Generators typically need full service annually or every 200-500 hours of operation (whichever comes first). We also recommend weekly visual checks and monthly exercise runs. Our tailored plans can include breaker testing, fuel tank cleaning, engine maintenance maintenance, and more to prevent issues.

A standard visit covers fluid checks (oil, coolant, fuel), filter inspections/replacements, battery testing, visual inspections for leaks or wear, control panel inspection, and system performance verification. All planned generator services can be tailored to specific customer needs.

Contaminants like water, sludge, and sediment can clog filters, damage injectors, and cause failures during outages. Regular cleaning removes these issues, restores clean fuel flow, and extends engine life, especially critical for standby systems.

Yes! We are experienced with Cummins, Onan, Caterpillar (Cat), MTU, Kohler, Generac, Baldor, Briggs & Stratton, Aggreko, and many others. Our technicians handle diagnostics, repairs, upgrades, and maintenance for diesel, natural gas, and propane units.

Breaker testing verifies trip times, insulation, contact resistance, and fault handling under simulated conditions. Helps to ensure your generator and electrical system will protect equipment and personnel during overloads or faults, meeting safety and compliance standards.

Signs include low coolant levels, overheating during tests, discolored or contaminated coolant, or worn hoses/belts. We offer tiered coolant service (Level 1–3) to replace components, flush the system, and prevent engine damage from corrosion or freezing.
