AfterAC Replacement in Las Vegas, NV
AC replacement in Las Vegas typically costs between $6,800 and $14,500 for a complete system changeout, depending on home size, efficiency rating, and ductwork condition. Most full replacements are completed in a single day, though some two-stage and variable-speed installs run into a second morning. If your unit is over 12 years old and the compressor has failed, replacement usually makes more financial sense than repair. Call Cold Harbour Heating and Air Las Vegas at (725) 726-3813 for a written quote before any work begins.
We’re an independently owned and operated member of the Kingswell network, serving Las Vegas since 2003. That matters because AC replacement is the single biggest HVAC decision a homeowner makes, and you should know exactly who is walking through your door and exactly what the work will cost before a single tool comes out. Our AC Repair & Installation in Las Vegas team handles replacements across Summerlin, Henderson, North Las Vegas, Centennial Hills, Spring Valley, and the older neighborhoods around downtown where homes often still run original ductwork.
Before we get into pricing and process, let’s be direct about what a replacement involves: we remove your old condenser and air handler (or evaporator coil, if the furnace stays), inspect the duct connections and electrical disconnect, set the new equipment, perform a Refrigerant Recharge to manufacturer spec, and verify airflow and temperature drop before we leave. Every replacement carries the same written guarantee we put on a $200 repair: if something isn’t right within 365 days, we come back and correct it at no charge.
When You Need AC Replacement
Not every breakdown means a new system. A Capacitor Replacement, a worn contactor, or a refrigerant leak on a 6-year-old unit is almost always worth repairing. But Las Vegas heat punishes air conditioners harder than almost any city in the country, and there is a point where putting money into an aging system stops making sense. Here are the signs we tell homeowners to watch for:
- The compressor is dead or failing. When the compressor goes on a 10-plus-year-old unit, you’re looking at a repair bill that can run $1,800 to $3,200. In most cases, that money is better spent toward a new system with a fresh manufacturer warranty.
- The system still runs on R-22 refrigerant. If your condenser was installed before 2010, it likely uses R-22 (Freon), which is no longer produced in the U.S. and now costs $150 to $300 per pound to source. Recharging an R-22 system in Las Vegas often exceeds $1,000, and that money buys you no new longevity.
- Repair costs are stacking up. If you’ve spent more than $1,500 on repairs in the last two years, you’re chasing a system that’s telling you it’s done. A new unit costs less per year of service than a 14-year-old one that needs a major part every spring.
- Your energy bills have climbed steadily. A 14-year-old 13-SEER unit can cost $120 – $180 more per month to run in July and August than a modern 16-SEER or 17-SEER replacement. In Las Vegas, where AC runs five to six months a year, that difference adds up faster than most people expect.
- The condenser is rusted, leaking, or blowing warm air. Corrosion from our hard water and summertime dust storms shortens outdoor coil life here. Once the coil rots through, the system has reached end of life.
- Your home never cools evenly anymore. Hot upstairs, cold downstairs, or one bedroom that never gets comfortable can point to an aging blower, undersized ductwork, or a system that was never matched to your home’s load in the first place.
Our AC Replacement Process
We follow the same five-step process on every replacement in Las Vegas, from a 1,200-square-foot condo near the Strip to a two-story house in The Lakes. The Kingswell Way is built on five commitments: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails. That’s how we’ve delivered our ac repair installation services since 2003.
- Walkthrough and load review. Every replacement starts with a free in-home visit. Victor Mancini or one of our senior technicians walks through the house, checks the existing equipment, measures the square footage, and reviews the duct layout. We don’t sell by tonnage guesswork, and we don’t quote 3.5 tons for a home that really needs 3.
- Written proposal with exact price. Before we leave that first visit, you get a written price for the full replacement, including equipment, labor, any needed duct transitions, and disposal of the old unit. That price does not change at the door on install day. It’s in writing, the way it should be.
- Installation day, on schedule. We give you a firm arrival window and we keep it. A replacement crew is typically two technicians, both background-checked and uniformed. Most single-system replacements in Las Vegas run about six to eight hours from start to system startup.
