Twelve months of work, with storms on top of it
Your system does not get a break in Morgan City. It runs seven months of the year to cool the house against afternoons near 90°F, then switches over for five months of heat when nights drop to around 47°F. That is every month of the year asking something of it, and each changeover puts a new load on the parts that start it up.
Most homes here heat with electricity, so a power outage means no heat at all. Nearly half of Louisiana households lost power for at least a day in 2024, and this parish has logged 16 damaging wind events over the past ten years. When the power drops and comes back, a furnace or air handler needs to come back on by itself. If it does not, you find out the hard way, on the coldest night or the hottest afternoon.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors is the one testing and keeping records on the contractor doing this work. That license belongs to the contractor as a business, not to each job they take on, so it does not get reissued or re-checked every time someone calls for a repair.
For a repair to your heating and cooling system, that state license is what stands behind the person in your house. It means the board tested this contractor and has a record of them before they ever touched your system.

- Why is my heat not working?
- Most often it's the thermostat, a tripped breaker, or the igniter not lighting the burners. Check that the thermostat is set to heat and a few degrees above room temperature, and that nothing tripped at the breaker box. If the furnace runs but no warm air comes out, or it tries to start and shuts back off, that points to the igniter, the flame sensor, or a safety switch, and a contractor will need to look at it. With winter nights here averaging 47°F, a furnace that won't hold a flame is worth getting to quickly.
- Why is my system running but not cooling the house?
- If the blower is running but the air isn't cold, the problem is usually low refrigerant, a dirty evaporator coil, or a compressor that isn't kicking on. Check the air filter first. A clogged filter starves the coil of airflow and can ice it over, which stops cooling completely even though the system sounds fine. If the filter is clean and the air still isn't cold, that's a job for a contractor, especially with afternoons here hitting 90°F where the house can heat up fast without working cooling.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set correctly, has working batteries, and is actually calling for heat or cooling. Next check the breaker box for a tripped breaker, since a system that won't turn on at all is often an electrical issue rather than a mechanical one. Then pull the air filter and hold it up to the light. If you can't see through it, replace it, since a blocked filter can cause problems that look like bigger failures. If the system still isn't working after that, a contractor will need to diagnose it directly.
