Seven months of cooling, in Denham Springs heat
Your air conditioner runs April through October here, seven months, and on a lot of those afternoons it's working against 91°F. That's a long stretch for a compressor to hold a house cool.
That kind of run time is what a tune-up checks for. Low refrigerant makes the compressor work harder to hit the same temperature. A dirty coil can't shed heat as well, so the system runs longer to do the same job. Weak electrical connections heat up faster the longer they're under load. None of that stops your AC from running today. It's what turns into a breakdown partway through the season if nobody looks at it first.

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.
Louisiana licenses HVAC contractors through the Louisiana State Licensing Board for Contractors. That license belongs to the contractor, not to any single job, so the same license covers a maintenance visit, a repair, or a full installation.
For a maintenance visit on your air conditioner, that license is what stands behind the person in your home. If the technician needs to open the refrigerant side of the system to check the charge, they also need EPA Section 608 certification, the same as any technician in the country doing that work. That certification says they are trained to handle refrigerant safely. It is separate from the state license, and it is not something Louisiana issues.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the condensate drain, since a clogged drain line can back up and shut the system down or leak into the house. They also check airflow, look at the filter, and check that the thermostat is calling for cooling correctly. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, so that part of the job cannot be skipped or done by just anyone.
- How often does an air conditioner need maintenance?
- Once a year, before the cooling season starts. Homes in Denham Springs run their AC from April through October, seven months of the year, with summer afternoons averaging 91°F, so the system works hard for most of the year. A spring checkup catches a weak capacitor or a dirty coil before it fails on a 91°F afternoon rather than after.
- Is AC maintenance worth it?
- Yes, because most AC breakdowns trace back to something maintenance would have caught, like a failing capacitor or a coil so dirty the system can't shed heat. A unit that runs seven months a year here does not get much rest between seasons to reveal small problems on its own. Catching those problems early, before a 91°F afternoon, is what the yearly checkup is for.
