Gas Fireplace Tune-Ups in DeKalb, IL
A gas fireplace still needs a yearly service — cleaning, a venting check, and a safety inspection of the burner, pilot and gas valve. We tune up gas fireplaces and replace worn gas valves across DeKalb County.
A gas fireplace tune-up is an annual cleaning and safety check of the burner, logs, pilot assembly, venting and gas controls. Gas produces little creosote, but soot, dust and spider webs clog burner ports, glass hazes over, and gas valves and thermocouples wear out. A yearly tune-up keeps the flames clean, the venting clear, and — most importantly — confirms there are no gas or carbon-monoxide hazards. Imperial services gas fireplaces and inserts throughout the DeKalb area.
What a tune-up includes
We clean the burner, logs and glass, vacuum the firebox, check and adjust the pilot and flame, test the thermocouple and thermopile, confirm the venting is clear, and check for gas leaks and proper carbon-monoxide safety. You end up with a fireplace that lights reliably and burns clean.
Gas valve replacement
The gas valve controls the flow of gas to your fireplace, and a worn or failing valve is a safety issue — not a DIY repair. Warning signs include the smell of gas near the fireplace, a fireplace that won’t light or stay lit, a stuck or hard-to-turn key valve, or a pilot that keeps going out. We diagnose the valve, and when it needs replacing we install the correct valve for your unit and leak-test the connection. Gas valve work should always be done by a qualified technician — if you smell gas, leave the area and call us or your gas utility right away.
Carbon monoxide and safety
A blocked vent or a failing seal can push carbon monoxide back into the room. Part of every tune-up is confirming the fireplace vents correctly and burns cleanly. We recommend a working CO alarm on every level of the home as a backstop.
Why an annual service pays off
Skipping service is how a small issue — a dirty pilot, a weak thermocouple, a stiff valve — becomes a no-heat night in January. A yearly tune-up catches wear before it strands you, and keeps the unit efficient.
Venting types: B-vent vs. direct-vent
Gas fireplaces vent in a few different ways, and knowing which you have matters for safety. A natural- or B-vent unit relies on the buoyancy of warm exhaust to carry gases up and out; a direct-vent unit uses a sealed, two-pipe system that draws combustion air from outside and exhausts through the same terminal, keeping the burn isolated from your room air. Each has specific clearance and termination requirements, and each can fail in ways that let carbon monoxide back inside. Part of every tune-up is confirming the venting is intact, clear and terminating correctly for your unit’s type.
The gas valve, explained
The gas valve regulates the flow of gas to the burner, and it is not a part to take chances with. A worn or failing valve can leak, stick, or refuse to open or close fully — and the warning signs are a gas smell near the fireplace, a unit that will not light or stay lit, a stuck key valve, or a pilot that keeps dropping out. If you ever smell gas, leave the area and call us or your gas utility from outside; do not attempt a repair. When a valve needs replacing, we install the correct valve for your model and leak-test the connection. Gas valve work belongs to a qualified technician, full stop.
Carbon monoxide and clean combustion
Because gas burns cleanly, a problem gives little visible warning, which is exactly why the annual check matters. During a tune-up we confirm the burner and pilot are burning completely and correctly, that the flame pattern is right, and that the venting carries exhaust fully out of the home. A dirty burner, a failing seal or a blocked vent can shift combustion and produce carbon monoxide. We recommend a working CO alarm on every level of the home as an independent backstop — the two layers together, a verified clean burn and a tested alarm, are what keep a gas fireplace genuinely safe.

Good to Know
Frequently asked questions
Does a gas fireplace really need annual service?
Yes. Burners clog, glass hazes, and pilots, thermocouples and gas valves wear out. A yearly tune-up keeps it lighting reliably and confirms it is venting safely.
My gas fireplace won’t light — what’s wrong?
Common causes are a dirty or failed pilot, a weak thermocouple, or a worn gas valve. We diagnose the exact cause and fix it rather than guessing.
When does a gas valve need to be replaced?
When it leaks, sticks, won’t fully open or close, or the fireplace won’t light despite a good pilot. Signs include a gas smell, a stuck key valve, or a pilot that won’t stay lit.
I smell gas near my fireplace — what should I do?
Treat it as an emergency: leave the area, don’t flip switches, and call us or your gas utility from outside. Do not attempt a gas valve repair yourself.
Can you clean the glass and logs?
Yes — cleaning the glass, logs and burner is part of every tune-up, and we reset the logs to the manufacturer’s layout for a correct flame.
Do gas fireplaces produce carbon monoxide?
They can if venting is blocked or the unit burns incorrectly, which is exactly what a tune-up checks for. A working CO alarm on each level is strongly recommended.
How long does a tune-up take?
Most gas fireplace tune-ups take about an hour, longer if we find a valve or pilot component that needs replacing.
Are you insured and bonded?
Yes — Imperial Chimney Sweepers is fully insured and bonded. Gas valve work is done by a qualified technician.
