If we can’t fix it, you don’t pay
In many Marrero homes the AC is fine — the ductwork is the problem. Leaky, undersized, or sweating ducts waste cooled air, run up bills, and leave rooms uneven and humid. Tegridy Air inspects, seals, and repairs ductwork across Marrero and West Jefferson. Call (504) 414-8655. Family-owned, 30+ years of combined experience.
Signs of duct trouble in Marrero homes
- Rooms that never match the thermostat.
- High bills with an AC that runs constantly.
- Dust and a humid, stuffy feel even with the system on.
- Ducts sweating in hot attics, dripping onto insulation.
- Crushed, kinked, or disconnected flex duct.
Why ducts fail here
Most homes route ducts through an attic that bakes all summer. The heat dries out old mastic and tape until joints leak, and humidity condenses on uninsulated runs and breeds mold. Every leak dumps cooled air into the attic and makes the AC work harder — sealing and insulating those runs is one of the highest-return fixes in this climate.
How we fix it
We inspect the full duct system, find leaks and disconnects, and seal joints with mastic and metal tape — never cloth duct tape, which fails in Louisiana heat. We re-secure sagging runs, replace damaged sections, and insulate ducts that sweat.
Duct repair pricing in Marrero
- Duct inspection / leakage check: $80–$150
- Targeted sealing & minor repairs: $350–$900
- Larger re-runs or replacement: quoted after inspection
You approve a written price first, and sealed ducts often pay for themselves within a couple of cooling seasons.
Serving Marrero
We cover the neighborhoods off Ames Boulevard and near Bayou Segnette and the rest of 70072 across West Jefferson — plus nearby Harvey and Westwego.
Duct repair FAQs
How do I know my ducts leak?
Uneven rooms, high bills, and dust are the signs; an inspection confirms and locates them.
Seal or replace?
Most homes need sealing and insulation; we replace only crushed or failed sections.
Is it worth it?
Cutting 20–30% duct loss is one of the fastest ways to lower a summer bill.
Will it help humidity and dust?
Yes — sealing keeps humid attic air, dust, and moisture out of your system.
What Our Customers Say About Us
Honest Voices, Honest Service
“Absolutely amazing experience! With the recent heatwave my ac was just not keeping up. I was able to schedule a same day appointment for a system checkup. They quickly found the problem and fixed it. Within the hour I had a fully functioning ac again. The technicians were incredibly friendly and explained everything they were doing and described the problems in a way I could easily understand. The price was incredibly reasonable. After work was complete they even stayed a while to ensure everything was working as intended. I can’t recommend these guys enough. They will be the only company I call from here on out”
“Very professional, great service. I can’t say enough about how great these guys are. They responded right away and had my air blowing the coldest it’s ever been. I will recommend them to anyone who needs A/C work done.”
“I called them on a service call. Because my HVAC was not working. I had a quick response and they sent out a technician. He diagnosed it and repaired it within the hour. Quality service and reasonably priced. I would definitely use them again!”
“Alex and his crew always do a great job, super friendly, and are very fair with their pricing. They are thorough and make sure to explain what they are doing, why they are doing it, and how it will help. They never push products or services on me and will happily answer any questions. My ac went out yesterday, I called at ~4:40pm and they showed up a few minutes later. They resolved the issue quickly and explained what had happened. Highly recommend.”
