Furnace not running? Start here
Smell gas? If you smell gas, leave right away and don't use phones, switches or anything that could spark. Once you're outside and a safe distance away, call Nicor Gas at 888-642-6748 or 911. Don't try to find or stop the leak yourself.
- Check the thermostat: heat mode, setting above room temperature, fresh batteries.
- Check the breaker for the furnace and the switch near it that looks like a light switch.
- Pull the filter. If it's caked with dust, replace it.
- After heavy snow, check that outdoor vent pipes on a high-efficiency furnace aren't blocked. A blocked vent can shut one down, but clearing it won't fix every no-heat problem.
- Don't take apart burners, igniters or gas valves yourself. Those are jobs for the company you choose.
If the furnace is 15 to 20 years old and the repair is large, compare a repair quote with a replacement quote. The furnace repair page explains common failures like igniters and flame sensors, and the furnace repair cost guide lists published national ranges.
Paperwork worth asking for
In Illinois, a home repair contractor must give you a written contract before starting work over $1,000, plus the state pamphlet "Home Repair: Know Your Consumer Rights." Questions or problems: Illinois Attorney General, 1-800-386-5438. Small repairs under $500 may be outside the Act. For permits on a furnace replacement, check with the village's building department or have the contractor confirm.
Niles furnace questions
Are Niles furnaces mostly gas?
Yes. About 82.4% of Niles homes heat with utility gas and about 14.7% with electricity (ACS 2020–2024). Nicor Gas's territory filing lists Niles, so for a gas smell, leave and call Nicor Gas at 888-642-6748 or 911 from a safe place.
Can a company from Park Ridge work on my furnace in Niles?
Often, yes. Many heating companies cover several neighboring towns. Illinois doesn't issue a statewide HVAC license, and each town sets its own rules, so ask the company what the Village of Niles requires and for proof of insurance.
Who is responsible for heat in a Niles rental?
Check your lease and put repair requests to the landlord in writing. In rentals, Illinois law has the owner install carbon monoxide alarms and the tenant test them and change batteries. Renters can request quotes, but the landlord usually decides on the repair.
