Commercial Generator Repair & Maintenance
Commercial & Industrial Generator Repair and Maintenance in Nevada
Keeping Nevada’s Businesses Powered Without Interruption
For Nevada businesses, reliable power isn’t just convenient—it’s critical. From manufacturing plants and hospitals to casinos and data centers, downtime can mean lost revenue, safety risks, or operational shutdowns. Happy Hals Generators provides comprehensive commercial and industrial generator repair and maintenance services across Nevada, ensuring your systems stay reliable, efficient, and compliant with all local standards.
Our certified technicians work with a wide range of generator systems—diesel, natural gas, and propane—across all major brands, including Generac, Cummins, Kohler, and CAT. Whether your unit supports a small retail store or powers a multi-building complex, we keep it running at full capacity so your operations never skip a beat.
Comprehensive Commercial Generator Repair
When a commercial generator fails, every minute of downtime can have costly consequences. Our emergency and scheduled repair services are built to minimize interruption and restore power fast.
We begin every repair with a full system diagnostic and performance evaluation, using advanced testing tools to identify faults in electrical, mechanical, or fuel systems. Once the issue is located, our technicians perform targeted repairs using OEM-grade parts and manufacturer-approved procedures.
Typical commercial generator repairs include:
Electrical Component Repair
We service control panels, circuit boards, wiring harnesses, sensors, and voltage regulators to correct power inconsistencies or shutdown errors.
Mechanical and Engine Service
From injector and fuel pump replacements to alternator repairs, we restore optimal power output and fuel efficiency. We also handle cooling system issues, oil leaks, and worn engine components.
Transfer Switch and Synchronization Repair
We repair Automatic Transfer Switches (ATS) and synchronization controls to ensure seamless transition between generator and utility power, especially for facilities that require continuous uptime.
Our repair fleet is equipped with the most common parts and diagnostic tools, allowing us to resolve most issues in a single visit.
Preventive Maintenance Programs for Industrial Generators
The best way to prevent unexpected outages is through consistent, professional maintenance. Happy Hals Generators offers custom maintenance programs tailored to commercial and industrial clients throughout Nevada.
Each maintenance plan is designed around the unique load demands, runtime, and operating environment of your facility. Our scheduled visits keep your generator performing efficiently and in compliance with OSHA and NFPA 110 standards for emergency power systems.
Our industrial maintenance includes:
Oil, Filter, and Coolant Service
We replace oil, fuel, and air filters at factory-recommended intervals and flush cooling systems to prevent overheating during long runs.
Load Bank Testing
We simulate full electrical loads to ensure your generator can deliver rated power under real conditions. Load testing prevents “wet stacking,” a buildup of unburned fuel that reduces efficiency.
Fuel System Maintenance
We inspect tanks, lines, and injectors for leaks, sediment, or microbial growth, and offer fuel polishing to keep diesel clean and stable.
Battery and Electrical Checks
We test batteries, chargers, and cabling to guarantee reliable starts during blackouts.
Our service documentation includes detailed inspection reports and test results, giving you a clear view of your generator’s condition and compliance status.
