Furnace Replacement Cost in Kansas

A 80,000 BTU gas furnace installed in Central Kansas runs $4,500–$9,800 in 2026, depending on efficiency (80% vs. 95%+ AFUE), single-stage vs. two-stage, and how much venting and electrical work the install needs.

Standard tiers

• 80% AFUE single-stage: $4,500-$6,000 — cheapest upfront, most gas burned.
• 95% AFUE single-stage: $5,500-$7,500 — sweet spot for most Kansas homes.
• 95%+ AFUE two-stage: $6,800-$8,900 — quieter, better temperature stability.
• 95%+ AFUE modulating variable-speed: $8,000-$9,800 — premium comfort, longest payback.

What's included

• New furnace with matched blower and heat exchanger.
• New gas line connections and shutoff.
• New venting (95%+ AFUE requires PVC intake + exhaust rerouting; 80% often reuses metal flue).
• New condensate drain and trap (95%+ AFUE).
• Combustion analyzer commissioning.
• Warranty registration.

Cost drivers unique to Kansas

Older Salina homes with cast-iron flue chases often need chimney lining ($350-800) when we swap in high-efficiency equipment because the old chimney is now oversized for the smaller flue volume. Homes with attic-mount furnaces cost 15-25% more due to access.

Key takeaway. For most Salina-area homes, a 95% AFUE single-stage furnace at $5,500-$7,500 is the pragmatic sweet spot — enough efficiency for real savings, not enough premium to stretch payback.
