AC Installation & Replacement in Las Vegas
A residential AC replacement in Las Vegas typically runs $8,000–$16,000 installed, depending on tonnage, efficiency, and whether the air handler and line set are replaced. Proper sizing uses a Manual J load calculation, not just matching the old unit's tonnage.

How the visit works
1. Load calculation
We size to the home's actual heat load, orientation, insulation, and window area — oversizing short-cycles and leaves humidity behind.
2. Options in writing
Good/better/best with efficiency ratings, warranty terms, and rebate eligibility spelled out.
3. Permitted install
Clark County permit pulled, new pad, disconnect, whip, and line set as needed.
4. Commissioning
Charge weighed in, airflow set, static pressure measured, and results left with you.

AC Installation & Replacement questions
How long does an AC replacement take?
Most single-system changeouts are done in one day. Package units and duct work can extend to two.
Do I need a permit?
Yes — Clark County requires a permit for equipment replacement. We pull it and handle the inspection.
What efficiency makes sense in Las Vegas?
With our cooling hours, stepping from base efficiency to a two-stage or variable system usually pays back faster here than in milder climates.