- Startup, airflow, and refrigerant verification. Once the new system is in, we verify subcooling and superheat against the manufacturer’s spec, measure the temperature drop across the coil, and confirm the airflow is right in each room. We don’t just flip the breaker and walk away.
- Written guarantee and cleanup. The old equipment is hauled off, the work area is swept and vacuumed, and you receive the written 365-Day Done Right Promise in hand. If anything about the installation is not right within that year, we return and correct it at no charge, no argument.
AC Replacement Pricing in Las Vegas
Here’s the honest reality of Las Vegas AC replacement costs. The price depends on three things: the size of the system (in tons or BTUs), the efficiency rating (SEER2), and whether your existing ductwork and electrical can support the new equipment. A straightforward condenser-and-coil swap in a one-story home on the west side will fall near the bottom of the range. A full system with new furnace, upgraded duct transitions, and a variable-speed air handler in Summerlin will land near the top.
| Replacement Scope | Typical Range in Las Vegas |
|---|---|
| Condenser only, 3-ton, 14 – 15 SEER2 | $3,800 – $5,600 |
| Condenser + evaporator coil, 3 – 4 ton | $5,400 – $8,200 |
| Full system (condenser, air handler, coil), 16 – 17 SEER2 | $8,500 – $12,900 |
| Full system with variable-speed air handler, 18+ SEER2 | $12,000 – $16,500 |
| Ductwork replacement or major duct sealing (if needed) | $1,800 – $6,500 |
Those are installed prices, not equipment-only numbers. What moves the needle in Las Vegas specifically: older homes in the downtown corridor and East Las Vegas often need electrical disconnect upgrades or new plenum transitions, which run $350 – $700. Homes built before 1995 frequently have undersized return air, and adding a return in a hallway ceiling adds $500 – $900. We price all of it up front so there are no surprises.
We install and service equipment from Lennox, Goodman, and Rheem, among others. The right brand for your home depends on your budget, your ductwork, and how long you plan to stay in the house. A Goodman system is the best value on the market right now. Lennox gives you the lowest sound ratings and strongest efficiency in the high end. Rheem sits in the middle with an excellent corrosion-resistant coil for our desert air. We’ll walk you through the tradeoffs honestly and let you decide.
Every proposal includes a free estimate. Call (725) 726-3813 and we’ll schedule a walkthrough, usually within a couple of days. The estimate is in writing and the price on it is the price you pay.
FAQs – AC Replacement
How much does AC replacement cost in Las Vegas?
A full AC replacement in Las Vegas runs $6,800 to $14,500 for most homes, with condenser-only swaps starting around $3,800. Your exact price depends on system size, SEER2 rating, and the condition of your ductwork. Call (725) 726-3813 for a written, no-obligation quote for your specific home.
Is it cheaper to repair or replace my AC?
If your compressor has failed and the unit is over 10 years old, replacement is almost always cheaper over a three-year horizon. A Compressor Repair runs $1,800 to $3,200 and buys you no new warranty on the rest of the system. If the unit is under 8 years old and the repair is under $800, repair is usually the smarter call. We’ll tell you which side of the line you’re on and why.
Can you replace my AC today or tomorrow?
In most cases yes. We carry common 3-ton and 4-ton condenser and air handler combinations in local stock, and in a Las Vegas heat wave we prioritize full failures. Call (725) 726-3813 and a live person answers, day or night. We’ll give you a firm arrival window, not a four-hour “sometime” window.
Do you handle the permits and old unit disposal?
Yes. We pull the required City of Las Vegas or Clark County mechanical permit for every replacement, and we haul away and properly dispose of the old condenser and air handler. You never have to call a scrap company or deal with a refrigerant recovery company. It’s handled the same day.
What’s the warranty on a new system?
You get two layers of protection: the manufacturer’s parts warranty (typically 10 years when registered, which we do for you) and our written 365-Day Done Right Promise. If anything about our installation fails within that year, we come back and correct it at no charge. The guarantee is on paper before we leave, not a verbal promise.
