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.
