How much does a new furnace cost for a 2000 square-foot house?

Summers Plumbing Heating & Cooling prices a new furnace for a 2,000 sq ft home only after an in-home evaluation, because final cost depends on system sizing, efficiency, and installation conditions. The biggest driver is matching the furnace size and efficiency to the home’s actual heat load, not square footage alone. Expect a clear, written quote that includes equipment selection, old-unit removal, startup testing, and a post-install walkthrough, backed by written equipment and labor warranties. Our team regularly installs and replaces furnaces across the Indianapolis area.

Key factors that set the price:

• Fuel type and efficiency rating (standard vs high-efficiency)
• Installation scope (ductwork changes, venting, gas/electrical updates)
• Home characteristics (insulation, windows, layout affecting heat load)
• Add-ons or controls (humidifier, air quality, smart thermostat)
• Brand and warranty package

Summers also offers flexible financing options with low monthly payments for those who qualify.
