Trusted Gas Fireplace Repair for San Antonio Homeowners
A gas fireplace that won’t light, fires up and then shuts off, or smells like gas when it runs is not something to ignore. We’re Hadley Chimney San Antonio, and we’ve been repairing gas fireplaces across San Antonio since 2003. That’s more than two decades of diagnosing failed thermopiles, clogged burner ports, faulty gas valves, and cracked refractory panels in homes from Alamo Heights to Leon Valley. When you call (254) 276-4116, a live person answers. We book the visit, give you a written price before any work starts, and show up in a tracked window with photo documentation of everything we find.
Every gas fireplace repair we do is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right, including a free second visit if the repair fails. That’s a written guarantee, not a handshake.
What Our Gas Fireplace Repair Service Includes
Gas fireplaces are simpler than wood-burning systems in some ways, but they’re more complicated in others. You’ve got gas lines, ignition systems, thermocouples, thermopiles, valve assemblies, and a sealed combustion chamber. When any one of those components acts up, the whole unit stops working or becomes unsafe. Here’s what we handle in San Antonio.
Gas Valve and Control System Repair
The gas valve is the heart of your fireplace. It regulates fuel flow from your home’s gas line into the burner. When a valve fails, you might get no flame at all, a weak flame, or a unit that lights but won’t stay lit because the valve isn’t holding pressure. We test gas pressure with a manometer, inspect the valve body for wear or corrosion, and replace faulty valves with OEM parts from suppliers like Famco and Copperfield. If the issue is electrical rather than mechanical, we trace the circuit from the wall switch or remote receiver to the valve and fix what’s actually broken.
Thermocouple and Thermopile Replacement
The thermocouple and thermopile are small safety sensors that sit in the pilot flame. They generate the tiny electrical current that tells the gas valve “it’s safe to keep the gas on.” If one of these fails, your fireplace shuts down as a safety precaution. We see this constantly in San Antonio homes, especially in older units that have run thousands of cycles. We test the millivolt output of these sensors, and when they’re weak, we replace them with new components and verify the pilot assembly is positioned correctly for reliable ignition.
Pilot Assembly and Ignition System Repair
Standing pilots should produce a steady blue flame. Intermittent pilot ignition (IPI) systems should fire on demand from the wall switch or remote. When the flame sputters, the pilot won’t stay lit, or the igniter clicks without firing, something in the ignition chain is failing. We clean pilot orifices (the tiny hole the gas comes through), clear spider nests and debris that block the pilot tube, and replace igniter modules or spark electrodes as needed. San Antonio’s mild winters mean lots of spiders and insects taking up residence in pilot tubes during the off season, so this is one of our most common repairs every fall - and a frequent reason homeowners in the area call us for Gas Fireplace Repair in Floresville and surrounding communities.
Burner Repair and Replacement
The burner is the tube or pan assembly where gas and air mix to create the flame. Over time, burner ports clog with soot, rust, or debris, producing a lazy yellow flame instead of a crisp blue-with-yellow-tips flame. That’s both a performance issue and a warning sign of incomplete combustion. We remove the burner assembly, clean each port mechanically, and inspect for cracks or warping. If the burner is beyond saving, we source a direct replacement and install it with fresh gaskets to maintain a proper seal.
Log Set and Refractory Panel Replacement
The ceramic logs and refractory panels inside a gas fireplace are cosmetic in one sense, but they also shape the flame pattern and protect the firebox. Cracked panels allow heat to reach the metal firebox shell, which can cause premature failure. We replace damaged refractory panels, reposition logs so they don’t obstruct the flame, and use manufacturer-specified log sets so the unit looks and performs as designed. If you’ve got a vented or vent-free unit with a cracked set, we’ll match it.
Remote Control and Wall Switch Repair
Modern gas fireplaces rely on remote controls, wall switches, or smart home integration. When the remote stops syncing, the switch stops responding, or the receiver fails, the fireplace won’t turn on even though the gas components are fine. We diagnose control module failures, replace receiver boards, resync remotes, and install new control kits when the original system has been discontinued. This is a repair that often gets misdiagnosed as a gas problem, and it’s one we solve quickly.
