Eleven months of work, then a storm knocks out the power
Your system in Luling barely gets a break. Cooling runs April through October, seven months, then heat takes over November through February, another four. Only a short stretch in spring and fall gives the compressor and the burner both a rest.
Summer afternoons average 91°F, so the compressor carries that load for most of the year, and the run time wears on it. More than half of homes here heat with electricity, so when the power goes, the heat goes with it. Louisiana sees a lot of that. Nearly half of households in the state lost power for at least a full day in 2024, and this parish has logged 26 damaging wind events over the past ten years. When the power comes back on, most systems restart on their own, but a compressor or a fan motor that took a hit during the outage will not.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests HVAC contractors before issuing this license, and it keeps a record of who holds one. The license belongs to the contractor, not to the job, so it is not issued or checked separately for each repair.
For a repair on your heating and cooling system, that state license is what stands behind the person doing the work. It means the state tested this contractor and has them on record before they ever open up your system. That accountability is what you have here, since the license covers the contractor generally rather than this specific repair.

- Why is my heat not working?
- Most often the thermostat is calling for heat but the furnace isn't responding, or it's cycling on and shutting off before the house warms up. If the furnace has a pilot light or igniter, that's the first thing to check, since a dirty flame sensor or a burnt out igniter will stop it from lighting at all. If you heat with electricity, check the breaker panel first, since a tripped breaker will cut power to the whole system with no warning. A contractor can test the igniter, the flame sensor and the control board to find which one failed.
- Why is my system running but not cooling the house?
- The blower is moving air, but something between the air handler and your rooms isn't doing its job. A dirty filter is the most common cause, since it chokes off airflow across the coil and the coil can freeze up as a result. Low refrigerant from a leak will also leave the air blowing but barely cool, and that's not something you can fix by yourself. Check the filter first. If it's clean and the air is still warm, the system needs a contractor to check the refrigerant charge and the coil.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to heat or cool as needed and that the batteries aren't dead. Check the breaker panel for a tripped breaker, and check the filter, since a filter clogged with dust will choke airflow and can make a working system act like a broken one. If the outdoor unit has power but the fan isn't spinning, or you hear it humming without turning, don't try to force it. That's a job for a contractor licensed by the state of Louisiana.
