Generator Maintenance
Preventative Maintenance for your generator
At Abtech Electrical Services, preventative maintenance for your generator is about ensuring reliable backup power before you ever need it. Just like routine care for a vehicle, a generator requires scheduled check-ups — including inspection of fluid levels, filters, electrical connections, battery condition, and control systems — to operate safely and efficiently when a power outage strikes. Regular maintenance helps extend the life of your unit, prevent costly repairs, and maximize performance by identifying small issues before they become major problems. Our trained technicians perform comprehensive evaluations tailored to your generator’s needs so that whether it’s for your home or business, your investment stays protected and ready to deliver power when it matters most.
Starting With the Engine
Abtech Electrical Services emphasizes preventative generator maintenance to protect the engine that powers your backup system. Because generators run infrequently, moisture can accumulate inside the engine and compromise lubrication if left unaddressed. Annual oil changes and routine load testing performed by our technicians help prevent condensation issues and ensure your generator is ready when you need it most.
Changing the Oil
Abtech Electrical Services uses only full synthetic oil when servicing generators to better protect the engine from moisture buildup. Unlike conventional oils that can mix with water and reduce performance, synthetic oil keeps moisture separated so it can dissipate during load testing or routine oil changes. This approach helps ensure smoother operation and long-term reliability.
Changing the Air Filter
At Abtech Electrical Services, we replace generator air filters annually to prevent hidden moisture buildup that can restrict airflow. Even when an air filter appears clean, trapped moisture can reduce engine efficiency and overall performance. Proper airflow is essential to keeping your generator running at peak capacity.
Changing the Spark Plugs
At Abtech Electrical Services, we replace spark plugs annually because natural gas engines can wear them down faster than many homeowners expect. Acidity and impurities in natural gas can cause corrosion that leads to misfires over time. Routine replacement helps maintain dependable startup and consistent generator performance.
Adjusting the Valves
Generator engines rely on precise valve clearances, and normal wear can cause valves to tighten and affect starting and performance. Manufacturers recommend periodic valve adjustments, which Abtech Electrical Services includes as part of routine maintenance. Keeping valves properly adjusted helps ensure smooth operation and peak generator performance year after year.
Checking the Frequency
After engine service, Abtech Electrical Services verifies and adjusts generator frequency to ensure it delivers the proper 60 Hz electrical output. Incorrect frequency indicates improper engine speed and can damage electrical systems or connected equipment. Annual testing and adjustment help keep your generator operating safely and within manufacturer specifications.
The Generator
A generator’s electrical system includes the rotor, stator, voltage regulator, and related components that are constantly exposed to environmental conditions. Abtech Electrical Services thoroughly inspects these parts, tightens all electrical connections, and protects wire terminations to prevent corrosion and performance issues. This detailed attention helps ensure reliable power delivery and long-term system durability.
Checking the Voltage
In addition to frequency, Abtech Electrical Services tests and adjusts generator voltage to ensure safe, clean power delivery. Standard residential voltage is 120/240 volts, and deviations can damage sensitive electronics and household systems. Proper voltage regulation helps protect appliances, control boards, and other essential electrical components.
Checking the Control Board
Your generator’s digital control board relies on a stable 12-volt power supply to manage system operation. While settings typically remain unchanged after installation, Abtech Electrical Services verifies programming and system function during annual maintenance. This ensures proper operation and allows for updates if needed.
Checking the Battery
Generator batteries are constantly charging and exposed to the elements, which can lead to corrosion, overheating, and premature failure. Abtech Electrical Services load-tests batteries during annual maintenance, cleans terminals, and helps prevent damage to sensitive components like the control board. Proactive battery care and timely replacement support reliable generator operation and help avoid costly repairs.
Checking the Wiring
A generator system contains extensive wiring between the unit, transfer switch, and electrical panel. Over time, connections can loosen or corrode, leading to performance and safety issues if left unchecked. Abtech Electrical Services inspects and tightens all wiring annually to help ensure safe, reliable power transfer.
Load Testing
Simply starting a generator does not confirm it will perform properly during a power outage. Abtech Electrical Services conducts full load testing by simulating a utility failure and transferring power to and from the generator. This process verifies that the system operates correctly under real-world conditions.
Protecting the Housing
The generator’s exterior— including the housing, vents, and locks — plays a critical role in protecting internal components. Without routine care, corrosion and rust can lead to water intrusion and restricted access to the unit. Abtech Electrical Services maintains these exterior components during annual service to help extend your generator’s lifespan and ensure dependable operation.
