Ductwork Installation & Repair in Brooklyn, NY

Ductwork Built Around Brooklyn Buildings

Brooklyn ducts live in basements with 6-foot ceilings, in soffits framed around a furnace that is long gone, and in attics with no insulation. A lot of houses in Marine Park and Bay Ridge got central air in the 80s with flex duct stapled to the joists and never sealed. A lot of brownstones in Park Slope have no ducts at all and a homeowner deciding between new ductwork and a ductless system. We do both, and we will tell you which one fits the house.

Our Ductwork Process, Step by Step

1. 1

   Airflow test. Static pressure at the air handler, airflow at every register, temperature at the supplies and returns.

2. 2

   Design. A Manual D duct layout sized to the equipment, with return air that actually matches the supply.

3. 3

   Fabrication. Sheet metal trunks and branches cut to the house, flex duct only where a rigid run cannot go.

4. 4

   Installation. Trunks hung level, branches with gentle turns, dampers at the takeoffs, every joint sealed with mastic, insulation on runs through unconditioned space.

5. 5

   Balance and test. Dampers set room by room, airflow retested, the numbers written down and handed to you.

Ductwork Services for Brooklyn Homes

New duct systems. For central air conversions, additions and gut renovations. Trunk and branch, or a high-velocity small-duct system for a finished house with no room for soffits.

Duct repair. Disconnected runs, crushed flex, rusted trunks, boots that pulled away from the floor.

Duct sealing. Mastic and foil tape on every joint. Not cloth duct tape, which fails in a year.

Duct insulation. R-6 or R-8 wrap on runs through attics, crawlspaces and unheated basements.

Return air upgrades. Added returns and larger return grilles so the blower stops straining.

Airflow balancing. Dampers and register adjustments so the top floor and the first floor land within a couple of degrees of each other.

Dryer and bath exhaust. Rigid metal runs that actually exhaust outside.

What Affects the Cost of Ductwork in Brooklyn

New or repair. A full duct system for a three-story house is a multi-day job. Sealing and a new return is often one day.

Access. Open basement joists are quick. Finished ceilings mean cutting, patching and painting.

Material. Sheet metal costs more than flex and lasts the life of the house.

Equipment. A new duct system is often paired with AC Installation & Replacement or Furnace Installation & Replacement, and the quote covers both.

Heat pump airflow. Heat pumps move more air than furnaces, so ducts sized for a 1985 furnace often need upsizing before Heat Pump Installation & Repair.

Local Conditions We Engineer Around in Brooklyn, NY

Low basements. Trunk lines routed along the walls, not across the middle of the room.

Party walls. No duct chases through the shared wall. Soffits run along the inside.

Plaster ceilings. Register cuts made cleanly and patched, not hacked.

Radiator houses. Adding ducts for cooling only, while the steam system keeps heating. The ducts are sized for AC airflow.

Attic runs. Insulated and sealed, because a Brooklyn attic hits 130 degrees in August.

What to Expect When You Hire Brooklyn HVAC Company

An airflow test before the quote, a layout drawing and a fixed price, clean sheet metal work, every joint sealed, dust protection in the living space, and a final balance with the numbers in writing. Indoor Air Quality upgrades like media filters and UV lights install into the same ductwork while we are there.
