Short answer
There's no single price. Cost depends on system size (tonnage), efficiency (SEER2), whether ductwork or electrical work is needed, and the equipment brand. For a national reference point, Trane reports that central AC replacement averages roughly $6,958–$13,418 installed in 2026, with basic systems starting lower.

Published national price ranges
Laredo AC Pros doesn't set contractor prices, and we don't want to guess at yours. For a reference point, here's what a major manufacturer publishes:
- Trane reports 2026 national averages of about $6,958–$13,418 installed for AC replacement, with a broader range from about $3,900 for a basic unit to $13,500 at the high end.
National averages are a starting point, not a Laredo quote. Your price depends on the factors below.
What drives the price
- System size (tons). Larger homes need more capacity, but bigger isn't automatically better. Sizing should come from a load calculation.
- Efficiency (SEER2). Higher-efficiency and variable-speed systems cost more upfront and can cut cooling bills, which matters in a climate where the AC runs most of the year.
- System type. AC with a furnace or air handler, heat pump, packaged unit, or mini-split.
- Matched indoor coil or air handler. Replacing only the outdoor unit is cheaper upfront but often a poor long-term choice.
- Ductwork condition. Leaky or undersized ducts may need repair or replacement (see air ducts).
- Electrical work. New breaker, disconnect or wiring upgrades.
- Installation difficulty. Tight attics, long line sets, roof access, or crane work for rooftop units.
- Permits, haul-away and refrigerant recovery.
- Warranty. Extended labor warranties add cost but add protection.

📞 (956) 307-9262How to compare quotes
Ask every contractor to put the following in writing so you're comparing the same thing:
- Brand and model numbers for the outdoor and indoor units, tonnage and SEER2
- Whether a load calculation was done
- Line set, thermostat, pad, drain, electrical and duct work included or excluded
- Permit and inspection
- Equipment and labor warranty length
- The contractor's TDLR license number
Be cautious with a quote that's far below the others. It may leave out a matched coil, permits or proper installation steps.
Repair or replace?
Rule of thumb: age × repair cost. If the result is over about $5,000, replacement is often the better value. Systems using R-22 refrigerant or older than 10–15 years are usually better candidates for replacement than for big repairs. More on this on our AC replacement page.
