Henderson County runs its system almost year round
Heat runs October through April here, then cooling takes over for May through September. That leaves a furnace or heat pump and an AC only a few weeks off each year before the other has to take over. Winter nights average 28°F, so the heat is cycling on and off most nights from December through February. Summer afternoons averaging 87°F push the AC hard the rest of the warm months. More than half the homes here heat with electricity, which means the same system has to hold up in both seasons.
Henderson County has seen 82 damaging wind events and 10 winter storms over the past ten years, and in Kentucky about a quarter of households lost power for at least a day in 2024. When power drops, an electric furnace or heat pump stops heating until it comes back, and a home can lose ground on a cold night faster than people expect.

Kentucky requires HVAC contractors to hold a state license.
Kentucky's Department of Housing, Buildings and Construction issues that license, and it's tied to the contractor rather than the job. The state tested the person or business behind the work and keeps a record of them, but it doesn't sign off on any single repair.
For a heating and cooling repair like this, that license is what stands behind the work. It means the contractor coming to look at your system was tested by the state and is on record with it, not just registered as a business name.

- Why is my heat not working?
- Start with the thermostat. If the screen is blank, check the breaker, since a tripped one will kill power to the whole system before it ever reaches the furnace. If the thermostat has power but the furnace still won't fire, listen for it trying to start. A furnace that clicks a few times and shuts off usually has an igniter or flame sensor that's failed, and that's a repair, not something to force by resetting the thermostat over and over. If you hear nothing at all, the filter is worth a look too. A filter clogged enough can make some furnaces shut down as a safety measure. With winter nights here averaging 28°F, a furnace that won't hold a fire is not something to leave for later.
- Why is my system running but not cooling the house?
- If air is coming out of the vents but it's not cold, the system is running without actually cooling, and that points to the refrigerant side. A dirty outdoor coil, a fan that's stopped turning on the outdoor unit, or low refrigerant from a leak can all cause this. Check the outdoor unit first. If the fan on top isn't spinning, or the unit is caked in leaves and dirt, that's part of the problem. A frozen indoor coil can also cause weak or warm airflow, and if you see ice on the indoor unit, turn the system off and let it thaw before anyone touches it. With summer afternoons here averaging 87°F, a system that's only half working will fall behind fast, so it's worth having a contractor look at the refrigerant side rather than waiting it out.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first. It sounds obvious, but a thermostat set to the wrong mode or dead batteries accounts for more no-heat and no-cool calls than people expect. Check the breaker panel next, since a tripped breaker will stop the system cold with no other symptoms. Pull the filter and hold it up to a light. If you can't see light through it, replace it, since restricted airflow can cause a furnace to overheat and shut off or an air conditioner to freeze up. Last, walk around the outdoor unit and clear away any leaves, grass clippings, or debris blocking it. If the system still isn't working after that, a licensed contractor can diagnose what's actually wrong and price the repair for your house.
