Gas Fireplace Repair Services in Dallas

Gas fireplaces are everywhere in Dallas, from townhomes in Uptown to newer houses in Plano and Richardson. They are easy to use, until the day the pilot will not light or the flame looks wrong. Most problems come from a few small parts that wear out over time.

We test the whole system: the pilot, the safety sensors, the igniter, the valve, the controls and the vent. Then we tell you what failed and what it costs to fix, before we replace anything.

Small, weak or yellow flame Dirty burner, logs out of place Clean burner, set the logs right
Pilot will not light at all Gas valve off, clogged pilot tube Check the valve, clean the pilot

Quick Checks Before You Call

You can try these safely before booking a gas fireplace repair:

  1. Make sure the gas valve near the fireplace is open (handle in line with the pipe).
  2. Replace the batteries in the remote, the receiver and the igniter.
  3. Check that the wall switch is on and the breaker has not tripped.
  4. Follow the lighting steps on the label inside the lower panel, exactly as written.
  5. If it still will not light, turn the valve off and call us. Do not keep trying to light it.

Gas Fireplace Parts We Repair

Most gas fireplace repairs come down to one of the parts below. We test before we replace, so you only pay for the part that failed.

Pilot Light, Thermocouple and Thermopile Repair

The pilot is the small flame that lights the main burner. Next to it sits a thermocouple, a safety sensor that tells the gas valve the pilot is lit. If the thermocouple gets dirty or wears out, the valve shuts the gas off and the pilot goes out.

Many gas fireplaces also have a thermopile. It turns pilot heat into a small electric charge that opens the valve when you flip the switch. A weak thermopile is a top reason a fireplace will not turn on even though the pilot is burning. We clean the pilot assembly, test both parts with a meter, and replace them when they read low.

Igniter and Electronic Ignition Repair

Newer gas fireplaces use an electronic igniter or a control module instead of a standing pilot. When the igniter clicks but nothing lights, the spark gap may be off or the pilot tube clogged. When nothing clicks at all, the battery, module or wiring is often the problem. We test each one and replace only what failed.

Gas Starter and Key Valve Repair

Many older Dallas wood fireplaces have a gas starter, a pipe under the grate that lights the wood. It is turned on with a key valve in the floor or wall. Over time the holes in the starter pipe clog with ash and the key valve gets stiff or leaks. We clean or replace the starter pipe and replace worn key valves at the fireplace. Repairs to the gas supply line feeding it are done by a licensed plumber.

Soot on the Glass and Flame Problems

A healthy gas flame is steady and mostly even across the logs. Black soot on the glass, a tall smoky flame or a flame that lifts off the burner means the fuel is not burning cleanly. Common causes are logs set in the wrong spots, burner ports clogged with dust or spider webs, a dirty air shutter or a vent that is not drawing. We clean the burner and pilot, reset the logs to the maker’s diagram and check the vent. Then we clean the glass with a product made for fireplace glass.

Gas Log Installation

Logs that are crumbling, faded or set in the wrong spots can block the flame and cause soot. We reset logs to the maker’s pattern, refurbish worn sets and install new ones. See our gas log installation page for vented and vent-free options.

Gas Fireplace Smells and Carbon Monoxide Safety

A new gas fireplace can smell like hot paint for the first few hours of use. That fades. A rotten-egg smell is different. That is the odor added to natural gas, so leave the house and call Atmos Energy or 911.

A blocked or cracked vent can push carbon monoxide into the room without any smell. The EPA lists leaking chimneys and fireplaces among the indoor sources of carbon monoxide, and notes the CPSC advice: CO alarms on every level and a yearly professional inspection of fuel-burning appliances. We check the vent, the flue and the cap on every gas fireplace repair. A yearly fireplace inspection or chimney sweep also catches nests and blockages.

Signs Your Gas Fireplace Needs Repair

  • The pilot will not light or will not stay lit
  • The burner lights with a loud pop or a delay
  • Black soot on the glass, logs or the front of the unit
  • A yellow, lazy or uneven flame
  • The fireplace shuts off on its own after a few minutes
  • A gas smell, or your CO alarm goes off

Questions

Gas Fireplace Repair FAQs

Why won't my gas fireplace light when I flip the switch?

If the pilot is lit but the burner will not come on, the thermopile is often weak, or the wall switch, wiring or remote has failed. If the pilot is out, the fireplace will not light at all. Check the remote batteries and the gas valve first, then call us.

Why does my gas fireplace pilot keep going out?

The most common cause is a worn or dirty thermocouple, which shuts off the gas when it cannot sense the pilot flame. A dirty pilot tube, a draft from the vent or low gas pressure can also do it.

What is the most common problem with a gas fireplace?

Pilot and ignition problems are the most common, usually from a dirty pilot, a worn thermocouple or thermopile, or a bad igniter. Dead batteries in the remote or receiver come next.

How much does gas fireplace repair cost in Dallas?

It depends on the part. Cleaning a pilot or replacing a thermocouple costs much less than a new valve or control module. We find the cause first and give you a free written estimate before any part is replaced.

Can a plumber fix a gas fireplace?

A plumber runs and repairs the gas line to the fireplace. The parts inside the fireplace, like the pilot, valve, burner, logs and vent, are hearth work. We repair the fireplace and work with a licensed plumber when the supply line is the problem.

Why is there black soot on my gas fireplace glass?

Soot usually means the logs are out of place, the burner ports or air shutter are dirty, or the vent is not drawing well. Soot is a sign of poor combustion, so have it checked rather than just wiping it off.

What should I do if I smell gas?

Do not touch the fireplace or any light switch. Leave the house, then call Atmos Energy or 911 from outside. Call us after the gas company says it is safe.

What is the average lifespan of a gas fireplace?

It depends on the model, how often you use it and how well it is serviced. The firebox and burner usually last much longer than the small parts. Thermocouples, igniters and batteries wear out sooner and are replaced along the way.

How often should a gas fireplace be serviced?

Once a year, before the cool season. NFPA 211 calls for a yearly inspection of chimneys and vents, and most gas fireplace makers recommend yearly service.
