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
Mandeville’s long Northshore cooling season runs your AC hard from spring well into fall, and lakefront humidity is tough on equipment. A Tegridy Air tune-up keeps your system efficient and heads off the breakdown that always seems to land on the hottest day. Service across Mandeville and St. Tammany Parish — book at (504) 414-8655. Family-owned, 30+ years of combined experience.
What a Mandeville tune-up covers
- Condensate drain cleared and flushed — humidity here clogs them fast, and a backed-up line shuts the system down.
- Condenser coil washed of lake moisture residue, pollen, and debris so the unit can shed heat.
- Refrigerant charge and leak check.
- Capacitor and electrical test — the part most likely to fail in peak heat or after a surge.
- Blower, thermostat, and airflow check; filter inspected.
Twice a year on the Northshore
With cooling season stretching most of the year, one annual visit isn’t enough here. We recommend a spring tune-up before summer and a fall check on the heat. Near the lakefront, the spring visit matters most — moisture and salt-tinged air corrode and foul outdoor coils faster than inland, and a clean coil is money straight off your summer bill.
Pricing & maintenance plans
- Single AC tune-up: $89–$149
- Maintenance plan (seasonal visits + priority service): ask for current pricing
A maintenance plan covers both seasonal visits and gives you priority scheduling when the first heat wave has the whole Northshore calling at once.

- Honest reporting, not a padded list of “needed” repairs.
- Same-day and 24/7 help if a tune-up turns up something urgent.
- Family-owned, with plans and financing available.

AC tune-up FAQs
How often should I service it?
Twice a year — spring and fall — or at least every spring.
Does it lower my bill?
Usually — a clean coil and correct charge cut runtime, which is most of your summer power use.
The AC works fine — why bother?
Maintenance prevents the mid-summer failure; that’s the whole point.
Does the lake really affect my unit?
Yes — lakefront moisture corrodes coils and contacts faster, so regular cleaning pays off here.
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.
