Twelve months of work, then a storm knocks the power out
Your system in Tangipahoa Parish doesn't get an off season. It heats from November through March and cools from April through October, which leaves almost nothing in between. Summer afternoons averaging 91°F push the compressor hard for seven months straight. Come winter, nights averaging 42°F bring the heat pump or furnace back online for a shorter stretch, but the switch between the two puts real wear on whatever runs the system.
Most homes here heat with electricity, so when the power goes out, so does the heat or the AC. Almost half of Louisiana households lost power for at least 24 hours in 2024, and this parish has logged 48 damaging wind events over the past ten years. A system that comes back on by itself after an outage is one thing. A capacitor or control board that took a hit during the storm is another, and that's when you notice the air isn't moving right when the power comes back.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests and licenses HVAC contractors before they can take on work like this. That license belongs to the contractor, not to the job, so it stands behind everything they do, not just the one repair at your house.
For a heating and cooling repair, that license is what backs up the work. Louisiana puts its oversight into that license itself, tested and held by the contractor, rather than splitting it across separate local rules.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that it has power or fresh batteries. If the thermostat looks fine, check your breaker panel, since a tripped breaker will cut power to the furnace or air handler without any other warning. Most homes here heat with electricity, so a tripped breaker or a problem at the outdoor unit or air handler is a common cause. If power is not the issue, the igniter or a safety switch inside the furnace may be keeping it from starting, and that calls for a contractor to check.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the indoor coil, and when that coil cannot get enough air across it, the air coming out of your vents warms up even though the system is running. Next check the outdoor unit and clear away any leaves, grass clippings or debris stacked against it, since it needs open airflow to move heat outside. If the filter is clean and the outdoor unit is clear, the system may be low on refrigerant or have a failing part, and a contractor will need to check it with gauges to know for sure.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first, since a thermostat set wrong or with dead batteries looks exactly like a broken system. Check your breaker panel for anything tripped. Check the air filter and replace it if it is gray or clogged, since a blocked filter causes both weak heating and weak cooling. Look at the outdoor unit and clear away anything piled against it. If the system still is not working after that, a licensed contractor will need to diagnose it, and in Louisiana that means someone licensed through the Louisiana State Licensing Board for Contractors.
