Ten months of work a year on your system in Ruston
Your system runs most of the year here. Heat from November through March, cooling from May through September, only a couple months off in between. Winter nights average 37°F, so the furnace or heat pump cycles on and off most of the night, every night, for five months straight. Summer afternoons hit 92°F, and the AC answers back for another five.
That much run time wears on the parts that start the cycle and the parts that move the air. Louisiana sees its share of wind, 51 damaging wind events and 5 winter storms in the last ten years in this area, and power loss follows. Close to half of Louisiana households lost power for a day or more in 2024. When the power drops and comes back, most systems restart on their own, but a system already struggling to light or cool can fail right at the moment you need it most.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests and records the people who hold this license. It is not tied to any one job or address, and it does not get reissued each time a contractor takes on new work. The board's record is on the contractor, not on this repair.
For a heating and cooling repair, that license is what stands behind the work. It tells you the contractor was tested and is on record with the state, not just the business but the person doing the job.

- Why is my heat not working?
- Most of the time it comes down to the thermostat, the igniter, or the power supply. Check the thermostat first and make sure it's set to heat and a few degrees above room temperature. If you have a gas furnace, listen for it trying to start. A furnace that clicks but never lights usually has a bad igniter or flame sensor. If it's electric heat, a tripped breaker will keep it from running at all. With winter nights here dropping to 37°F on average, a furnace that won't hold a flame needs a contractor out soon rather than waiting it out.
- Why is my system running but not cooling the house?
- If the blower is running but the air isn't cold, check the air filter first. A filter clogged with dust chokes off airflow across the coil, and the coil can ice over when that happens. Look at the outdoor unit too. If the fan out there isn't spinning, or if you can see ice on the refrigerant lines, that points to a refrigerant problem or a failing compressor. With summer afternoons here reaching 92°F, a system that's iced over needs to be shut off and thawed before a contractor can properly diagnose it.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Confirm it's set to the right mode and the batteries aren't dead. Check the breaker panel next, since a tripped breaker will shut a system down completely and looks like a bigger problem than it is. Pull the air filter and hold it up to the light. If you can't see through it, replace it, since a blocked filter causes both weak heat and weak cooling. If the system still won't run right after that, a contractor will need to look at the parts inside the unit itself.
