Shelby County runs its systems almost year round
Your furnace works October through April here, and the heat still has to fight nights that average 26°F. That's seven months of the burner cycling on and off, and every start puts wear on the igniter and the parts that light it. When one gives out, the house goes cold on the coldest nights, not the mild ones.
Then the air conditioner takes over for May through September, running against afternoons near 85°F. Almost half the homes here heat with electricity, so when a winter storm knocks out power, the furnace stops with it. Shelby County has seen 11 winter storms and 50 damaging wind events over the past ten years, and across Kentucky nearly a quarter of households lost power for a full day or more in 2024. A system that was already struggling is the one least likely to come back on its own once the power does.

Kentucky requires HVAC contractors to hold a state license.
Kentucky's Department of Housing, Buildings and Construction issues that license, and it covers the contractor, not the individual job. The state has this contractor on record before they take on work like yours.
For a heating and cooling repair, that license is what stands behind the person in your home. It applies to the contractor as a whole, not to this one visit, so the same license covers whatever else they're licensed to do in your house. Kentucky is the one checking who is allowed to do this work in the first place.

- Why is my heat not working?
- A few things cause this, and where you start depends on what you have. If the thermostat screen is blank or won't hold a setting, check the batteries first. If you hear the system try to start and then shut off, that's often the igniter or a safety switch cutting power before the burner lights. Nearly half the homes in Shelbyville heat with electricity, and on those systems a tripped breaker or a bad heating element can look like the same 'no heat' problem from the thermostat. With lows averaging 26°F here in the dead of winter, a system that's stalling rather than fully failing needs a look soon, before a cold snap turns it into no heat at all.
- Why is my system running but not cooling the house?
- If air is moving but it isn't cold, the first thing to check is the filter. A filter clogged with dust chokes off airflow across the coil, and the coil can ice over as a result, which makes cooling worse the longer it runs. If the filter is clean and the air still isn't cold, the problem is more likely low refrigerant from a leak or a failing compressor, and that needs a contractor to diagnose. Afternoons here reach 85°F for five months of the year, so a system that's cooling poorly now usually keeps losing ground, not gaining it back on its own.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Confirm it's set to heat or cool as needed and the batteries are good if it uses them. Next, check the filter and replace it if it's visibly dirty, since a blocked filter can cause problems that look like bigger failures. Check your breaker panel for a tripped breaker, especially after a storm. Kentucky sees its share of winter storms and damaging wind, and nearly a quarter of households in the state lost power for at least 24 hours in 2024, so a breaker or a reset button is worth ruling out before assuming the system itself has failed. If those don't explain it, the issue is inside the system and a licensed contractor will need to diagnose it directly.
