At Nicor Gas, the safety of our customers and communities is always our highest priority. Natural gas is a safe, reliable energy source when used properly, but working on gas appliances or equipment yourself can put you and others at serious risk.
Natural Gas Appliance & Leak Safety
Following these guidelines helps protect you, your family and your community, and ensures your natural gas appliances continue to operate safely and efficiently.
- Never attempt to install, repair or move a natural gas appliance or meter on your own.
- Always use a qualified contractor or licensed professional for appliance installation, maintenance or repair.
- Keep the area around your natural gas meter and appliances clear of debris and accessible at all times.
- Do not try to locate or stop a leak yourself, and avoid using electrical devices, phones or open flames near a suspected leak.
- If you notice damage, smell natural gas or hear a hissing sound, leave the area immediately and call 911 and Nicor Gas at 888.Nicor4U 888.642.6748 from a safe location.
Furnace & Venting Safety
Important information about furnaces according to the Federal Emergency Management Agency:
- It’s important that you have your furnace inspected by a qualified specialist according to manufacturer guidelines to ensure that it is in good working condition. Do not attempt repairs yourself unless you are qualified.
- Be sure all furnace controls and emergency shutoffs are in proper working condition.
- Keep trash and other combustible material away from your heating and water heating systems.
- Keep natural gas vents unobstructed and free of debris. Some direct-vent and high-efficiency appliances have direct side wall outdoor vents and air intakes that could become obstructed during heavy snowfalls.
- Keep sidewall vents clear of snow and ice. These vents bring in fresh air and safely release exhaust from heating and water-heating equipment. Blocked vents can disrupt airflow and allow carbon monoxide-containing exhaust to enter the home.
Heating System Warning Signs
- Gas flames are pale yellow or wavy
- Gas appliances are not vented to the outdoors
- Rust, corrosion or excessive dust on gas appliances
- Excessively dirty, clogged or missing furnace air filters
- Gas appliance valves are missing or not properly installed
- Blocked, broken, rusted, disconnected, corroded or unsealed appliance vent piping
- Soot near burners or appliance venting
- Venting not approved by the appliance manufacturer or not venting to the proper place outdoors
- Evidence of discoloration at the appliance burner, burner access door or vent area
- Gas appliances installed in a garage less than 18 inches above the garage floor
- Gas appliances that are missing a fire door
Water Heater Safety
The U.S. Consumer Product Safety Commission recommends setting water heaters to 120°F (49°C) to help reduce the risk of scalding. Always test the water before bathing children or infants.
Consumers should consider lowering the thermostat to the lowest settings that will satisfy hot water needs for all clothing and dish washing machines.
How to test your water temperature:
- Run the hot water for five minutes.
- Put a reliable thermometer that registers at least 150 degrees under the water stream.
- If your water is more than 125 degrees, lower the thermostat on your water heater. If you can't find the temperature controls or have any questions, call a qualified contractor or your landlord for help.
Natural Gas Detector Safety
Natural gas detectors may be installed by homeowners for an additional safeguard to detect leaks. The natural gas detector measures the concentration of methane in the air and sounds an alarm to alert you before dangerous levels are reached.
The methane detector works by pulling in air from the surroundings and, if it detects a dangerous level of natural gas in your home its light will flash and/or it will emit a loud noise. Please refer to your user’s manual for the detector for specific natural gas alarm characteristics. It’s also important to test the device regularly. Please refer to your user’s manual for testing intervals and the procedures that explain the light and sound patterns to ensure the detector and alarm functions are working properly.
If the natural gas detector alarm sounds, respond immediately!
Assume there’s a natural gas leak. Leave the area quickly, taking everyone with you.
Follow the guidelines for when you smell gas:
DO NOT use the telephone or any electrical appliances including light switches, garage door openers, doorbells, radios, TVs or cell phones. A spark from any of these sources could ignite the gas, causing a fire or explosion.
DO NOT disconnect the gas detector battery to silence the alarm. A spark could cause an explosion.
DO NOT assume someone else will report the leak.
DO NOT go back inside your home or building until company or emergency personnel say it is safe to return.

Furnace Filters
Finding the Right Filter
Furnace filters may be easy to overlook, but they play an important role in protecting your heating system and maintaining indoor air quality. They help keep dust and debris away from the blower fan and compressor. Replacing filters regularly can also support proper airflow and help your furnace operate efficiently. Always check your equipment instructions for the recommended filter type and replacement schedule.
