appearance.
The fix gets done the same day we find the problem, in most cases.
Longer for extensive resizing.
Documentation is standard, not a special request.
We will flag anything unusual before starting.
