Eleven months of work a year in Lincoln County
Your system in Brookhaven barely gets a rest. Heat runs November through March, and winter nights average 39°F, so the furnace or heat pump cycles on and off most nights. Cooling picks up in May and runs through October, with afternoons averaging 91°F. That is eleven months where something in your system is working to keep the house comfortable.
Most homes here heat with electricity, so a heat pump or electric furnace is doing double duty across both seasons, and the parts that start it up wear from constant cycling. Lincoln County has also seen 79 damaging wind events and 3 winter storms over the past ten years, and statewide, 3 in 10 households lost power for at least a day in 2024. When the power drops and comes back, most systems restart on their own, but a storm can still trip a breaker or leave a unit needing a reset before it runs again.

Mississippi requires HVAC contractors to hold a state license.
The license belongs to the contractor, not to the specific repair. Mississippi's State Board of Contractors tested that contractor and keeps them on record, separate from any particular job they take on.
For a repair like this, that license is what stands behind the person working on your system. The board tested them before they were allowed to take this kind of job, and the license is what you can point to afterward if the work was not done right.

- Why is my heat not working?
- Start with the thermostat. If it's set to heat and the temperature is above room temperature but nothing happens, check the breaker next. A tripped breaker or a reset switch on the unit itself will stop it cold. If power looks fine and you still get no heat, the igniter or flame sensor may have failed on a gas furnace, or the reversing valve may be the problem on a heat pump. That's a job for a licensed contractor to diagnose, since guessing past this point risks more damage.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and a coil that can't move enough air will ice over and stop cooling the house even though the system keeps running. If the filter is clean, look at the outdoor unit. Leaves, grass clippings or a fence too close can block the outdoor coil the same way. If both look fine and the air coming from the vents is warm, the system may be low on refrigerant from a leak, and that repair needs a licensed contractor with gauges and the right tools.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings first. A thermostat set to the wrong mode or with dead batteries can look exactly like a dead system. Next, check the breaker panel for a tripped breaker, since summer afternoons here average 91°F and push a system hard enough to trip one. Look at the air filter and replace it if it's gray or clogged. If the outdoor unit is covered in leaves or debris, clear it. If the system still isn't working after that, a licensed contractor will need to look at it, and Mississippi requires HVAC contractors to hold a state license to do that work.
