Our Ductwork Services

Duct Inspection & Leakage Testing

We pressurize your duct system and measure air loss from leaks. Results are documented so you know exactly how bad the problem is before committing to a solution.

Duct Sealing & Aeroseal

Hand-mastic sealing at all accessible joints plus Aeroseal injection for hard-to-reach ductwork. Most NJ homes lose 20-30% of conditioned air through duct leaks.

Duct Cleaning

Removes accumulated dust, debris, mold spores, and pest intrusions from supply and return runs. Required before adding air purifiers or UV systems.

Duct Replacement & Redesign

When ductwork is beyond sealing, collapsed, or contaminated, we replace and redesign. All sizing is calculated from ACCA Manual D.

Ductwork FAQ

How do I know if my ducts are leaking?
The clearest signs are uneven temperatures between rooms, high energy bills relative to your neighbors, and supply registers that feel weak. We can test your system with a blower door to measure exactly how much air is being lost.
How often should ducts be cleaned?
Every 3-5 years for most homes, or after any renovation, rodent infestation, water intrusion event, or HVAC system replacement.
Can duct sealing reduce my energy bills?
The EPA estimates 20-30% energy savings in homes with significantly leaky ductwork. Real-world savings depend on your current leak rate. We test before and after so you know the actual improvement.
What is Aeroseal duct sealing?
Aeroseal injects aerosolized sealant into a pressurized duct system. The particles flow to leak points and build up until the leak is sealed, reaching joints and seams that are physically inaccessible by hand.
