Twelve months of work, most of it in rough conditions

Holly Springs asks for heat from October through April and cooling from May through September. That covers all twelve months, with no stretch where the system just sits idle. On winter nights averaging 33°F, the furnace cycles on and off for hours, and each start is a strain on the igniter. Summer afternoons near 90°F push the air conditioner to run long stretches to keep up, which wears on the compressor and the run capacitor that gets it started.

Marshall County has seen 11 winter storms and 29 damaging wind events over the past ten years, and across Mississippi, 30% of households went at least 24 hours without power in 2024. When the power drops and comes back, a furnace or air conditioner that was mid-cycle can trip a breaker or fail to restart. With 43.5% of homes here heating with electricity, a power outage during those winter months means the heat goes with it.

Mississippi requires HVAC contractors to hold a state license.

The State Board of Contractors is who licenses HVAC contractors in Mississippi. That license belongs to the contractor, not to any one job, so the same license covers this repair and the next one.

For a repair on your heating and cooling system, that state license is what stands behind the person doing the work. If gas is part of the repair, a sound connection is the part that matters most, since a leak there is what turns a repair into a hazard.

Why is my heat not working?
Start with the thermostat. Make sure it is set to heat and set a few degrees above the room temperature, and check that it has power if it runs on batteries. If the thermostat looks right, check the breaker for the furnace or air handler, since a tripped breaker will shut the whole system down. Gas furnaces will not run if the pilot or igniter fails, or if the gas supply is off. With winter nights here averaging 33°F, a furnace that will not start needs a contractor to look at the ignition system and safety controls before you lose more heat.
Why is my system running but not cooling the house?
The most common cause is a dirty air filter blocking airflow across the coil. Check the filter first and replace it if it looks gray or clogged. If the filter is clean and the air coming from the vents is warm, the system may be low on refrigerant or the outdoor unit's coil may be blocked with dirt or leaves. A contractor will need to check refrigerant charge and the coils, since running a low system for long can damage the compressor.
What can I check before calling for HVAC repair?
Check the thermostat settings and batteries first, since a wrong setting or dead batteries can look like a bigger problem. Check the breaker panel for a tripped breaker on the furnace or air handler circuit. Check the air filter and replace it if it is dirty, since a blocked filter causes both heating and cooling problems. If the outdoor unit is covered in leaves or debris, clearing the area around it can help. If none of that fixes it, a licensed contractor can diagnose what is actually wrong.
