HVAC Built for Gretna and the West Bank
Gretna sits on the West Bank of the Mississippi River, just across from downtown New Orleans, and it's the seat of Jefferson Parish. Historic Gretna and McDonoghville are full of older homes — many with original ductwork and tight mechanical spaces — while the neighborhoods toward Terrytown and the Westbank Expressway run a mix of mid-century and newer builds. River humidity and a long cooling season keep HVAC systems working hard year-round.
In Gretna's older homes, forcing in oversized ductwork often does more harm than good, so we'll recommend a ductless mini-split or a right-sized central system when it actually fits the house — no upsells. With the West Bank's hurricane and storm-surge exposure every June through November, we also push storm-ready installs and seasonal tune-ups so your system doesn't quit when the heat (or a storm) hits.
Across Gretna and the West Bank — historic Gretna, McDonoghville, and the Westbank Expressway corridor (70053, 70056) — we handle AC repair and replacement, ductless installs for older homes, hurricane-season tune-ups, and high-efficiency upgrades to ease your Entergy bills. Call us at (504) 414-8655.
If we can’t fix it, you don’t pay
A lot of Gretna's older homes are running AC systems well past their prime — and on the Westbank, an inefficient unit shows up fast on your summer bill. Tegridy Air installs and replaces AC across Gretna and West Jefferson with right-sized designs, up-front quotes, and financing. Call (504) 414-8655. Family-owned, 30+ years of combined experience.
When it's time to replace
- The system is 10–15+ years old and repairs keep adding up.
- It runs on R-22, now phased out and pricey to service.
- Bills climb every summer while the house never gets comfortable.
- It can't keep up with the humidity, leaving rooms damp.
Sizing for older Gretna homes
Many Westbank homes are older and were retrofitted for central air, so existing systems are often the wrong size or paired with tired ductwork. An oversized AC short-cycles and leaves the air clammy; an undersized one runs nonstop. We do a real load calculation for your home and check the ductwork and electrical so the new system fits the house — and for older homes with no good duct path, a ductless mini-split is often the cleanest, most efficient answer.
Installed pricing in Gretna
- Standard-efficiency central AC (replacement): $5,500–$8,500
- High-efficiency / variable-speed: $8,500–$13,000+
- Ductless mini-split (single zone): $3,500–$6,500
Final price depends on size, SEER2, ductwork, and any electrical work. Financing is available; old-unit removal and refrigerant recovery are included.

AC installation FAQs
Can you add AC to an older home without good ducts?
Yes — a ductless mini-split avoids major duct runs and works well in older Gretna houses.
How long does it take?
Most replacements are a one-day job; ductwork or electrical changes can add time.
What efficiency should I get?
With our long cooling season, a step up in SEER2 usually pays back in summer savings — we'll show you the numbers.
Is financing available?
Yes, on qualifying systems.
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.”
