Ductwork Repair, Sealing & Installation in New Jersey
Leaky, undersized or poorly designed ductwork is the hidden reason many New Jersey homes have a sweltering second floor, weak airflow and high utility bills no matter how good the furnace or air conditioner is. Heating Cooling NJ tests, repairs, seals, redesigns and installs ductwork throughout the state.
Typical homes lose 20 to 30 percent of conditioned air through duct leaks in attics, crawlspaces and basements. Fixing that is often the most cost-effective comfort upgrade available.
Signs of Duct Problems
Rooms that never reach the thermostat setting, dust that accumulates quickly, whistling or rattling from registers, a system that runs constantly, visible gaps or disconnected flex duct in the attic, and a basement or attic that feels conditioned are signs that ductwork needs attention.
Duct Testing and Sealing
We measure static pressure and airflow, inspect accessible ductwork and identify leaks at joints, boots and plenums. Sealing with mastic and approved tape, replacing crushed or kinked flex duct, insulating ducts in unconditioned spaces and adding returns where they are missing can transform how a system performs.
Duct Design and Installation
For additions, renovations and first-time central air installations we design duct systems using Manual D principles, sizing trunks and branches for correct airflow to every room. We install sheet metal, flex and ductboard systems and high-velocity small-duct systems for homes where conventional ducts will not fit.
Zoning
Motorized dampers and a zone control panel allow different areas of the house to be controlled independently, which solves the second-floor problem in two-story homes and reduces energy use in rooms that are rarely occupied.

Ductwork Repair & Installation FAQs
How do I know if my ducts leak?
A static pressure and airflow test plus a visual inspection reveals leakage. Dusty rooms and uneven temperatures are common symptoms.
Is duct sealing worth it?
In most homes with ducts in attics or crawlspaces, yes. Energy savings and comfort gains are significant.
Can you add ducts to an older home?
Yes, using conventional, high-velocity or a mix of ducted and ductless approaches.
Do you insulate ducts?
Yes. Ducts in unconditioned spaces should be insulated to prevent energy loss and condensation.
Can zoning fix my hot upstairs?
Zoning combined with proper duct sizing is the most reliable fix for two-story temperature imbalance.
