FAQ's

  • Why is regular generator maintenance important?

    Regular generator maintenance ensures your unit operates efficiently when you need it most. Without proper upkeep, components can degrade, leading to unexpected failures during power outages. Maintenance includes checking fuel levels, battery performance, coolant levels, and oil quality. Ignoring maintenance can lead to costly repairs or even complete system failure. Routine inspections catch small issues before they turn into major breakdowns, extending the lifespan of your generator and ensuring it runs safely and reliably.

  • How often should I service my generator?

    Most manufacturers recommend servicing your generator at least once or twice a year, but frequency depends on usage. If you rely on your generator frequently or experience extreme weather conditions, quarterly maintenance may be necessary. Regular checkups include oil and filter changes, battery tests, fuel system inspections, and load bank testing. For businesses or homes in storm-prone areas, servicing before peak seasons is crucial to avoid operational failures when power outages occur.

  • What happens during a typical generator maintenance service?

    A comprehensive maintenance service includes:

    • Oil and filter change to prevent engine wear.
    • Battery inspection and testing to ensure proper startup.
    • Coolant level check to prevent overheating.
    • Fuel system inspection to check for leaks or contamination.
    • Load bank testing to simulate a power outage and verify performance.
    • Wiring and connection checks to prevent electrical faults.

    This process ensures your generator operates at peak efficiency and prevents unexpected malfunctions.

  • Can I perform generator maintenance myself, or do I need a professional?

    While basic checks like monitoring fuel levels or inspecting visible wear can be done by the owner, professional maintenance is crucial for deep diagnostics. Certified technicians use specialized tools to assess battery voltage, coolant integrity, engine performance, and load capacity. Attempting to handle complex maintenance without expertise may lead to improper repairs, voided warranties, or undetected issues that could cause failure during an outage. Hiring a professional ensures compliance with manufacturer guidelines and long-term reliability.

  • How do I know if my generator battery needs replacing?

    Most generator batteries last between 2 to 5 years, but performance can decline due to extreme temperatures, infrequent use, or poor maintenance. Signs of battery failure include slow cranking, dim control panel lights, and inconsistent startup. Regular battery load tests during maintenance help detect weakness before failure occurs. If your generator hasn’t been used in a while, it’s important to have the battery checked since long periods of inactivity can cause it to lose charge.

  • How does fuel quality affect my generator's performance?

    Poor-quality fuel can lead to clogged injectors, carbon buildup, and engine malfunctions. Over time, stored fuel can degrade due to moisture accumulation and microbial growth, leading to sludge that clogs filters and fuel lines. Regular fuel testing and treatment, including water separation and biocide treatments, help maintain fuel integrity. If your generator runs on diesel, it’s recommended to have fuel polished periodically to remove contaminants and keep your system running smoothly.

  • Is it normal for my generator to run a self-test?

    Yes, many modern standby generators perform automatic self-tests on a weekly or monthly basis. These tests run for a few minutes to ensure readiness without generating full power output. While self-tests are useful, they don’t replace full-load tests or routine inspections. If you notice unusual sounds, error codes, or failed self-tests, it’s important to schedule a professional evaluation to identify potential issues before an actual outage occurs.

  • How do I prepare my generator for storm season?

    Before storm season, schedule a professional inspection to check fuel levels, battery life, and wiring integrity. Run a load test to ensure the generator can handle demand. Stock up on extra oil, filters, and fuel stabilizers. Clear debris around the generator for ventilation, and secure it against high winds. If you rely on propane, check that supply levels are sufficient. Proper preparation minimizes the risk of failure when power is needed most.

  • Can a generator be too large or too small for my home or business?

    Yes, an oversized generator wastes fuel and increases maintenance costs, while an undersized unit won’t provide enough power during an outage. Proper generator sizing is based on the total electrical load required, factoring in startup surges for appliances. A professional assessment helps determine the right generator capacity, ensuring efficiency and reliability without excessive operational costs.

  • Can cold weather affect my generator’s performance?

    Yes, extreme cold can cause battery failure, thickened oil, and fuel gelling (in diesel units). To ensure winter readiness:

    • Use cold-weather kits, including battery warmers and engine block heaters.
    • Keep the generator enclosure insulated but well-ventilated.
    • Perform extra fuel checks to prevent condensation buildup.
    • Test-start your generator periodically in winter to ensure it’s operational when needed.
