Seven months of Louisiana heat wears on a system

Your air conditioner runs from April through October here, seven months of the year. On summer afternoons averaging 91°F, it is not just cycling on and off, it is running long stretches to keep up. That kind of runtime adds hours to the compressor and the fan motor that a milder climate would never ask of them.

A tune-up checks the parts that long runtime wears on. A technician checks the refrigerant charge, since a system low on refrigerant runs longer and harder than it should. They check the capacitor, which weakens under long runtimes and is a common reason a compressor won't start. They clean the condenser coil outside, because a dirty coil makes the whole system work harder to move the same heat.

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 Louisiana State Licensing Board for Contractors tests and records the contractor, not each job the contractor takes on. That license is tied to the business, so it stays in place across every service call rather than being issued fresh for each one.

For a maintenance visit on an air conditioner, that state license is what stands behind the person coming to your house. If the work involves opening the refrigerant side of the system, the technician also needs EPA Section 608 certification, which is a federal requirement that applies in every state, not something Louisiana adds on top.

What does AC maintenance include?
A technician checks refrigerant levels, cleans the condenser coil, tests the capacitor, and looks over the electrical connections. They also check that the coil isn't icing up and that the thermostat is calling for cooling correctly. Cleaning the outdoor coil matters here, since hail and wind can leave grit and debris packed into the fins. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, so that part of the job is never optional to skip.
How often does an air conditioner need maintenance?
Once a year, before the season it works hardest. Here that means getting it checked before April, since the system runs from April through October and summer afternoons average 91°F. A dirty coil or low refrigerant charge makes the unit work harder to hit the same temperature, and that strain adds up over seven months of daily use.
Is AC maintenance worth it?
Yes, especially in a place where the system runs seven months straight. A maintenance visit is also when a technician catches a bent coil fin or other storm damage, and that matters here, where 48 damaging wind events and 14 hail events have been recorded over the past ten years. Catching that kind of damage early keeps it from turning into a bigger repair.
