HVAC Built for Mandeville's Lakefront Homes
Mandeville is one of the Northshore’s gems — historic Old Mandeville right on the Lake Pontchartrain seawall, oak-lined streets, and newer neighborhoods spreading north toward Fontainebleau and the Tammany Trace. That lakefront setting is beautiful, but it comes with serious humidity, salt-tinged air off the lake, and the same June-through-November hurricane season as the rest of South Louisiana.
Old Mandeville’s older and historic homes often weren’t built for modern central air, so we frequently recommend ductless mini-splits that cool well without tearing into original woodwork. Right on the seawall and lakefront, salt and moisture wear on outdoor condenser coils faster, so we watch coil condition and unit placement closely. For the larger newer homes north of town, we focus on properly-sized, high-efficiency systems that keep whole-house comfort even and energy bills sane.
Across Mandeville and St. Tammany Parish — Old Mandeville, the lakefront, and the neighborhoods near Fontainebleau State Park and the Tammany Trace (70448, 70471) — we handle AC repair and replacement, ductless installs for historic homes, hurricane-season tune-ups, and high-efficiency upgrades. Call us at (504) 414-8655.
- If we can’t fix it, you don’t pay
In many Mandeville homes — especially larger ones on wooded lots — the ductwork quietly wastes a big share of the cooling you pay for. Leaky or sweating ducts leave rooms uneven and the air humid. Tegridy Air inspects, seals, and repairs ductwork across Mandeville and St. Tammany Parish. Call (504) 414-8655. Family-owned, 30+ years of combined experience.
Signs of duct trouble in Mandeville homes
- Rooms that never match the thermostat — common in larger Northshore floor plans.
- High bills with an AC that runs constantly.
- Dust and a humid, sticky feel even with the system on.
- Ducts sweating in hot attics, dripping onto insulation.
- Long flex-duct runs that have sagged, kinked, or pulled apart.
Why Mandeville ductwork fails
Most homes here route ducts through an attic that bakes all summer, and lakefront humidity makes it worse. The heat dries out old mastic and tape until joints leak, while moisture condenses on uninsulated runs and breeds mold. Every leak dumps cooled air into the attic and makes the system 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 Mandeville
- 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.

Duct repair FAQs
How do I know my ducts leak?
Uneven rooms, high bills, and dust are the signs; an inspection confirms and locates the leaks.
Seal or replace?
Most homes just 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 Northshore 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
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
Drew Buller
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.
michael bordelon
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!
Dave H
After buying an older home I was completely burned through a cycle of faulty or half way work being performed and/or companies that were pushing outrageous sales and upgrades for simple repairs needed. I was emotionally overwhelmed and one month, several thousand dollars, and 3 HVAC companies later still without a working AC. I made a plead on Nextdoor for anyone to help me and recommend a trustworthy AC person and then found these guys and decided to give them a shot. I am SO grateful that I did! I called in the afternoon and they arrived within 2 hours. They checked everything— discovered a simple issue that could not previously be identified, fixed that issue, which was the fault of another service tech, getting my system back running and informed me about other details of my system. They charged me only a service call fee and changed my air filter before leaving. I was almost in tears. My AC has been running perfect ever since! I wish there were more companies like this in every trade— honest, quality inspection and work, take pride in what they do, not trying to just rip people off.
Courtney Coco
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.
