When your AC goes down in Las Vegas, it's not a minor inconvenience. It's urgent. Pure Plumbing & Air has been helping homeowners across the valley get their cooling systems back up since 2013. Our licensed technicians arrive same-day, carry the parts most repairs need, and tell you the price before any work begins. If your unit is struggling, making noise, or stopped working altogether, we can help.
AC repair means diagnosing what failed and fixing it correctly the first time. That sounds simple, but the actual work requires checking the full system, not just the part that seems obvious.
A lot of Las Vegas AC problems trace back to something upstream:
a weak capacitor that’s been struggling for months
restricted airflow from a clogged filter
or refrigerant that’s been slowly leaking since last season
Monsoon humidity spikes in late summer can trigger coil icing and condensate issues on systems that handled dry heat just fine weeks before. Dust loads here are significantly higher than most markets, which is why filters and coils get dirty faster than manufacturer guidelines account for.
Fast Diagnosis: What We Measure Before We Quote
Before we recommend anything, our technicians run through a full evaluation. We don’t guess. Readings determine the recommendation.
Electrical diagnostics: capacitor health, contactor condition, amp draw on the compressor and fan motors, thermostat signal verification, and start component testing.
Airflow and static pressure: filter restriction, blower performance, temperature split testing across supply and return, and duct leakage indicators.
Refrigerant integrity: leak detection, superheat and subcool readings, coil condition, and line-set inspection.
Drain and condensate: condensate line flow, float switch operation, and pan condition. Clogs here are one of the most common causes of system shutdowns in Las Vegas homes.
Post-repair verification: once the repair is complete, we confirm delta-T targets are met, check cycling behavior, and take supply and return readings before we consider the job done.

Common Repairs We Handle in Las Vegas
Capacitor failures are among the most frequent calls we get, especially after a long cooling season. Refrigerant leaks, failed contactors, blower motor issues, and clogged condensate lines round out the majority of repair calls.
Dust-related coil restriction and blower strain are also common here. Las Vegas dust loads accelerate buildup on evaporator coils and blower wheels, which reduces airflow, drives up energy use, and pushes components toward early failure.
We also handle thermostat faults, control board failures, and compressor issues on systems where repair still makes financial sense.
AC Troubleshooting
Not every call starts with a clear symptom. Sometimes the system runs but something just feels off. Output is weaker than it used to be, one room never catches up, or the unit cycles in a pattern it did not used to follow. We run diagnostics on the full system, electrical, airflow, refrigerant, and controls, and pin down exactly what changed. Troubleshooting is how we keep a small quirk from becoming a big repair bill.
AC Capacitor Replacement
Capacitors are one of the most common failure points in Las Vegas AC systems. They store the electrical charge that starts the compressor and fan motors, and the sustained heat here wears them down faster than in cooler climates. A failing capacitor usually shows up as a system that hesitates on startup, hums without engaging, or shuts off within seconds of turning on. We test capacitors on every diagnostic call and carry replacements on every truck.
Compressor Replacement
When a compressor fails, the entire cooling cycle stops. In Las Vegas, where systems log seven months of near-continuous runtime, compressor failures are more common than in most markets. We diagnose the root cause, give you honest numbers on repair vs. full unit replacement, and handle the full sealed-system process if a new compressor is the right call.

Residential AC Repair
If you own or rent a home in Las Vegas and your AC isn’t keeping up, this page covers repairs specific to residential systems. We work on all major brands and can usually get to you the same day you call.
See our Residential AC Repair page.
Commercial AC Repair
Businesses have different demands than homes. A failing AC in a restaurant, office, or retail space can affect customers, employees, and equipment. We handle commercial repairs with the same urgency we bring to residential calls, and we work around your hours when possible.
See our Commercial AC Repair page.
AC Tune-Up
If your system is running but not as efficiently as it used to, the issue may not require a repair at all. A tune-up catches small problems before they become expensive failures and keeps your system running at full capacity through the hottest months.
Want to prevent the next breakdown? Take a look at our AC Tune-Up page.
AC Installation
Sometimes a repair isn’t worth it. If your system is more than 10 to 15 years old and repairs are adding up, replacing the unit often makes more financial sense. We’ll be straightforward with you about which option fits your situation.

HVAC Maintenance
Staying ahead of repairs starts with routine maintenance. If your system hasn’t been serviced in a while, a maintenance visit can catch wear before it turns into a breakdown, especially heading into peak cooling season.

Freon Recharge
If the diagnosis comes back as low refrigerant, a recharge gets the system cooling again. But low Freon does not happen on its own. It means something is leaking. Every recharge from Pure starts with a leak check so the fix actually lasts and you are not paying for the same refrigerant twice a few weeks later.
Need a refrigerant recharge? See our Freon Recharge page.
AC Leak Repair
When a leak check confirms refrigerant is escaping, the next step is finding the exact point and sealing it. Coil joints, service valves, and brazed connections are the usual suspects in Las Vegas systems that have been running hard for years. We locate it, fix it, and recharge to spec so the system holds.

