Furnace Repair Chicago

It depends on the part and the problem. Minor fixes — igniters, flame sensors, capacitors — sit at the lower end, while major components like blower motors, control boards, or heat exchangers cost more. You'll get a written, upfront price after diagnosis, never a guess. Eco Home Program members save 10% on qualifying repairs and $50 off the diagnostic fee, with no overtime charges on covered visits.

Yes. No-heat calls are our top priority through Chicago winters, and we offer same-day emergency windows when available. Call (224) 253-8131 or book online — a live person answers, not a machine.

• Thermostat set to "Heat" and above room temperature
• A clean filter installed
• Furnace switch and circuit breaker on
• Vents and cold-air returns unblocked
• Note any blinking error code on the unit

If you spot obvious flue issues or smell anything burning, leave the system off and call us.

Common Chicago-winter culprits are a dirty filter choking airflow, a dirty flame sensor, a clogged condensate drain, or an overheating safety limit shutting the burner down. Our guide to common furnace problems covers the symptoms and fixes, and a technician can pinpoint the root cause fast.

Drafts, a dirty thermocouple, a weak igniter, a failing gas valve, or venting problems are the usual suspects — and older Chicago homes with retrofit venting see this more often. Our pilot light troubleshooting guide explains the causes; we'll confirm the fix and exact cost after diagnosis.

No — shut it off and call right away. A cracked heat exchanger can leak carbon monoxide into your home. We run a full combustion and safety analysis and recommend repair or replacement based on code and your safety, never guesswork.

Leave the house immediately and call 911 or your gas utility — Peoples Gas or Nicor Gas — from a safe location. Don't flip switches, relight anything, or run the system. Once the utility clears your home, contact Eco Temp HVAC for a full safety inspection.

Under roughly 12–15 years old, repair usually makes sense. Past that — or if you're facing a major repair like a heat exchanger, or paying high Nicor/Peoples Gas bills from an aging low-efficiency unit — replacement can be the smarter long-term call. We give you an honest repair-vs-replace breakdown, never a pressured upsell.

Often, yes. Chicago bungalows, two-flats, and greystones frequently have ductwork converted from old gravity systems, tight mechanical closets, retrofit venting, and older gas lines — all of which affect how a furnace runs and how it's repaired. Our technicians work in these homes constantly and know exactly what to look for.

Most furnace repairs don't require a permit. A full furnace replacement in Chicago does, and we handle the permit filing, fees, and inspection for you as part of the installation — you don't have to navigate the city process yourself.

Most repairs are done in about 60–120 minutes once the part is on hand. Our trucks stock common parts for the brands found in Chicago homes, so many repairs finish in a single visit; special-order components take longer, and we keep you updated at every step.

We service most major brands — Carrier, Trane, Lennox, Rheem, Goodman, Bryant, Amana, American Standard, York, and more. For ductless or heat pump heating issues, we cover those too.

Most manufacturers require documented annual maintenance to keep the warranty valid — skip it and you can void coverage. We document every visit for your records, and an annual furnace tune-up keeps you ahead of mid-winter breakdowns.
