Seven months of cooling changes what you need
Morgan City runs its air conditioner April through October, seven months a year. Summer afternoons average 90°F, so the unit you install is doing real work most of the year, not just on a handful of hot days.
A new central air conditioner installed here has to meet the federal efficiency minimum of 14.3 SEER2. Beyond that number, this area has also logged 16 damaging wind events and 6 hail events over the past ten years, with hailstones up to 1.75 inches. Whatever goes in outside is going to sit through weather like that.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tested this contractor before handing out the license, and the board keeps a record of who holds one. That license belongs to the contractor, not to this particular job, so it travels with the business from one installation to the next.
An air conditioner installation in most cities and parishes also needs a permit from the local building office, with an inspection once the work is done. That inspection is what checks the installation itself, the wiring, the refrigerant lines, the way the unit is set, separate from whatever the state license already says about the contractor.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, ceiling height, insulation, window placement, and how much shade it gets, not just a rule of thumb. A contractor works this out with a load calculation, which looks at your specific house rather than guessing from size alone. With summer afternoons here averaging 90°F, getting this number right matters more than in milder climates. An oversized unit cools the air fast but shuts off before it pulls the moisture out, and an undersized one runs constantly and still can't keep up on the hottest days.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and indoor coil need to be matched, so replacing only one can mean the new part never runs at its rated efficiency. If your system is old enough that the outdoor unit is failing, the indoor coil has likely logged the same years and hours. A contractor can check whether your existing coil and indoor components will pair properly with a new outdoor unit before you decide. Any new outdoor unit installed today also has to meet the federal minimum of 14.3 SEER2, which is worth factoring in if your indoor coil is much older.
- Do HVAC contractors in Morgan City 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. That license covers the contractor as a business, not the individual job, so it's worth confirming the contractor's license before work starts rather than assuming it covers whoever shows up. Installing an air conditioner also typically needs a permit from the local building office, with an inspection once the work is finished.
