Alexandria asks a new system to work most of the year
Cooling runs April through October here, seven months of summer afternoons near 92°F. Heat only takes over for the other five, November through March, with winter nights averaging 41°F. That leaves almost no season where the system just sits idle. A new system has to handle both sides well, not just one.
Most homes here heat with electricity, so a winter power outage means no heat at all, and Louisiana saw a lot of outages last year, with half of households losing power for at least 24 hours in 2024. The storm record over the past ten years is mostly wind, 59 damaging wind events against a single winter storm. Whatever gets installed will spend most of its life fighting heat, and needs to be ready for wind and the outages that come with it.

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 a record of who holds one. That license belongs to the contractor, not to the individual job, so it does not expire or get reissued each time a crew installs a new system.
For an installation like this one, the license is what stands behind the contractor's qualifications, but the work itself still goes through the local building office. In most cities and parishes, putting in a new furnace, air conditioner or heat pump needs a permit, and the finished job gets an inspection before it is considered done. That inspection is what checks the gas connections, the wiring and the refrigerant lines were put together correctly, separate from whatever the state license already tells you about the contractor.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when the unit is old enough that another breakdown is just a matter of time. If a contractor is quoting a major repair, like a compressor or a heat exchanger, that's usually the point to weigh it against replacing the whole system instead. Homes here run the air conditioner from April through October and the furnace from November through March, so a failing system means a long stretch without reliable comfort either way. A contractor can look at the age and condition of your equipment and tell you whether another repair still makes sense.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it usually makes sense to do both together rather than one now and one later. A furnace and air conditioner installed at the same time are matched to work as a system, and pairing an old unit with a new one can mean the new one never runs at its best. It also means going through the permit and inspection process once instead of repeating it for a second job later. If your furnace and air conditioner were installed years apart, a contractor can tell you whether it still makes sense to replace them together or wait.
- 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 the ductwork, the electrical supply, the refrigerant lines and, for a furnace, the gas line or venting. Once it's connected, they test it, checking refrigerant charge, airflow and that the thermostat is talking to the system correctly. In most cities and counties, a furnace, air conditioner or heat pump replacement needs a permit from the local building office, and the job gets inspected once it's done. Louisiana also requires the contractor doing the work to hold a state HVAC license, so that's worth confirming before the job starts.
