Duct Replacement & Repair — Installation • Sealing • Balancing

Fix uneven rooms, noise, and high bills at the source. Proper ducts let your heater (and AC) breathe: right size, tight seals, and balanced airflow. We repair trouble spots or replace runs end-to-end—then test and tune so every room gets its share.

Signs you need duct work

  • Some rooms hot, others stay cool
  • Whistling, rattling, or “oil-can” popping
  • Dusty home, musty attic/crawl odors, weak airflow
  • High utility bills, short cycling, burnt or restrictive filters

What we repair/replace

  • Leaky joints & boots (UL-181 mastic/tape, sealed and strapped)
  • Crushed/oversized flex and kinked takeoffs
  • Undersized returns and noisy grilles (we add/resize returns)
  • Metal trunks & plenums with clean transitions
  • Insulation upgrades (typically R-8 in unconditioned spaces)
  • Vibration isolation and sound lining where it helps

How we size & balance (simple)

We measure system static pressure and target proper airflow (~400 CFM per ton as a typical design point), then set each run for the room’s load. Result: quieter operation, steadier temps, and equipment that isn’t “strangling” for air.

Installation process

  1. On-site assessment: duct sizing/layout, leakage, returns, attic/crawl access.
  2. Options & written pricing after the visit: repair vs. partial/whole replacement.
  3. Permits & scheduling where required.
  4. Professional install: metal trunks + right-length flex, sealed connections, insulated runs, tidy supports.
  5. Test & balance: verify static, room airflow, and temperature—then walk you through filter sizing and simple care.

Our services are just as easy to schedule across multiple parts of the Bay Area. In the South Bay, we serve San Jose, Sunnyvale, Los Gatos, Saratoga, Campbell, Cambrian Park, Cupertino, Mountain View, Los Altos, Palo Alto, and Menlo Park.

In the East Bay, we’re available in Fremont, Newark, Milpitas, and Union City—so wherever you are in our service area, help is close by and simple to book.
