Air Duct Repair & Vent Repair
in the Capital Region, NY

It follows the amount of damage: a few leaking joints is a smaller job, a long run that has pulled apart or a section that must be replaced is larger. We inspect first and quote one flat price you approve before work starts, never by the hour, and estimates are free. Replacing a failed AC is a separate job; see central AC installation.

Uneven temperatures from room to room, weak airflow at the registers, dust that keeps coming back, noise from the ducts when the system starts and higher energy bills are the common signs. Ducts in unconditioned attics, basements or crawl spaces are where leaks and pulled-apart joints turn up. If you see any of these, we inspect the full run and show you where the problems are.

Often yes — leaky ducts waste cooled air into attics and crawlspaces, so sealing them cuts that loss.

Both. Your forced-air ductwork carries heated air in the winter the same way it moves cooled air in the summer, so sealing leaks and reconnecting loose sections improves comfort and even temperatures year-round. That matters here, where homes run gas, oil, or propane heat through long cold months, and a leaky duct wastes that heat just like it wastes your AC.

If a duct has pulled apart, is crushed or has a missing or damaged vent boot, it needs repair. If the runs are connected but air escapes at the joints and seams, it needs sealing, and many jobs are both. We inspect the run first and tell you which, and we repair and seal ducts but do not clean them.

Uneven rooms, weak airflow at vents, dust returning quickly and higher energy bills are the signs. Visible gaps or separated joints in the basement or attic confirm it.

We find each leak with an inspection of the run, then seal joints and seams with mastic or foil tape rated for ductwork, reconnect sections that have separated and fasten them with proper straps, replace damaged vent boots and re-support sagging runs. Ordinary cloth duct tape dries out and fails, so it is not used. After the repair we check airflow at every register.

Leaks tend to show at joints and seams, where a branch meets the main trunk, at the boots behind registers, and at the connection to the furnace or air handler. Flex duct can also sag and pinch in an attic or crawl space. These are the places we inspect first, and they are also the places you can check yourself with the system running.

Small accessible leaks can be sealed with mastic or foil tape, and the repair holds if the surface is clean. Ordinary cloth duct tape fails within a season or two. Leaks in tight attics, behind walls or at the furnace connection, and any run that has separated, are better left to a technician who can reach and re-support them safely.

We prioritize same-day airflow and comfort calls Monday through Friday, 7:30am to 6pm, where the schedule allows, and a repair to a few accessible joints or a loose run can often be finished on the inspection visit. Larger work is quoted first. Call (518) 482-4205 or book online.

When a run is badly undersized, corroded, crushed beyond saving, or so leaky that patching will not hold. We show you what we found and explain whether a targeted repair or replacing that run is the better long-term spend. If a new system is going in anyway, ask about the ducts during central AC installation, since undersized ductwork limits any new unit.
