Ten months of work a year, in Lee County heat and cold
Your system in Lee County only gets a couple months off. Heat runs November through March, and the AC picks up again by May and carries through September. That is ten months of the year with something always cycling on.
Summer afternoons here push into the 90s, so the compressor runs hard for hours at a stretch, day after day. Winter nights average 34°F, cold enough that the furnace or heat pump has to cycle on often just to hold the house steady. Lee County has also logged 94 damaging wind events over the last ten years, and an outdoor unit left exposed to that kind of wind can end up knocked out of alignment or caked in debris. More than half the homes here heat with electricity, so when a storm knocks the power out, as it did for 30% of Mississippi households at some point in 2024, there is no backup burner to fall back on until it comes back.

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, so the same license that qualifies someone to install a system is what qualifies them to repair yours.
For a repair like this, that license is what stands behind the work. The board is the record of who holds it, and that record covers the contractor doing the job, not a separate approval for this repair.

- Why is my heat not working?
- Most of the time it comes down to power, gas, or airflow. Check that the thermostat is set to heat and the temperature is above room temperature, and check the breaker if the display is blank. If you smell gas or the furnace clicks but will not light, that points to the igniter or a safety switch, and it needs a contractor to look at it. Over half the homes here heat with electricity, so if your heat pump is running but blowing cool air on a cold night, that can just mean it is working harder than usual, not that it is broken.
- Why is my system running but not cooling the house?
- If the system runs but the air is not cold, the most common causes are a dirty filter, a frozen coil, or low refrigerant. A clogged filter starves the system of airflow, and if that goes on long enough the coil can freeze over and stop cooling altogether. On a 90 degree afternoon a struggling system falls behind fast, so if the filter looks clean and the vents are open, it is time to call a contractor before it stops cooling entirely.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to the right mode, the temperature is set past the room temperature, and the batteries are not dead. Next check the breaker box for a tripped breaker, and check that the filter is not clogged, since a blocked filter can shut a system down on its own. If the outdoor unit is covered in debris after a storm, clear it, since wind events are common here and can block airflow. If those checks do not fix it, a licensed contractor will need to diagnose it, and only a Mississippi-licensed contractor can legally do the repair.
