Seven months of heat wears on a system that never gets a break
Your air conditioner runs from April through October here, with summer afternoons averaging 91°F. That means the compressor is cycling on and off almost every day for seven months straight. That kind of schedule wears on specific parts. The capacitor that starts the compressor weakens. The contactor that switches it on pits and sticks. The coil has to shed heat into air that is already hot, and dirt on it makes that harder.
A tune-up checks the refrigerant charge, tests the capacitor and contactor, and clears the coil and drain line. It catches the part that is close to failing before the next stretch of hot afternoons does it for you.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Louisiana requires HVAC contractors to hold a state license.
The state board tests contractors before they get that license and keeps a record of who holds one. It covers the person or company doing the work, not each individual visit, so the same license applies whether they're back for a checkup next year or a bigger repair down the road.
For a maintenance visit, that license is what stands behind the work in St. Charles Parish. If the technician needs to check refrigerant levels or get into the sealed side of your air conditioner, federal law also requires them to hold an EPA Section 608 certification, the same rule that applies in every state.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil, tests the capacitor, and checks the electrical connections for signs of wear. They also check the thermostat is calling for cooling correctly and check airflow across the indoor coil. Anything touching the refrigerant side has to be done by someone with EPA Section 608 certification, which is a federal requirement everywhere. In Louisiana the contractor sending the technician also has to hold a state license through the Louisiana State Licensing Board for Contractors.
- How often does an air conditioner need maintenance?
- Once a year is standard, ideally before the cooling season starts. Here that means getting it done before April, since homes run the AC from April through October, seven months straight. A system that runs that long each year, through afternoons averaging 91°F, works harder than one that only runs a few months, so it benefits from being checked before the heavy months start rather than partway through them.
- Is AC maintenance worth it?
- Yes, because most AC failures trace back to something that gets caught in a checkup, like a weak capacitor or a dirty coil, before it causes a breakdown. A system here also runs longer stretches under harder conditions than in milder climates, given seven months of cooling and summer afternoons averaging 91°F. On top of that, this area has seen hail and damaging wind, including 26 wind events over the past ten years, so a yearly check is also a chance to catch damage to the outdoor unit before it turns into a bigger problem.