Emergency AC Repair (When It Can’t Wait)
Las Vegas heat doesn’t follow business hours. When your system shuts down at midnight in August, or stops cooling on a Saturday afternoon, we’re available. Our dispatch team runs 24 hours a day, 7 days a week, including holidays.
While you wait for your technician, a few things help: set your thermostat to fan-only mode to keep air circulating, check that your breaker hasn’t tripped, and swap your filter if it’s visibly clogged. These steps won’t fix the problem, but they can keep the house more bearable until we arrive.
Here’s what to expect once you book:
Dispatch: We confirm your location and get a technician headed your way, same-day in most cases.
Diagnostics: Full system evaluation before we quote anything. No guessing.
Options: We explain what’s wrong, what it costs to fix, and whether repair or replacement makes more sense.
Repair: Work starts only after you approve the price. No surprises on the invoice.
Verification: We test the system, confirm it’s cooling correctly, and check performance readings before we leave.
Signs You Need AC Repair (Before It Turns Into a Bigger Failure)
Some problems announce themselves. Others show up quietly in your energy bill or in one room that never quite cools down. Las Vegas systems run hard. Long runtimes, intense heat soak from rooftops and attics, and heavy dust loads all push components toward failure faster than in moderate climates. Catching a problem early usually means a simpler, less expensive fix.
Call soon if you notice:
Your AC is blowing warm or room-temperature air
The system cycles on and off every few minutes without fully cooling the space
You hear grinding, banging, rattling, or squealing from the indoor or outdoor unit
Energy bills jumped without a change in how you use the AC
Ice is forming on the refrigerant lines or indoor coil
Water is pooling around the indoor air handler
Certain rooms stay significantly warmer than others
The system won’t turn on at all
The Department of Energy notes that dirty, clogged filters restrict airflow and reduce efficiency. Regular upkeep prevents performance drop and higher energy use. If any of these signs are familiar, getting a technician out sooner prevents a manageable repair from becoming a full replacement.
Repair vs. Replace (How We Recommend the Right Option)
We get this question on almost every call where a system is older or has had multiple issues. Our answer is always based on the actual numbers, not on what’s easier to sell.
Not every aging system needs to be replaced. In many cases, a single targeted repair gets you back to full performance at a fraction of the cost of new equipment. Repair is almost always the right call when:
The system is under 10 years old. It’s a single issue, not a pattern.
The system has been maintained.
The repair cost is well under half the price of a new unit
In these cases, repair is almost always the right call.
A capacitor, contactor, or refrigerant recharge on an otherwise healthy system is a straightforward fix with years of useful life left in the equipment.
Replacement is a bigger decision, but in some situations it’s clearly the better use of your money. The following conditions usually point toward a new system rather than another round of repairs. If more than one of these applies, replacement is likely the stronger option:
The system is past 12 to 15 years old.
You’ve had multiple major repairs in the last couple of seasons.
The compressor has failed and the repair cost approaches the price of a new unit.
The evaporator coil has a refrigerant leak and coil replacement pricing puts you close to new-system territory.
The system still uses R-22 refrigerant, which is no longer manufactured and increasingly expensive to source.
Refrigerant loss keeps recurring, pointing to a chronic leak that repairs haven’t resolved.
We lay it out honestly. What’s wrong, what it costs to fix, and whether that money is better spent toward something new.

If your system is under 10 years old and the repair cost is less than half the cost of a new unit, repair usually makes sense. If it’s 12 to 15 years old, needs frequent fixes, or still can’t keep your Las Vegas home comfortable at peak heat, replacement tends to make more financial sense. We’ll go over both options with actual numbers and let you decide.
Short cycling (when the unit kicks on and off too quickly) is most often caused by an oversized system, a dirty air filter, low refrigerant, or a thermostat in a poor location. We confirm the actual cause through amp draw readings, static pressure checks, and airflow testing, not guesswork. Short cycling puts extra wear on the compressor, so it’s worth diagnosing quickly
It can cause several. Las Vegas dust loads are higher than most markets, which means filters clog faster than manufacturer replacement schedules account for. A restricted filter reduces airflow, forces the blower to work harder, can cause the evaporator coil to ice over, and drives up energy bills. If your system is struggling and you haven’t checked the filter recently, that’s always the first thing to look at.
Call us. We provide 24/7 emergency AC repair across Las Vegas and the surrounding area. While you wait, set your thermostat to fan-only mode to keep air moving, check your breaker panel, and keep interior doors open to equalize temperatures between rooms. In summer heat, an overnight breakdown can become a safety issue quickly. If your system has a recurring issue, it may also be time to look at an HVAC maintenance plan to prevent the next one.
