Why AC costs what it does here
- Las Vegas averages 78 days a year at 100°F or hotter (1991 to 2020 normals). Source
- 2024 set records: 101 days at 100°F or hotter, and an all-time high of 120°F on July 7. Source
Units here run harder and longer than almost anywhere in the country, so they wear out sooner and contractors are slammed every summer. That's when quotes are highest and you have the least time to shop around. If your system is getting old, getting quotes in the fall or winter gives you room to compare.

What these prices cover: installed, meaning equipment, labor, pad, refrigerant lines, electrical hookup, permit and haul-away. Ducts, a crane for roof units and a new thermostat are often extra. What's actually in a quote
What moves the price
- Size. Most Las Vegas homes run 3 to 5 tons. Bigger costs more, and too big cools worse, so ask for a load calculation instead of just matching your old unit.
- Efficiency. Higher SEER2 costs more upfront and less every summer after. With Vegas power bills, that math tends to work out faster than in milder places.
- AC only or the whole system. Swapping just the outdoor unit is cheaper, but pairing new and old parts can hurt efficiency and limit the warranty.
- Ducts. Leaky or undersized ducts can add a lot. Check if duct work is in the quote or quietly left out.
- Roof units. If yours sits on the roof, a crane or extra labor may be in the price.
- Labor warranty. Two quotes with the same equipment can be thousands apart because one covers labor for 10 years and the other for 1.
Ask these before you sign
- Did you do a load calculation, or are you matching my old size?
- What are the exact model numbers, outside and inside?
- Is the permit, pad, thermostat, haul-away and duct work included?
- How long is the labor warranty, not just parts?
- Does this unit qualify for a rebate, and who files it?
