Eleven months of work, most years
A new system in Luling only gets a break for a few weeks a year. Cooling runs April through October, seven months, with summer afternoons averaging 91°F. Heat takes over November through February, when winter nights average 46°F. That is eleven months of the year when the system is doing one job or the other.
Most homes here heat with electricity, so the same power that keeps the furnace or heat pump running is the power a storm takes out first. This parish has seen 26 damaging wind events over the past ten years, and close to half of Louisiana households lost power for at least a day in 2024. Whatever gets installed here has to hold up to long stretches of heat and cold, and start back up on its own when the power does.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests contractors before they can hold this license, and the board keeps a record of who holds one. That license belongs to the contractor, not to any single job, so it does not expire when this installation is finished.
For a heating and cooling system installation, the license is what stands behind the person doing the work, but the local building office still has a part in this job. In most cities and counties here, putting in a new furnace or air conditioner needs a permit, and the work gets inspected once it is done. That inspection is separate from the state license and it is what checks the installation itself, not just who performed it.

- When should I replace my HVAC system?
- Replace it when repairs get more frequent, when the unit is old, or when it can't keep up on the hottest or coldest days. A system that breaks down every summer is telling you something, even if the next fix is small. Age matters too. A furnace or air conditioner nearing the end of its expected life will keep costing more to hold together, and homes here need cooling from April through October, so a system that struggles is one you will be dealing with for most of the year. If you are unsure whether to repair again or replace, a contractor can look at the unit's condition and give you a straight answer for your situation.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, yes, it usually makes sense to replace both together. A furnace and air conditioner installed at the same time tend to wear out around the same time, and they often share parts like the blower and ductwork, so pairing old equipment with new can cause problems that neither system was designed for. That said, if one unit is significantly newer, replacing just the older one can be the right call. A contractor can look at both systems and tell you whether they should go together or separately.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment in place and connects it to the ductwork, refrigerant lines, gas or electric line, and thermostat. Once everything is connected, the system gets tested to make sure it is heating and cooling correctly and running safely. In most cities and counties, this work needs a permit from the local building office, along with an inspection when the job is done. That inspection is there to confirm the installation meets code, which matters for both safety and for how the system performs down the line.
