Professional Gas Fireplace Repair & Servicing

Gas fireplaces, log sets, and inserts offer clean, effortless heat at the flip of a switch or click of a remote. However, despite their low-maintenance reputation, gas appliances rely on complex electronic ignition systems, delicate safety sensors, precision gas valves, and sealed glass enclosures. When soot accumulates or electrical components degrade, your gas fireplace can stall, shut off unexpectedly, or pose dangerous gas leak and carbon monoxide hazards.

Our certified gas technicians specialize in diagnosing, repairing, and tuning vented and vent-free gas fireplaces, inserts, and gas log sets.

Our Diagnostic & Gas Repair Services

We service all major brands (including Heatilator, Majestic, Superior, Mendota, Regency, Empire, Valor, and Napoleon) using original manufacturer (OEM) replacement parts:

Thermocouple & Thermopile Replacement

The thermocouple and thermopile are thermal safety sensors that detect the pilot flame and generate millivoltage to hold the gas valve open. We replace worn sensor probes to restore instant, reliable ignition.

Pilot Assembly & Burner Port Cleaning

Over time, dust, cobwebs, and chemical corrosion clog the tiny pilot orifice and main burner ports. We clean, de-scale, and calibrate the pilot assembly for smooth flame transfer.

Gas Valve & Control Module Repairs

We test electrical millivolts, solenoid resistance, and gas pressure manifolds, replacing faulty gas control valves, wall switches, receivers, and remote modules.

Glass Restoration & Gasket Replacement

We remove stubborn white mineral haze from ceramic glass using non-abrasive gas glass cleaners, inspect high-temp door rope gaskets, and ensure the firebox forms a safe, direct-vent vacuum seal.

Gas Fireplace Safety: Carbon Monoxide & Venting

Because gas burns so cleanly, many homeowners assume gas fireplaces don’t require safety maintenance. However, incomplete gas combustion creates carbon monoxide (CO), a colorless, odorless, and deadly gas.

Frequently Asked Questions

Why does my gas fireplace turn on, but shut down after a few minutes?
A failing thermopile or an unstable pilot flame typically causes this. When the thermopile degrades, it fails to produce sufficient millivoltage (350 mV to 750 mV) to keep the main gas valve open. As the safety circuit cools, the valve automatically snaps shut to prevent unburned gas accumulation.
Gas fireplaces should be professionally inspected and serviced once every year. Annual maintenance prevents dust accumulation inside burner controls, ensures proper glass sealing, and verifies that toxic exhaust gases vent safely out of your home.
Black soot indicates incomplete combustion, meaning the air-to-gas ratio is out of balance. This is caused by misplaced ceramic logs blocking burner ports, clogged primary air shutters, or improper gas pressure. Soot accumulation requires immediate professional adjustment.
No, never use Windex or ammonia-based cleaners. Standard household glass cleaners contain chemicals that can etch into hot ceramic glass, causing permanent cloudiness or shattering under high heat. Use only specialized, non-abrasive gas fireplace glass cleaners.
Most traditional standing-pilot and millivolt gas fireplaces operate completely independently of household electricity! The pilot light generates its own millivoltage to operate the wall switch or remote. Units with electronic intermittent pilot ignition (IPI) often feature battery backup trays for power outages.
