Eight months of heat, and a grid that doesn't always hold
Bluefield needs a working furnace from October through May. On winter nights averaging 25°F, the burner is cycling on and off for hours at a stretch, and every start puts wear on the igniter and the flame sensor. Over enough winters, one of them stops responding, and the furnace either won't light or shuts down mid-cycle.
Mercer County has seen 23 winter storms and 47 damaging wind events over the last ten years, and more than a third of West Virginia households lost power for a full day or longer in 2024. A furnace that loses power shuts down no matter what is wrong with it, and when the power comes back, some furnaces need a hand to get going again.

West Virginia requires HVAC contractors to hold a state license.
West Virginia licenses HVAC contractors through the Commissioner of Labor. That license belongs to the contractor, not to any single job, so the person who shows up at your door is the one the state tested and keeps on record, not something issued for your furnace alone.
For a furnace repair, that license is what stands behind the work. Gas connections are the part that matters most, since a loose fitting or a bad seal is what makes the job dangerous, and in this state it is the contractor's license that says they have been checked before being trusted with that.

- 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 above room temperature and has fresh batteries if it takes them. Next check the furnace switch, which looks like a light switch near the unit, and the breaker at your panel. If those are fine, the igniter or a safety switch inside the furnace may have failed, and that calls for a contractor to open it up and test it.
- Why is my furnace blowing cold air?
- A furnace blows cold air for a few seconds when it first starts, while it warms up before the blower kicks in fully. If cold air keeps coming, the igniter may not be lighting the burners, so the blower runs but nothing heats the air passing through it. A clogged filter can also starve the burners of the airflow they need to stay lit. Either way, a furnace blowing only cold air needs a contractor to check the burners and the ignition system.
- Why won't my furnace pilot light stay lit?
- This usually means the thermocouple has worn out and can no longer sense that the pilot is burning. Once it can't sense the flame, it shuts the gas valve as a safety measure. A draft blowing across the pilot can also snuff it out, especially in older furnaces with looser cabinets. If you relight it and it goes out again within a minute or two, the thermocouple is the likely cause and a contractor can replace it. Don't keep relighting it repeatedly if it won't hold. That's a sign the part needs attention, not another match.
