How Much Does a New Furnace Cost in 2026?
A new furnace costs $3,500-$8,000 installed in central Illinois, with most homeowners paying around $5,000-$6,000 for a mid-range, high-efficiency unit. The price depends on three things: the efficiency rating (AFUE), the size of the unit (measured in BTUs), and the complexity of your installation. Here's a full breakdown so you know exactly what you're paying for.
What Affects the Price of a New Furnace?
- Efficiency (AFUE): An 80% AFUE furnace costs $3,500-$5,000 installed. A 95-98% AFUE high-efficiency unit costs $5,000-$8,000 but cuts your heating bills 20-30%.
- Size: A furnace that's too small won't keep up. Too big and it short-cycles, wasting energy. Proper sizing requires a load calculation, not guesswork.
- Installation complexity: Ductwork modifications, gas line upgrades, or switching from electric to gas add $500-$2,000.
- Brand: Premium brands cost more but often come with longer warranties and better parts availability.
Should You Choose High-Efficiency or Standard?
In central Illinois, a high-efficiency furnace (95%+ AFUE) usually pays for itself within 5-7 years through lower gas bills. If you plan to stay in your home, the math favors high-efficiency every time. If you're selling soon, a standard 80% unit saves upfront. The U.S. Department of Energy confirms that upgrading from a 60% to a 95% furnace can cut heating costs nearly in half.
How Do You Know If You're Getting a Fair Price?
Get at least two quotes. A reputable company will do a load calculation, not just match your old unit's size. They should explain what's included: permit, thermostat, ductwork connections, old unit disposal, and warranty terms. Watch out for "too good to be true" prices that exclude installation labor or necessary modifications. Not sure if you need a new furnace? Use the 50% rule to decide.
