Eleven months of work a year, with storms in between
Your system in Gulfport gets almost no rest. Heat runs November through March, cooling runs May through October, and that leaves one month where it can sit idle. Summer afternoons averaging 90°F push the compressor hard for six straight months, and most homes here heat with electricity, so the same system carries both jobs.
Harrison County has seen 53 damaging wind events over the last ten years, and 30% of Mississippi households went at least 24 hours without power in 2024. A system that loses power and comes back on usually restarts fine on its own, but a storm that knocks out a breaker or damages a line outside can leave you with no heat on a 42°F night or no cooling when it's 90°F out. When your system won't start after the power comes back, or it runs constantly without keeping up, that's wear catching up with it, not just the weather.

Mississippi requires HVAC contractors to hold a state license.
The State Board of Contractors tests contractors before issuing that license, and it keeps a record of who holds one. The license belongs to the contractor, not to any single job, so it stays with them from one repair to the next rather than being issued fresh each time.
For a repair to a heating and cooling system, that license is what stands behind the work. It tells you the state has tested this contractor and keeps a record of them, which is the protection Mississippi offers on a job like this.

- Why is my heat not working?
- Most of the time it comes down to power, gas supply, or the thermostat calling for heat and not getting an answer. Check the thermostat first and make sure it's set to heat and the temperature is above room temperature. If your system uses electric heat, check the breaker panel, since a tripped breaker will shut the whole system down. If you smell gas or the furnace won't ignite after a few tries, stop and call a contractor rather than keep resetting it. With most homes here relying on electric heat, a power issue is often the first place to look, especially after a storm.
- Why is my system running but not cooling the house?
- The blower can be moving air while the compressor outside isn't running, so you feel air but it's not cold. Go outside and check whether the outdoor unit is on. If the fan and compressor are both off while the indoor blower runs, that points to the outdoor unit, the breaker feeding it, or the thermostat wiring. A dirty filter can also choke off airflow enough that the house never catches up, so check that next. If the outdoor unit is running and you still don't get cold air, that's worth having a contractor look at rather than waiting, especially with afternoons here reaching 90°F.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it, and the filter before anything else. A dirty filter blocks airflow and can make a system seem broken when it just can't breathe. Check the breaker panel for a tripped breaker, and if you have a gas furnace, make sure the gas valve is open. If the outdoor unit or an indoor switch has a power cutoff nearby, make sure it hasn't been bumped off. If everything checks out and the system still isn't working, a licensed contractor can diagnose the rest.
