We come from our shop on the I-12 service road in Ponchatoula, about 83 minutes away. One honest visit that finds the real cause, with the price in writing before any work starts.


Chalmette sits on the east bank of the Mississippi in St. Bernard Parish, with low ground and river silt and clay underneath. The parish levee system runs the whole perimeter. Many homes here were rebuilt after major storms, and new walls on an old, damp slab still need an A/C that dries the air, not just one that cools it.
That’s why we start every Chalmette visit with a load calculation and moisture readings, then size, seal and drain the system for the house it’s in.
About 83 minutes and 73 miles from our shop on the I-12 service road by way of I-12, I-10 and LA 47.
When a home inspector someday asks who installed this and when, the answer is in your file.
On-site look at the system, ductwork, electrical service and the house itself. A Manual J load calculation to ACCA standards. A written quote with your equipment options and the total price, with no high-pressure sales.
Mechanical permits filed with the parish or town, and the rough-in and final inspections scheduled with the inspector. Permit fees are in the quote.

Load calculation, AHRI certificate, permit numbers, inspection sign-offs, serial numbers for warranty registration and the start-up readings. Ready if you ever sell the house.
Newer, tighter construction holds moisture in, and an oversized system shuts off before it dries the air. A load calculation shows whether your system fits the house.
Yes. Chalmette and Arabi get the same crew and the same prices. We handle the parish permit and inspections.
