Gonzales runs its system almost year round
Seven months of cooling and five months of heat means your system in Gonzales gets almost no rest. Summer afternoons average 91°F, and the compressor runs long hours to keep up, which wears on the parts that keep it running. In winter, nights average 44°F, cold enough that the heat still has to cycle on and off through the night.
Most homes here heat with electricity, so when the power goes out, the heat goes with it. Nearly half of Louisiana households lost power for at least a day in 2024, and Ascension Parish has seen 30 damaging wind events over the past ten years. A system that already runs hard most of the year has less room to handle a hard restart after an outage.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors is the body that issues this license. It tests the contractor before granting it and keeps a record of who holds one. The license belongs to the contractor, not to any single job, so the same license that got tested once covers this repair and every other job that contractor takes on.
For a repair on a heating and cooling system, that state license is the thing accountable for the work. It is not something issued for this particular repair, it is a record that the contractor doing it has been tested and is known to the state.

- Why is my heat not working?
- Most of the time it comes down to the thermostat, the power to the unit, or the igniter. Check that the thermostat is set to heat and the temperature is above room temperature. Check the breaker for the furnace and the switch that looks like a light switch near the unit, since that shuts off power for service and gets bumped off by accident. About two thirds of homes here heat with electricity, so a tripped breaker after a storm is worth checking first. If power and the thermostat both check out and the furnace still will not fire, a contractor needs to look at the igniter or the flame sensor.
- Why is my system running but not cooling the house?
- If air is moving but it is not cold, the problem is usually the airflow across the coil or the refrigerant charge. Start with the filter. A clogged filter starves the coil of air and it can freeze over, and once that happens the system blows warm air even though it is running. Check the outdoor unit too. If the fan is not spinning or it is caked with grass and debris, it cannot get rid of the heat it is pulling from the house. If the filter is clean and the outdoor unit is clear and you are still getting warm air, the refrigerant charge or the compressor needs a contractor's gauge to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Confirm it is set to heat or cool as needed, the batteries are good, and the temperature setting actually calls for the system to run. Check the filter next and replace it if it is gray or clogged, since restricted airflow causes problems in both winter and summer. Check the breaker box and any power switch near the indoor and outdoor units, especially after a storm. Louisiana sees its share of damaging wind, and a breaker that tripped during one is an easy fix compared to anything mechanical. If all of that checks out and the system still is not heating or cooling right, a licensed contractor will need to diagnose it further.
