AfterRefrigerant Recharge in Las Vegas, NV
A refrigerant recharge in Las Vegas typically runs $180 to $430, depending on the refrigerant type, leak location, and your AC system’s size. It restores the cooling fluid (refrigerant) your air conditioner needs to pull heat out of your home. If your system is low, it’s not a “top-up and forget” situation; a proper recharge starts with finding why the refrigerant level dropped. Our AC repair installation technicians don’t just add coolant. They trace the leak, repair it when practical, and only then recharge and verify the system. Victor Mancini and our team have handled thousands of these jobs across Las Vegas since 2003, always with a written price before work starts and a 365-day guarantee on the repair. Call us at (725) 726-3813 any hour for a free estimate.
Refrigerant recharge is part of the broader AC Repair & Installation work we do across the valley. If your system is blowing warm air on a 110-degree afternoon in Summerlin or Henderson, low refrigerant is a likely cause. Refrigerant (Freon or, in newer systems, Puron) is the fluid that circulates between your indoor evaporator coil and outdoor condenser. It changes from liquid to gas and back, absorbing and releasing heat. When the level drops, the system loses capacity, runs longer, and can ice up. The job is called a recharge because we’re bringing the system back to its factory-specified charge.
We work on all major residential brands, including Lennox, Goodman, and Rheem systems found throughout Las Vegas homes, and our AC Installation expertise covers every model year. Whether your unit was installed in 2005 or 2020, our technicians can determine the correct refrigerant type and charge level. Most recharges are completed same day. A live person answers our phone 24/7, so if your AC quits at 2 a.m. in July, you’re not leaving a voicemail and hoping.

When You Need Refrigerant Recharge
Your AC can be low on refrigerant for months before it fails completely. You’ll notice the decline in performance first. Here are the signs we see most often in Las Vegas homes:
- Warm air from vents: The AC runs but the air coming out feels warmer than it used to. If the temperature split between supply and return air is under 15 degrees, the system isn’t cooling as it should. Low refrigerant is a prime suspect.
- Ice on the refrigerant lines: You may see frost or ice on the copper line connecting the outdoor unit to the indoor coil. This happens when low pressure drops the coil temperature below freezing. Ice blocks airflow and makes the problem worse. Shut the system off and call us.
- Longer run times and higher electric bills: A low charge makes the system run constantly to try to hit the thermostat setting. Las Vegas summers already push AC hard, so a system that never cycles off is wasting electricity. If your NV Energy bill jumped without a rate change, low refrigerant could be why.
- Hissing or bubbling noises near the indoor unit: A refrigerant leak sometimes makes a faint hissing or gurgling sound at the coil. It’s not always audible, but if you hear it, don’t ignore it.
- Compressor short-cycling or shutting down: Modern systems have low-pressure switches that shut the compressor off to protect it. If your outdoor unit clicks on and off repeatedly, the system may be locking out due to low charge.
- The system is old and never serviced: Refrigerant doesn’t get used up; it leaks. A 12-year-old Goodman or Rheem unit that has never been recharged but has slowly lost cooling performance likely has a slow leak. An inspection will confirm it.
Any of these symptoms should be checked by a trained technician. Refrigerant work requires EPA Section 608 certification, and adding refrigerant to a leaking system is both wasteful and illegal. Our technicians are certified and experienced with all refrigerant types, including R-22 (Freon) for older systems and R-410A (Puron) for newer ones.
Our Refrigerant Recharge Process
Every recharge we do follows a written, repeatable process. It’s part of The Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, come back if it fails. Here’s exactly how a refrigerant recharge goes at Cold Harbour Heating and Air Las Vegas:
- System inspection and temperature check: We measure the temperature split across your evaporator coil, check the outdoor condenser for proper airflow, and listen for compressor issues. This tells us whether low refrigerant is the real problem or if something else (a clogged filter, failed capacitor, dirty coil) is the culprit.
- Leak detection: Refrigerant doesn’t vanish. Before adding anything, we locate the leak using an electronic leak detector and, where possible, a visual inspection of the coil and line set. Common leak points in Las Vegas systems are the evaporator coil (due to the high run hours in our climate) and flare fittings at the connections.
- Written estimate: Once we know the leak location and the repair needed, we hand you a written price for the repair and the recharge. That price does not change at the door. If a leak repair isn’t practical (for example, a severely corroded coil on a 15-year-old unit), we’ll tell you that too and explain whether replacement makes more financial sense.
- Leak repair (if applicable): Many leaks can be repaired by replacing a fitting, brazing a crack, or replacing the Schrader valve core. If the coil needs replacement, we’ll quote that separately and install a new one before recharging.
