The First Cold Night Is When Arlington Gas Fireplaces Quit
It is the same story every November in Arlington. The first front blows through, the house drops to 62 degrees, you flip the wall switch and the gas fireplace does nothing. Or it clicks for ten seconds and gives up. Or the pilot lights, you let go of the knob, and it dies. It sat for eight months in a Texas summer, and dust, spider webs and a tired thermopile are now between you and a warm living room.

Gas Fireplace Problems We Fix in Arlington Homes
Every gas fireplace, whether it is a direct-vent unit in a Viridian home or a gas log set in a 1960s brick fireplace near UTA, runs on the same handful of parts. When one fails, you get one of these symptoms.
| What you see | What usually failed |
|---|---|
| Pilot will not light at all | Pilot assembly clogged, gas supply closed, bad thermocouple |
| Pilot lights, then dies when you release the knob | Thermocouple worn out or loose at the valve |
| Pilot stays lit, main burner will not come on | Thermopile too weak, wall switch or receiver failed |
| Clicks but no flame | Igniter or spark electrode, dead batteries |
| Burner lights on one side only | Burner ports clogged with rust or soot, logs out of position |
| Flame is lazy, yellow and sooty | Dirty burner, logs misplaced, air shutter out of adjustment |
| Remote stopped working | Receiver batteries, receiver box, remote pairing |
| Smell of gas at the hearth | Loose fitting or valve. Close the valve and call Atmos first |
| Soot on the glass or walls | Burner or log placement, vent problem, dirty pilot |
| Fogged or cracked glass | Gasket worn, glass cracked from a hard knock or heat cycling |
Pilot and thermocouple repair. The thermocouple is the small probe sitting in the pilot flame. When it wears, the valve thinks the pilot is out and shuts the gas. We clean the pilot assembly, test the millivolt reading and replace the thermocouple on the spot.
Thermopile replacement. The thermopile makes the tiny current that opens the main burner valve when you flip the switch. A weak reading is the single most common reason an Arlington gas fireplace lights its pilot but never its burner. We carry common thermopiles on the truck.
Igniter and spark repair. Piezo igniters and electronic spark modules fail with age. We replace the electrode, module or batteries and reset the gap.
Gas valve service. We test the valve, clean the connections and replace it when it is truly failed. We do not replace a valve to cure a thermopile problem.
Burner and log cleaning. Rust and soot block burner ports and push the flame to one side. We pull the logs, clean the burner, set the logs back in the manufacturer’s pattern and adjust the air shutter so the flame is clean.
Remote and wall switch repair. New receivers, new remotes, re-pairing, and the wall switch wiring that a painter disconnected three years ago.
Glass, gasket and vent. New glass and gaskets for direct-vent units, and a check of the vent cap on the roof or wall for nests, rust and blockages.
For a gas log set that has crumbled, rusted or simply looks tired, see our gas log installation page. We refurbish older sets and install new vented and vent-free sets.
What Happens on a Free Gas Fireplace Service Call
- Call or send the form. Tell us the brand if you know it (the rating plate is usually under the bottom louver or behind the glass). The service call is free.
- We test the whole ignition chain. Gas supply at the fireplace valve, pilot flame, thermocouple and thermopile readings in millivolts, igniter spark, wall switch, receiver and remote.
- We look at the firebox and vent. Burner ports, log placement, soot, rust, the glass gasket, and the vent termination outside.
- Carbon monoxide check. A reading at the hearth with the unit running.
- You see what failed. Photos and a plain explanation. If it is a five-minute thermocouple swap, we say so.
- Written price, then the repair. Most gas fireplace repairs in Arlington are finished on the first visit because we carry the common parts.

What moves the price: the brand and whether the part is still made, whether the valve or receiver has to be ordered, and whether the vent or firebox needs work too. Seniors get 10% off, veterans and first responders get 10% off, and we match written quotes from insured companies. One discount per job.
Gas Lines: What Texas Law Requires
Texas law requires a licensed plumber for gas line installation and repair, and that is the right rule. Crownline works from the fireplace shutoff valve inward. If we find a leak on the supply line, a pressure problem, or a fireplace that was never piped correctly, we stop, show you, and help you get a licensed plumber out. Be wary of any fireplace company that offers to work on the gas line itself.
Gas Fireplace Safety in Arlington Homes
A gas fireplace that burns yellow, soots the glass or smells is not just annoying. Incomplete combustion makes carbon monoxide, and a blocked vent sends it into the room. The National Fire Protection Association’s carbon monoxide safety guidance calls for CO alarms outside each sleeping area and on every level of the home, tested monthly. We check for a CO alarm on every service call and take a reading at the hearth with the fireplace running.
Vent-free gas logs deserve a special mention. They are common in Arlington homes built in the 1990s and 2000s. They run clean when the burner is clean and the logs are placed exactly right. When the logs are shifted or the burner is dusty, they soot and smell. If yours does, stop using it until it has been serviced.
A Yearly Gas Fireplace Service Prevents Most Repairs
Almost every emergency call we take in Arlington in November could have been a ten-minute fix in September. A yearly service includes cleaning the pilot assembly and burner, testing the thermocouple and thermopile, checking the glass gasket, vacuuming the firebox and checking the vent. We tell you which parts are getting weak so you can replace them on your schedule, not on the coldest night of the year.
Book it with a fireplace inspection in Arlington and the whole system gets checked in one visit: firebox, damper, logs, glass doors, clearances and carbon monoxide risk. If the logs and glass are sooty, our fireplace cleaning service handles that in the same trip. And since we are already in the house, dryer vent cleaning is $89.
Gas Fireplaces Across Arlington, TX
Arlington’s gas fireplaces split by neighborhood and decade. The 1950s and 1960s brick homes around Old Arlington and UTA mostly have masonry fireplaces with a gas log set added later, often with a safety clamp holding the damper open. The 1980s to 2000s two-story homes in Southwest Arlington, Interlochen and near Lake Arlington have factory-built gas fireplaces, many of them vent-free. Newer homes in Viridian, North Arlington and around the Arlington Highlands have direct-vent units with electronic ignition and remotes. Our crew knows all three, and we carry the parts for the common ones.
We serve every Arlington ZIP code, Dalworthington Gardens and Pantego from our office at 700 Highlander Blvd, so we are usually close by.
