AfterAC Replacement in Las Vegas, NV
AC replacement in Las Vegas typically costs between $4,800 and $12,500 for a full system swap, depending on your home’s square footage, SEER2 efficiency rating, and whether ductwork modifications are needed. Most replacements take one full day, and in peak summer months, we schedule them within 3 to 7 days of your call. If your current unit is leaking refrigerant, tripping breakers, or racking up repair bills every summer, replacing it often costs less over five years than keeping it patched together. At Halden Heating and Air Las Vegas, you’ll get a written price before we touch anything, and you can call us at (725) 220-3488 anytime, day or night, to talk through your options.
This page covers how we handle AC replacement as part of our broader AC Repair & Installation in Las Vegas work. If you’re not sure whether repair or replacement makes sense, our AC Repair & Installation team will walk you through the math honestly, including when a repair still makes sense and when it’s money down a drain.
Key Takeaways
- Full AC replacement in Las Vegas runs $4,800 – $12,500, with most homes landing between $6,000 and $9,000 for a mid-efficiency system.
- If your AC is over 12 years old and the compressor or coil fails, replacement usually beats repair on total cost over 3 – 5 years.
- We give you a locked written price before any work starts, and every install carries the 365-Day Done Right Promise.
- You can book online, track your technician’s live arrival, and talk to a real person at (725) 220-3488 around the clock.
When You Need AC Replacement
Not every cooling problem in Las Vegas means a full replacement. Some are straightforward repairs. But certain signs point squarely at replacement, and a few are especially common in our climate:
- Your AC is 12 to 15 years old. Most systems in Southern Nevada last 12 to 15 years. Desert heat and dust shorten that lifespan compared to coastal cities. If your unit is in that range and a major component fails, replacement is usually the smarter spend.
- The compressor died or is failing. The compressor is the heart of your AC, the pump that circulates refrigerant. A compressor replacement on an older R-22 system can run $2,500 to $4,000, often within striking distance of a new, more efficient system that comes with a fresh factory warranty.
- R-22 refrigerant leaks. Many pre-2010 systems still run on R-22 (Freon), which was phased out of production in 2020. The remaining supply is expensive, and a recharge can cost $300 to $600 per pound. If your system needs multiple pounds each summer, you’re feeding a losing battle.
- Repair bills are climbing. If you’ve spent more than $800 on repairs in the last two years, especially across separate components like coils, capacitors, and fan motors, that system is telling you something. A new unit from brands like Lennox or Goodman often pays for itself in reduced repair costs and lower summer electric bills.
- Rooms stay uneven or never cool down. In neighborhoods from Summerlin to Henderson, we regularly see undersized or worn-out systems that run constantly and never hit the setpoint. If your AC runs 14-plus hours a day in July and the house still feels warm, the system is likely past its useful capacity.
- Your electric bills keep climbing. A SEER2 rating below 14 on an aging system means you’re paying more per degree of cooling. Newer units from Rheem or York in the 16 to 18 SEER2 range can cut summer cooling costs by 20 to 30 percent.
When we come out, we don’t push replacement. We show you the numbers on both paths, repair and replace, and you decide. Our job is to make sure you have the facts in plain English before you spend a dollar.
Our AC Replacement Process
Here’s how a full replacement works with our team, step by step, so you know exactly what to expect from the first call to the final walkthrough:
- Call or book online. You reach a live person at (725) 220-3488 any time, or you book through our online scheduling. You’ll get a live arrival time, not a four-hour window, and you can track your technician to your door.
- Home survey and load calculation. Our technician measures your home’s square footage, checks ductwork condition, evaluates insulation, and looks at window exposure. This isn’t guesswork, it’s a Manual J load calculation, the industry standard for right-sizing a system. An oversized unit cools fast but short-cycles, leaving humidity high and components stressed. An undersized one runs forever and never satisfies.
- Written price, before any work. Before we touch a tool, you get a locked written quote. No door-step add-ons, no surprise charges. The price we show you is the price you pay. We’ll give you options across efficiency tiers and brands like Lennox, Goodman, and Rheem, with plain-English explanations of what each tier gets you.
- Scheduled installation. Most full replacements take one day. We coordinate any permits your municipality requires, and our background-checked, uniformed technicians handle everything from old-unit removal to new-system startup.
- Post-install verification and walkthrough. After startup, we test refrigerant charge, airflow, and temperature split across the system. We walk you through the new thermostat, show you before-and-after photos, and register your equipment warranty. Every install is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right, in writing.
AC Replacement Pricing in Las Vegas
Here’s what you can expect to pay for a full AC replacement in Las Vegas, based on what we see across the valley in 2025:
| System Type | Typical Installed Cost | What You Get |
|---|---|---|
| Basic 14 SEER2 single-stage, 2 – 3 ton | $4,800 – $6,500 | Reliable cooling for smaller homes, condo units, or budget-conscious buyers. Brands like Goodman or York. |
| Mid-range 16 SEER2 single-stage or two-stage, 3 – 4 ton | $6,500 – $9,000 | Better humidity control, quieter operation, and 15 – 20% lower cooling bills than older 10 – 12 SEER units. Lennox, Rheem, or Goodman. |
| High-efficiency 18+ SEER2 variable-speed, 4 – 5 ton | $9,000 – $12,500 | Inverter-driven compressors, near-silent operation, and peak summer comfort with the lowest energy use. |
What moves the number: square footage and tonnage (a 2,000-square-foot home typically needs 3 to 4 tons), whether your existing ductwork or electrical panel needs updates, whether you’re switching from R-22 to a modern refrigerant, and how hard the install site is to access. A rooftop unit in an older part of town costs more to swap than a ground-level condenser on a newer build.
Every quote we give is free, and the price is locked in writing before any work starts. That’s not a promotion. That’s how we operate on every single job. Call (725) 220-3488 for an exact number on your home. The estimate takes about 30 to 45 minutes on site, and you’ll have a written price in hand before we leave.

FAQs – AC Replacement
How much does AC replacement cost in Las Vegas?
Most full AC replacements in Las Vegas run between $4,800 and $12,500, with the typical single-family home landing around $6,500 to $9,000 for a mid-efficiency 16 SEER2 system. The final number depends on your home’s tonnage requirement, ductwork condition, efficiency rating, and installation difficulty. Call (725) 220-3488 for a free, written quote specific to your home.
Is it cheaper to repair or replace my AC?
If your repair will cost more than $2,500 and your system is over 10 years old, replacement is usually the better five-year move. A common rule of thumb is the $5,000 test: multiply the repair cost by the unit’s age. If the result exceeds $5,000, replacement typically wins. We’ll run the numbers with you on site so you’re deciding with facts, not a sales pitch.
Can you replace my AC the same day?
In most cases, we can schedule your full replacement within 3 to 7 days, and during extreme heat waves we prioritize no-cool emergencies. A full system swap takes about one day, though larger homes or ductwork updates can extend that. Call (725) 220-3488 and we’ll tell you straight what our schedule looks like this week.
Do you offer financing or payment plans?
We can walk you through financing options during your free estimate. A new system is a real investment, and we’ll show you the monthly math, not just the headline number, so you can decide what fits your budget. Call (725) 220-3488 and ask about financing when you book your estimate.
What brand of AC should I get?
The right brand depends on your budget, efficiency goals, and whether you want single-stage, two-stage, or variable-speed cooling. We install and service Lennox, Goodman, Rheem, and York, among others, and we’ll give you a straight recommendation based on your home, not our inventory. Every brand we install carries a factory warranty plus our 365-Day Done Right Promise.
