Our process
How a air duct repair visit actually goes.
Every step is specific to this service — no generic checklist, no surprises once we arrive.
- 01
Pressure-test the duct system
We measure leakage and walk the duct runs in attic, basement, or crawlspace to pinpoint where conditioned air is escaping.
- 02
Mark every leak, tear & failed joint
Disconnected boots, crushed flex, torn insulation, and unsealed seams are documented with photos before any work begins.
- 03
Seal joints with mastic & UL-listed tape
Every accessible seam is sealed properly — no cloth duct tape, no shortcuts that fail in a season.
- 04
Replace damaged sections
Crushed flex, torn liners, and rusted boots are cut out and rebuilt with new materials matched to the existing system.
- 05
Re-balance airflow to each room
Dampers are adjusted so rooms that were starved for air finally get their share without robbing the rest of the house.
- 06
Re-test and document the result
We re-run the leakage check, hand you before/after numbers, and explain what changed and why.

Why air duct repair matters
The U.S. Department of Energy estimates that the average home loses 20–30% of the air moving through its ductwork to leaks, holes, and poorly connected joints. In New Jersey homes — especially older ones with ducts running through unconditioned attics, basements, and crawlspaces — that loss is often even higher.
When your system is leaking, you're paying to heat or cool spaces you never use. Worse, leaks pull in dust, mold spores, and even sewer gases from those same unconditioned areas and push them into your living rooms and bedrooms.
What we repair
We service both flexible and rigid metal ductwork in residential and light-commercial systems. Common repairs include sealing joints with mastic or UL-listed foil tape, replacing crushed or disconnected flex runs, repairing torn insulation, replacing damaged boots and registers, and rebuilding poorly designed transitions that strangle airflow.
After repair we test the system, balance airflow across vents, and walk you through what we found so you understand exactly what changed.

Questions homeowners ask.
Can you repair flexible and rigid ducts?
Yes — we service both flexible and rigid metal ductwork in residential and light-commercial systems.
Will I need to replace my whole system?
Almost never. Most issues are localized to a section or joint and can be repaired without replacing the whole run.
How quickly can you come out?
Typically within a few days. For urgent issues in NJ, we can often schedule same-week.
Will repairs really lower my bills?
Yes — sealing leaky ductwork is one of the highest-ROI HVAC improvements you can make, often paying for itself within a year or two.
Do you offer duct sealing as a separate service?
Yes. If your ducts are structurally fine but leaky, sealing alone can dramatically improve efficiency.
