National Baseline & Scope Drivers
Replacing a gas or propane furnace while keeping the existing air conditioning system. National planning range for this job sits between $2,500 and $8,000.
Key Price Drivers for Furnace Replacement
- Efficiency rating (AFUE): An 80% AFUE furnace is the minimum and cheapest. A 95 to 98% condensing furnace costs $1,000 to $2,000 more but saves $200 to $400 per year in fuel.
- Capacity (BTU input): Oversizing is as harmful as undersizing. A Manual J calculation determines the correct input rating. Most homes need 60,000 to 100,000 BTU.
- Venting change: High-efficiency condensing furnaces require PVC venting and a condensate drain. Converting from metal B-vent to PVC adds $300 to $800.
- Gas line and code upgrades: A new gas shutoff, sediment trap, and combustion air requirements may be triggered by the replacement.
- Duct connection and plenum: A deteriorated plenum or transition at the furnace connection may need replacement during the swap.
