Our certified technicians understand that commercial generators are critical infrastructure investments that require specialized expertise to maintain, repair, and install properly.
Our Commercial Generator Services
OneStop Pro offers complete commercial generator solutions designed to keep your business operational during power outages. Our team works with all major commercial generator brands and sizes, from small office backup units to large industrial standby systems.
Commercial Generator Installation
We handle every aspect of commercial generator installation, from initial site assessment and load calculations to final commissioning and testing. Our installation process includes proper electrical connections, gas line installation or diesel fuel system setup, concrete pad preparation, and ensuring all local codes and regulations are met. We work closely with local utility companies and obtain all necessary permits to ensure your installation is compliant and safe.
Preventive Maintenance Programs
Regular maintenance is crucial for commercial generators that may sit idle for months between uses. Our comprehensive maintenance programs include monthly or quarterly service visits where we test all systems, change filters and fluids, inspect belts and connections, and run full load tests. We maintain detailed service records and provide reports after each visit, helping you track your generator’s performance and plan for any needed repairs or upgrades.
Emergency Generator Repair
Generator problems never happen at convenient times. That’s why we offer 24/7 emergency repair services for commercial customers throughout the Wheaton area. Our service trucks are fully stocked with common replacement parts and diagnostic equipment, allowing us to resolve many issues on the first visit. We understand that every minute of downtime costs your business money, so we prioritize rapid response and effective solutions.
Load Bank Testing
Load bank testing is essential for verifying that your commercial generator can handle its rated capacity when called upon. We provide portable load bank testing services that simulate real-world electrical loads, allowing us to identify potential issues before they cause failures during actual power outages. This testing is often required by insurance companies and building codes for critical facilities.
Transfer Switch Services
The transfer switch is the brain of your generator system, automatically starting your generator and switching power sources during outages. We service, repair, and install both manual and automatic transfer switches for commercial applications. Our technicians are experienced with all major transfer switch manufacturers and can upgrade older manual systems to modern automatic units for improved reliability and convenience.

Frequently Asked Questions
How often should commercial generators be serviced?
Commercial generators should be serviced monthly at minimum, with more comprehensive quarterly maintenance. The frequency depends on your generator’s size, usage, and criticality to your operations. Facilities like hospitals or data centers may require weekly testing and monthly maintenance, while office buildings might operate on quarterly schedules. Our technicians will recommend the appropriate service interval based on your specific equipment and needs.
What size commercial generator do I need for my business?
Generator sizing depends on your essential electrical loads during an outage. We perform detailed load calculations considering lighting, HVAC systems, computers, machinery, and other critical equipment. Factors like starting currents for motors and future expansion plans also influence sizing decisions. Our team will conduct an on-site assessment and provide recommendations for the most cost-effective solution that meets your power requirements.
How long does commercial generator installation take?
Installation timelines vary based on generator size and site complexity, but most commercial installations take 2-5 business days. Larger systems or those requiring extensive electrical work may take longer. The process includes site preparation, generator placement, electrical connections, fuel system installation, and thorough testing. We’ll provide a detailed timeline during the planning phase and coordinate with your business to minimize disruption.
What maintenance records are required for commercial generators?
Most local codes and insurance policies require documented maintenance records for commercial generators. We maintain comprehensive service logs including test results, fluid changes, part replacements, and performance data. These records are essential for warranty claims, insurance requirements, and regulatory compliance. We provide detailed reports after each service visit and can supply historical data when needed for inspections or audits.
