How GEM Keeps Your Generator Ready for Outages

Generator maintenance helps ensure your system is ready to perform safely and reliably.

GEM’s electricians provide thorough, proactive service designed to keep your generator prepared when it matters most.

We inspect your generator and surrounding components for signs of wear, damage, or leaks. This helps identify potential issues before they impact performance.

Proper fluid levels are essential for reliable operation. During service, we check engine oil, inspect the oil filter, and verify your coolant and other key fluids so your generator is ready to run when needed.

A weak or failing battery is one of the most common causes of generator failure, which is why we test your battery and inspect connections to help ensure dependable starts.

We review electrical connections and inspect the transfer switch for proper operation, ensuring power transitions safely and smoothly during an outage.

We run your generator to confirm it starts correctly and operates as designed. This performance test helps verify readiness under real-world conditions.

After service, we explain our findings in plain language and provide honest recommendations. You’ll know exactly how your generator is performing and what steps can help keep it reliable.

Patricia Quigley
New resident needing plumber to improve drainage of bathroom sinks and stop leaky faucets. As first plumber I called did not call me back, I called Gem for help. William and Mark were sent to provide service within 2 hours. Problems corrected after thorough discussion of options and pricing for each. Selected the replacement option for leaking faucets, which resulted in spending more money than anticipated, but they selected good looking faucets from supplier and returned to install them. I elected to enter into a one year contract to secure HVAC service for the year, eliminating the dispatch fee. I am pleased with the new well functioning faucets. Good communication with technicians and office representative, Melissa.

Frequently Asked Questions About Generator Maintenance

What happens during a generator maintenance visit?

An electrician checks the generator, looks over the fluids and battery, tests how it runs, and reviews the electrical connections. Maintenance may also include inspecting components such as spark plugs and filters to ensure reliable operation. After the visit, you’ll receive clear feedback along with any recommendations for keeping your generator ready for the next outage.

How often should my generator be professionally maintained?

Most residential generators should be professionally maintained once a year. Annual service allows electricians to inspect components, test operation, and address wear before problems develop. Regular maintenance helps support reliable and safe performance during outages.

Why is generator maintenance important if my generator hasn’t been used?

Generators can develop problems even when they are not running. Batteries can weaken, fluids can degrade, and electrical components can deteriorate over time. Maintenance ensures your generator is prepared to start and operate properly during a power outage.

Can generator maintenance help prevent startup failures?

Routine maintenance helps reduce common causes of startup failure. GEM electricians check batteries, inspect connections, and evaluate components that affect starting performance. This improves reliability when the generator is needed during an outage.

Does GEM service all types of residential generators?

GEM services most residential generator systems, including permanently installed units and some portable generators. Our electricians evaluate the generator and electrical connections during maintenance visits. Service is then tailored to the specific equipment installed at your home.
