Kenner runs its system almost all year
A home in Kenner needs heat or cooling 11 months of the year. Summer afternoons average 90°F from April through October, seven months of the compressor running most days. Winter is short, just November through February, but nights still average 47°F and the heat has to keep up.
A new system here has to be sized for that long cooling season first, since that is the bigger share of the year. It also has to hold up through the weather that comes with living here. The area has seen 38 damaging wind events over the ten years from 2015 to 2024, and in 2024 about half of Louisiana households went at least 24 hours without power. Most systems come back on by themselves once power is restored, and that is worth knowing before one goes in.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests and licenses the contractor, not the job. That means the person or company doing your installation carries a license tied to them, and the state has a record of who they are. It does not mean the board signs off on this particular system going into your home.
That part comes from a permit. In most cities and counties, a heating and cooling installation like this one needs a permit from the local building office, and an inspector checks the work once it is in. The license tells you the contractor was tested. The permit and inspection tell you this job, in your house, was done to code.

- When should I replace my HVAC system?
- Once your system is old and needs a repair, replacement is usually worth a hard look. Watch for the signs adding up together, not just one. Higher bills, a system that runs longer to hit the same temperature, or a repair that costs a big share of a new unit. Here, your air conditioner works 7 months a year and your furnace 4, so an aging system gets pushed hard most of the year with little rest between seasons.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed years apart may not match well, since they share the same blower and ductwork and work as one system. If your furnace is still young and running fine, there's no reason to replace it just because the air conditioner failed. A contractor can look at the age and condition of both and tell you honestly whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment first, then sets the new furnace, air conditioner or heat pump in place and connects it to your ductwork, refrigerant lines, gas line or electrical circuit depending on what the system needs. After that comes testing, checking refrigerant charge, airflow, and that the thermostat is talking to the system correctly. In most cities and counties this work needs a permit from the local building office, with an inspection once it's done. Louisiana also requires the contractor doing the work to hold a state license through the Louisiana State Licensing Board for Contractors.
