IN THIS GUIDE ▾
This page is for contractors quoting complete HVAC system replacements. It covers what customers expect to pay in 2026 ($5,000-$22,000, typically $11,000 for a furnace and AC), what a full changeout costs you in equipment, labor and materials, and the margin that leaves. Bundling heating and cooling lowers your cost per component, so price the package to reflect it without giving away the savings.
HVAC System Replacement pricing by size and type.
Rows are 3-ton systems on existing ductwork at national average prices. Each ton up or down moves the price about $800-$1,000; new ductwork, electrical and hard access are separate lines.
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 HVAC system 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.
Higher AFUE (furnace) and SEER (AC) ratings cost more upfront but reduce energy bills for the 15-20 year system lifespan.
Larger homes need higher capacity systems. Equipment costs scale with BTU output and tonnage required.
Premium brands (Carrier, Trane, Lennox) offer better warranties and reliability. Budget brands (Goodman, Payne) cost less.
If ductwork needs replacement, sealing, or modification, expect significant additional costs.
Older homes may need panel upgrades or new circuits for modern high-efficiency systems.
Adding zone control with multiple thermostats and dampers increases initial cost but improves comfort.
What HVAC system 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.

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 HVAC system 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 HVAC system 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.

Payment and financing options to offer.
Offering a financing path raises close rates on larger tickets. These are the ways customers typically pay for HVAC system 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.
Consider full replacement when both heating and cooling are 15+ years old, repairs are frequent and costly, energy bills are rising, or you're experiencing consistent comfort problems.
Yes, if both units are aging. New systems are designed to work together efficiently, and combined installation typically saves 10-15% on labor costs.
Most complete replacements take 1-3 days. Simple swaps may be done in a day, while complex installations with ductwork take longer.
