A commercial AC failure in Las Vegas summer is not a comfort issue. It is an operations issue. Employees cannot work, customers do not stay, and perishables, equipment, or inventory may be at risk depending on your business type.
Pure Plumbing & Air has been handling commercial AC repairs across the Las Vegas valley since 2013. Our licensed technicians dispatch same-day in most cases, carry the parts most commercial repairs need, and give you a firm price before any work begins.
Commercial AC repair means identifying exactly what failed and fixing it correctly the first time. We diagnose and repair commercial AC equipment across all major configurations and brands, including:
Rooftop packaged units (RTUs)
Split-system commercial AC
Multi-zone commercial systems
Ductless commercial mini-splits
Packaged terminal air conditioners (PTACs)
What We Check Before We Quote Anything
We do not guess. Readings determine the recommendation. Before we suggest a repair, our technicians run a full system evaluation:
Electrical diagnostics: capacitor health, contactor condition, compressor and fan motor amp draw, control board function, and start component testing. We check for loose connections and heat discoloration at terminals, which are more common on rooftop units with direct sun exposure.
Refrigerant integrity: leak detection, superheat and subcool readings in the current operating mode, coil condition, and line set inspection. On any sealed-system work, we pull a deep vacuum and verify with a micron gauge before charging. We record charge readings, airflow, and temperature split after every repair.
Economizer operation and controls: economizer damper function, actuator condition, and controls integration checked on units where economizers are installed. Economizer faults are a common source of comfort complaints and energy waste on Las Vegas commercial RTUs.
Airflow and static pressure: blower performance, filter condition, temperature split across supply and return, and duct leakage indicators. High Las Vegas dust loads mean filters and coils restrict airflow faster than standard intervals assume.
Condenser section: fan motor operation, coil condition, and heat rejection capacity confirmed. Condenser fan failures on rooftop units are more frequent here due to direct sun exposure accelerating motor wear.
Controls and thermostat: confirmed setpoints, staging, zone operation where applicable, and building management system integration where relevant
Post-repair verification: system tested under operating conditions and performance readings documented before we close the job. Your team gets a record of what was found and what was completed.
Capacitor failures: the most frequent commercial call we get, particularly mid-summer after months of continuous operation. A failing capacitor causes the compressor or fan motor to struggle starting or stop working entirely.
Contactor failure: worn or pitted contactors prevent the outdoor unit from starting. Common after long cooling seasons and more frequent on rooftop units with high heat exposure.
Condenser fan motor failure: outdoor fan stops spinning, causing the system to overheat and trip on high pressure. Rooftop units in Las Vegas see accelerated motor wear from direct sun and heat soak.
Refrigerant leaks: reduced cooling capacity, longer run times, and eventually compressor damage if left unaddressed. We locate the leak, repair it, and recharge to spec.
Economizer faults: stuck dampers, failed actuators, and controls issues cause outside air to enter at the wrong volume, driving up cooling load and energy costs. Common on older RTUs that have not had regular maintenance.
Coil restrictions: dirty condenser or evaporator coils from dust buildup reduce heat transfer and force the system to work harder. Las Vegas dust loads make this more frequent than in most markets.
Blower motor and belt issues: reduced airflow, unusual noise, or no airflow from the indoor section. Belt-driven units require periodic tension and wear checks.
Control board and thermostat faults: incorrect staging, failed zone controls, or no call for cooling from the building management system.
Compressor issues: on systems where repair still makes financial sense, we assess compressor condition and give you honest numbers on repair versus replacement.
Residential AC Repair
If you need AC repair for a home rather than a commercial property, our Residential AC Repair page covers diagnosis and repair for residential systems.

AC Maintenance
Most commercial AC breakdowns trace back to deferred maintenance. Planned service catches the kind of wear that leads to repair calls before it becomes a breakdown and keeps equipment running at rated efficiency through the cooling season.

AC Installation
If your system is past the point where repair makes financial sense, replacement is often the better path. We install all major commercial brands and handle load calculations, permitting, and commissioning as part of every job.

