Air Duct Repair, Sealing & Replacement Across Rochester and Victor, NY.
Dalton Heating & Cooling repairs leaking, crushed, disconnected and worn-out ductwork in homes and businesses across Rochester, Victor and the surrounding towns. Your furnace, air conditioner or heat pump can only deliver the comfort it produces if the ducts carry that air to every room. When a joint separates in the basement or a flexible duct collapses in the attic, heated and cooled air escapes into unconditioned spaces, and the rooms farthest from the equipment become cold in winter and warm in summer.
Most duct problems in Greater Rochester homes are caused by age, installation conditions and the regional climate. Sheet metal trunk lines in many basements have been in service for decades, flexible duct in attics is often compressed or damaged, and joints loosen as ducts expand and contract through long heating seasons and humid summers. Our technicians repair both metal and flexible ductwork in basements, attics, crawl spaces and garages, and we verify proper airflow before completing every service.

Duct problems are often difficult to detect, because most ductwork is concealed behind walls, above ceilings and under floors. When ducts leak or separate, they can:
ENERGY STAR estimates that the typical home loses 20 to 30 percent of the air moving through its duct system to leaks, holes and poorly connected ducts. During Rochester winters, this means paying to heat unconditioned areas such as attics and crawl spaces rather than your living areas.

Dalton Heating & Cooling has been family-owned and operated in Victor since 1989, and much of our work comes from referrals and repeat customers. We look at your whole system, because ductwork and equipment work as one. Uneven heat and short cycling often trace back to duct leaks during furnace repair, and weak airflow or a frozen coil found during AC repair can start in the ducts. We recommend a repair when a repair will resolve the problem, and we provide honest guidance when replacement is the better option.
Our expert team is ready around the clock to handle any urgent heating and cooling problems around the clock, so a failed duct connection during cold weather can be addressed promptly.
Serving Victor, Rochester, and surrounding communities, Dalton is a trusted, family-owned business committed to putting your needs first.
We repair and seal ductwork using only durable, HVAC-rated materials, including mastic sealant, foil tape and galvanized sheet metal, backed by professional service and expert advice.
Whether it’s duct sealing, a disconnected run or a damaged section, most ductwork repairs are completed in a single visit, often within a few hours.
Every repair begins with an accurate diagnosis. A cold bedroom can be caused by a disconnected run, a closed damper, a crushed flexible duct or an undersized return, and each requires a different solution. Our team follows a structured process for every ductwork repair:
Inspect the System: A technician inspects every accessible duct run in the basement, attic and crawl space, and checks the furnace or air handler, filter and registers.
Measure Airflow: We compare airflow and temperature at the registers to find which rooms are losing air and where along the run it is escaping.
Explain What We Found: You get a clear explanation of each problem and a firm upfront price before any work begins.
Make the Repairs: We seal, reconnect, replace, re-hang or insulate as needed, using mastic and foil tape designed for HVAC applications rather than standard cloth duct tape, which deteriorates over time.
Verify the Results: We run the system, recheck airflow at the problem rooms and review the completed repairs with you before the visit is finished.
Most duct repairs are finished in a single visit, often within a few hours. If your ducts also require professional cleaning, we can combine the repair with our duct cleaning service in Rochester so the system is both clean and sealed in one visit.
If you notice more than one of the following signs, schedule a ductwork inspection before considering furnace or air conditioner replacement:
Uneven Room Temperatures: One or two rooms are always colder in winter or warmer in summer than the rest of the house.
Weak Airflow at Vents: Some registers deliver noticeably less air than others, even with the blower running at full speed.
Rising Energy Bills: Heating and cooling costs continue to rise without any change in how the system is used.
Extra Dust and Musty Smells: Dust settles quickly after cleaning, or a musty, insulation-like smell appears when the heat or AC comes on.
Noisy Ducts: Whistling, rattling or banging from the ducts when the system starts or stops.
Visible Damage: Gaps, loose tape, crushed flex duct or rust on ducts in the basement or attic.
Dalton Heating & Cooling repairs every part of your duct system, from a single loose joint to a full trunk line.
Ductwork is repaired by HVAC contractors, who work on both the ducts and the heating and cooling equipment they connect to. Dalton Heating & Cooling repairs sheet metal and flexible ductwork in homes and businesses across Rochester, Victor and the surrounding towns. Because leaking ducts can look like a furnace or air conditioner problem, our technicians check both during the same visit.
Most ductwork can be repaired. Leaks at joints and seams, disconnected runs and short crushed sections are repaired without replacing the whole system. Replacement is worth considering when ducts are rusted through in several places, flexible duct is brittle throughout, or the ducts are undersized for a new furnace, air conditioner or heat pump.
Common signs include rooms that never reach the set temperature, weak airflow at some vents, excess dust and rising energy bills. Visible gaps, loose tape or crushed flexible duct in the basement or attic also indicate leaks. A technician can confirm the location of leaks by inspecting the duct runs and measuring airflow at each register.
Banging or popping usually occurs when sheet metal ducts expand and contract as the system starts and stops. It can also be caused by undersized ducts, high air pressure in the system, or loose and unsupported sections. Our technicians identify the cause and correct it by re-securing, reinforcing or modifying the affected ductwork.
Condensation forms when warm, humid air contacts the cold surface of an air conditioning duct, which is common in Rochester basements, attics and crawl spaces during summer. The most effective solution is to seal the duct leaks and insulate the ducts with a vapor barrier. Reducing humidity in the space also helps prevent rust, water damage and mold.
The price depends on how many leaks or damaged sections need attention, where the ducts run (an open basement is more accessible than a confined attic or a finished wall), whether sections need replacing or only sealing, and whether insulation is needed. Replacing ductwork costs more than repairing it, which is why we always evaluate repair first. We inspect the system and provide a firm, upfront quote, so the price you approve is the price you pay.
