Benefits of Preventative Maintenance

As a generator owner, it’s crucial to maximize the lifespan and efficiency of your unit. To achieve this, it is highly recommended that all generator owners subscribe to a generator maintenance service plan. This will ensure that your generator operates efficiently when you need it most and help identify any potential issues before they become serious problems.

Keep Your Generator Running

Like any critical piece of equipment, a generator performs best when it receives regular care and attention. Preventative maintenance helps extend the lifespan of both residential and commercial generators while reducing the risk of unexpected breakdowns. Routine inspections and servicing ensure reliable operation, improved efficiency, and dependable backup power when you need it most.

Catch Problems Quickly

A generator maintenance plan includes routine inspections by trained technicians who evaluate system performance and identify potential concerns. Addressing wear, damage, or minor malfunctions early helps prevent unexpected failures during power outages. Regular service improves reliability, reduces repair costs, and ensures your residential or commercial generator remains prepared to provide dependable backup power when needed.

Improve Efficiency

The better you care for your generator, the better it will care for you. Sticking to a maintenance schedule is key! Weisman Electric Co. offers a variety of generator service maintenance plans to make sure you never miss a routine service or wait too long to have your generator mechanic assess your unit.

What Does Generator Maintenance Include?

A professional generator maintenance service goes beyond simply changing the oil. Depending on the generator and service plan, our technicians inspect the engine, electrical connections, battery, transfer switch, fuel system, fluids, belts, hoses, exhaust system, controls, and other critical components. Testing helps identify developing problems that may affect the generator’s ability to start, transfer power, or operate under load.

Regular servicing also gives homeowners and businesses an opportunity to address minor issues before they develop into more expensive generator repairs or leave the backup power system unavailable during an outage.

Why Seek Repair?

If your generator is broken or malfunctioning, it’s important not to delay getting it fixed. As soon as you notice any issues with your unit, contact your generator contractor repair shop without hesitation. If you wait too long, you might forget about the problem and end up facing a power outage with a generator that doesn’t work.

Reach out to Weisman Electric Co. as soon as you suspect anything is wrong so we can help you get your unit repaired!

Generator Needs Service or Repair

Signs Your Generator Needs Service or Repair

A standby generator may need professional attention if you notice difficulty starting, unusual noises or vibrations, warning lights, fuel or oil leaks, reduced performance, battery problems, or failure to transfer power correctly during a test or outage. Even if the generator continues to operate, these signs should not be ignored.

Prompt generator repair can help prevent a relatively minor issue from becoming a more serious mechanical or electrical failure. If your generator has stopped working or is not performing as expected, Weisman Electric can inspect the system and determine the appropriate repair.

Residential and Commercial Generator Maintenance Plans

Weisman Electric provides generator maintenance services for both residential and commercial backup power systems. Our preventive maintenance agreements can be customized around the generator type, operating conditions, manufacturer recommendations, and the needs of the property.

For residential customers, scheduled maintenance helps keep standby generators prepared to protect essential home systems during an outage. For commercial properties, regular service helps reduce the risk of unexpected downtime and supports continuity when reliable backup power is critical to business operations.

How Often Should a Generator Be Serviced?

Generator service frequency depends on factors such as the generator’s make and model, operating hours, fuel type, environmental conditions, and manufacturer recommendations. Many standby systems benefit from scheduled preventive maintenance at least twice a year, while generators that operate frequently or under demanding conditions may require more frequent attention.

Weisman Electric offers semi-annual preventive maintenance contracts that include spring and fall inspections. Scheduling service before periods when severe weather or outages are more likely can help identify maintenance needs before you depend on the generator for backup power.
