Repair or Replace?
Not sure whether to repair or replace your furnace? We provide honest, unbiased recommendations.

Frequently Asked Questions
How quickly can you come out for a furnace repair?
We offer same-day service for most furnace repairs. For emergency situations, we have technicians available around the clock. Call (312) 600-2222 and we will get someone out to you as quickly as possible.
How much does furnace repair cost?
Furnace repair costs vary depending on the issue. Minor repairs such as a flame sensor cleaning or ignitor replacement typically run $150–$350. More complex repairs involving motors or control boards can range higher. We always provide upfront pricing before any work begins.
My furnace is blowing cold air — what is wrong?
Cold air from a furnace is usually caused by a faulty ignitor, a dirty flame sensor, a tripped limit switch, or a problem with the thermostat. Our technician will diagnose the exact cause and provide a repair quote on the spot.
Do you offer a warranty on furnace repairs?
Yes. All of our furnace repairs are backed by a parts and labor warranty. We stand behind our work and will make it right if any issue arises after the repair.
