Furnace Not Working? Common Furnace Problems in Elgin Homes
Elgin has some of the oldest housing in our service area. Many homes in the neighborhoods around downtown were built before 1940 and were converted from boiler or gravity heat, so ductwork can be undersized, patched together or partly hidden in walls. When a furnace in one of those homes overheats, short cycles or cannot keep the far rooms warm, the cause is often airflow or venting rather than a failed part.
Older furnaces in Elgin may still vent into a masonry chimney, and a deteriorating chimney liner can cause venting problems that we look for whenever we service an older furnace. In the newer homes on the far west side, high-efficiency furnaces are the norm, and flame sensors, igniters, pressure switches and condensate drains cause most no-heat calls. The photos on this page are from furnace installs our team recently finished in Elgin.
What to Expect During a Furnace Repair Visit in Elgin
An Elgin furnace call often starts with a different question: is it the furnace, or the house around it? We begin at the thermostat and follow the heating sequence through ignition. Then we check the safeties, electrical parts, venting, drainage and airflow. In the older homes near downtown, airflow and venting get extra attention, because ductwork left over from boiler or gravity heat and masonry chimney venting can cause trouble that looks like a bad part. Out on the west side, condensate drains on high-efficiency furnaces get a close look.
We measure before we replace anything. You hear the cause and a flat-rate price before work begins. Our trucks carry the common furnace parts, so most furnaces are fixed on the first visit. We repair all major brands, including furnaces another company installed. For most brands, we handle the manufacturer parts warranty claim and you pay labor only.
Repair or Replace Your Elgin Furnace?
Elgin furnaces come in every age. Many homes around downtown were built before 1940 and converted from boiler or gravity heat, while the subdivisions west of Randall Road run mostly on high-efficiency furnaces. In the Chicago area, a well-maintained gas furnace lasts about 15 to 20 years. To weigh a repair, try the $5,000 rule. Multiply the furnace’s age by the repair price.
Under $5,000, repairing usually makes sense. Over $5,000, get a replacement price as well. One exception: a cracked heat exchanger is a safety issue at any age. If replacing is the better call, we come out for a free in-home estimate. Nicor Gas rebates apply to qualifying high-efficiency furnaces. Financing is available too, including 0% APR on select Lennox systems during Lennox promotions.

Elgin Furnace Repair Cost and Timing
Expect most Elgin furnace repairs to land between $100 and $700, with about $300 the average. On the newer west side homes, the usual fixes are flame sensors, igniters and pressure switches, which sit at the low end. Inducer motors, control boards and blower motors cost more. In older homes near downtown, a tight basement or venting work can add time, and that time is built into the written flat-rate price you approve before we start.

We installed a Lennox full system. El297v furnace, cased evaporator coil and 14 seer ac unit. New bypass humidifier. Reconnected nest thermostat. Larger filter rack and return air base.
“I used this guys again Prices didn’t change since 2022 on diagnostics etc. I had a new problem with furnace not working properly, arrived, found the problem, gave an advise what to do by myself so I may save some $$$, after investigation they found a bit worse problem with my furnace which required couple thousand dollars repair so since my furnace was 20 years old I decided to change it using this company. In 1-2 days I received a quote from them. Also they had a special finance option 18-25 months at 0% if paid in this period. Got approved, made an appointment with them for Saturday by the way. They came at 8 a.m. job done around 4 p.m. they did their best to work clean which it is a big plus, it passed almost 2 weeks everything works fine, no errors or problems with the job they have do”

Elgin Furnace Repair FAQs
How much does furnace repair cost in Elgin?
The diagnostic is $75, or $99 evenings, weekends and holidays. Most furnace repairs cost $100 to $700, and about $300 is typical. You approve a flat-rate price before any work starts.
How long does it take you to reach Elgin?
Our Streamwood shop is about 6 miles from Elgin, roughly 15 to 20 minutes via Irving Park Road. Homes on the far west side take a little longer. We answer 24/7 and offer same-day repair when a truck is open.
My older Elgin home was converted from a boiler. Can a furnace still heat it well?
Yes, but the ductwork matters. Converted homes often have small or added-on ducts and too few returns. We measure airflow and temperature rise, and we will tell you if duct changes would fix cold rooms better than a furnace repair.
Is it safe for my furnace to vent into an old chimney?
An older 80% furnace can vent into a masonry chimney if the chimney is lined and drafting properly. We check draft and look for signs of a deteriorating liner. High-efficiency furnaces vent through their own plastic pipe instead.
Do you repair high-efficiency furnaces in newer Elgin homes?
Yes. Most no-heat calls on newer high-efficiency furnaces come from a dirty flame sensor, a failed igniter, a pressure switch fault or a clogged condensate trap, and our trucks carry those parts.
Do you repair furnace brands other than Lennox?
Yes. Pure Comfort is a Lennox Premier Dealer, but we repair all major furnace brands in Elgin, including furnaces installed by other companies.
What is the $5,000 rule for furnace repair?
Multiply the age of the furnace by the repair price. If the total is more than $5,000, replacing usually makes more sense than repairing. For example, a $350 repair on a 16-year-old furnace comes to $5,600. It is a rule of thumb, not a hard cutoff, so we give you both options in writing.
My furnace is not working and I have no heat. What should I check first?
Make sure the thermostat is set to heat, the furnace switch is on, the breaker has not tripped and the filter is not clogged. If it still will not run, call (708) 515-4822. We answer 24/7, and no-heat calls in Elgin are often handled the same day.
