Martinsville runs its heat and its air almost all year
Eight months of heat, four months of cooling, and only a short break in between. That kind of run time adds up on a furnace, especially on nights that drop to 23°F, when the burner is cycling on and off for hours to keep up. Each cycle is wear on the igniter, and when it finally gives out, the furnace won't light at all.
Summer afternoons near 83°F put the same kind of load on the air conditioner, and a low refrigerant charge or a failing capacitor shows up fast when the unit is running that hard. Morgan County also sees its share of wind and winter storms, and either one can knock out power. Most systems come back on their own once power returns, but a storm that bends a fan blade or trips a breaker can leave damage behind after the lights come back on.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Indiana has no state license for HVAC contractors. That rule is left to counties and cities, so whether the person working on your system needs a local license depends on where in Morgan County the house sits, not on anything the state checked.
Because there is no state license behind this repair, Indiana keeps no record of who is qualified to work on a heating and cooling system. Whatever protection exists here comes from what Morgan County itself requires, since the state leaves that decision to the county.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace before you assume the worst. Check that the thermostat is set to heat and a few degrees above room temperature, and check the breaker and the furnace switch, which looks like a regular light switch near the unit. If the furnace has a standing pilot, see whether it is lit. A furnace that runs but blows cold air often has an ignition problem, and one that will not start at all may be tripping a safety switch. With winter nights here averaging 23°F, a furnace that is down for long is worth getting to fast.
- 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 stop cooling the air even though the blower keeps running. Check the outdoor unit too, and clear away anything blocking it, leaves, grass clippings, a fence too close to the sides. If the filter is clean and the outdoor unit is clear and you are still getting warm air, the system may be low on refrigerant, and that calls for a contractor with gauges to check it.
- 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 before anything else. Check the air filter and replace it if it is gray or matted, since a blocked filter causes both heating and cooling problems. Look at the outdoor unit for anything blocking it and the indoor vents for anything closed off. If the furnace has a standing pilot, check whether it is out. Past that, a contractor will need to look at the parts inside the cabinet, and they will price the job once they see what it needs.
