Seven months of cooling, five of heat, and storms that cut the power
Your air conditioner is the machine doing the real work here. Summer afternoons average 91°F, and the system runs from April through October to keep up with it. That is seven months of the compressor cycling on and off, and long runtimes wear on the capacitor and the contactor first. You notice it as air that is not as cold as it used to be, or a unit that runs and runs without the house catching up.
Winter asks less of the system, but nights still average 42°F from December through February, and most homes here heat with electricity. Louisiana sees far more damaging wind than winter storms, and in 2024 close to half of households in the state lost power for a day or more. What matters after an outage is whether your system comes back on by itself once the power does. A unit that stays dark after the lights come back on needs a look.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests and records the people who hold this license. It is not tied to your address or to this one job. It stays with the contractor and covers the work they do across the state, so the same license applies whether they are in Baton Rouge or anywhere else in Louisiana.
For a repair on a heating and cooling system, that license is what stands behind the person working in your house. It covers the contractor, not the specific repair, so the credential you are relying on is theirs, earned before this job and carried into it.

- Why is my heat not working?
- Most of the time it's the igniter, a tripped limit switch, or the thermostat set wrong or dead on batteries. If your furnace runs on gas, check that the gas valve is on and the pilot or igniter is doing its job before you assume the worst. Most homes here heat with electricity, so check the breaker box too, since a tripped breaker is the simplest thing to rule out. Winter nights here average 42°F, so a furnace that won't fire needs a contractor to look at it soon rather than wait it out.
- Why is my system running but not cooling the house?
- The system running but not cooling usually comes down to a dirty filter blocking airflow, low refrigerant from a leak, or a frozen evaporator coil. A frozen coil often traces back to that same airflow problem, so check the filter first and replace it if it's clogged. If the filter is clean and air is still barely coming out of the vents, the coil may be icing over inside the unit, and running the system longer will not fix that on its own. Summer afternoons here average 91°F, so a system that runs without cooling needs a contractor to find the actual cause rather than keep running.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to heat or cool as needed, the batteries are good, and the temperature setting actually calls for the system to run. Next check the breaker box for a tripped breaker, since a system that won't turn on at all is sometimes that simple. Then look at the filter. A filter clogged with dust restricts airflow and can cause problems that look like bigger issues, from weak cooling to a coil that ices up. If none of that explains what you're seeing, a licensed contractor can diagnose the actual problem.
