Generator Types and Brands We Install

O’Keefe and Flanagan Electric focuses on standby generator installation, permanent systems that automatically turn on when power goes out and keep your home or business running.

We install trusted standby generators from:

Generac: A popular choice across New Hampshire for dependable performance and strong long-term support.
Kohler: Built for durability, with proven engineering and solid warranty coverage.

Maintenance Plans: Keep Your Generator Ready for Any Outage

Power outages do not schedule themselves, and your generator should not be a “hope it starts” plan. Annual generator maintenance is one of the simplest ways to keep your system dependable when the lights go out.

With routine inspections and testing, you can catch small issues before they become expensive repairs, improve overall performance and fuel efficiency, and extend the life of your standby generator. For homeowners, that means staying comfortable and avoiding preventable surprises during storms. For businesses, it means less downtime, fewer interruptions, and more confidence that operations can continue.

Our generator maintenance plans typically include:

System inspection and diagnostics
Fuel and fluid level checks
Test runs under load
Replacement of minor parts and routine adjustments

Regular service reduces the risk of unexpected breakdowns and helps keep your generator ready year-round across Concord and Central New Hampshire.
