A system that runs almost year round
In Orleans Parish there's barely an off season. Summer afternoons average 90°F and that heat holds from April through October, seven months of cooling. Winter is shorter, November through March, with nights averaging 46°F. Between the two, a heating and cooling system here is doing real work all twelve months.
Most homes in Louisiana heat with electricity, so the condenser and the heat strips or heat pump both carry load through the year, not just one system resting while the other runs. Storms are part of the picture too. Orleans Parish has logged 35 damaging wind events over the past ten years, and close to half of Louisiana households went at least 24 hours without power in 2024. A new system here needs to be sized for the heat it will fight most months, and put in by someone who thinks about what a storm and a lost power supply will do to it.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests and records the contractor, not the individual job. That means the license follows the company doing your work, whoever they send to your house.
For an installation like this, in most cities and parishes the job also needs a permit from the local building office, plus an inspection once the work is done. That inspection is what checks the finished install, the license alone does not cover it.

- When should I replace my HVAC system?
- Once your system needs repairs more winters and summers than not, or the repairs keep adding up, replacement is usually the better move. Age matters too. A furnace or air conditioner working hard through 7 months of cooling and 5 months of heat here wears faster than one that gets a real break. If your system is old and the next repair is a big one, that's the point to stop patching it.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, and here's why. Your furnace and air conditioner share the same blower and often the same coil, so replacing one without the other can mean the new unit is stuck matched to an old, less efficient partner. A mismatched system also tends to run less efficiently than a matched one. A contractor can look at both and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment in place and connects it to your ductwork, refrigerant lines, gas or electric line, and condensate drain. They'll check the ductwork for leaks or sizing problems while they're in there, since new equipment connected to bad ductwork won't perform the way it should. In New Orleans, this job needs a permit from the local building office, and an inspector checks the work when it's done. The contractor handles the permit and schedules that inspection as part of the job.
