Common Furnace Problems in Glen Ellyn Homes
About one in six Glen Ellyn homes was built before 1940. In those homes the furnace often replaced a boiler or gravity system, the ductwork was added in stages, and the furnace may still vent into a masonry chimney. Cold rooms, short cycling and overheating there are often airflow or venting problems, and we check them before quoting a part.
Many more Glen Ellyn homes were built from the 1960s through the 1980s. Those homes are typically on their second or third furnace, and inducer motors, pressure switches, control boards and condensate problems are the most common repairs we make. The photos on this page are from Lennox furnace installs our team recently finished in Glen Ellyn.
How a Glen Ellyn Furnace Repair Visit Works
We trace the heating sequence from the thermostat call through ignition, then check the safeties, electrical parts, venting, drainage and airflow. We measure before replacing anything, so you are not paying for parts the furnace did not need.
You get the cause and a flat-rate price before any work begins. Our trucks are stocked for the common furnace parts, so most furnaces are fixed on the first visit. We repair all major brands, including furnaces installed by other companies, and for most brands we handle the manufacturer parts warranty claim so you pay labor only.
Repair or Replace Your Glen Ellyn Furnace?
A well-maintained gas furnace lasts about 15 to 20 years in the Chicago area. A quick check is the $5,000 rule: multiply the furnace’s age by the repair price. Under $5,000, repairing usually makes sense. Over $5,000, it is worth getting a replacement price too.
A cracked heat exchanger is a safety issue at any age. If replacement makes more sense, the in-home estimate is free, Nicor Gas rebates apply to qualifying high-efficiency furnaces, and financing is available, including 0% APR on select Lennox systems during Lennox promotions.

Glen Ellyn Furnace Repair FAQs
How much does furnace repair cost in Glen Ellyn?
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 fast can you get to Glen Ellyn?
Our Streamwood shop is about 16 miles from Glen Ellyn, roughly 30 to 35 minutes via Gary Avenue in normal traffic. We answer 24/7 and offer same-day furnace repair when a truck is open.
Do you repair boilers and radiator heat?
Yes. We repair and replace gas boilers in older homes with radiators or baseboard heat, including circulator pumps, zone valves, expansion tanks and ignition controls.
Is it safe for my furnace to vent into an old chimney?
An older 80% furnace or boiler 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 equipment vents through its own plastic pipe instead.
Why does my furnace start, then shut off after a few minutes?
Short cycling is often a dirty flame sensor, a pressure switch fault from a blocked vent or condensate trap, or overheating from poor airflow. We test each one before quoting a repair.
Do you repair furnace brands other than Lennox?
Yes. Pure Comfort is a Lennox Premier Dealer, but we repair all major furnace brands in Glen Ellyn, including furnaces installed by other companies.
