Your Local Electrician for Londonderry, NH, Homes

When you need electrical work, you want a licensed electrician who answers your questions and follows through. O'Keefe & Flanagan Electric is locally owned and based in Concord, serving Londonderry homeowners with residential electrical services. If you're looking for a reliable electrician in Londonderry, New Hampshire, we provide residential electrical services ranging from mini-split installation and generator setup to EV charger installation and outdoor electrical work.

Mini-Split and Generator Installation in Londonderry

Southern New Hampshire's seasons require reliable heating and cooling, and mini-splits can handle both demands efficiently. Mini-split installation provides zoned temperature control without major construction, and we'll discuss the right setup for your home's layout before scheduling. We install Samsung systems as a preferred dealer.

Generators provide crucial backup when storms knock out power, and a whole-home generator can keep your house running when the neighborhood goes dark. We install Generac generators and assess your electrical load to recommend the right unit for your home. 

Electrical Services Available to Londonderry Homeowners

We offer the full range of residential electrical work for homeowners across Londonderry, from updating old panels and wiring to supporting new projects that require electrical work.

Panel Upgrades and Service Upgrades

Tripping breakers, limited capacity for new appliances, and remodels demanding more power are common reasons homeowners need a panel upgrade. An outdated panel limits your home's electrical potential and poses safety concerns. We assess what you have and recommend the service upgrade that fits your current and future needs. Once the upgrade is complete, we’ll also perform safety checks on the system.

Knob and Tube Wiring Removal

Older Londonderry homes still carry knob and tube wiring, which wasn't built for modern electrical demand. Many insurers even flag it as a liability. We remove knob and tube wiring and replace it with code-compliant wiring that supports how you use your home today.

EV Charger Installation

Home EV charging has become practical for many households in Londonderry. We’ll install a Level 2 EV charger that’s compatible with your vehicle and designed for convenient home charging.

Kitchen, Bath, Pool, and Outdoor Electrical

We provide electrical work for kitchen and bathroom remodels, including outlets, circuits, ventilation fans, and code compliance, and we’ll work alongside your contractor to keep the electrical portion of the remodel on schedule. We also cover pool and spa electrical systems and outdoor lighting to ensure safe, properly wired exterior spaces.
