AfterHow Much Does AC Installation Cost in Las Vegas?
AC installation in Las Vegas typically costs between $3,500 and $7,500 for a complete system replacement in a standard 1,200 to 2,200 square-foot home. The final number depends on system size, efficiency rating, and the condition of your existing ductwork. Most homeowners we install for in Las Vegas land right in the middle, around $5,000 to $6,000 for a 3-ton, 16 SEER unit, which matches what we see across Summerlin, Henderson, Spring Valley, and Centennial Hills.
AC Installation Cost Breakdown (2026)
Here’s what the numbers look like in the Las Vegas market this year. These are the prices we quote in writing before any work starts, so you know exactly where your money goes.
| Line Item | Cost Range | What It Covers |
|---|---|---|
| New AC condensing unit (outdoor) | $1,800 – $3,500 | The outdoor compressor/condenser, sized to your home’s cooling load. |
| New evaporator coil (indoor) | $800 – $1,600 | The indoor coil that pairs with the outdoor unit. Mismatched coils kill efficiency. |
| Labor and installation | $900 – $1,800 | Removal of old equipment, new refrigerant lines, brazing, electrical, and testing. |
| Refrigerant (R-410A or R-454B) | $200 – $600 | Newer systems use R-454B, which runs a bit more than older R-410A. |
| Smart thermostat | $150 – $350 | Optional, but worth it in Southern Nevada heat for scheduling and setback savings. |
| Ductwork modifications | $0 – $1,500 | Only if your existing ducts have leaks, bad sizing, or insulation problems. |
If you’re replacing both the indoor and outdoor units at the same time (a “full system replacement”), the total usually falls between $4,500 and $7,500. If you only need the outdoor condenser swapped and your indoor coil is compatible, you might land closer to $3,500.
What Affects AC Installation Pricing in Las Vegas
No two homes in the Las Vegas Valley price the same. Here’s what moves the number.
- Home size and cooling load: A 1,000-square-foot condo in Summerlin calls for a 1.5-ton to 2-ton unit. A 3,000-square-foot two-story in Southern Highlands needs 4 to 5 tons. More tonnage means more equipment cost, plain and simple.
- SEER rating: Higher-efficiency units (say, 18 SEER versus 14 SEER) cost more up front but pull down your NV Energy bills when summer temps sit at 110 for weeks. A 16 SEER unit is the sweet spot most Las Vegas homeowners pick.
- Single-stage vs. two-stage vs. variable-speed: Variable-speed and two-stage systems run $1,200 to $2,500 more than single-stage. They hold tighter temperature and humidity control, which matters in a desert climate where nights finally drop but walls hold heat.
- Refrigerant type: As of 2026, new systems use R-454B, a low-global-warming refrigerant. It’s slightly pricier to fill and requires techs to have updated training, which adds a small amount to install cost.
- Existing ductwork condition: Older homes in the central Las Vegas area and east side often have leaky or undersized ducts. Sealing and partial replacement is common once we get a camera in there. That’s an honest add-on, not a surprise, because we quote it before we start.
- Access and code requirements: Units on rooftops or in tight side yards take more labor. Clark County and city of Las Vegas permits and inspections are part of our quotes, never a hidden line item.
How to Save on AC Installation
The best lever you have is timing. January through March and October through November are the slow seasons for AC work in Las Vegas. You’ll often see manufacturers running rebates of $300 to $800, and our schedule opens up so you can pick an install time that actually works for you, not one that works around a 115-degree heat wave. And if you book online, you’ll get a live arrival time you can track to your door, not a four-hour window.
Here’s what else moves the number down without cutting corners:
- Replace your indoor coil and outdoor unit together. Mismatched parts from different eras waste energy and shorten the life of both.
- Get your ducts sealed before or during install. Leaky ducts in an attic that hits 140 degrees in July pour cold air into nothing.
- Ask about manufacturer rebates and any active federal or local efficiency incentives. They change by season, but we track them for you.
- Skip the extras that don’t matter for your house. A variable-speed system is great, but if you’re in a 1,100-square-foot ranch in Spring Valley, a solid 16 SEER single-stage unit is likely the right call.
When we quote an AC installation, the price is written before any tool leaves the truck. No same-day upcharges, no “we found something else” at the door. You’ll see the number, approve it from your phone, and know exactly what’s happening from start to finish. Call (725) 220-3488 and we’ll put a number in writing before you commit to anything. And every installation carries our 365-Day Done Right Promise, meaning if something isn’t right within a year, we come back and make it right at no charge.

