Repair or Replace the AC? How Las Vegas Technicians Decide

Updated 2026-11-05 · For Las Vegas homeowners

On a unit under ten years old, repair almost always wins. Over fifteen, replacement almost always wins. The hard decisions are the years in between, and Las Vegas summers tilt them toward replacement sooner than in milder cities.

The rules of thumb

What replacement costs here

A standard 3 to 5 ton split system installed with permit runs about $5,000 to $14,000 in Las Vegas, more for high-efficiency or two-stage equipment and for rooftop package units that need a crane. A new system typically cuts summer cooling costs noticeably against a 15-year-old unit and comes with a 10-year parts warranty if registered.
