What drives the price
- Efficiency (AFUE rating) — the biggest driver.
- Furnace size (BTU) for your home
- Gas vs electric
- Ductwork or venting modifications
- Removal of the old unit
How to save on furnace replacement
- In mild climates, an 80% AFUE furnace is plenty — the high-efficiency premium pays back slowly where winters are short.
- Right-size it; an oversized furnace short-cycles, costing more upfront and in fuel.
- Replace in the off-season (spring/summer) for better pricing.
- Bundle with AC if both are aging — a combined install is cheaper than two trips.
How to get an accurate furnace replacement quote (and avoid overpaying)
National averages tell you the ballpark; only a quote tells you your number. Here's how to get a fair one:
- Get at least 3 itemized quotes. For the same furnace replacement, bids routinely vary 20–40%. Comparing line items (not just the total) is the fastest way to spot padding.
- Check license & insurance. Ask for the contractor's license number and proof of liability + workers' comp. Unlicensed/uninsured bids are cheaper for a reason.
- Beware the extremes. A bid far below the others usually means a missing scope item or a bait price; a high-pressure "today only" quote is a classic overpay trap.
- Get it in writing. The quote should list materials, labor, what's included (removal, permits, cleanup), the timeline, and the warranty.
- Confirm what's not included. Removal/disposal, permits, and code upgrades are the line items that turn a "cheap" bid into the expensive one.