Here’s how a standard full-system AC Installation goes in a Las Vegas home, from first call to cold air.
- Book online or call. A real person answers 24/7 at (725) 220-3488. No voicemail tree. Tell us what’s going on and we schedule a time that works.
- Get a live arrival window. The day of your appointment, you’ll see your technician’s name, photo, and live location. We track to your door, so you’re not sitting around for a four-hour window.
- Load calculation and quote. Your technician checks square footage, insulation, window orientation, duct condition, and existing equipment. Within the visit, you get a written price for the full install, broken down line by line.
- Approve from your phone. You decide. No pressure, no door-knocker pitch. If the price works, you approve it on the spot and we lock it in writing.
- Installation day. We remove old equipment, install the new system, flush and charge refrigerant, run electrical, and connect your thermostat. Most installs take 4 to 8 hours.
- Post-install walkthrough. We show you the system running, test airflow and static pressure, and document everything with photos. You get a copy, so you see what was done.
- 365-Day Done Right Promise. If anything isn’t right within a full year, we return at no charge. That’s a written guarantee, not a sales promise.

How Much Does AC Installation Cost by System Type?
Here’s how equipment types shake out in Las Vegas pricing in 2026.
- Single-stage 14 SEER, 3-ton: $3,500 – $4,500 installed. Basic, reliable cooling. Good for smaller homes and condos.
- Single-stage 16 SEER, 3-ton: $4,500 – $5,800 installed. The most common install we do in Summerlin, Henderson, and Centennial Hills.
- Two-stage 17 SEER, 3-ton: $5,800 – $7,200 installed. Runs on low stage most of the day, which lowers humidity and evens out temperature swings.
- Variable-speed 18-20 SEER, 3-ton: $7,000 – $9,500 installed. Top-end efficiency, near-silent operation. Ideal for larger two-story homes and anyone who wants the tightest temperature control.
- Heat pump (heating + cooling): $4,500 – $8,500 installed. Great option for Las Vegas winters when you need a bit of heat and full AC for summer.
These are installed prices, including new line sets, pad, electrical disconnect, thermostat wiring, and startup. The only time these numbers climb is when ductwork needs major work or you’re upsizing from a smaller system.
Repair or Replace: When Does a New AC Make Sense in Las Vegas?
If your AC repair quote comes in under $500 on a system under 10 years old, repairing usually makes sense. But if the compressor is gone, the coil is leaking, and your unit is 12-plus years old after a decade of 110-degree summers, replacement often wins. A bad compressor on an old unit can run $1,800 to $2,600, and at that point you’re a third of the way to a new system that runs quieter and pulls less power.
For context, most AC repair costs in Las Vegas run between $150 and $650 for the common stuff like capacitors, contactors, and refrigerant top-offs, which is the term for topping off the coolant your system needs to produce cold air. If you’re on the fence, our technicians will give you an honest read, not a sales pitch. If the repair makes sense, we do the repair and the written guarantee that comes with it. If replacement makes more sense, we give you a written install price and let you decide. To read more about what goes into a full AC installation in Las Vegas, check out our main page on it.
FAQs – AC Installation Cost
How much does AC installation cost in Las Vegas?
AC installation in Las Vegas runs $3,500 to $7,500 for a standard replacement, with most full-system installs landing around $5,000 to $6,000 for a 3-ton, 16 SEER unit. Small condos can come in under $4,000, while larger variable-speed systems run $7,500 and up. Call (725) 220-3488 for a written quote with a price locked before any work starts.
How much is a 3-ton AC unit installed in Las Vegas?
A 3-ton AC system installed in Las Vegas typically costs $4,500 to $6,000 for a 16 SEER unit, depending on your home’s existing ductwork and the efficiency level you choose. Higher-efficiency 18 SEER and above systems run $7,000 to $9,500. We give a free written estimate with no obligation.
Is it cheaper to repair or replace my AC?
If the repair is under $500 and your system is under 10 years old, repair usually wins. If your compressor has failed or the coil is leaking on an older system, a replacement is often the smarter money, since a $2,000 repair on a 12-year-old unit doesn’t extend its life much. We’ll give you a straight answer either way with a written price for both options.
How long does AC installation take in Las Vegas?
A standard full-system AC installation takes 4 to 8 hours from start to finish. Whole-home ductwork replacement can push it to a second day. You’ll get a live arrival time and a clear schedule before we begin, so you know exactly when the job starts and when cold air is coming back.
