Request Furnace Repair
Fire 'n' Ice Heating & Cooling, Inc. provides 24/7 furnace repair in Naperville, Illinois, as part of our full range of HVAC services in Naperville, for gas furnaces of every brand, from a family shop in neighboring Downers Grove that has been fixing heat since 1977. Our NATE certified technicians diagnose the fault, test for carbon monoxide on every call, quote the exact price before touching a part, and carry the ignitors, flame sensors, pressure switches, and motors that fail most often in Naperville homes, so most no-heat calls are fixed on the first visit. If the furnace is past saving, we say so and lay out furnace installation options with today's rebates. Call (630) 852-1300 any hour and a live person picks up.
Why Naperville Furnaces Fail, House by House
The first below-zero stretch of every Naperville winter fills our phone lines, and the calls follow the neighborhoods. In the 1960s and 70s ranches and split-levels near Downtown and Cress Creek, we see furnaces venting into original masonry chimneys and pulling return air through undersized ducts, which trips high-limit switches and short-cycles the burner until the house never quite warms up. In the 80s and 90s two-stories of Hobson West, Maplebrook, and Brookdale, most homes are on their second or third builder-grade furnace, and those units are now 18 to 25 years old: the classic failures are a dirty flame sensor that shuts the burner down after 5 seconds, a cracked hot-surface ignitor, a stuck pressure switch, or an inducer motor that whines and quits. South of 75th in Tall Grass, White Eagle, and Ashbury, the larger homes run 2 furnaces, and the one serving the upstairs works hardest against the attic and fails first.
Every furnace repair call in Naperville starts the same way: a combustion analysis and carbon monoxide test, because a furnace that keeps shutting itself off is often doing exactly what a safety control should. Once the fault is found, our trucks stock ignitors, flame sensors, pressure switches, limit switches, capacitors, blower and inducer motors, and control boards for Carrier, Bryant, Trane, Lennox, Rheem, Goodman, and Amana. If the heat exchanger is cracked or the unit is past 15 years with a major failure, you get an honest repair-versus-replace comparison on the spot, including current rebates, 0% financing for 5 years, and whether a hybrid heat pump makes sense under Naperville's own utility incentives.

Installed 3 Years Ago, Still Heating Like Day 1
A Carrier furnace we installed at a Naperville home 3 years ago, back on the schedule for its annual checkup. 3 Illinois winters, 0 repair calls. When a furnace is sized right, vented right, and maintained yearly, this is what its service history looks like, and it is the standard every repair we make is measured against.
Our crews add this winter's Naperville furnace repairs here as they wrap them, so check back.
How Fast We Reach a Naperville No-Heat Emergency
When it is 5 degrees outside and the house is dropping a degree an hour, the risk is not just discomfort; it is frozen pipes by morning. Our shop at 5240 Thatcher Rd in Downers Grove is one town over, and by I-88 or the Ogden Avenue and 75th Street corridors most Naperville furnace repair calls see a truck in roughly 20 to 30 minutes in normal conditions, with no-heat homes that have infants, seniors, or medical needs moved to the front of the line. The emergency line is answered by a live person 24 hours a day, we always have a technician on call, and the truck that arrives carries the parts that fix most Naperville furnaces on the spot. Reach a real human at (630) 852-1300, not a voicemail box.
Furnace and Heating Repair Services in Naperville
Emergency Furnace Repair
No heat, a furnace that starts and shuts off, a burner that will not light, a gas smell, or a carbon monoxide alarm. Same-day service across Naperville, 24 hours a day including holidays, with upfront pricing and no overtime surprises.
Diagnostics & Standard Repairs
Short cycling, weak airflow, a blower that runs but blows cool air, banging or whining noises, uneven rooms, or a gas bill that jumped. We find the actual cause, fix that, and tell you what to watch for so it does not come back in February.
Repair or Replace? We Tell You Straight
On furnaces past 15 years or facing a cracked heat exchanger, we compare the repair cost against a new system with today's rebates and financing. If repair wins, we repair. If not, our furnace installation team can usually have a new Carrier furnace in within days, and a hybrid heat pump is worth pricing under Naperville's utility incentives. Fall furnace maintenance keeps either one out of the repair queue, and our AC repair crew handles the other half of the year. See everything we do on our Naperville HVAC page.

The Furnace Repair Calls We Run in Naperville
A typical January week for our Naperville trucks looks like this:
- A no-heat call in a Maplebrook two-story at 6 AM, a flame sensor so coated it shut the burner down every 5 seconds, cleaned and back to heating before the kids left for school.
- A Cress Creek ranch from the 1970s short-cycling on its high-limit switch because the return was starved by a collapsed filter, corrected on the spot with a straight conversation about what the 25-year-old unit has left. Our guide to heating options for older Naperville homes covers what comes next.
- An upstairs furnace in Tall Grass whose inducer motor whined and quit during a cold snap, replaced from the truck the same visit so the second floor was warm by dinner.
- A Hobson West furnace that kept shutting off, where the combustion test found a cracked heat exchanger. We shut it down for safety, showed the homeowner the reading, and priced a replacement against the repair. Our breakdown of what drives furnace repair cost in Naperville explains how that decision gets made.
Different failures, same standard: carbon monoxide tested first, the price approved before work starts, shoe covers inside, the furnace run through a full cycle before we leave, and a plain-English rundown of what failed and why.

