Choosing a New Furnace for a Wheaton Home
Nearly half of Wheaton’s homes were built in the 1970s and 1980s, mostly two-story colonials, split-levels and raised ranches now on their second or third furnace. Many original systems were oversized, and later replacements often copied that size. We run a load calculation instead, because a right-sized furnace runs longer, steadier cycles and is easier on the original ductwork. These homes often have limited return air to upstairs bedrooms, so a variable-speed blower and return improvements usually do more than extra BTUs. Older homes near downtown and Wheaton College may still have chimney venting or a boiler, which changes the plan. Furnaces from the 2000s are reaching the age when major parts fail, so many owners are weighing replacement now.
Furnace Installation in Wheaton: How It Works
It starts with a free visit to your Wheaton home. We measure the house and ductwork, check the venting and gas supply and run a load calculation, then give you written Good, Better and Best Lennox options with rebates and financing laid out. On install day, our own crew removes the old furnace, sets the new one, connects venting, gas, condensate and controls, and tests combustion, temperature rise and airflow before we leave. We register the warranty and walk you through the new thermostat settings.
Repair or Replace Your Wheaton Furnace?
A gas furnace usually lasts 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. If the result is over $5,000, replacement usually makes more sense. If your Wheaton furnace is younger or the repair is small, a repair may be the better value, and our Wheaton furnace repair team can diagnose it for $75.

Wheaton Furnace Replacement FAQs
How much does a new furnace cost in Wheaton?
As of October 2026, a new furnace from Pure Comfort costs $3,000 to $9,500 installed in Wheaton. Right-sizing oversized originals, return air for upstairs bedrooms and venting changes in older downtown homes drive most furnace prices here. Replacing the furnace and air conditioner together costs $8,000 to $19,000, and Nicor Gas rebates of $150 to $225 apply to qualifying 95% and 97% AFUE furnaces.
How do I get a free furnace estimate or quote in Wheaton?
Call (708) 515-4822 or book online. We visit your Wheaton home, measure the house and ductwork, run a load calculation and give you written Good, Better and Best options with rebates and financing. The estimate is free, and there is no pressure to decide on the spot.
Do I need a permit to replace a furnace in Wheaton?
Where a permit is required, we confirm the City of Wheaton’s current requirements and pull the permit, or help you file it in towns where the homeowner applies, then schedule any required inspection.
Should I choose an 80% or a high-efficiency 96% furnace in Wheaton?
Most of Wheaton’s 1970s and 1980s homes can move to a 96% furnace with PVC venting. Older homes near downtown and Wheaton College often vent through a chimney shared with the water heater, so we price the venting for both before you choose 80% or 96%.
How long does a furnace replacement take?
Most furnace replacements in Wheaton take one day. Jobs that add return air, new venting or zoning can take a second day. If you are without heat, tell us when you call so we can schedule the install as soon as the equipment is available.
Is there a furnace replacement company near me in Wheaton?
Yes. Pure Comfort is based in Streamwood, about 30 minutes from Wheaton, and installs furnaces across 60187 and 60189. We are a Lennox Premier Dealer with NATE-certified technicians, and our own crews do every install.
Is it worth replacing a 20- or 30-year-old furnace?
Usually, yes. Most furnaces last about 15 to 20 years in Chicago-area winters. A 20- to 30-year-old furnace is often far less efficient than a new high-efficiency model, parts get harder to find, and heat exchanger problems become more likely. If yours is safe and the repair is small, fixing it can still make sense. In Wheaton, we check the furnace and give you both prices so you can decide.
