We come from our shop on the I-12 service road in Ponchatoula, about 77 minutes away. One honest visit that finds the real cause, with the price in writing before any work starts.


Gretna sits on the west bank of the Mississippi, right across the river from downtown New Orleans, with its historic downtown along Huey P. Long Avenue. The ground is low and the river clay holds moisture against foundations through the long humid season. Older houses with original ductwork often lose a lot of that cool air before it ever reaches the rooms.
That’s why we start every Gretna visit with a load calculation and moisture readings, then size, seal and drain the system for the house it’s in.
About 77 minutes and 59 miles from our shop on the I-12 service road by way of I-55 and I-10.

Often it’s the ducts. Leaky or undersized ducts lose cold air in the attic. We check airflow at the registers and tell you which one it is.
