Gas Fireplace Inspection - Northwest Chicago Suburbs
"A gas fireplace that looks fine can still have a failing thermocouple, a cracked heat exchanger, or a venting problem. Annual inspection catches what you can't see."
Looking for gas fireplace inspection near you? GEM Chimney & Duct provides annual gas fireplace safety inspections across the northwest Chicago suburbs — same-day scheduling, upfront pricing, and honest work. We inspect gas fireplaces, gas log sets, and gas inserts in homes throughout Wheeling, Buffalo Grove, Northbrook, Glenview, Arlington Heights, and the surrounding area. If you smell gas, leave the home and call 911 or your gas utility immediately.
Gas fireplaces can produce carbon monoxide if the venting system is compromised or the burner is not operating correctly. Carbon monoxide is odorless and colorless — you cannot detect it without a CO detector. Annual inspection of the venting system and combustion components is the only way to confirm your gas fireplace is operating safely. If you smell gas, leave the home and call 911 or your gas utility immediately.
What Is Gas Fireplace Inspection?
A gas fireplace inspection is a systematic safety and performance check of all components of your gas fireplace system — the burner, pilot assembly, thermocouple and thermopile, gas valve, ignition system, venting, glass and gasket seal, and the surrounding firebox. We test each component for proper operation and inspect the venting system for blockages, cracks, or improper installation.
Gas fireplaces are generally safe and reliable, but they require periodic inspection to confirm that safety-critical components are functioning correctly. A failing thermocouple can allow gas to flow without ignition. A cracked venting system can allow carbon monoxide to enter the home. A clogged burner produces incomplete combustion and soot. Annual inspection catches these issues before they become emergencies.

Gas Fireplace Inspection in the Chicago Area: What You Need to Know
The northwest Chicago suburbs have a large stock of gas fireplaces installed in the 1990s and 2000s — units that are now 20–30 years old and approaching the end of their designed service life for key components. Thermocouples and thermopiles typically last 5–10 years. Gas valves last 15–20 years. Venting systems can develop cracks and gaps over decades of thermal cycling. In Northbrook, Deerfield, Highland Park, and Libertyville, we regularly find gas fireplaces that haven't been inspected since installation — a significant safety concern.
Expert Tip from GEM
If your gas fireplace has a standing pilot (a small flame that burns continuously), check it monthly. A healthy pilot flame is steady and blue with a small yellow tip. A weak, flickering, or orange pilot flame indicates a problem with the thermocouple, gas pressure, or pilot orifice. Don't ignore it — a failing pilot is often the first sign of a larger issue.

Our Gas Fireplace Inspection Process
Visual inspection
We inspect the firebox, burner, log set or media, glass and gasket seal, and all visible components for damage, wear, or improper installation.
Pilot and ignition testing
We test the pilot assembly, thermocouple and thermopile (millivolt test), and ignition system for proper operation and output.
Gas valve and pressure testing
We test the gas valve for proper operation and check gas pressure at the appliance.
Venting inspection
We inspect the venting system — direct-vent, B-vent, or vent-free — for blockages, cracks, improper connections, and proper termination.
Burner and port cleaning
We clean the burner ports and pilot orifice to ensure complete combustion and a proper flame pattern.
Written report
We provide a written inspection report documenting what was checked, what was found, and any recommended repairs — with upfront pricing for any work needed.