Signs Your Commercial AC Needs Repair
Do not wait for a complete failure. In Las Vegas summer heat, a struggling system can go from underperforming to completely down in a short window. Call us if you notice:
The system is running but not cooling the space to setpoint
Airflow from supply diffusers feels weak or uneven across zones
The outdoor unit is running but the indoor section is not delivering cold air
The system is short-cycling, turning on and off frequently without holding temperature
Unusual noises from the rooftop unit or indoor air handler including grinding, banging, or rattling
Energy bills jumped without a change in occupancy or usage
Certain zones or areas of the building stay significantly warmer than others
The system will not start at all
Occupants are complaining about comfort despite the thermostat being set correctly
On commercial properties, a system that is struggling but not completely down typically has a compounding effect. Short-cycling causes additional wear. Reduced airflow from dirty coils increases run time and energy cost. Catching the issue early is almost always less expensive than waiting for a complete failure.
Commercial vs. Residential AC Repair
Commercial AC repair differs from residential work in several ways that affect how we approach every job:
Equipment type. Most Las Vegas commercial properties use rooftop packaged units rather than the split systems common in residential construction. RTUs combine the condenser, evaporator, and air handler in a single rooftop cabinet, which requires different diagnostic access and component handling than a residential split system.
Scale and zones. Commercial systems often serve multiple zones with separate controls, thermostats, or building management system integration. A comfort complaint in one area of a building may trace to a zone control issue rather than an equipment failure.
Downtime cost. A commercial AC failure has a direct business cost that a residential failure does not. We prioritize commercial calls accordingly and work around your operating hours where possible.
Documentation. Property managers and business owners often need documented service records for maintenance files, lease compliance, or warranty purposes. We provide written documentation of findings and completed work on every commercial job.

What to Expect When You Call
Dispatch: We confirm your property address and system type and get the right technician headed your way. Same-day dispatch available for most Las Vegas valley locations.
Assessment: Full system evaluation before we recommend anything. We diagnose the root cause, not just the symptom that triggered the call.
Options and pricing: We explain what we found, what it costs to fix, and what the tradeoffs are. No work starts until you approve.
Work: Completed with minimal disruption to your operations. We coordinate roof access and scheduling around your business hours where needed.
Verification and documentation: System tested under operating conditions before we close the job. We document findings and completed work so your team has a record for maintenance files.
A few realities specific to Las Vegas commercial properties that affect how we approach every repair call:
RTU dominance. Rooftop packaged units are the standard configuration across strip mall, retail, and single-story office construction throughout the valley. These units take direct year-round sun exposure that accelerates wear on capacitors, contactors, and heat exchanger components faster than ground-level equipment.
Dust loads. Clark County dust levels are significantly higher than most U.S. markets. Condenser and evaporator coils accumulate debris faster than standard service intervals assume, reducing heat transfer efficiency and increasing run time and energy cost.
Season length. Las Vegas commercial cooling season runs roughly April through October. Seven months of near-continuous operation means components here log more annual hours than systems in most of the country.
Heat soak. Rooftop equipment sits in one of the hottest surface environments in the country during peak summer. Ambient temperatures around rooftop units frequently exceed the conditions used in standard equipment ratings.
The U.S. Department of Energy notes that regular maintenance and timely repairs are the most effective way to maintain commercial cooling efficiency and extend equipment life, both of which have direct operating cost implications for Las Vegas businesses running systems in demanding conditions.

Cost depends on the system type, the component that failed, and the scope of the repair. Minor repairs like a capacitor or contactor replacement typically run between $200 and $500. Larger repairs involving compressors, economizers, or control boards run higher. We give you a firm price after the diagnostic so you know exactly what to expect before we start.
Yes. Same-day dispatch is available for most Las Vegas valley locations. We also provide 24/7 emergency service for situations that cannot wait, including nights, weekends, and holidays.
Direct year-round sun exposure accelerates wear on capacitors, contactors, and fan motors faster than ground-level equipment. High Las Vegas dust loads accumulate on coils and filters more quickly than in most markets, reducing efficiency and increasing component strain between service visits. Regular maintenance is the most effective way to extend RTU life and reduce emergency repair frequency.
Yes. We schedule non-emergency repairs and planned maintenance around your operating hours, including evenings and weekends. Emergency repairs are available 24/7 regardless of day or time.
If the system is under 10 to 12 years old and the repair is a single issue costing well under half the replacement cost, repair usually makes sense. If it is older, has needed multiple major repairs recently, or consistently fails to maintain comfortable temperatures during peak Las Vegas summer heat, replacement tends to make more financial sense. We give you the numbers for both options before you decide.
We repair Lennox, Trane, Carrier, Goodman, Rheem, American Standard, Daikin, and other major commercial brands. Our technicians are trained on both older equipment and current models across all major commercial system types.
Zone-specific comfort complaints can point to a zone control fault, a damper issue, a duct leak in that branch, or a coil restriction on the unit serving that zone. It can also indicate an equipment sizing issue if the complaint is consistent across seasons. We diagnose to the root cause rather than assuming equipment failure when a single zone is affected.
At minimum twice a year for Las Vegas commercial properties. One visit before peak cooling season in spring and one after the cooling season in fall. Las Vegas commercial systems log more annual runtime hours than systems in most markets, and high dust loads accelerate coil and filter buildup faster than standard service intervals account for. Regular maintenance is the most cost-effective way to reduce emergency repair frequency and extend equipment life.
