Maintenance for Residential & Commercial Systems
A standby generator is only as reliable as its maintenance. At Jacinto Generators, we offer comprehensive preventative maintenance plans designed to keep your Generac generator operating safely, efficiently, and ready when you need it most.
View Our Maintenance Options
Our maintenance programs are available for both residential and commercial systems and are performed by trained technicians with deep knowledge of Generac equipment. All plans include Automatic Transfer Switch (ATS) inspection and testing, ensuring your system activates properly during an outage.
Routine Service for Ongoing Reliability
Our Minor Preventative Maintenance plan is ideal for generators that are lightly used or newer systems that require routine inspection and testing.
This service includes a thorough inspection and operational check of all major systems, including:
-
Engine oil level and condition checks
-
Cooling system inspection (coolant levels, hoses, belts, fans, block heaters)
-
Fuel system inspection (diesel or gaseous systems)
-
Air intake and exhaust inspection
-
Battery testing, charging system checks, and electrical connections
-
Engine start-up, run testing, and performance readings
-
Visual inspection for leaks, wear, corrosion, or abnormal conditions
-
Recording of run hours, voltages, frequencies, and temperatures
This plan helps ensure your generator remains in proper working order and flags any developing concerns early.
-
Comprehensive Service for Maximum Protection
Our Major Preventative Maintenance plan is a more in-depth service recommended for higher-use systems, older generators, or critical power applications.
In addition to all Minor Maintenance items, this plan includes:
-
Engine oil and filter replacement using manufacturer-approved oil
-
Fuel filter replacement (diesel systems)
-
Coolant system servicing, including coolant element replacement
-
More detailed mechanical and electrical inspections
-
Enhanced diagnostics and performance verification
This plan is designed to reduce the risk of unexpected failures, improve efficiency, and support long-term generator health.
-
Every maintenance visit includes full Automatic Transfer Switch inspection and testing, which is critical to ensuring your generator actually supplies power during an outage.
ATS maintenance includes:
-
Inspection of switch components, wiring, and safety guards
-
Review of system history and alarm events (if equipped)
-
Testing and recording of all time delay settings
-
Verification of voltage pickup and dropout settings for normal and emergency power
-
Visual inspection of indicators, cabling, and enclosure condition
Without a properly functioning ATS, even a well-maintained generator may fail to activate — which is why this service is always included.
