What Does Furnace Replacement Cost for Most Homeowners?

Furnace replacement cost for most homeowners is set after an on-site evaluation because price varies by furnace size, efficiency, and any home updates needed. The largest swing comes from choosing the right capacity and whether venting, condensate, duct, or gas/electric changes are required. From the field, high-efficiency swaps often need new PVC venting and drains, while correct sizing prevents paying for oversize equipment. Our licensed team frequently replaces furnaces in the Montville area with upfront, flat-rate pricing, written estimates, warranty-backed materials, and optional financing.

Key price drivers:

• Home heating load (BTUs) and feature set
• Efficiency level and venting/condensate parts
• Fuel type and any electrical or gas upgrades
• Duct fixes, zoning, or permit/code work
