Air Duct Sealing • Home Comfort
Air Duct Sealing in Southeast Louisiana
Stop paying to condition your attic.
Your HVAC system may be doing its job while leaky ductwork lets conditioned air escape before it ever reaches your rooms. Duct Daddy identifies, measures and seals duct leakage to help your HVAC system deliver the air you're already paying to heat and cool.
Serving Greater New Orleans, the Northshore and Southeast Louisiana.
The problem
Your AC May Not Be the Problem.
Equipment gets blamed for symptoms the duct system is causing. When a duct system leaks, part of the air you already paid to condition never reaches the rooms you live in.
- Uneven temperatures from room to room
- Rooms that never stay comfortable
- Conditioned air escaping into attics and other unconditioned spaces
- Long HVAC runtimes
- Poor airflow at certain registers
- Higher-than-expected utility costs
- Unnecessary workload on equipment that is doing its job
Leaky duct system
A horizontal attic unit feeds a sheet-metal plenum, then flex runs branch out to each room. Leakage is rarely one hole — air escapes at the plenum seams, at each takeoff collar and at the register boots.
Air lost at plenum seams, takeoff collars and boots
Sealed duct system
With the plenum seams, collars and boots sealed, more of the conditioned air travels the full run and arrives in the rooms you actually live in.
Air stays in the ducts and reaches every register
Closet unit, leaky chase
Common around here: the air handler sits in a closet and the supply runs straight up a wall chase into the attic. Every joint on that path — chase, ceiling penetration, plenum, boots — is a place air leaves.
Air lost in the chase, at the ceiling and at every boot
Closet unit, sealed chase
Sealed at the chase, the ceiling penetration, the plenum seams and each boot, the same system delivers the conditioned air into the rooms instead of the attic.
Air stays in the chase and reaches every ceiling register
Start with the symptom
Your AC problem might be an air-delivery problem.
Most homeowners don't search for duct sealing — they search for the thing that's bothering them. Pick the symptom that matches your house and read the honest explanation, including the causes that have nothing to do with ductwork.
One room stays hot
A single bedroom or upstairs room that never keeps up with the rest of the house — and what actually causes it.

Long runtimes are not automatically a fault — here is how to tell the difference between working hard and losing air.
Read the guide →Weak airflow at the vents
Barely any air at a register — and how to tell restriction, leakage and physical damage apart.
Read the guide →House feels humid
The temperature is fine but the house feels sticky. What controls indoor humidity, and where ducts come into it.
Read the guide →New AC, same problems
New equipment is usually connected to the existing duct system. Here is what a replacement does and does not change.

Summer bills climb for a lot of reasons. One of them can be measured instead of guessed at.

How it works
Four steps. One measured outcome.
Every project follows the same sequence, and it ends with numbers.
- 01
Measure
Evaluate the duct system and establish existing leakage.
- 02
Prepare
Prepare and protect the HVAC system and registers for the sealing process.
- 03
Seal
Use professional duct-sealing equipment and processes to address leakage throughout the duct system, including leaks that may be difficult to access manually.
- 04
Verify
Test the system again and document the measured difference.
We don't just say your ducts are tighter. We measure the difference.
