Commercial Generator Service Agreements

Two visits per year for facilities that require higher reliability. Essential for hospitals, data centers, and manufacturing operations where generator failure is not an option.

Major Service Visit:

• Inspect essential generator parts
• Replace oil, filters, and spark plugs
• Inspect and adjust high wear items, belts, and critical components
• Verify operational output and perform safety shutdown check
• Inspect ATS (if accessible)

Minor Service Visit:

• Visual inspection of generator and enclosure
• Check fluid levels (oil, coolant)
• Inspect battery and connections
• Verify exercise schedule and review fault history
• Inspect ATS (if accessible)

Real-time monitoring of your generator status, fault codes, and exercise cycles. Our team is alerted immediately to any issues and can often diagnose problems remotely before dispatching a technician.

Load bank testing verifies that your generator can handle its full rated capacity under real-world conditions. Regular load banking is required for NFPA 110 compliance and helps prevent wet stacking -- a condition where unburned fuel builds up in the exhaust system due to prolonged light-load operation. This is especially important for diesel generators that rarely run at full load.

Diesel fuel degrades over time. Water contamination, microbial growth, and oxidation can all compromise fuel quality and cause your generator to fail when you need it most. Our fuel testing service identifies problems before they lead to costly repairs or generator failure during an outage.

Powers Guaranteed Services has a fleet of trailer-mounted diesel rental generators available for use throughout New England. Rental generators can be arranged on a weekly, monthly, or longer-term basis. Whether you need temporary power during a scheduled maintenance window, a construction project, or an emergency, we have options to keep your facility running.

When your generator fails unexpectedly, every minute counts. Our emergency response team provides rapid dispatch and one-trip diagnosis whenever possible. Commercial service agreement holders receive priority scheduling during widespread outage events.

For facilities with multiple generators or specialized requirements, we design custom maintenance programs tailored to your operational needs and budget.
