Twelve months of work, on and off the coast
Your system doesn't get a real break here. Cooling runs April through October, seven months, with afternoons near 90°F pushing the compressor hard most days. Heat takes over for the other five months, with winter nights averaging 42°F, so the system is starting up in the cold within weeks of shutting down from the heat. That back and forth wears on the parts that start it each time it cycles on.
Most homes in Pascagoula heat with electricity, so when the system falters, the house is what tells you. The area has logged 29 damaging wind events over the past ten years, and in 2024 close to a third of Mississippi households lost power for a full day or more. A unit that loses power mid-cycle and comes back on wrong can keep running while it struggles to heat or cool. If your air feels weak or the house won't hold temperature after the power blinks, that's usually where to look first.

Mississippi requires HVAC contractors to hold a state license.
That license covers the contractor, not the job itself. The same license that lets someone install a heating and cooling system also covers coming back to repair one, so there is no separate credential to look for on a repair call.
For this job, that state license is what stands behind the person working on your system. Mississippi puts the accountability there, on the contractor, rather than on the job.

- Why is my heat not working?
- Most of the time it comes down to the thermostat, the power supply, or the igniter. Check that the thermostat is set to heat and the temperature is above room temperature. Look at your breaker panel too, since a tripped breaker will shut the whole system down. If the thermostat and power both check out, the igniter or a safety switch inside the furnace is a common next place for the problem to sit, and that's a job for a contractor to open up and check.
- Why is my system running but not cooling the house?
- If air is moving but it is not cold, the problem is usually low refrigerant, a dirty filter blocking airflow, or ice built up on the coil. A clogged filter starves the system of air and can freeze the coil over time, which stops it from cooling even though the fan keeps running. Check the filter first since that is the one thing you can rule out yourself. Refrigerant and coil issues need a licensed contractor, since Mississippi requires one to work on the system itself.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to the right mode and the batteries aren't dead. Check the filter next and replace it if it's gray or clogged, since a blocked filter causes both heating and cooling problems. Then check your breaker panel for anything tripped. With 29 damaging wind events recorded here over the past ten years, a breaker trip after a storm is common and worth ruling out before assuming the system itself has failed.
