Generator Maintenance Gaps Identified by Long Island Power Systems

The Real Reason Your Standby Generator Won’t Start During a Storm

Southampton, United States – June 30, 2026 / Long Island Power Systems LLC /

Long Island, New York, June 30, 2026 – Long Island Power Systems identifies preventive maintenance gaps as the primary cause of generator failure during severe weather outages, citing field service data showing that most standby power system failures are preventable through pre-storm seasonal inspection protocols.

The update reflects recurring service findings from field technicians who report that many generator failures occur due to overlooked maintenance issues rather than equipment defects. These findings are consistent across both residential and commercial standby systems, including units that rely on routine servicing from a professional generator maintenance company.

Generator Performance Issues Identified in the Field

Service teams at Long Island Power Systems report that standby generators often fail during outages after long periods of inactivity without proper servicing. These failures typically appear during storms when systems are under the highest demand.

Mike McNeil, Owner of Long Island Power Systems, emphasized the importance of proper preparation ahead of storm season, stating: “Most generator failures we see during outages are preventable with proper maintenance, full system testing, and attention to critical components like the transfer switch.”

Common Causes of Generator Startup Failure

Generators rely on multiple systems working together to start and operate correctly. When one component fails, the entire system can shut down or fail to start.

Key Mechanical and Electrical Issues

Weak or dead batteries after long idle periods
Stale fuel causes clogged fuel lines and carburetors
Low or contaminated oil triggering automatic shutdown
Air filter blockages restricting engine airflow
Spark plug wear prevents ignition

Technicians note that these issues are among the most frequent causes of outage-day generator failure. Regular generator maintenance is essential to prevent these problems from developing over time.

According to Mike McNeil, owner of Long Island Power Systems, “The majority of generator failures we encounter during outages are completely preventable with proper maintenance, full system testing, and attention to the transfer switch before storm season arrives.”

Maintenance Gaps Observed Before Storm Season

Pre-season inspections are critical for ensuring generator readiness, yet property owners often miss several important steps.

Frequently Overlooked Maintenance Areas

Load bank testing under full electrical load conditions
Transfer switch inspection and operational testing
Coolant level checks in liquid-cooled systems
Fuel system contamination and sediment evaluation
Battery load testing instead of basic voltage checks

Professional Generac and Kohler generator maintenance programs are designed to address these gaps before storm season begins.

Importance of Transfer Switch Reliability

The transfer switch plays a central role in standby generator systems by signaling when to switch from utility power to backup power. If the transfer switch fails, the generator may start but not deliver power to the building.

According to research from the Pacific Northwest National Laboratory, preventive maintenance and operational testing of automatic transfer switches are essential for long-term reliability. The research further emphasizes that regular inspection helps identify wear, corrosion, and electrical faults before failure occurs.

Load Bank Testing Versus Routine Exercise Cycles

Routine exercise cycles are designed to keep generators lubricated and confirm basic startup function. However, they do not simulate real power demand.

Load bank testing applies a controlled electrical load to the generator, allowing technicians to evaluate performance under realistic operating conditions. This testing helps identify voltage drops, overheating risks, and reduced power output.

A qualified generator maintenance company typically performs load testing as part of a full system evaluation before storm season.

Preventive Generator Maintenance Before Storms

The updated guidance emphasizes preventive maintenance as the most effective way to reduce generator failure during severe weather. Regular inspections, fuel system care, battery testing, and transfer switch evaluation all contribute to improved system reliability.

By addressing these issues before storm season, property owners can reduce emergency service disruptions and improve long-term generator performance through consistent maintenance practices.