Gas Leak Detection and Line Inspection
If you smell gas near your fireplace, call us immediately. Natural gas is odorized with mercaptan so you can detect it, and any gas odor means a potential leak. We use electronic gas detectors and soap-solution testing to locate the source, whether it’s a loose flare fitting, a cracked flex line, or a failing valve diaphragm. We won’t leave a unit running until we’ve verified there are no leaks upstream or downstream of the valve. Gas plumbing is not a DIY repair, and a leak is the one situation where you should shut off the gas at the appliance shutoff valve and call a pro before doing anything else.

Styles & brands we work with
Brands We Service for Gas Fireplace Repair
We work on gas fireplaces from every major manufacturer, and we’ve seen enough units in San Antonio to know which brands hold up and which ones develop predictable problems. We stock components from Copperfield, a brand that supplies gas logs, burners, and accessories to the hearth industry. When a Copperfield log set cracks or a burner needs replacing, we can usually get the part on the truck and finish the job in one visit.
For venting and flexible connector needs, we carry DuraFlex and Famco products. DuraFlex is the standard for aluminum and stainless steel chimney liners and gas venting, and Famco makes high-quality gas connectors and termination caps that hold up in South Texas humidity. We’ve also used HeatShield in gas fireplace applications where firebox repair is needed. Whether you have a Heat & Glo, Majestic, Monessen, Napoleon, or any other make, we service it and source the right parts for the job.
Signs You Need Gas Fireplace Repair Right Now
- Gas odor when the fireplace runs or sits idle. Any smell of gas around your fireplace is a problem. It could be a loose connection, a failing valve, or a cracked flex line. Shut the gas off at the appliance shutoff valve and call us. We’ll find the leak before anyone turns it back on.
- The pilot light won’t stay lit. A pilot that lights and then goes out usually means a weak thermocouple or a clogged pilot orifice. It’s a safety system doing its job, but the underlying issue still needs repair. In San Antonio, spider activity in pilot tubes is a very common culprit during warmer months.
- Soot buildup on the glass or logs. Black soot on the inside of the glass means incomplete combustion. The air-to-gas ratio is off, likely from clogged burner ports or a blocked air shutter. Left alone, soot buildup can clog the burner further and produce carbon monoxide.
- The flame is mostly yellow or orange. A healthy gas flame is blue at the base with yellow tips. A mostly yellow flame indicates incomplete combustion. We check the burner and venting to correct it. This is a combustion efficiency issue, not just an aesthetic one.
- Clicking sound with no ignition. You hear the igniter clicking but the burner never catches. That’s usually a failed spark electrode, a dead igniter module, or a pilot that won’t light. We test each component in sequence and replace only what’s actually failed.
Our Gas Fireplace Repair Process – Step by Step
- 1
You call, a person answers. Call (254) 276-4116 and you’ll talk to a live human, not a voicemail tree. We ask what the fireplace is doing (or not doing), confirm your address in San Antonio or a nearby community, and book a time that works. You get a tracked arrival window, not a four-hour guess.
- 2
We arrive on time and diagnose the issue. Our background-checked, uniformed technician shows up in the window we gave you. We run through the unit’s ignition sequence, test gas pressure, check millivolt readings from the thermocouple and thermopile, and inspect the burner, valve, venting, and electrical controls.
- 3
You get a written price before any work starts. After diagnosis, we show you what we found and what it costs to fix. No surprise charges, no pressure. You approve the repair before we pick up a tool. This is a standing commitment from Hadley Chimney San Antonio, backed by The Relay Visibility Guarantee.
- 4
We complete the repair with the right parts. We use components from manufacturers like Famco, Copperfield, and DuraFlex rather than whatever is cheapest on the truck. Every repair is tested after installation: we verify ignition, check for gas leaks at every connection we touched, and confirm proper flame appearance.
- 5
You see the work before we leave. We photograph the failed component, the new part, and the finished result. You get those photos in a digital report along with your invoice, payable from a link. Every repair includes a written guarantee and a free second visit if it fails within 365 days. That’s our 365-Day Done Right Promise.
