Eleven months of work, most years
Vicksburg only gets a real break from its HVAC system for about a month a year. Heat runs November through March, and the system switches over to cooling for May through October, with summer afternoons averaging 91°F. That is a lot of hours on the compressor and the blower motor, and not much time for either side of the system to sit idle.
Most homes here heat with electricity, so a lot rides on that system staying powered. Warren County has seen 145 damaging wind events over the past ten years, and in 2024, 30% of Mississippi households lost power for at least a day. A storm that knocks out power for a day can leave a house with no heat on a cold night or no cooling on a 91°F afternoon, and when the power comes back, not everything always comes back on its own.

Mississippi requires HVAC contractors to hold a state license.
Mississippi licenses HVAC contractors through the State Board of Contractors. The license belongs to the contractor, not to the job in front of them, so the same license that lets them install a system is what covers them coming out to repair yours.
That license is what stands behind the person working on your system. A repair to a heating and cooling system falls under it, whether the job is a simple fix or something more involved, because in Mississippi the license covers the contractor across the work they do, not one job at a time.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat, the temperature is set above the room temperature, and the display is lit. If the thermostat looks fine, check the breaker for the furnace or air handler, since a tripped breaker will stop the system cold. Gas furnaces also need the pilot or igniter to work, so if you smell gas at any point, leave the house and call the gas company before anyone touches the system. With winter nights here averaging 39°F, a furnace that will not start is not something to wait out overnight.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust chokes off airflow, and a system starved for air cannot pull enough heat out of the house to cool it. Next look at the outdoor unit. If the coil is covered in leaves, grass clippings, or ice, the system cannot dump heat outside no matter how hard it runs. If the filter is clean and the outdoor unit is clear but the house still will not cool down, especially with afternoons here running near 91°F, the system likely needs a contractor to check refrigerant levels and the components a homeowner cannot safely inspect.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it uses them, and the breaker for the system. Check the air filter and replace it if it is gray or clogged, since that alone fixes a surprising number of airflow complaints. Look at the outdoor unit for debris, leaves, or ice blocking it. If the system still is not heating or cooling right after that, a licensed contractor will need to diagnose it, since Mississippi requires HVAC contractors to hold a state license for this kind of repair work.
