Stop Wasting Cool Air: Duct Repair & Sealing in New Orleans
Stop Losing Cool Air: Duct Repair & Sealing in New Orleans
Cooled air is expensive to make and easy to lose. In a lot of New Orleans homes, ductwork runs through hot attics or damp crawl spaces, and gaps, cracks, and disconnected joints let a surprising amount of that cooled air escape before it ever reaches a vent. Duct repair and sealing fixes that leak point, so the air your system works hard to condition actually makes it into the rooms you live in. Rob’s Air Conditioning & Heating has spent 35+ years working on homes across the New Orleans metro area, and fixing leaky ductwork is one of the most overlooked ways to make a home more comfortable without replacing a single piece of equipment.
Ductwork does not fail all at once. It loosens at the joints over time, insulation wears thin, and small cracks widen as a house settles, especially in the older shotgun-style and raised homes common across our neighborhoods. None of that shows up as an obvious problem the way a broken system does. Instead, it shows up as a system that runs constantly, rooms that never quite feel right, and an electric bill that keeps climbing even though nothing else has changed.
A lot of homeowners assume a high bill or an uneven house means the system itself is failing. Often the equipment is working fine, it is just fighting a losing battle against ductwork that is leaking conditioned air into an attic or under the house before it ever reaches a vent. Industry estimates suggest a typical duct system can lose a meaningful share of the air moving through it to leaks, which means your system may be working overtime just to make up for air that never gets where it is supposed to go.
Signs of Leaky Ducts in Your New Orleans Home
Homes and light commercial spaces across the metro area, from Harvey to Metairie, Kenner, and Chalmette, deal with a sSome of the clearest signs of leaky or damaged ductwork:
- One room is always warmer or colder than the rest of the house, no matter what the thermostat says
- Your energy bills have crept up over time without an obvious reason
- Airflow feels weak at certain vents, even though the system sounds like it is running normally
- Dust seems to build up faster than it used to, especially near vents or in certain rooms
- You notice a hissing or whistling sound coming from the attic, closet, or crawl space
- Rooms feel humid or stuffy even when the system is running
If a couple of these sound familiar, there is a good chance your ductwork has a leak somewhere in the system, even if you cannot see or hear it directly.
In an older New Orleans home, ductwork often runs through spaces that take a beating, attics that swing between scorching heat and humidity, and crawl spaces that stay damp for most of the year. Both conditions are hard on duct seams, insulation, and the metal or flex duct material itself, which is part of why leaks show up here more than in newer homes built in drier climates.
How We Repair & Seal Ductwork
Our technicians start with an inspection of your full duct system, checking joints, seams, and connections for gaps, disconnections, and damaged insulation. In some cases we use a duct pressure test, a simple diagnostic that measures how much air your system is actually losing, to confirm where the leaks are before any work begins.
Once we know where the problems are, we seal joints and seams with mastic, a thick, paint-like sealant that holds up far better over time than standard tape, and reinforce loose connections with proper mechanical fasteners. Where insulation has thinned or come loose, we replace it so your ducts hold temperature the way they are supposed to instead of losing it to the surrounding attic or crawl space air. For ductwork that is too damaged to seal effectively, we repair or replace the affected sections rather than patching over a bigger problem.
The goal is straightforward: get the air your system conditions to actually reach your living spaces, instead of leaking out along the way. Sealed, properly insulated ductwork also means your system does not have to run as long or as hard to hit the temperature on your thermostat, which is often where homeowners notice the difference first, a system that used to run constantly finally gets a break.

Duct Repair & Sealing FAQs
How do I know if my ducts are leaking?
Common signs include rooms that are always warmer or colder than the rest of the house, rising energy bills without an obvious cause, weak airflow at certain vents, and a hissing or whistling sound near your attic or crawl space. If any of that sounds familiar, Book Now and we will take a look.
Can duct leaks really affect my energy bill?
Yes. A duct system with leaks can lose a meaningful share of conditioned air before it ever reaches a vent, which means your system has to run longer and harder to reach the temperature on your thermostat. Sealing those leaks often shows up directly on your energy bill.
What is duct sealing, exactly?
Duct sealing means closing up gaps, cracks, and loose joints in your ductwork, usually with a thick sealant called mastic, so conditioned air stays inside the ducts instead of leaking into your attic or crawl space.
Do I need to replace my ductwork, or can it just be sealed?
Most duct systems can be repaired and sealed rather than replaced. We only recommend replacing sections that are too damaged, crushed, or deteriorated to seal effectively.
How long does duct repair and sealing take?
Most duct repair and sealing jobs are same-day service. The exact time depends on how much of your duct system needs attention, and we will walk you through the scope before we start.
Will sealing my ducts help with humidity in my home?
Often, yes. Leaky ducts running through a humid attic or crawl space can pull in extra moisture along with lost air. Sealing those leaks helps keep humidity where it belongs, outside your conditioned living space.
