Picking the Right New Furnace for Your Buffalo Grove Home
Buffalo Grove has two very different kinds of furnace installs. The original slab ranches from the late 1950s and 1960s often keep the furnace in a first-floor closet, where a new unit has to fit the space and the return air is usually tight. The two-story homes and townhomes in subdivisions like Strathmore and the Woodlands of Fiore mostly have basement furnaces feeding long runs to the second floor, where a variable-speed blower helps even out the upstairs. We size every furnace with a load calculation, and where an older furnace shares a chimney with the water heater, moving to a 96% model means planning PVC venting and checking that the water heater still drafts.
Step by Step: Furnace Replacement in Buffalo Grove
The furnace estimate is free and done at your Buffalo Grove home: measurements, a duct and venting check and a load calculation. Then you get written options with Nicor Gas rebates and financing. Most furnace replacements take a day. We remove the old unit, install the new furnace, connect gas and venting, and test combustion, temperature rise and static pressure before we leave.
Furnace Repair vs. Replacement in Buffalo Grove
Most gas furnaces here last 15 to 20 years. Multiply your furnace’s age by the repair quote: over $5,000 usually means a new furnace is the better buy, under $5,000 usually means repair it. A cracked heat exchanger means replacement at any age.

Closet installs in slab ranches, venting changes and upstairs airflow in two-story homes drive most of the price.

Common Buffalo Grove Furnace Replacement Questions
How much should I budget for a new furnace in Buffalo Grove?
Budget $3,000 to $9,500 for a new furnace, or $8,000 to $19,000 with a new AC. Financing, including 0% APR on select Lennox systems during promotions, can spread the cost. Closet installs in slab ranches, venting changes and upstairs airflow in two-story homes drive most of the price.
How do I get a free furnace estimate or quote in Buffalo Grove?
Call (708) 515-4822 or book online. We visit your Buffalo Grove 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.
Is the permit included in your furnace quote?
Where Buffalo Grove requires one, the permit and inspection scheduling are part of the job. We confirm the requirements before install day.
Should I choose an 80% or a high-efficiency 96% furnace in Buffalo Grove?
Most Buffalo Grove homes can take a 96% furnace vented through PVC. In closet installs, we check that the new furnace and its venting fit the space, and if the old furnace shares a chimney with the water heater, we plan the venting so the water heater still drafts properly.
How long does it take to install a new furnace in Buffalo Grove?
One day for most homes. Adding return air, new venting or zoning can add a second day.
Do you use subcontractors for furnace installs in Buffalo Grove?
No. Our own NATE-certified crews install every system, and we are about 30 minutes from Buffalo Grove.
How much can a new furnace save over a 20-year-old one?
Older 60% to 80% furnaces waste far more gas than a 96% model. Savings depend on your home, so we compare options in writing, along with the cost of keeping the old one running.
