Seven months of cooling in Breaux Bridge heat
Your air conditioner runs April through October here, seven months a year. Summer afternoons average 91°F, so the unit you install is not resting much between April and the first cool nights of fall.
A new central air conditioner installed here has to meet 14.3 SEER2, the federal minimum since 2023. St. Martin Parish has also logged 14 hail events and 24 damaging wind events over the past ten years, with hail as large as 2.75 inches. Whatever goes in outside your home has to stand up to that, not just the heat.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests contractors before it licenses them, and it keeps the record on file. The license belongs to the contractor, not to the job, so it is not renewed or reissued each time a crew installs a new air conditioner.
That license is what stands behind the person doing this work in St. Martin Parish. Beyond it, a new air conditioner still needs a permit from the local building office, and an inspection once it is installed, in most cities and counties. That inspection is separate from the state license and checks the installation itself, not the contractor's standing.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor measures your windows, insulation, ceiling height, and how much shade your house gets, then runs those numbers to find the tonnage that matches your home. Summer afternoons here average 91°F, and cooling that runs from April through October, an oversized unit will cool the air fast but leave it damp, and an undersized one will run nonstop and still fall behind on the hottest days. Either way you end up paying for a mistake that a proper calculation avoids.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are matched and both working, replacing just the outdoor unit can make sense. But most residential air conditioners are designed and rated as a matched pair, and putting a new outdoor unit on an old indoor coil often means the system never reaches the efficiency either part was built for. New systems installed today have to meet a federal minimum of 14.3 SEER2, and that rating only holds if the coil and condenser are matched. A contractor can check your coil's condition and age against the new unit to tell you whether it is worth keeping.
- Do HVAC contractors in Breaux Bridge need a state license to work on my home?
- Yes. Louisiana requires HVAC contractors to hold a state license, issued through the Louisiana State Licensing Board for Contractors. The license is held by the contractor, not issued per job. Installing an air conditioner also typically needs a permit from the local building office, with an inspection once the work is done, so ask whether that permit is pulled before the work starts.
