Nicholasville runs its system almost year round
Your furnace works October through April here, and the air conditioner takes over May through September. That is 12 months with barely a break between seasons, and both sides of your system feel it.
Winter nights averaging 27°F mean the burner cycles on and off for hours at a time, and every start puts wear on the igniter. Summer afternoons near 85°F keep the compressor under steady load for five straight months. Most homes here heat with electricity, so when storms knock out power, the furnace stops with it. Jessamine County has seen 13 winter storms and 37 damaging wind events over the past ten years, and across Kentucky almost a quarter of households lost power for a full day or more in 2024. When the power drops on a cold night, you find out fast whether your system comes back on its own.

Kentucky requires HVAC contractors to hold a state license.
Kentucky's Department of Housing, Buildings and Construction issues that license, and it tests the contractor before handing it out. What you get is a record on file with the state, tied to the person or company, not to any single job. It tells you the contractor met the state's standard to do this work in the first place.
That license is what stands behind the repair on your system, since Kentucky is the one setting and checking the standard here. The license covers the contractor generally, not this particular repair, so it says who is qualified to do the work rather than certifying the work itself once it's done.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and the temperature is set above room temperature, not just at it. 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 also stop running if the pilot or igniter fails, or if the flame sensor is dirty and cuts the gas off. Winter nights here get down to 27°F on average, so a furnace that will not fire is not something to leave for later. If the power or breaker is fine and it still will not heat, a contractor needs to look at the igniter, the gas valve, or the flame sensor.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the indoor coil, and a system that cannot move enough air cannot cool the house even when it is running. Next check the outdoor unit and clear away any leaves, grass clippings, or anything blocking the coil or the fan. If the filter is clean and the outdoor unit is clear and the house still is not cooling, the refrigerant charge may be low or the compressor may not be working right, and that calls for a contractor. With afternoons here reaching 85°F in summer, a system that runs without cooling usually means it is working harder for less, not that it will fix itself.
- 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 furnace or air conditioner. Check the air filter and replace it if it is dirty, since a clogged filter causes both heating and cooling problems. Look at the outdoor unit if you have one and clear away anything blocking it. If the system uses a condensate drain, check that the drain line is not clogged or backed up, since a clogged line will shut some systems down on its own. If you have checked these and the system still is not working right, a licensed contractor will need to diagnose it further.
