Eight months of heat puts real wear on a furnace here
From October through May, your furnace is the thing standing between your house and a 27 degree night. That is eight months of the burner lighting, running, and shutting off, night after night. Most homes in Carter County heat with electricity, so when the furnace struggles, there is no backup warming the house while it gets sorted out.
That long a season also means more chances for something to go wrong right when you need heat most. Winter storms are not rare here, with 33 recorded over the past ten years, and power interruptions come with them. When the power drops and comes back, most furnaces restart on their own, but if a part was already worn down, that restart can be the moment it finally gives out.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way it should, or power isn't reaching the furnace. Check that the thermostat is set below room temperature and has working batteries if it takes them. Next check the furnace switch, the one that looks like a light switch near the unit, and the breaker for it in the panel. If those are fine, a safety switch inside the furnace may have tripped, and that calls for a contractor to find out why.
- Why is my furnace blowing cold air?
- If the air is cold and not just cool, the furnace likely hasn't started burning fuel yet even though the fan is running. That happens when the igniter fails, the flame sensor is dirty, or gas isn't reaching the burners. A clogged filter can also starve the system enough that the air feels cold by the time it reaches the vents. Since homes here need heat from October through May, a furnace stuck blowing cold air is worth getting looked at right away.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit usually means the thermocouple has worn out and can no longer hold the gas valve open. It can also mean a draft is reaching the pilot, or the pilot orifice is partly clogged. This is a repair for a contractor, since it means working with the gas valve directly. A standing pilot itself doesn't use electricity, so a power outage isn't the cause here.
