Stop Wasting Energy with Leaky, Inefficient Ductwork

Expert Ductwork Services

You can buy the most efficient HVAC system on the market, but if your ductwork is damaged or poorly designed, you'll lose performance and money. We seal, repair, and redesign ducts.

Why Ductwork Fails

Deterioration Over Time: Old, brittle flexible ducting tears easily and loses its insulation value.
Poor Initial Design: Improperly sized ducts severely restrict airflow, causing hot and cold spots.
Pest Intrusions: Rodents commonly chew through ductwork seeking warmth, creating massive air leaks.
Unsealed Connections: Metal joints that were never sealed with mastic slowly pull in dusty attic air.

The Impact of Properly Sealed Ductwork

Eliminates frustrating hot and cold spots in distant bedrooms
Stops wasting your conditioned air in the dirty attic or crawlspace
Prevents attic dust and fiberglass from being sucked into your living areas
Can lower your heating and cooling costs by up to 30% immediately

Airflow Restoration & Duct Replacement

We take a scientific approach to airflow. We can test the static pressure of your system to identify blockages. Whether you need a few leaky joints sealed with professional-grade mastic, a crushed section of flex-duct replaced, or a complete whole-house ductwork redesign, we have the expertise to execute it perfectly.

Our Ductwork Solutions

We ensure the air you pay to heat or cool actually reaches your living space:

1. Thorough Attic/Crawlspace Inspection: We visually inspect every foot of accessible ductwork for damage and leaks.
2. Manual Sealing: We seal seams, joints, and plenums using heavy-duty mastic and foil tape.
3. Damper Balancing: We adjust internal dampers to push more air to rooms that struggle to cool or heat.
4. Complete Redesign: For severely degraded systems, we install all-new, high R-value insulated ducting.

Premium Brands We Service

FAQs About Ductwork Services

Common questions from San Bruno homeowners.

Signs of leaky ducts include unusually high energy bills, rooms that never get warm or cool enough, excessive dust in the house, and whistling noises coming from the vents.

If your ductwork is less than 15 years old and mostly intact, professional mastic sealing is usually sufficient. If it is old, crushed, or degraded fiberglass flex-duct, full replacement is more cost-effective long term.

Ductwork replacement costs vary widely based on attic or crawlspace accessibility and the size of the home. We provide free on-site inspections to give you a precise, written estimate.

Aeroseal is a technology that blows a non-toxic aerosol polymer into your ductwork to seal leaks from the inside out. While we do manual mastic sealing, we can advise if your home is a good candidate for advanced sealing.

In most cases, no. We can access and repair 90% of your ductwork directly from your attic, basement, or crawlspace without damaging any drywall inside your home.
