Twelve months of work, with storms that cut the power
Your system runs almost year round in Mount Washington, heat from October through April, cooling from May through September. Winter nights average 28°F from December through February, so the furnace cycles on and off for hours at a stretch, and each start puts wear on the igniter. Summer afternoons average 86°F, and the compressor runs long stretches to keep the house cool.
Nearly half the homes here heat with electricity, so a power outage takes the heat with it. Bullitt County has logged 14 winter storms and 58 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 and comes back later, the system has to start cold, and that is when a weak part finally gives out.

Kentucky requires HVAC contractors to hold a state license.
The license comes from the Department of Housing, Buildings and Construction. It's issued to the contractor, not to each job, so it covers the business you hire rather than the specific repair on your system.
For a repair like this, the license is what stands behind the person doing the work. Kentucky put them through the process to be licensed and keeps them on record. There's no separate state check on your furnace or your coil before or after the work, the license is what's standing between you and the job.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace. If the thermostat screen is blank, check the breaker before you assume the furnace itself has failed. Gas furnaces also need a pilot light or an igniter to catch, so a furnace that runs the blower but never gets warm often has a problem there. With winter nights here averaging 28°F, a furnace that is short cycling or blowing cold air needs a contractor's attention soon rather than after a few more cold nights.
- Why is my system running but not cooling the house?
- The system is moving air, but something is stopping it from cooling that air. A dirty filter or a frozen coil can both do this, and a frozen coil often traces back to that same dirty filter or low refrigerant. Check the filter first since that is the one thing you can look at yourself. If the filter is clean and the air still is not cold, the problem is inside the system and a contractor needs to look at it.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and its batteries, then check the breaker for the system. Check the filter next, since a clogged filter can block airflow enough to stop a furnace or air conditioner from working right. For a gas furnace, look for a pilot light if it has one. If everything there looks normal and the system still is not heating or cooling the house, that points to something inside the system, and a licensed contractor can diagnose it from there.
