Duct repair and replacement in Bloomfield, NJ, one run at a time
When one room stays cold or hot while the rest of the house is fine, the duct that feeds it is often crushed, loose or leaking. We trace that run, find the failure and fix the section that needs it.
The room that never feels right
If the thermostat and the system seem normal but one register barely moves air, the problem is usually between the trunk and that register. A duct that came apart at a joint, flex duct crushed in the attic or a seam that has opened can send that air into the attic or the basement instead of the room.
Finding the failing section
Ducts usually fail in one place at a time, so replacing a whole system on a guess wastes money. We follow the run from the trunk to the weak register, checking each joint, bend and connection along the way, and photograph what we find. Most of the time the cause is clear once the run is traced.
- The run traced from the trunk to the weak register
- Every joint and transition checked along the way
- Crushed, kinked or separated sections photographed
A register that barely blows is usually a duct problem before it is a furnace problem.
What goes wrong in a duct run
Flex duct gets crushed when it is squeezed between framing or stepped on during other work in the attic. Joints pull apart when the duct was hung without enough support. Tape dries out and peels, and old mastic cracks, so seams open slowly over years. In older metal runs, rust can eat through the bottom of a duct where condensation collects.
When a section needs replacing
If a section is too damaged to repair, we replace it with new duct of the same size, so the system stays balanced. Every new joint is sealed and fastened, and insulation is put back where it was torn or missing.
- New flex or rigid duct sized to the run
- Joints sealed and fastened mechanically
- Insulation replaced where it was torn or missing
Why the seams matter
Many duct systems lose a lot of their air through small gaps at seams and joints rather than through one big hole. Those leaks are easy to miss because they are spread out. Sealing the joints we can reach while we repair a run helps the rooms at the end of the line get the air they should.
Reviews from our Google listing
A selection of our 5-star reviews on Google.
A hundred years of lime mortar requires a careful, low-RPM touch, and that antique sensibility was obvious in the preservation-grade sweeping of our 1910 hearth.
Soot was cleaned from the flue lining with non-abrasive polymer heads, leaving the critical structural integrity of the ceramic glaze undamaged.
Before any damage to the fundamental integrity of the ceiling, we were able to fix the outside chimney leaks after identifying significant water damage behind the lead counter-flashing.
Questions about duct repair
How do I know it is the duct and not the furnace?
If the system runs normally and only one or two rooms are weak, the duct to those rooms is the likely cause. If the whole house is uncomfortable, the equipment is more likely, and that is a job for your heating contractor.
Do you replace the whole system or one section?
Almost always one section. We trace the run, find where it failed and fix that part.
Is repair different from cleaning?
Yes. Cleaning removes debris from ducts that are intact. Repair fixes ducts that are crushed, loose or leaking.
