Choosing a New Furnace for a Glen Ellyn Home
Roughly one in six Glen Ellyn homes predates 1940, and many Victorians, Prairie-style homes and early Colonials near downtown and Lake Ellyn have a furnace that replaced a boiler or gravity system, with ductwork added in stages. Choosing a new furnace for these homes starts with the chimney: we check the liner and draft, then decide whether to stay with chimney venting or run new PVC. A large share of the village was built from the 1960s through the 1980s, and those two-story Colonials and split-levels are often on a second or third furnace. In them, we size by load calculation and look at return air, and a variable-speed furnace can help the upstairs rooms that original ducts underserve.
Furnace Installation in Glen Ellyn: How It Works
It starts with a free visit to your Glen Ellyn 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 Glen Ellyn 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 Glen Ellyn furnace is younger or the repair is small, a repair may be the better value, and our Glen Ellyn furnace repair team can diagnose it for $75.

Do I need a permit to replace a furnace in Glen Ellyn?
Permit requirements for a furnace replacement in Glen Ellyn depend on the equipment and project scope. Where a permit is required, we confirm the Village of Glen Ellyn’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 Glen Ellyn?
In Glen Ellyn’s 1960s to 1980s homes, a 96% furnace with PVC venting is the usual choice. In pre-1940 homes, an 80% furnace can stay in a lined chimney that drafts properly, or a 96% model can vent through new PVC.
How long does a furnace replacement take?
Most furnace replacements in Glen Ellyn 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 Glen Ellyn?
Yes. Pure Comfort is based in Streamwood, about 30 minutes from Glen Ellyn, and installs furnaces across 60137. 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 Glen Ellyn, we check the furnace and give you both prices so you can decide.