- Evacuation and recharge: We pull a deep vacuum on the system to remove air and moisture, then add the exact amount of refrigerant specified by the manufacturer. The correct charge is measured by weight and verified with superheat or subcooling readings, not by guesswork.
- Verification and documentation: We run the system for 15 to 20 minutes to confirm the temperature split is right and the pressures hold steady. Before we leave, you get a written summary of the work and the 365-day Done Right Promise covering the repair. If the same problem returns within a year, we come back at no charge.
Refrigerant Recharge Pricing in Las Vegas
Most refrigerant recharges in Las Vegas fall between $180 and $430. The biggest variable is whether the system uses R-22 or R-410A. R-22 was phased out of production in 2020, and its remaining stock is expensive. If you have an older Lennox or Rheem system from before 2010, you may still be running R-22, and a recharge could run at the higher end of that range. R-410A systems are cheaper to recharge, typically $180 to $300, assuming no major leak repair is needed. Here’s a breakdown of what you’re paying for:
| Service Item | Typical Cost in Las Vegas |
|---|---|
| Leak detection and system diagnosis | $75 – $150 |
| R-410A refrigerant (per pound, including labor) | $60 – $110 per lb |
| R-22 refrigerant (per pound, including labor) | $120 – $200 per lb |
| Typical residential system recharge (2-5 lbs) | $180 – $430 total |
| Evaporator coil replacement (if leak is in coil) | $950 – $1,800 |
These are honest ranges for the Las Vegas market, not national averages. A two-bedroom condo in Downtown Las Vegas with a 2-ton Goodman system will hold less refrigerant than a 5-ton York system cooling a Summerlin home, so the recharge cost scales with system size. No one can give you an exact price over the phone without seeing the system. That’s why our estimates are free and why we put the number in writing before the work starts.
Is it cheaper to keep recharging than to fix the leak? In the short term, sometimes. In the long term, no. Every recharge without a leak repair is money spent on refrigerant that will escape again. We’ll give you a straight answer about whether the leak repair is worth it based on your system’s age and condition. Call (725) 726-3813 for a free estimate, and we’ll walk you through the numbers.
FAQs – Refrigerant Recharge
How much does a refrigerant recharge cost in Las Vegas?
A refrigerant recharge in Las Vegas typically costs $180 to $430, including labor, refrigerant, and a leak inspection. R-22 systems cost more than R-410A systems because R-22 refrigerant is no longer manufactured and its market price is high. The exact figure depends on your system’s size, the leak location, and whether a repair is needed before the recharge. Call (725) 726-3813 for a free estimate with a written price before any work begins.
How do I know if my AC just needs a recharge or if something else is wrong?
You don’t, and guessing is expensive. Low refrigerant shares symptoms with several other problems: a failed capacitor, a clogged filter, a dirty condenser coil, or a bad blower motor can all cause warm air. That’s why we test the system before adding refrigerant. Adding refrigerant to a full system won’t fix any other problem and can damage the compressor. Our diagnostic visit will confirm the issue before you spend a dime on refrigerant.
Can you recharge my AC the same day?
Yes. Most refrigerant recharges in Las Vegas are completed same day, and we keep common refrigerants (R-410A and R-22) stocked on our service trucks. If we find a significant leak that requires a coil replacement, that part may take 1 to 3 days to arrive, but the diagnosis and recharge preparation happen the same day. A live person answers our phone 24/7, so you can schedule a visit as soon as you notice a problem.
Is it cheaper to recharge or replace my AC system?
If your system is under 10 years old and the leak is repairable, a recharge plus leak repair almost always costs less than replacement. If your system is 12 to 15 years old, uses R-22, and needs an evaporator coil replacement, the math shifts toward replacement. A $1,800 coil replacement on a 15-year-old system is often a poor investment when a new, more efficient system starts around $6,000 to $9,000 installed. We’ll give you the cost of both paths and let you decide; no pressure, just numbers.
Why does my AC keep losing refrigerant?
Refrigerant circulates in a sealed loop. It never “burns off” or “wears out.” If your system is losing refrigerant, there is a physical leak somewhere: a coil, a fitting, a valve core, or a line set. Every recharge should start with leak detection. If a company offers to “top off” your refrigerant year after year without finding and repairing the leak, they are not following EPA guidelines and they’re costing you money. Cold Harbour Heating and Air Las Vegas always locates the leak before recharging. Call (725) 726-3813 and we’ll explain what we found, in plain English, before you commit to anything.
