A system that works almost every month here
New Iberia only gets a break from heating or cooling for a few weeks a year. Winter nights average 46°F from December through February, mild enough that a lot of homes lean on electric heat rather than gas. Summers run the opposite direction, with afternoons averaging 90°F for seven months, April through October. A new system has to handle both ends without much rest between them.
The parish has seen 25 damaging wind events over the past ten years, and close to half of Louisiana households lost power for at least a day in 2024. When the power comes back, most heating and cooling equipment starts up on its own, but a new installation is worth planning around the chance of an outage in the first place.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests and records the contractor, not the job. That license stays with the business across every project it takes on, so the credential you're checking is the company's, earned once and kept on file with the state.
For an installation like this, the license is what backs the contractor doing the work, but the local building office still has its own part. In most cities and parishes, putting in a new furnace, air conditioner or heat pump needs a permit and an inspection once the work is done. That inspection is what checks the installation itself, separate from whether the contractor is licensed to do it.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they should, or when the system can't keep up on the coldest nights or hottest afternoons. A furnace or air conditioner nearing the end of its life tends to run longer to hit the same temperature, and you'll notice higher bills before you notice a breakdown. Homes here need heat from November through March and cooling from April through October, so a system that struggles in either stretch is worth replacing before it fails outright. If a contractor has already repaired the same part more than once, that's usually the sign to stop patching it.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and air conditioner installed together are matched to work as one system, so pairing a new air conditioner with an aging furnace, or the other way around, can mean the newer unit never runs at its full efficiency. Homes here need heat from November through March and cooling from April through October, so both sides of the system are working most of the year. If only one has failed and the other is still young, a contractor can tell you whether replacing just the one makes sense for your setup.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump and sets the new equipment in place, then connects it to your ductwork, refrigerant lines, gas line or electrical circuit depending on what the system needs. After that, they test the system to make sure it's heating and cooling correctly and check the refrigerant charge and airflow. In most cities and counties this work needs a permit from the local building office, and an inspector checks the job once it's done. Louisiana also requires the contractor doing the work to hold a state license, which covers the contractor rather than the individual job.
