Yearly Gas Fireplace Service
A gas fireplace has no ashes to clean, but its pilot, burner, glass seal and vent still need a yearly look. The service is priced at the free inspection, before any work.
Nicor Gas tells customers to have their gas appliances inspected at least once a year, and NFPA 211 says the same about chimneys, fireplaces and vents. A gas fireplace burns clean compared with wood, so it's easy to forget. Over a season, though, dust and lint build up in the pilot and burner, the glass gathers a white film, gaskets dry out, and nests or debris can settle in the vent.
Gas fireplaces are common across the newer suburbs, where many homes were built in the late 1980s and 1990s, and around 75 to 91 percent of homes in the area heat with gas (Census ACS 2020–24). A short yearly service keeps the flame clean and the vent clear, and it catches worn parts before they leave you with a cold fireplace in January.
Signs you need this
- A white or gray haze on the inside of the glass
- A flame that has turned yellow or uneven
- Soot on the logs or the top of the opening
- A pilot that's hard to light at the start of the season
- A vent outside covered by snow, leaves or a nest
How we do it
- Free inspectionWe check the pilot, burner, logs, glass, gaskets, controls and the vent, and give you the service price before any work.
- Clean and adjustWe vacuum the firebox and burner, clean the pilot assembly, clean the glass, and set the logs back in their correct places.
- Check seals and ventWe look at the glass gasket and the vent run outside, clearing any blockage at the termination.
- Run and checkWe light the unit, watch the flame through a full cycle and check our connections for leaks.
Snow over a vent can cause carbon monoxide
Many gas fireplaces vent straight out the side wall rather than up a chimney. Nicor Gas warns that snow or ice covering a gas vent or meter can cause a dangerous carbon monoxide buildup, and asks people to clear them by hand or with a broom, not a shovel. After a heavy snow, or when wind piles drifts against the house, check the vent before you use the fireplace.
Lake-effect snow can drop a lot in one night. In the November 2025 event the National Weather Service in Chicago logged 10.0 inches at Winthrop Harbor and 5.2 inches near Evanston.
Carbon monoxide alarms
Illinois law requires a CO alarm within 15 feet of every room used for sleeping in homes with a fossil-fuel heater, a fireplace or an attached garage. In Chicago, a bedroom that has a gas fireplace needs an alarm inside the bedroom too. An alarm is not a substitute for the yearly check; Nicor says the same.
What the service costs
The yearly gas fireplace service is priced at the free inspection, before any work. If we find a worn part, such as a thermocouple or igniter, we show it to you and price it separately; nothing is replaced without your go-ahead.
FAQ
Gas Fireplace Service questions
Does a gas fireplace need to be serviced every year?
Yes. Nicor Gas advises having gas appliances inspected at least once a year, and NFPA 211 calls for yearly inspection of fireplaces and vents. A gas fireplace still collects dust, and its vent can still block.
Does a gas fireplace need a chimney or vent?
Most do. Direct-vent units vent through the wall or roof, and others use a chimney. Whatever it uses, the vent must stay clear, and Nicor warns that snow over a gas vent can cause CO.
Why is the glass on my gas fireplace cloudy?
A white film from combustion builds up on the inside of the glass over a season. It cleans off with the right glass cleaner during the service, and heavy haze can point to a flame problem worth checking.
Why does my new fireplace smell like burning plastic?
A new unit often smells for its first few hours of use while paints and coatings cure. A burning smell from an older unit is different, and we'd check it.
Does a gas fireplace need electricity?
It depends on the model. Some need power for the ignition, fan or remote, and some run on a standing pilot without it. We tell you which kind you have.
