Eleven months of work a year in Fayette County
Your furnace runs from October through April here, and the air conditioner takes over from June through September. That leaves one month when the system is not carrying the house. Winter nights average 27°F, cold enough that the furnace cycles on and off through the night, and each start puts wear on the igniter. Summer afternoons average 85°F, and a system running that hard all day is what wears out a capacitor or fails at a dirty coil.
57.3% of homes here heat with electricity, so when the power goes, the heat goes with it. Kentucky saw 24% of households lose power for at least 24 hours in 2024, and Fayette County has logged 14 winter storms and 108 damaging wind events over the past ten years. A furnace or air conditioner that sits through outages like that is a system worth having checked.

Kentucky requires HVAC contractors to hold a state license.
The Department of Housing, Buildings and Construction issues that license, and it goes to the contractor, not to each job. The state tested that contractor before granting it and keeps a record of who holds one. It does not get renewed per job, so it tells you the contractor was qualified to do this kind of work, not that this specific repair was checked afterward.
For a heating and cooling repair in Fayette County, that state license is what stands behind the person working on your system. It is the record that the contractor met Kentucky's requirements to do this kind of work in the first place.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that it has power or fresh batteries. If the thermostat looks fine, check the breaker for the furnace or air handler, since a tripped one will shut the whole system down. Gas furnaces will also stop and lock out after a few failed attempts to light, so if you hear it trying and then going quiet, that points to the igniter or flame sensor rather than the thermostat. With winter nights here averaging 27°F, a furnace that will not start is worth getting looked at the same day.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and when that happens the coil can ice over and blow warm air even though the system is running. Check the thermostat setting too, and make sure nothing is blocking the vents or the outdoor unit. If the filter is clean and air is moving but it just is not cold, the system likely needs a contractor to check refrigerant levels and the coil itself.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it, and the breaker for the furnace or air handler. Check the air filter and replace it if it is dark or clogged, since restricted airflow causes both heating and cooling problems. Look at the outdoor unit if you have one and clear away any leaves, grass clippings or debris around it. If the system still is not working after that, a contractor will need to diagnose it further.
