Expert diagnosis and repair for gas log fireplaces, direct-vent inserts, and ventless gas units that will not light, stay lit, or heat properly.
A gas fireplace that will not ignite, shuts off unexpectedly, produces a strange odor, or heats unevenly needs professional diagnosis. The problem could be as simple as a failed thermocouple or as complex as a cracked heat exchanger. Eco Grizzly technicians are trained to service all major gas fireplace brands. We are a licensed California contractor (license 1077111) serving greater Los Angeles since 2022, and we carry common replacement parts on our trucks for same-visit repairs whenever possible.
If your gas fireplace will not turn on, the pilot keeps going out, the flame is weak or yellow instead of blue, the glass is sooty or cracked, the remote no longer works, or you notice a gas odor, it is time to schedule service. Ignoring these symptoms can turn a simple repair into a full unit replacement, and a gas smell should always be treated as urgent. We diagnose all of these symptoms and quote the fix before any work begins.
Pilot will not light: often caused by a failed thermocouple, thermopile, or clogged pilot orifice. Pilot lights but main burner does not ignite: usually a thermopile voltage issue or a faulty gas valve. Unit shuts off after a few minutes: the ODS (oxygen depletion sensor) may be triggering, or the high-limit switch may be tripping due to restricted airflow. Strange odor: could indicate a gas leak, dust burning off, or a venting problem. Cracked glass: must be replaced with manufacturer-specified tempered ceramic glass.
Every gas fireplace service starts with a diagnostic visit that includes a full inspection, gas pressure measurement, and millivolt testing. You receive a written estimate before any repair begins, so there are no surprises. Most repairs are completed in the same visit, and if a part must be ordered we schedule the return as soon as it arrives.
We begin with a full diagnostic that includes visual inspection, gas pressure measurement, millivolt testing of the thermocouple and thermopile, and a combustion analysis. Once we identify the root cause, we provide a written estimate before starting work. Most repairs are completed during the initial visit. We test all safety controls before leaving and verify proper flame characteristics.
We service gas fireplaces from all major manufacturers. If you have a discontinued model, mention the nameplate when you call and we'll confirm whether we can source a compatible replacement part or recommend a modern equivalent.

From the Field
Real Results

BeforeSouthern California
This homeowner wanted to enjoy their fireplace without the hassle of wood and cleanup. We inspected the existing firebox and flue for gas-log compatibility, ran the gas line to the firebox with a hidden shut-off valve, and installed a premium vented gas log set with a realistic ceramic fiber log arrangement and glowing ember media. The result looks exactly like a wood fire but lights with a wall switch and requires zero cleanup.
BeforeSouthern California
The existing gas log set had discolored and the ceramic logs had cracked after years of use. Our technicians safely disconnected the old set, replaced the burner tube, and installed a new premium vented log set with fresh ember media and an upgraded burner for a taller, more realistic flame pattern. The homeowner was immediately impressed by the improvement in appearance and flame quality.
BeforeSouthern California
The homeowner wanted to reduce heat loss and update the look of their masonry fireplace. We measured the firebox opening, sourced a correctly-sized bi-fold glass door set with a matte black frame, and completed the installation in a single visit. The doors open fully for use with a fire and close tight when the fireplace is not in use, stopping the constant draw of conditioned air up the chimney. The finished result is clean, functional, and a clear upgrade over the original open firebox.
Cast Stone MantelSouthern California
This home had two fireplaces, and both were fitted on the same visit. In the room with the carved cast stone mantel, our crew set the logs and grate inside the brick firebox and spread a fresh bed of black lava rock across the floor of the opening. At the second fireplace, with its tall arched stone surround and herringbone brick firebox, we fitted a matching log set on its own steel grate. Each set was lit and the flame pattern checked across every log before we wrapped up. The drop cloths and lava rock bucket visible in these shots are ours, taken while the crew was still on site.
