First, check your thermostat is set to 'Heat' and the temperature is set above room temperature. Check your circuit breaker and make sure the furnace power switch is on. Check or replace your air filter if it's dirty. If none of those fix it, call us — it could be an igniter, flame sensor, or control board issue.
We offer 24/7 emergency furnace repair in New Lenox. For urgent situations, we prioritize no-heat calls especially in winter. Call (815) 605-7365 and we'll get a technician to you as quickly as possible.
It depends on the noise. A banging or booming sound could indicate a dangerous delayed ignition — turn it off and call us immediately. A squealing sound usually means a belt or bearing issue. A rattling sound may just be a loose panel. When in doubt, call us — we'll tell you if it's safe over the phone.
Most furnaces in Illinois last 15–20 years with proper annual maintenance. If your furnace is over 15 years old and needs a major repair, replacement is often the more cost-effective choice. We'll give you an honest assessment.
