A system that works nearly every month of the year

Cooling runs April through October here, seven months of afternoons near 91°F. Heat takes over November through March, five months of nights that average 42°F. That's twelve months of one system or the other carrying the load, with little time off between them.

Most homes here heat with electricity, so the same power supply carries a new system through both seasons. Nearly half of Louisiana households lost power for at least a day in 2024, and this parish has seen its share of damaging wind over the past ten years. Whatever gets installed should come back on by itself once the power is restored, with nothing left half finished.

Louisiana requires HVAC contractors to hold a state license.

The state board tests contractors before they can hold this license, and the license belongs to the contractor, not to any single job. That means the same license has to be good on your installation as on every other job that contractor takes on, and the board has a record of who holds it.

For a heating and cooling installation, that license is what stands behind the work itself. In most cities and counties, including here, replacing a furnace, air conditioner or heat pump needs a permit from the local building office, and the office inspects the work once it is done. That inspection is separate from the state license and checks the installation itself, not the contractor's credentials.

When should I replace my HVAC system?
Once your system is breaking down more than once a season, or a contractor tells you the compressor or heat exchanger has failed, it is time to replace rather than repair. An older system also tends to run longer to do the same job, and that shows up in your power bill. Homes here need cooling April through October and heat November through March, so it helps to plan a replacement before the season it fails in, not during it.
Should I replace my furnace and air conditioner at the same time?
If both are original to the house and close in age, replacing them together usually makes sense. Your furnace and air conditioner share a coil and an air handler, and mismatched equipment does not run as well as a matched system. If one unit has years of life left, a contractor can size a new one to work with what is staying. Ask about matching before you decide, since it changes what the installation involves.
What happens during an HVAC installation?
A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, then connects it to your ducts, refrigerant lines, gas line or electrical circuit as needed. After that comes charging the refrigerant, testing the thermostat, and checking airflow at the vents. Replacing this kind of system needs a permit from the local building office and an inspection once the work is done.
