Updated pricing for NYC homeowners and building managers.
Updated pricing for NYC homeowners and building managers.
Leaky, damaged, or poorly insulated ductwork is one of the most overlooked sources of energy waste in New York City homes. The Department of Energy estimates that leaky ducts can reduce HVAC efficiency by 20-30%, meaning you are paying to heat or cool air that never reaches your living spaces. In NYC, where energy costs are already among the highest in the nation, fixing ductwork problems can yield substantial savings. Duct repair ranges from simple sealing of joints and connections to full replacement of damaged sections. This guide covers realistic pricing for all types of duct repair work in the NYC market.
| Service | Low | High | Notes |
|---|---|---|---|
| Duct Leak Sealing (mastic/tape) | $500 | $1500 | Sealing accessible joints and connections |
| Aeroseal Duct Sealing | $1500 | $3500 | Advanced aerosol sealing from inside the ducts |
| Duct Section Replacement | $300 | $800 | Replacing damaged or crushed duct runs |
| Duct Insulation | $3 | $8 | Adding insulation to uninsulated ducts |
| Full Ductwork Replacement | $3000 | $10000 | Complete replacement of all ductwork |

Duct sealing may qualify for energy efficiency incentives through Con Edison and NYSERDA programs, particularly when performed as part of a home energy audit or weatherization project. Aeroseal duct sealing specifically is recognized by many utility programs and may qualify for rebates of $200-$500.
Signs of leaky ducts include rooms that are consistently too hot or too cold, higher than expected energy bills, visible dust around vent registers, and whistling or hissing sounds when the HVAC runs. A professional blower door test can precisely measure duct leakage.
In most cases, yes. Sealing duct leaks typically reduces heating and cooling costs by 15-25%, which means the investment pays for itself within 1-3 years. The savings are greatest in homes where ducts run through unconditioned spaces.
Despite its name, standard duct tape is not appropriate for sealing HVAC ducts — it deteriorates quickly from temperature changes. Use aluminum foil tape or mastic sealant instead. These are the materials professional HVAC technicians use for long-lasting duct sealing.
