Pilot Assembly Replacement in Round Rock, TX

That's the signature of a weak thermocouple. It lights, but it no longer makes enough millivolt to hold the gas valve's safety magnet open, so the valve closes the second you stop overriding it by holding the knob. We meter the output (a healthy one reads around 25-30 mV open-circuit) and replace the failed proving part on your existing ignition — it's the most common fix for exactly this symptom.

This replaces a worn part on the ignition system you already have; pilot light installation builds a new system where none works. You're not redesigning how the fireplace lights — you're swapping the thermocouple, thermopile, igniter, or pilot hood that aged out of the existing setup. If there's a working architecture and one dead part, this is the right service.

Because the dropout is usually the cheap proving part, not the valve. A dropping pilot can mean a weak thermocouple (this fix) or, less often, a valve magnet that won't hold even on a healthy millivolt signal (valve work). We meter the thermocouple output and check the valve's hold so we replace the right thing — and confirm it isn't really a clogged orifice or a draft first.

A fresh thermocouple won't fix a clogged pilot orifice, a draft pulling the flame off the sensor tip, low gas pressure, or a failing valve magnet. That's why we re-read the millivolt after the swap and aim the flame to fully envelop the sensor, and replace the full hood-and-thermocouple assembly when the hood and orifice are also worn rather than just the one part.

Age doesn't exempt a flue; use pattern does. A twelve-year-old prefab that's burned every winter has accumulated creosote and, after ten idle months a year, debris and possible nests. The annual sweep verifies it's clear and the written report documents the firebox, liner, and cap condition. On a newer system the value is early-catch maintenance that keeps a good system out of the expensive-repair column.

Yes, and it's most of what we do in Round Rock. Factory-built (prefab) systems need a specific touch: poly brush heads on stainless liners, attention to the air-cooled chimney sections and firestops, and the manufacturer's clearance specs. We service all three fuel types — wood, gas, pellet — to the same documented standard.

Method selection, full-path cleaning, HEPA capture, and a photographed written report. The cheap special brushes the easy reach and leaves. We assess creosote stage, choose the correct head for your liner type, capture every particle so your home stays clean, and hand you documentation you can keep on file. You're paying for a verified-safe, recorded system.
