Ductwork Repair in Rochester, NY and the Surrounding Area

Ductwork is unseen, but vital for delivering heated and cooled air throughout your home. When your ductwork is in need of repair, much of that conditioned air is being lost – and that results in decreased home comfort and an increase in your utility bills. When your ductwork is working as a perfect conduit between your home comfort equipment and your living spaces, you’ll enjoy improved comfort and better energy savings.

Common Ductwork Problems We Repair

Rochester’s mix of older housing stock, unconditioned attics, and damp basements puts real strain on ductwork, especially through our long heating season. Loose joints, crushed flex duct, and gaps where sections were never properly connected are some of the most common issues we find during a ductwork repair visit, and left alone they quietly drain efficiency from an otherwise healthy furnace or AC system.

Signs Your Ductwork Needs Repair

Uneven temperatures from room to room, especially between finished basements and upper floors, are often the first sign of a leak or disconnected duct rather than a problem with the equipment itself. Other signs to watch for include rising heating and cooling bills without a change in usage, a noticeable increase in dust around vents and registers, whistling or rattling sounds when the system runs, and musty odors that point to moisture collecting inside ducts that pass through unheated crawl spaces or attics. If a room hasn’t felt right no matter how you adjust the thermostat, disconnected or leaking ductwork is worth ruling out before replacing any equipment.

Air Duct Leak Repair & Sealing (Mastic Sealant, HVAC Foil Tape)

Once we’ve located the leaks, usually at seams, joints, and connections rather than mid-run, we don’t rely on standard cloth duct tape, which dries out and peels away within a year or two, especially in the temperature swings typical of a Rochester attic. Instead, we clean each surface and apply mastic sealant, a brush- or trowel-applied compound that cures into a flexible, airtight seal at every joint, and use HVAC-rated foil tape on accessible seams where mastic isn’t practical. For ductwork running through unconditioned spaces, we’ll also check insulation after sealing, since a well-sealed duct that’s poorly insulated can still lose heat or invite condensation. The result is a duct system that delivers the air your furnace or AC actually produces, instead of losing it in the attic.

Our Diagnostic Process for Air Duct Leaks

We start with a visual walkthrough of every accessible section: attic, basement, and crawl space, since that’s where we most often find the damage. A lot of homes in neighborhoods like Irondequoit, Greece, and Penfield were built decades ago and have had additions, finished attics, or converted garages tacked on since, which usually means the original ductwork was extended rather than redesigned. Those tie-in points are where we see the most leaks and disconnects. From there, we take a static pressure reading at the air handler to see how hard the system is working to push air through the ducts, and to physically locate leaks that aren’t visible to the eye. In finished spaces where we can’t see the ductwork directly, a thermal imaging camera helps us spot temperature differences at wall and ceiling cavities that point to a hidden leak or missing insulation.

Repair vs. Full Duct Replacement: How We Decide What's Best for Your Cooling System

Most of what we find can be repaired: sealed joints, reconnected sections, replaced flex duct where it’s crushed or torn. We lean toward full replacement when the ductwork is original to a much older home and made of unlined sheet metal that’s rusted or undersized for a modern system, when damage is spread across most of the run rather than isolated to a few joints, or when you’re already planning a new furnace or AC and the existing ducts weren’t sized correctly for it in the first place. If we can get you another decade out of well-sealed, well-insulated ductwork, we’ll say so. If patching one more leak just means you’ll be back to square one next winter, we’ll tell you that too.
