IN THIS GUIDE ▾
This page is written for contractors quoting AC unit replacements. It covers what customers expect to pay for an AC unit installed in 2026 ($3,000-$12,000, typically $6,500 for a 3-ton, 16 SEER system), what the equipment and install cost you by tonnage and efficiency, and the margin that leaves. Use the tables to check your price book before you send the quote.
AC Unit pricingby size and type.
AC unit pricing depends on cooling capacity (measured in tons) and SEER efficiency rating. Proper sizing through Manual J calculations ensures optimal performance and energy savings.
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 AC unit priceand 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.
AC capacity is measured in tons, with one ton providing 12,000 BTUs of cooling. Most homes need 2-5 tons based on square footage, climate, and insulation.
Seasonal Energy Efficiency Ratio measures cooling output per energy input. Higher SEER units cost more but reduce electricity bills significantly.
Single-stage units run at full capacity, while two-stage units adjust output for better humidity control and quieter operation.
Premium brands offer better warranties, parts availability, and often quieter operation compared to budget options.
Factors like refrigerant line length, electrical requirements, and condenser placement affect labor costs.
If ductwork is undersized, leaky, or poorly insulated, modifications may be needed for optimal AC performance.
What AC unit sells forby region.
Labor rates, permitting and cost of living move the going rate. Price against your local market, not the national average.
High labor rates and cost of living drive up AC installation prices in major coastal markets.
San Francisco · Los Angeles · New York · Boston · SeattleHot climates create competitive AC markets with many experienced contractors.
Phoenix · Las Vegas · Dallas · Houston · AtlantaLower labor rates and cost of living make AC installation more affordable.

Add-on lines to includein 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 AC unitaccurately.
Customers compare 3-5 quotes on a job this size. The ones that win are rarely the cheapest; they are the clearest. Build your AC unit 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 financingoptions to offer.
Offering a financing path raises close rates on larger tickets. These are the ways customers typically pay for AC unit; 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 central AC units last 15-20 years with proper maintenance. In extreme heat climates like Phoenix, units may last 10-15 years due to higher usage.
A rough estimate is 1 ton per 500-600 square feet, but proper sizing requires a Manual J load calculation that accounts for climate, insulation, windows, and orientation.
In hot climates with high cooling demands, upgrading from 14 to 18 SEER can save $200-$400 annually, paying back the extra cost in 5-8 years.
