Gas Fireplace Repair in Plano, TX

The single most common cause is a dirty or misaligned pilot/thermocouple. The thermocouple is a safety sensor that must stay heated by the pilot flame to keep the gas valve open; when it's coated in soot or out of position, the valve shuts off as a safety measure and the unit won't fire. Other frequent culprits are a tripped wall switch, a depleted thermopile, or a closed gas shutoff. We diagnose in order of likelihood and most no-light calls are resolved the same day. As a whole-home crew, while we have the unit open we can also flag a sooting fireplace that's feeding particulate into your air-duct system.

Annually. NFPA 211 calls for a yearly inspection of fireplaces and venting, and gas appliances are no exception. Over a season the burner ports clog, the glass develops a haze, the pilot drifts, and venting can collect debris or pests. An annual service keeps combustion clean, confirms the safety shutoffs work, and catches small drift before it becomes a no-heat night in January. Because we also handle chimney and venting work, you get the appliance and its flue checked by one team in one appointment.

It's a sign of incomplete combustion and shouldn't be ignored. Black sooting usually means the air-to-gas mixture is off, the logs have been moved out of their correct positions, or the burner ports are partially blocked — all of which can also raise carbon monoxide output. It's correctable: we clean and re-port the burner, reset the logs to the manufacturer's layout, and verify the flame burns clean and blue-tipped. We'll also confirm your CO detector placement while we're there, because that's the kind of thing a whole-home team should be looking at.

Treat it as urgent. Don't operate any switches or the fireplace, don't light a flame, leave the area, and if the odor is strong, get everyone out and call your gas utility's emergency line from outside first. A faint odor only during startup can be normal; a steady smell is not and points to a loose connection, a failing valve, or a cracked control. Once the area is safe, we'll pressure-test the gas line and components to locate the leak and make it right.

A unit that lights fine but quits after several minutes is the classic signature of a weak thermopile or a marginal thermocouple — the safety sensor heats up, its voltage sags below the threshold the valve needs, and the valve closes. Restricted venting or an overheating limit switch can produce the same behavior. We measure the thermopile output under load to confirm before replacing anything, so the fix actually addresses the cause rather than masking it.

Plano's 1980s-and-90s master-planned neighborhoods were built fast and built similar, which means a problem in one home's system is usually waiting in the next — and that's where having one team for the whole house pays off. Across West Plano and Willow Bend, the bread-and-butter work is air-duct cleaning and attic insulation top-ups on two-story Collin County homes, bundled with the annual fireplace and chimney check. Homeowners book the breadth, not a single fix: ducts, attic, and firebox handled together, one trusted crew. Gas Fireplace Repair is part of keeping that local housing stock safe, efficient, and up to code.
