Eleven months of work, then a storm knocks out the power
Your system in Caddo Parish barely gets a break. Summer afternoons hit 93°F and push the AC hard from May through October. Then winter nights drop to an average of 38°F and the furnace takes over from November through March. Eleven months out of the year, something in your system is running to keep the house comfortable.
More than half of homes here heat with electricity, so when the power goes out, the heat goes with it. That happens more than you'd expect. Nearly half of Louisiana households lost power for a day or longer in 2024, and this parish has seen 279 damaging wind events and 7 winter storms over the last ten years. A system that runs almost year round and loses power without warning is a system that needs to come back on right when you need it.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors is the body that tests and records HVAC contractors in this state. Passing that exam and holding the license is what puts a contractor on the board's books. The license belongs to the contractor, not to any single job, so it does not get reissued or checked off each time a repair is done.
For a repair on a heating and cooling system in Caddo Parish, that state license is the credential behind the work, since Louisiana licenses the contractor rather than the job itself.

- Why is my heat not working?
- Start with the thermostat. If the screen is blank or won't hold a setting, check the batteries before anything else. If power is reaching the thermostat, the next common failure is the igniter on a gas furnace. It wears out over years of use and simply stops lighting the burners. A tripped breaker or a switch near the furnace that got bumped off will cause the same silence, so check both before assuming the worst. Winter nights here average 38°F, so a furnace that won't start is worth getting looked at quickly rather than waiting.
- Why is my system running but not cooling the house?
- Check the filter first since that's the one thing you can fix yourself. Pull it out and hold it up to a light. If you can't see light through it, replace it. A dirty filter chokes off airflow across the coil, and a coil that can't get airflow will ice over. If the filter is clean and the air from the vents feels warm or barely moving, the coil may be frozen or the system may be low on refrigerant from a leak. Either of those needs a contractor to check. Summer afternoons here reach 93°F, so a system that isn't cooling right won't keep up for long.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to cool or heat as needed and not switched to fan only. Check the filter next and replace it if it's visibly dirty, since a clogged filter can cause problems that look like bigger failures. Check the breaker panel for anything tripped, and look for a power switch near the indoor or outdoor unit that may have been switched off. If the system still isn't working after that, a licensed contractor can diagnose what's actually wrong. Louisiana requires HVAC contractors to hold a state license, so ask before any work begins.
