Why won't my gas fireplace light when it's very cold outside?
In Black Mountain the failure almost always shows up on an inversion morning — cold air pools in the Swannanoa Valley and runs 10 to 15 degrees below Asheville, so your fireplace faces its hardest test right at dawn. The town is on natural gas, so the usual suspects are a fading ignition part or a cold, downdrafting flue rather than the fuel itself.
The valley inversion morning
On clear winter nights, cold dense air sinks and settles on the Swannanoa Valley floor, which is why Black Mountain mornings can be brutally colder than the ridgelines above. That pooled cold is exactly when a marginal thermocouple drops below the millivolts it needs, or when a stone-cold flue is most plugged with heavy air. If your fireplace balks at daybreak and lights fine by afternoon, that temperature swing is the tell.
Wooded lots make downdraft worse
Montreat and the shaded lots around Ridgecrest stay cool, damp, and ringed by tall trees, and those trees plus the valley walls stir up downdrafts that push against a chimney's draft. An open-hearth gas log feels this most; a sealed direct-vent unit is largely immune to it. Sorting a draft problem from a worn sensor is quick for our techs, and it's licensed gas work either way. Late frost dates here mean you'll want the fireplace reliable well into spring.
