Duct Sealing & Repairin Freehold, NJ

You pay to heat and cool the air in your house. Then a big share of it leaks out of the ducts before it ever reaches the room you are sitting in. Novus Mechanical seals and repairs leaky duct systems across Freehold and Monmouth County, and we test the ducts first so the work targets the leaks that actually matter.

Most of the leaking happens where you never look: inside walls, up in the attic, down in the crawlspace. The air slips out through gaps at the joints, bad connections, and seams that were never sealed right. One room stays stuffy. Another never warms up. The system runs longer to make up the difference, and your bill climbs.

How do I know if my ducts are leaking?

The signs are easy to feel. A room that never gets comfortable no matter where you set the thermostat. Bills creeping up for no clear reason. Rooms that go dusty fast. Those all point to duct leaks, but feeling them is not the same as measuring them.

The only way to know for sure is to test. Novus uses duct leakage testing to put a calibrated fan on your duct system and measure exactly how much air it loses, and roughly where. That number is the difference between sealing the real problem and guessing. We measure first, then we fix. No blind quotes.

How we seal and repair leaky ducts

Sealing ducts is not a roll of duct tape. That is the irony of the name: regular tape dries out and peels off in a couple of years, especially in a hot attic. Real duct sealing uses mastic, a thick paste that gets brushed over the joints and seams and stays flexible for the long haul.

Here is what the work covers:

  • Sealing the joints, seams, and connections where conditioned air escapes
  • Reconnecting ducts that have pulled apart or were never connected right
  • Repairing crushed, torn, or disconnected runs in the attic and crawlspace
  • Mastic and proper mechanical fasteners on the connections, not tape that fails

We focus on the leaks the test flagged. Once the sealing is done, the air your system makes actually reaches the rooms instead of dumping into the attic.

What is duct optimization?

Sealing stops air from leaking out. Optimization makes sure the air that stays in the ducts goes where it should. Those are two different problems, and a duct system can be leak-free and still deliver poorly.

It comes down to sizing and balance. Ducts that are too small choke airflow. Long, twisty runs starve the rooms at the end. Dampers set wrong send too much air to one part of the house and not enough to another. Duct optimization corrects the sizing, the connections, and the balance so every room gets the air it needs.

Novus measures airflow room by room and adjusts the system across Freehold and Monmouth County. If your ducts are part of a bigger reroute or your home needs new runs, that crosses over into ductwork installation, and we will tell you honestly which one your house actually needs.

What you get when the ducts are right

Comfort is the first thing you notice. The room that never matched the rest of the house finally holds its temperature. The system stops running all day to chase rooms it could not reach.

Lower bills follow. When the air you paid for stays inside the ducts, the system works less to keep the house comfortable. The equipment runs shorter cycles and lasts longer because it is not fighting leaks every hour.

Duct sealing also pairs with the bigger picture of how tight your home is. Leaky ducts and a leaky building envelope often show up together, which is why we sometimes pair the duct test with blower door testing to see the whole house at once. Test, seal, verify. That is the order that saves you money instead of wasting it.
