IN THIS GUIDE ▾
This is a contractor pricing guide for furnace replacement. It covers what customers expect to pay in 2026 ($2,000-$12,000, typically $5,000), what a changeout costs you in equipment and labor by fuel and AFUE, and the margin that leaves. Use it to check your price book and to build good-better-best options that move customers up from the entry price.
Furnace Replacement pricing by size and type.
Installed prices for an 80,000 BTU furnace swapped in the same spot at national average prices. Efficiency (AFUE) and staging drive most of the spread; new PVC venting or a relocation adds to any row.
The Equipment column is roughly what the customer sees on the equipment line; the Installation column is labor, materials and permits. Your cost sits below both. The gap between your cost and the Total column is the margin you have to work with.
Turn the numbers above into a quote you can send from the driveway.
Load your equipment cost, labor hours and rate, apply your markup, and EstimateKit produces the itemized PDF with good-better-best options. Not sure what margin to target? Run the job through the markup calculator first.
What moves the furnace replacement price and your cost.
Each factor below changes what you can charge, what the job costs you, or both. Use the impact figures to explain price differences to customers and to decide which upgrades belong in your better and best options.
Annual Fuel Utilization Efficiency measures how much fuel converts to heat. A 95% AFUE furnace converts 95 cents of every fuel dollar into heat.
Single-stage runs at full blast, two-stage offers high/low settings, and modulating adjusts output in 1% increments for precise comfort.
Natural gas furnaces are most common. Propane, oil, and electric options available but may cost more to install or operate depending on local fuel prices.
Heating capacity is measured in BTUs. Larger homes in cold climates need higher BTU furnaces, which cost proportionally more.
High-efficiency furnaces require PVC venting instead of metal chimneys. Converting venting adds to installation complexity and cost.
Premium brands like Carrier, Lennox, and Trane cost more but often offer better warranties and parts availability.
What furnace replacement sells for by region.
Labor rates, permitting and cost of living move the going rate. Price against your local market, not the national average.
Cold climates require larger, more powerful furnaces and installation is complicated by older homes and strict codes.

Add-on lines to include in the quote.
These are the items that get forgotten on a rushed quote and then eaten as unbilled cost. Put them on the estimate as separate lines so the customer sees them and you get paid for them.
How to price furnace replacement accurately.
Customers compare 3-5 quotes on a job this size. The ones that win are rarely the cheapest; they are the clearest. Build your furnace replacement price from cost up, then present it so the customer can see what they are paying for:
Set your markup percentages once, pick the equipment and hours, and the itemized quote is ready to send in 10-15 minutes, with customer records and scheduling in the same place.

When a customer asks why they should not do it themselves or take the cheapest quote, these are the points to put in your proposal.
Payment and financing options to offer.
Offering a financing path raises close rates on larger tickets. These are the ways customers typically pay for furnace replacement; put the ones you support on the quote.
Straight answers you can reuse on the phone, in the proposal, or on your own website.
Most furnaces last 15-20 years with proper maintenance. Signs of replacement include frequent repairs, uneven heating, increased energy bills, and unusual noises.
In cold climates with high heating demands, a 95%+ AFUE furnace typically pays for the extra cost within 5-7 years through energy savings. In mild climates, the payback period is longer.
Most furnace replacements are completed in 4-8 hours. Complex installations with venting changes or electrical upgrades may take a full day.
Equipment prices barely move by season, but demand does. From December to February most replacements are no-heat emergencies, so customers wait longer, have less time to compare quotes, and after-hours rates apply. For contractors, fall is the time to quote planned replacements to customers whose furnace is 15 years or older, before it fails on the coldest night.
A common rule: multiply the furnace age by the repair cost. Over $5,000 (for example, an 18-year-old furnace with a $300 repair), replacement usually makes more sense. A cracked heat exchanger, repeated ignition or inducer failures, or a furnace over 20 years old points to replacement. Give the customer both options on one quote, repair and replace, so the choice is theirs.
