Sealing the Leaks Your System Never Told You About

Losing Air Before It Reaches the Vent? Ductwork Repair in San Francisco, CA

Name: AAA Pro HVAC
Telephone: +1-866-805-8548
Price range: $$
Rating: 4.9

A surprising share of a home's conditioned air never reaches the vents at all — it escapes through leaky duct joints in the attic or crawlspace.

Insulation and airflow balancing are addressed together, not treated as separate problems.

If you're dealing with one room that never quite reaches temperature, unusually high utility bills relative to system size, or visible disconnected duct runs discovered in the attic, you already know leaky or poorly balanced ductwork can waste a significant share of a system's output before it ever reaches a single vent, and most homeowners never know to check.

Duct Leakage Testing, Not Guesswork

Findings are documented with real numbers, before-and-after.

Disconnected Duct Run Repair

Airflow Balancing & Damper Adjustment

Room-by-room airflow measurement identifies which zones are starved and which are over-supplied. Techs handling airflow balancing & damper adjustment carry the specific parts and tools this job calls for, not a generic kit.

Duct Insulation Repair & Replacement

Ductwork Repair FAQ

How do I know if my ductwork actually has leaks?+

Signs include uneven room temperatures, unusually high utility bills, and visible gaps at duct joints in an attic or crawlspace.

Is duct tape an acceptable long-term fix for duct leaks?+

Mastic sealant is the industry standard for a repair meant to last.

Can leaky ductwork really affect my utility bills that much?+

Yes — conditioned air lost through duct leaks before reaching the vents is effectively paid-for air that never does its job.

What's the difference between a duct leak and an airflow balancing problem?+

A leak physically loses air before it reaches the vent; a balancing problem means air reaches the vents but unevenly across rooms.

Do you inspect ductwork in attics and crawlspaces, or just what's visible?+

That's typically where the most significant leaks and disconnections are found.
