Choosing a New Furnace for a Addison Home
Most Addison homes date from the 1950s through the 1970s, so the furnace in a typical ranch or split-level is the second or third one the house has had. Many replacements from the 2000s are now near the end of their service life. The original ductwork in these homes was sized for smaller equipment, so we run a load calculation instead of matching the old nameplate, and we look at return air before picking a blower. A right-sized furnace with a variable-speed blower runs longer, quieter cycles through tight ducts. Where the furnace still shares a chimney with the water heater, the venting plan is part of the quote, because moving the furnace to PVC can leave the water heater alone in a chimney too big for it.
Furnace Installation in Addison: How It Works
It starts with a free visit to your Addison 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 Addison 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 Addison furnace is younger or the repair is small, a repair may be the better value, and our Addison furnace repair team can diagnose it for $75.

Addison Furnace Replacement FAQs
How much does a new furnace cost in Addison?
As of October 2026, a new furnace from Pure Comfort costs $3,000 to $9,500 installed in Addison. Return air upgrades for undersized original ducts and venting changes in chimney-vented ranches drive most of the furnace price in Addison. 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 Addison?

Do I need a permit to replace a furnace in Addison?
Where a permit is required, we confirm the Village of Addison’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 Addison?
Many Addison homes still vent the furnace through a chimney shared with the water heater. A 96% furnace vents through PVC, so we plan for a liner or water heater change at the same time. Where that is not practical, an 80% furnace can still make sense.
How long does a furnace replacement take?
Most furnace replacements in Addison 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 Addison?
Yes. Pure Comfort is based in Streamwood, about 30 minutes from Addison, and installs furnaces across 60101. 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 Addison, we check the furnace and give you both prices so you can decide.
