Ductwork Repair and Sealing in Rensselaer, NY
A good furnace or AC cannot fix a bad duct. Repair for leaking joints, disconnected runs, crushed flex duct and missing returns.

What we fix
Leaks and disconnects
Joints that have pulled apart in the attic or basement, sealed with mastic or foil tape rated for ducts, not cloth duct tape.
Airflow problems
Undersized or crushed runs, closed dampers and rooms with no return. Measured, traced and corrected.
Insulation
Supply ducts running through cold attics and crawl spaces, insulated so the heat and cool reach the room.
New runs
Extending ductwork to finished basements, additions and rooms the original system never reached.

Signs your ducts need work
- One or two rooms are always too hot or too cold.
- The house is dusty soon after cleaning.
- You can see gaps, sagging flex duct or old tape in the attic or basement.
- Weak airflow from some vents and strong airflow from others.
- Bills went up but the system seems to run fine.
Ductwork questions
How do I know if my ducts are leaking?
Rooms that never get comfortable, a dusty house, high bills and a furnace or AC that runs long are the common signs. In attics and basements you can often see it: disconnected joints, crushed flex duct, or tape that has dried out and fallen off.
Why is one room always hotter or colder than the rest?
Usually the duct to that room is too small, too long, disconnected or uninsulated where it runs through an attic or crawl space. Sometimes the room simply has no return. Tracing the run shows which one it is.
Is duct tape the right way to seal ducts?
No. Cloth duct tape dries out and lets go within a few years. Joints should be sealed with mastic or foil tape rated for ductwork, and runs in unconditioned attics should be insulated.
Can you add ductwork to a house that has radiators?
Sometimes, using closets, attics and basements for the runs. When there is no good path, a ductless mini-split or a small-duct high-velocity system is the cleaner option. We look at the house and lay out the choices.
Should my ducts be cleaned?
Duct cleaning helps after renovation dust, a rodent problem or visible mold. It is not a fix for poor airflow. Leaks, undersized runs and missing returns cause far more comfort problems than dirt does.
