Furnace Not Working? Common Furnace Problems in Deerfield Homes
About 43 percent of Deerfield homes were built in the 1950s and 1960s, and many have added a family room, primary suite or second story onto the original ductwork. A furnace pushing air into an addition the ducts were never sized for often overheats and shuts off on its limit switch. Older homes may share a chimney between the furnace and water heater, and high-efficiency furnaces from the 1990s and 2000s are at the age when inducers, pressure switches and control boards fail. Frozen condensate lines are common no-heat calls in January.
How a Deerfield Furnace Repair Visit Works
In Deerfield, we often find the furnace is fine but the addition it feeds is not getting enough air, so we check airflow to added rooms along with the furnace. Venting gets a close look too, since many older homes share a chimney with the water heater. From there, our method holds steady. We follow the heating sequence from the thermostat call through ignition. Then we check the safeties, electrical parts, venting, drainage and airflow. Parts are measured before anything is replaced. 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 from other installers. For most brands we handle the manufacturer parts warranty claim, so you pay labor only.
Repair or Replace Your Deerfield Furnace?
Many Deerfield homes are on their second or third furnace, often feeding additions the original ducts were never sized for. A well-maintained gas furnace lasts about 15 to 20 years in the Chicago area. Apply the $5,000 rule: multiply the furnace’s age by the repair price. Under $5,000, repair usually makes sense. Over $5,000, get a replacement price too. A cracked heat exchanger is a safety issue at any age. Replacement estimates are free. North Shore Gas rebates apply to qualifying high-efficiency furnaces, and financing is available, including 0% APR on select Lennox systems during Lennox promotions.

Deerfield Furnace Repair Cost and Timing
In Deerfield, most furnace repairs cost $100 to $700, with about $300 the average. Igniters, flame sensors and pressure switches sit at the low end. Inducer motors, control boards and blower motors cost more. If an addition is starving the furnace for airflow, we price the duct fix alongside the repair. You approve a written, flat-rate price before work starts.

Deerfield Furnace Repair FAQs
How much does furnace repair cost in Deerfield?
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 Deerfield?
Our Streamwood shop is about 50 minutes from Deerfield in normal traffic. We answer 24/7 and offer same-day furnace repair when a truck is open.
Why is our Deerfield addition always colder than the rest of the house?
Additions are often tied into ductwork sized for the original house, so they get too little warm air. A bigger furnace rarely fixes it. We check airflow, returns and the furnace, then tell you whether balancing, a duct change or a separate system will help.
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.
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 Deerfield, 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.
