What Impacts Your Furnace Replacement Cost
AFUE efficiency rating
+25–50%An 80% AFUE furnace is the budget baseline; 95–98% AFUE condensing units cost more but cut fuel bills 15–20% and qualify for tax credits.
Fuel type
VariableNatural gas is cheapest to operate; propane and oil furnaces cost more upfront for storage and delivery infrastructure.
BTU sizing
+15–30%Each 20,000 BTU step up adds equipment cost. Oversizing causes short-cycling and reduces lifespan.
Venting changes
+$400–$1,200Switching to a 95%+ condensing furnace requires PVC sidewall venting and a condensate drain — not always trivial in older homes.
Ductwork modifications
+$1,000–$4,000If your old ductwork was undersized for the new furnace, expect rebalancing or trunk line modifications.

15 yrs
…AND repair quote exceeds

of full replacement

$2,025

Frequently Asked Questions
Is this actually worth it?
A furnace replacement in 2026 typically returns 60–80% of project cost at resale within the first 5 years, and avoids 2–4× higher emergency-replacement pricing. Owners with a documented furnace timeline negotiate ~$3,800 better at sale on average.
Run the ROI mathShould you replace now or wait?
Break-even rule: if annual repair cost exceeds 8% of replacement cost — or the unit is past 75% of expected life — replacement wins. Below that threshold, deferring 18–36 months and funding a sinking fund usually beats panic timing by $1,800–$5,400.
Run the break-even mathHow this impacts your home value
A failing or end-of-life furnace typically triggers a $4,000–$12,000 appraiser adjustment in Ohio and shows up in inspection reports as a buyer-negotiation lever. A documented replacement plan inside the last 3 years of life preserves listing price.
