Essential Maintenance Tasks and Procedures

Our comprehensive generator maintenance program at First Choice Plumbing, Heating, Air Conditioning & Electrical encompasses multiple critical procedures performed at specific intervals. Monthly inspections include checking oil levels, coolant levels, and battery condition while ensuring the unit runs properly during its automatic exercise cycle. We examine the entire fuel system for leaks, test the battery charging rate, and verify that block heaters function correctly during colder months. These routine checks help identify potential issues before they develop into costly failures, allowing us to address minor problems during scheduled maintenance rather than emergency situations.

Annual maintenance requires more intensive procedures that our certified technicians perform meticulously. We change the oil and filters, replace spark plugs in gas-powered units, flush and refill the cooling system with fresh coolant, and clean or replace air filters depending on environmental conditions. Load bank testing represents one of the most crucial annual procedures, where we simulate full electrical loads to verify your generator can handle your home’s power demands. We also update firmware in digital controllers, calibrate automatic transfer switches, and test all safety systems including low oil pressure shutdowns and high temperature alarms. This comprehensive approach ensures every component functions within manufacturer specifications.

Common Generator Problems We Prevent

Through our maintenance programs, we prevent numerous issues that commonly plague neglected generators throughout Garfield, Hackensack, Hasbrough, Lodi, Passaic, Saddlebrook, Edison Township, Hasbrouck Heights, Highland Park, and Woodbridge, NJ. Battery failure remains the leading cause of generator startup failures, as batteries naturally discharge over time and suffer from sulfation when left in partially charged states. We test battery specific gravity, clean terminals to prevent corrosion buildup, and replace batteries showing signs of deterioration before they fail. Fuel system problems represent another major concern, particularly with diesel generators where fuel contamination and algae growth can clog filters and injectors. Our maintenance includes fuel polishing services, water removal from tanks, and fuel stabilizer applications that prevent degradation during long storage periods.

Cooling system failures can cause catastrophic engine damage if left unaddressed. We inspect radiator fins for debris accumulation, test coolant freeze protection levels, and check for internal corrosion that weakens system components. Belt tension and condition receive careful attention since loose or worn belts cause alternator charging problems and cooling system inefficiency. Our technicians also address exhaust system integrity, checking for carbon buildup, loose connections, and corrosion that could allow dangerous gases to escape into living spaces.
