Clark County runs its system nearly all year
Your furnace works October through April here, and your air conditioner takes over for the five months after that. There is almost no season where the system gets to sit idle. Winter nights average 26°F, cold enough that the burner cycles on and off for hours to hold the house steady, and each start puts wear on the igniter. Summer afternoons average 86°F, and the compressor runs long stretches to keep up.
Clark County also sees real storms. Nine winter storms and 79 damaging wind events have hit the area over the past ten years, and statewide, 17% of Indiana households lost power for at least 24 hours in 2024. A hard freeze or a wind event that cuts power partway through the season is often what pushes a strained system past the point it can recover on its own.

A new furnace and air conditioner would cut about $110 a year off heating and cooling for a typical Clark County home.
Estimates for a typical Clark County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Indiana fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
In Indiana, HVAC licensing for homes is left to the counties and cities.

- 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, and check any switch that looks like a light switch near the furnace itself, since that shuts off power too. If those are fine, look at the flame through the furnace's viewing window if it has one. No flame usually means the igniter has failed or the flame sensor is dirty and shutting the burner off. A furnace that blows cold air but never lights needs a contractor, since at that point it's electrical or gas, not something to keep testing on your own.
- 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 the coil can ice over, which makes the air coming out feel warm even though the system is running. Check the outdoor unit too. If the fan isn't spinning or you don't feel warm air blowing off the coil, the unit is trying to cool but can't move the heat outside. Turn the system off and let any ice melt before a contractor looks at it, since running it iced up can damage the compressor.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it has any, and the breaker for the system. Check the air filter next and replace it if you can't see light through it. If it's the furnace, look for a reset button on the unit itself, usually red, and check that the switch near the furnace is on. If it's the air conditioner, check that the outdoor unit isn't blocked by leaves or grass clippings. If none of that changes anything, a contractor will need to look at what's inside the unit.
