Repair-First Approach
Owner-Operated
Furnace Service You Can Count On When It Counts Most
Chicago-area winters don't leave room for slow responses. When overnight lows hit the teens and wind chills drop below zero, a furnace failure isn't an inconvenience — it's an emergency. JDT provides heating service across the northwest suburbs with 24/7 availability, direct owner contact, and a repair-first approach that puts your outcome ahead of the bigger ticket.
JDT is a small, owner-operated heating company. When you describe what's happening, you're talking to someone with direct accountability for how the job gets handled — not a dispatcher passing your information down a chain. That matters most at midnight in January..
Heating Services We Provide
Furnace Repair
From ignitor failures and pressure switch issues to heat exchanger problems and short-cycling, we diagnose furnace problems accurately and quote the repair before starting. We service all major brands — Carrier, Lennox, Trane, Rheem, Goodman, and others — and approach every call with the intent to fix the system in front of us, not sell a new one.
Furnace Installation
When a furnace genuinely needs replacing — age, failed heat exchanger, or repair costs that don't pencil out — we help you choose the right system for your home's size, layout, and budget. No upsell. No oversized equipment pushed to pad a ticket. The right unit, installed correctly.
Ductless Heating Systems
Mini-split systems provide efficient zone heating for additions, older homes without ductwork, and spaces your central system doesn't reach well. JDT installs and services ductless systems throughout the northwest suburbs.
HVAC Maintenance and Tune-Ups
A furnace tune-up before winter is the most reliable way to avoid a mid-January breakdown. Our maintenance plans include seasonal inspections, cleaning, and the small adjustments that prevent large repairs.
Signs Your Furnace Needs Service
Don't wait for a complete failure. These are the warning signs that something is wrong with your heating system — and the sooner they're addressed, the less expensive the fix is likely to be.
- No heat or insufficient heat. If your furnace runs but the air coming out isn't warm, or rooms aren't reaching the set temperature, something is wrong with the system — not just the thermostat.
- Short-cycling. A furnace that turns on and off repeatedly without completing a full heating cycle is working harder than it should and wearing out faster. Common causes include a dirty filter, a failing flame sensor, or an oversized system.
- Unusual sounds. Banging, rattling, squealing, or grinding during operation are not normal. Each points to a different mechanical issue — most of which are repairable when caught early.
- Rising utility bills without a usage change. A furnace losing efficiency draws more energy to produce the same heat. If your gas bills are climbing without a clear reason, the system deserves a look.
- Uneven heating across rooms. If some rooms are warm and others stay cold despite a running furnace, the issue could be the system, the ductwork, or both.
- Furnace is 15 years or older. Systems in this age range are approaching the end of their reliable service life. Annual inspections become more important — and repair-vs.-replace conversations become more relevant.
How JDT Approaches Repair vs. Replacement
Every furnace call starts the same way: Joel looks at what's actually wrong before any replacement conversation happens. If the repair makes financial sense for your system's age and condition, we do the repair. If it doesn't — if the cost approaches what a new system would run, or if the system has a failed heat exchanger or chronic failure pattern — we tell you that clearly, with the numbers, so you can make the decision yourself.
Replacement gets recommended when the math supports it. Not before.
Furnace Brands We Service
We work on all major residential furnace brands, including:
- Carrier
- Lennox
- Trane
- Rheem
- Goodman
- York
- Bryant
- American Standard
If your furnace isn't on this list, call anyway — we service most residential systems regardless of manufacturer.

Common Furnace and Heating Questions
Who do I call if my heat goes out in Schaumburg or Streamwood?
Call JDT Heating and Cooling. We're owner-operated and answer emergency calls directly, 24 hours a day — including nights, weekends, and holidays. There's no answering service layer between you and the technician coming to your door.
Do you repair all furnace brands?
Yes. We service Carrier, Lennox, Trane, Rheem, Goodman, York, Bryant, American Standard, and most other residential furnace brands. If you're unsure whether we service your system, call and we'll confirm.
How do I know if my furnace needs repair or replacement?
The clearest factors are system age and the cost of the repair relative to replacement. A furnace under 15 years old facing a single-component failure is almost always worth repairing. A furnace over 15 years old with a failed heat exchanger or a history of repeated failures is often a replacement candidate. Joel will walk you through the numbers on-site before any recommendation is made.
What does furnace repair cost in the northwest suburbs?
Pricing depends on the repair, but JDT consistently runs well below what regional chains charge for the same work. You'll receive a clear quote before any work begins — no surprises on the invoice.
Do you offer 24/7 emergency furnace repair?
Yes. Heating emergencies don't follow business hours, and neither do we. Call the number on this page any time — Joel answers directly.
