Choosing a New Furnace for a Northlake Home
The median Northlake home was built in 1957, and many early houses were finished by their owners, so ducts, return locations and wiring can be different from house to house. We inspect before quoting a furnace replacement so there are no surprises. Compact postwar basements leave tight mechanical space, and many older furnaces vent into a chimney shared with the water heater. In low areas near Addison Creek, we also check whether past flooding damaged the ducts or the base the furnace sits on. In one recent Northlake home, we fit a new Lennox furnace, new metal venting and a Honeywell Home media air cleaner into a narrow utility closet.
Furnace Installation in Northlake: How It Works
It starts with a free visit to your Northlake 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 Northlake 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 Northlake furnace is younger or the repair is small, a repair may be the better value, and our furnace repair team can diagnose it for $75.

Northlake Furnace Replacement FAQs
How much does a new furnace cost in Northlake?
As of October 2026, a new furnace from Pure Comfort costs $3,000 to $9,500 installed in Northlake. Ductwork in owner-finished postwar homes, chimney venting for older basement furnaces and past flood damage drive most of the price in Northlake. 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 Northlake?

Do I need a permit to replace a furnace in Northlake?
Permit needs for a furnace replacement in Northlake depend on the equipment and project scope. Where a permit is required, we confirm the City of Northlake’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 Northlake?
A 96% to 97% furnace is usually the better long-term choice in Northlake, but it vents with PVC instead of the chimney. Where the furnace and water heater share a chimney, we price the PVC venting and water heater liner together so you can compare.
How long does a furnace replacement take?
Most furnace replacements in Northlake 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 Northlake?
Yes. Pure Comfort is based in Streamwood, about 32 minutes from Northlake, and installs furnaces across 60164. 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 Northlake, we check the furnace and give you both prices so you can decide.