What Customers Say About Our Heating Work
Pulled straight from our 500+ Google, Facebook, and Yelp reviews:
"We knew our furnace and A/C were at least 25 years old and it was time for replacement. We got 3 quotes. Although Fire 'n' Ice was not the cheapest, the owner, Jim, took the time to inspect what we had, listen to what we wanted, and quoted a new heat pump system to meet our needs. The crew, Dan & Chris, did a great job installing the new system and provided insightful explanations of the system and components."
- Wesley C.
"Three years ago, we needed a new furnace and A/C. I was told that the installation was as important as the quality of the unit itself. I did some research and landed on Fire 'n' Ice. Their price was competitive, and their reviews were stellar. Their installation was flawless, and for the last three years, they have come for annual maintenance. Every tech that has come to our home has been on time, knowledgeable, and very clean."
- John B.
"The air conditioner went out one week ago today. I called Fire 'n' Ice, and Jim called me within 10 minutes and scheduled an appointment for the next day. Jim was open and honest and walked me through exactly what I needed. They were able to schedule a total HVAC replacement within 48 hours. When the techs arrived, they were amazing communicators, professional, and kept us updated throughout the day. The system is running great, and during a time of non-stop inflation and companies taking advantage, Fire 'n' Ice gave me a great value for the product."
- Matt L.
Why Naperville Calls Us When the Heat Goes Out
A furnace repair is a trust decision made in a cold house, usually at night, which is exactly when a homeowner is easiest to scare into a replacement they do not need. Our answer to that is 49+ years in the same community, 9 Carrier President's Awards as a Carrier Factory Authorized Dealer, NATE certified and background-checked technicians, a carbon monoxide test on every call, and a price you approve in writing before the repair starts. We do not sell furnaces to people who need a $150 flame sensor, and we do not sell $150 parts to people whose heat exchanger is cracked. Every repair is run through a full heating cycle before we leave, and if a part we installed fails, we come back and make it right. That is why more than 500 of your neighbors rate us 4.9 stars, and why Naperville customers call us back winter after winter for everything heating and cooling in Naperville.
Naperville Furnace Repair Questions, Answered
Most furnace repairs in Naperville land between $150 and $600, depending on the failed part. Flame sensors, ignitors, and thermostats sit at the low end; pressure switches and capacitors in the middle; blower motors, inducer motors, and control boards at the top. A cracked heat exchanger is the exception and usually triggers a repair-versus-replace conversation. You approve the exact price before any work begins.
Most calls see a technician in about 20 to 30 minutes from our Downers Grove shop in normal conditions. During cold snaps we prioritize no-heat homes with infants, seniors, or medical needs, and emergency dispatch runs 24/7, including weekends and holidays.
Yes. A live person answers (630) 852-1300 at any hour, and we always have a technician on call. After business hours your call is picked up by our answering team, who reaches the on-call tech right away. You will never be sent to a voicemail box or told to call back in the morning.
The usual causes are a dirty flame sensor shutting the burner off after a few seconds, a failed ignitor, a tripped high-limit switch from restricted airflow, or a thermostat set to fan-only. If the furnace starts, runs briefly, and shuts down repeatedly, turn it off at the switch and call us; a safety control is doing its job and running it on the cycle can damage the control board.
A good rule: under 12 years old with a minor part, repair it. Over 15 years old, or facing a cracked heat exchanger or a repair over a third of the cost of a new furnace, the money is usually better put toward a new system, especially with current rebates and 0% financing. We show you both numbers and let you choose.
All major brands, including Carrier, Bryant, Trane, Lennox, Rheem, Ruud, Goodman, Amana, York, and American Standard. As a Carrier Factory Authorized Dealer we carry the deepest Carrier parts stock, but our technicians are trained across every residential gas furnace common in Naperville, including high-efficiency condensing models.
Not without a diagnosis. Repeated shutdowns usually mean a safety control is tripping, and the cause can range from a harmless dirty sensor to a cracked heat exchanger that leaks carbon monoxide into the house. If a CO alarm sounds, leave the house and call from outside. Otherwise turn the furnace off and call us; every furnace repair visit includes a combustion and carbon monoxide test.
A fall tune-up catches dirty flame sensors, weak ignitors, cracked heat exchangers, and restricted airflow before the first cold snap, which is when most Naperville furnaces fail. Our furnace maintenance visit covers all of it, keeps your manufacturer warranty valid, and includes a carbon monoxide test. For every other service we offer in town, see our Naperville HVAC page.
