Corinth runs its system almost year round
Heat runs October through April here, then cooling takes over for May through September. That leaves the furnace or heat pump and the air conditioner with almost no season off.
Winter nights averaging 32°F keep a furnace cycling on and off most of the night, and each start puts a load on the igniter or the ignition system. Summer afternoons near 89°F push the air conditioner to run long stretches to keep up, and that steady load is what wears out a capacitor or a contactor over time. Alcorn County has seen 9 winter storms and 29 damaging wind events over the past ten years, and statewide, 30% of households went at least 24 hours without power in 2024. Over half the homes here heat with electricity, so when the power goes out, heat goes with it until it comes back on.

Mississippi requires HVAC contractors to hold a state license.
Mississippi's Board of Contractors tested this contractor before issuing the license, and it keeps a record of who holds one. The license belongs to the contractor, not to the job, so the same license that covers a furnace repair on one street covers a heat pump repair on the next.
For a repair like this one, that license is what stands behind the work. It means the person doing this repair was tested and is on record with the state, not just hired off a truck with a logo on it.

- Why is my heat not working?
- The most common reason is a bad igniter or a flame sensor that has built up a coating and can no longer detect the flame. Both are small parts that fail on their own over time, not signs the whole furnace is done. If the thermostat display is blank or the fan will not even turn on, check the breaker first. A furnace that hums or clicks but never lights needs a contractor to look at the ignition system.
- Why is my system running but not cooling the house?
- If air is coming out of the vents but it is not cold, the system is likely low on refrigerant or the outdoor unit is not running at all. Refrigerant does not get used up, so low refrigerant means there is a leak somewhere that a contractor needs to find and seal. It can also mean the outdoor fan or compressor has failed while the indoor blower keeps moving warm air through the house. A dirty filter can restrict airflow enough to weaken cooling too, and that one you can check yourself.
- What can I check before calling for HVAC repair?
- Check the filter first. A filter clogged with dust chokes off airflow and can make a system struggle to heat or cool the house. Check that the thermostat has power and is set correctly, and check the breaker for the system if nothing is running at all. Past that, a contractor licensed by the State Board of Contractors will need to diagnose the actual problem.
