Common Furnace Problems We See and Repair
Is your furnace refusing to turn on? Blowing cold air when it should be heating? Making a banging, rattling, or high-pitched noise it didn't used to make? Those symptoms usually trace back to a handful of common failures — and most of them are repairable, often the same day.
We service all major furnace brands, including Carrier, Lennox, Trane, Goodman, and others. If you have a furnace, we work on it.
What We Commonly Find When a Furnace Stops Working
Most furnace breakdowns in this area come down to a short list of known failure points. Here's what we diagnose and repair regularly:
- Failed ignitor — One of the most frequent causes of a furnace that won't light. The ignitor wears out over time and is a straightforward repair.
- Dirty or faulty flame sensor — A sensor coated in residue will shut the furnace down as a safety measure. Cleaning or replacing it typically restores normal operation.
- Faulty limit switch — When this component fails, the furnace may overheat and shut off repeatedly or blow only cold air.
- Failed blower motor — If air isn't moving through your vents, the blower motor may have given out. We diagnose and replace these on all major brands.
- Cracked heat exchanger — A serious issue that affects both heating performance and carbon monoxide safety. We'll tell you honestly whether repair is viable or whether replacement is the right call.
- Thermostat calibration issues — Sometimes the furnace itself is fine and the problem is a miscommunicating thermostat. We check the full system, not just the obvious parts.
A diagnostic call gives you a clear answer: what's wrong, what it costs to fix, and whether the repair makes sense given the age and condition of your system.
24/7 Emergency Furnace Repair — Including Nights, Weekends, and Holidays
When your furnace quits at 2 a.m. in January, you don't want to leave a voicemail and wait until Monday. You want someone who picks up.
Joel answers his phone directly — not a call center, not an answering service. If you're in Schaumburg, Streamwood, Bartlett, Hanover Park, Elgin, or the surrounding northwest suburbs, we can get to you on short notice, around the clock.
Emergency call, same honest price. You shouldn't get charged triple because your furnace picked a bad night to quit. Our rates on common repairs — ignitors, flame sensors, limit switches — run significantly below what large regional chains typically charge. A part that costs $400–$500 at a big company costs $150 here.
We Repair Furnaces. We Don't Push New Ones.
If a repair makes sense, that's what we recommend. Full stop.
JDT was built around a specific moment: we walked away from a job that would have netted a $10,000 system sale because the homeowner's furnace didn't need to be replaced. That decision defines how we operate. If your furnace has a failed ignitor, we replace the ignitor. If it has a cracked heat exchanger and is 25 years old, we'll tell you that honestly too — and explain why replacement makes more sense in that case.
You get the real answer, not the one that's better for our revenue.

Furnace Repair Questions, Answered Plainly
Straight answers before you schedule
How much does furnace repair cost in Illinois?
Most furnace repairs in the northwest suburbs fall between $150 and $600, depending on the part and the complexity of the job. A flame sensor cleaning or ignitor replacement sits at the lower end. A blower motor or control board replacement runs higher. We give you a firm price before any work begins — no surprises on the invoice.How long does furnace repair take?
Most repairs are completed in a single visit, typically one to two hours. If a part needs to be ordered, we'll tell you upfront and give you a realistic timeline. We don't leave you without heat and a vague "we'll be back" answer.What do I do when my furnace stops working in the middle of the night?
Call us. Joel answers directly, 24 hours a day, seven days a week, including holidays. We cover Schaumburg, Streamwood, and the northwest Chicago suburbs on short notice. Don't wait until morning when it's 15 degrees outside.When should I repair my furnace instead of replacing it?
As a general rule, if your furnace is under 15 years old and the repair cost is less than half the price of a new system, repair is usually the right move. If the heat exchanger is cracked, the system is 20-plus years old, or you've had multiple failures in a short window, replacement may be the more honest answer. We'll walk you through the math either way and let you decide.Do you service my furnace brand?
Yes. We repair all major brands, including Carrier, Lennox, Trane, Goodman, Rheem, and others. You don't need to find a brand-specific technician — we work on whatever you have.
