Trusted Electricians in Henniker, NH, for Mini-Splits, Generators, and Electrical Upgrades

When your home needs backup power solutions or electrical upgrades, having a qualified electrician in Henniker ensures prompt service, especially during the harsh New Hampshire winters. O'Keefe & Flanagan Electric is a licensed and insured electrical contractor providing a wide range of residential electrical services throughout the Capital Region.

Mini-Split and Generator Work Built Around New Hampshire Homes

Two services that drive the most calls from Henniker homeowners are mini-split installations and generator hookups. We handle both as core work we perform weekly, with crews trained on the specific electrical requirements each system demands.

Mini-Split Installation in Henniker

Mini-splits provide flexible heating and cooling without ductwork, making them ideal for older Henniker homes that experience the changing seasons. As a Samsung Preferred Dealer, we install Samsung systems that can handle single-room or whole-house conditioning. These can be a good option for homes with additions or that need more focused heating and cooling.

Generator Installation and Electrical Hookups

Generator installation involves the electrical connections that allow a standby generator to power your home when the grid goes down. We consider local code requirements and your existing panels and wiring before installing Generac systems that automatically turn on when your home loses power. 

Full-Service Residential Electrical in Henniker

Beyond mini-splits and generators, your home needs reliable electrical work for everyday functionality. From updating aging panels to removing knob and tube wiring, we cover both specialized and standard electrical services in Henniker and the surrounding towns.

Electrical Panel Upgrades and Service Upgrades

Older panels run out of capacity as homeowners add new appliances, EV chargers, lighting, or circuits. We offer electrical panel upgrades for homes with aging equipment, tripped breakers, or systems that cannot support modern loads. Panel work requires careful planning and adherence to code, and we conduct safety and system checks after installation to ensure the work is completed correctly.

Knob and Tube Wiring Removal

Many older Henniker homes still have knob and tube wiring, which insurance companies and inspectors increasingly flag as a liability. We remove old wiring and bring circuits up to current standards by completely rewiring affected areas.

Kitchen and Bath Electrical Wiring

Kitchen and bathroom remodels require dedicated electrical work to safely install new appliances and lighting. We handle wiring upgrades, circuit installation, under-cabinet lighting, and outlet placement without taking on general contracting or finishes.

EV Charger Installation

We install residential EV chargers with dedicated circuits so you can charge your vehicle safely and conveniently at home. The chargers we install are compatible with many EV manufacturers, including Tesla and Ford.

Pool, Hot Tub, and Outdoor Electrical

Pool and spa work involves bonding, GFCI protection, and code compliance beyond standard circuits. We handle pool and spa electrical hookups and outdoor lighting to extend yard usability and security.
