AfterAC Installation in Las Vegas, NV
A new AC installation in Las Vegas typically runs between $6,500 and $14,500 for a complete system, with most homeowners in Summerlin, Henderson, and Spring Valley paying around $8,000 to $11,000 for a mid-range setup. The final number depends on your home’s square footage, the SEER rating you choose, and whether your ductwork needs updating. Coldharbour Heating & Air has installed residential AC systems across the Las Vegas Valley since 2003, and every job starts with a written price before any work begins.
If your current unit is limping along and you’re weighing repair against replacement, our AC Repair & Installation page covers the full picture. This page is focused on one thing: what it actually costs to get a new system installed here in Las Vegas, and how we do the work.

When You Need AC Installation
Las Vegas summers don’t forgive a failing AC. If you’re noticing any of the following, it’s worth getting an honest assessment, either toward AC Repair & Installation Near Me in Las Vegas, NV or a full install:
- Your system is 12 to 15 years old. That’s the typical lifespan in our climate. Once a unit passes that mark, repairs get more frequent and more expensive, and the refrigerant it uses may no longer be manufactured.
- Repairs are stacking up. If you’ve spent more than $800 on repairs in the last two years, the math starts tilting toward replacement, especially in neighborhoods like Green Valley and Centennial Hills where systems run hard from May through September.
- Uneven cooling between rooms. The living room feels fine, but the back bedroom is eight degrees warmer. That’s often a sign of failing ductwork or an undersized system, both of which an install can correct.
- Your energy bills keep climbing. An aging unit works harder to produce the same cooling. Annual bill increases of 10 percent or more, without a change in usage, suggest declining efficiency.
- The unit uses R-22 refrigerant. R-22 was phased out of production in 2020. If your system leaks, the remaining supply is expensive and dwindling. New systems use R-410A or newer refrigerants.
- Strange noises or short cycling. Grinding, rattling, or a unit that turns on and off every few minutes means the system is near the end. In Las Vegas’s dry, dusty air, compressor wear happens faster than in milder climates.
Our AC Installation Process
We don’t do surprise installs. Here’s how every job runs, step by step:
- You call or submit a request. A live person answers, day or night. We ask a few questions about your home’s square footage, the age of your current unit, and what’s going wrong. Then we set a firm arrival window.
- We assess the home, not just the unit. The technician checks square footage, ceiling height, window exposure, insulation levels, and existing ductwork. A Las Vegas-specific consideration: west-facing homes in neighborhoods like Mountain’s Edge and Providence take a heavier afternoon heat load, which affects sizing.
- You get a written price before any work begins. Not a verbal estimate. A written quote that breaks down the equipment, labor, and materials. That price holds.
- We install the system. The technician removes the old unit, installs the new one, and connects it to the existing ductwork. If your ductwork is undersized or damaged, we’ll have flagged that in step two and given you a separate line item.
- We test and walk you through it. The system is cycled, refrigerant levels are verified, and airflow is checked. You get a rundown of the thermostat settings and what to expect in the first few weeks.
- You receive the 365-Day Done Right Promise, in writing. If anything about the installation is not right within a full year, we come back and correct it at no charge. That guarantee is on paper before the technician leaves.
AC Installation Pricing in Las Vegas
Here’s what we see across the valley, based on our work in Summerlin, Henderson, North Las Vegas, and the surrounding communities:
| System Type | Typical Range (Parts, Labor, Installation) | Best For |
|---|---|---|
| Single-stage, 14 SEER basic system | $6,500 – $8,500 | Budget-conscious homeowners, smaller single-story homes |
| Single-stage, 16 SEER mid-range system | $8,000 – $10,500 | Most homes under 2,000 sq ft |
| Two-stage, 17 – 18 SEER high-efficiency system | $10,000 – $13,000 | Two-story homes, larger floor plans, homes over 2,500 sq ft |
| Variable-speed, 20+ SEER premium system | $12,500 – $14,500+ | Homes over 3,000 sq ft, homeowners prioritizing efficiency and quieter operation |
What changes the price? Three main things: the home’s square footage and duct layout (an awkward attic or tight closet access adds labor time), the SEER rating (higher efficiency costs more upfront but lowers summer electric bills, which matter in Las Vegas’s heat), and whether new ductwork or an updated thermostat is needed. If your electrical panel needs an upgrade to handle the new system, that’s a separate line item and the technician will tell you before any work starts.
We carry Lennox, Goodman, and Rheem units, and our technicians work on whatever brands are already in the home. If you’re replacing a York system, for instance, we’ll match the existing configuration or explain why a different brand makes sense for your home. Quotes are free. Call (725) 726-3813 and we’ll give you a straight answer on what your install would cost.
FAQs – AC Installation
How much does AC installation cost in Las Vegas?
A full AC installation in Las Vegas costs between $6,500 and $14,500, with most homes landing in the $8,000 to $11,000 range depending on square footage, SEER rating, and ductwork condition. We provide a written price before any work begins, so you’ll know the exact number before you commit. Call (725) 726-3813 for a free estimate on your home.
Is it cheaper to repair or replace my AC?
It’s cheaper to repair in the short term, but if your unit is over 12 years old or you’ve spent more than $800 on repairs in the last two years, AC Replacement often costs less over the next five years. The answer depends on your specific system, and we’ll give you an honest read either way without pushing toward replacement if repair makes sense.
How long does AC installation take in Las Vegas?
A standard residential AC installation takes one full day, roughly six to eight hours, for a straightforward swap of the outdoor condenser and indoor air handler. If ductwork modifications or a thermostat upgrade are part of the job, it can run a second day. We’ll give you a firm arrival window before the appointment and stick to it.
Can you install an AC the same day?
In many cases we can install a system the same day or within 24 hours, depending on equipment availability. When Las Vegas hits a heat wave, demand spikes, but our live-person phone coverage at (725) 726-3813 means you’ll get a straight answer on timing within minutes, not a voicemail.
