Furnace Not Working? Common Heating Problems in Buffalo Grove Homes
Many Buffalo Grove furnaces fall into two groups: closet furnaces in slab ranches, where tight return air and heat buildup cause overheating and short cycling, and basement furnaces in two-story homes that struggle to push heat to the second floor. The repairs we see most are igniters, flame sensors, pressure switches, inducer motors and control boards, and we check airflow and venting on every visit.
What to Expect From a Buffalo Grove Heating Repair Call
In Buffalo Grove, we start by finding out where the furnace sits: a slab-ranch closet, a basement or a townhome utility room. That shapes what we check first. The visit starts with the thermostat call, and we follow it step by step through ignition. Then we test the safeties, electrical parts, venting, drainage and airflow. A short-cycling furnace often points to undersized ducts or a restricted return, so we measure before blaming a part. Where the furnace and water heater share a chimney, draft gets checked on every visit. Once we know the cause, you get a flat-rate price before work begins. Trucks carry common furnace parts, which means most furnaces are fixed on the first visit. We repair all major brands, even furnaces another company installed. For most brands we handle the manufacturer parts warranty claim, and you pay labor only.
Deciding Between Furnace Repair and Replacement in Buffalo Grove
Many Buffalo Grove homes from the 1970s and 1980s are on their second furnace, and the early slab ranches may be on their third. Around Chicago, a well-maintained gas furnace lasts about 15 to 20 years. To decide on a repair, multiply the furnace’s age by the repair price. That is the $5,000 rule. Below $5,000, repair is usually the better call. Above it, get a replacement price too before you decide. Any furnace with a cracked heat exchanger is a safety issue, no matter its age. If you want to compare, the in-home estimate is free. Repair usually wins until a furnace nears the end of its 15 to 20 year life. The $5,000 rule helps: age times repair cost under $5,000 means fix it; over $5,000, look at replacing it too. Any cracked heat exchanger is a safety replacement. If you want to compare, the replacement estimate is free, and Nicor Gas rebates and 0% APR financing on select Lennox systems during promotions can narrow the gap.

What Buffalo Grove Homeowners Ask About Furnace Repair
What do common furnace parts cost to replace in Buffalo Grove?
Flame sensors $245 to $275, igniters $245 to $305, pressure switches $250 to $355, control boards $475 to $1,200, gas valves $505 to $1,120, inducer motors $400 to $1,095 and blower motors $830 to $2,220, all flat-rate with parts and labor. The $75 diagnostic is waived with the repair, and maintenance plan members save 10 to 15%.
What if my furnace stops at night in Buffalo Grove?
Call us. Phones are answered 24/7, and evening appointments run until 8 pm. After that, we book you for the first open slot the next day and call sooner if one opens. Buffalo Grove is about 30 minutes from our shop.
What causes a furnace to short cycle?
A dirty flame sensor, a blocked vent or condensate trap tripping the pressure switch, or overheating from restricted airflow. On high-efficiency furnaces, snow over the exterior vent can do it too. We test before replacing anything.
What happens to my chimney when I get a high-efficiency furnace?
The furnace vents out the side through plastic pipe, so the water heater may be left alone in the chimney. If the chimney is too large for it, the water heater can draft poorly, so we check it.
Should I repair a 20-year-old furnace?
Use 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 usually means replacement.
Do you repair furnace brands other than Lennox?
Yes. Pure Comfort is a Lennox Premier Dealer, but we repair all major furnace brands in Buffalo Grove, including furnaces installed by other companies.
