AC Unit Prices by Ton in 2026: 1.5 to 5 Ton, Real Numbers

AC pricing splits into two numbers nobody shows you side by side: what the equipment costs, and what the installed quote says. Here's both, by tonnage, for 2026 — so you know what you're actually paying for before anyone's in your driveway.

The Price Table

*Complete matched system — condenser plus indoor coil — at 13.4–15.2 SEER2, current-generation refrigerant (R-32 or R-454B), 10-year registered warranty. Higher efficiency tiers add $1,500–$4,000.

Reading the Gap

The spread between columns is $3,000–$7,000 at every size. Real labor and materials on a standard changeout justify $2,000–$3,500 of it. The rest is dealer overhead and margin — the part you control by buying equipment at wholesale and paying separately for the day of skilled installation labor the job actually takes.

Don't Buy by Price Alone — Size First

Notice the equipment steps between sizes are small ($150–$400). That's a trap in both directions: upsizing “to be safe” costs little upfront and a lot forever — oversized systems short-cycle, dehumidify poorly, and die younger. The right size comes from square footage, insulation, windows, ceiling height, and climate. Match the load, not the budget and not the old unit's sticker (it may have been wrong for 15 years).

What Else Lands on the Final Bill

• Air handler replacement (if the indoor unit's done too): $1,100–$2,500 equipment
• Line set replacement when the old one can't be reused: $300–$900
• Electrical updates — disconnect, whip, breaker: $150–$600
• Pad, drain work, small parts: $100–$400

The Bottom Line

In 2026, the hardware for a complete AC system costs $2,400–$5,000 — at every tonnage, far less than the installed quotes orbiting it. Know your size, buy the equipment at the published wholesale price, and pay fair labor on top. The form below sizes your home and returns real wholesale numbers, usually within the hour.
