Seven months of cooling in Thibodaux heat
Your air conditioner runs from April through October here, seven months of the year. Summer afternoons average 90°F, so the system is working hard for most of that stretch, not just a few weeks in midsummer.
A new central air conditioner installed today has to meet a federal minimum of 14.3 SEER2. Lafourche Parish has also seen its share of hail and wind, sixteen hail events and sixteen damaging wind events over the past ten years, with hail up to 3.5 inches. The outdoor unit sits exposed to that, so it needs to be installed to hold up 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 job. So the license tells you the person or company doing your installation had to prove they know the trade before the state let them work in it, and the board keeps that record on file. It does not mean someone checks this particular installation.
That check comes from the local building office. Most cities and parishes require a permit for an air conditioner installation and an inspection once it is done, and that inspection is what confirms the work at your house was done right, separate from whatever the state already knows about the contractor.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not from the square footage of your house alone. A contractor looks at your insulation, your windows, how many rooms face the afternoon sun, and your attic before landing on a number. With summer afternoons here running near 90°F for seven months of the year, an undersized unit will run constantly and still not keep up, while an oversized one cools the air fast without pulling the humidity down, so leaving it to a proper calculation matters more than guessing from a chart.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were installed together and matched to each other, replacing only the outdoor unit usually means replacing the whole system anyway, because a new condenser paired with an old coil rarely performs the way it should and can shorten the life of the new equipment. New central air conditioners have to meet a 14.3 SEER2 minimum now, and older coils weren't built to work with that standard. A contractor can check your existing coil and tell you whether it can carry over or not.
- Do HVAC contractors in Thibodaux 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. For an AC installation, you'll also need a permit from the local building office and an inspection once the work is done.
