Certified Generac Dealer in Durham
Penfold Electric Ltd is a family-owned electrical contractor and certified Generac dealer based in the Durham Region. Our licensed electricians install automatic standby generators, portable generator hookups and transfer switches for homes, businesses and industrial facilities across Durham, the GTA and Northumberland County. When an ice storm or summer outage knocks the grid down, a standby generator starts on its own within seconds. Your heat stays on, your sump pump keeps running and your basement stays dry, whether you’re home or not.
We size every system to what you actually need, from essential circuits to whole-home coverage, handle the electrical work and ESA paperwork, and back the installation with our 1 year labour warranty on top of Generac’s manufacturer warranty. We service and maintain generators too, so yours starts every single time. With more than 40 years of experience at honest prices, Penfold Electric keeps the power on when it matters most.

Frequently Asked Questions
What size generator do I need for my home?
It depends on what you want to keep running. Essential circuits like heat, the sump pump, the fridge and a few lights need a smaller unit than whole-home coverage with air conditioning. We run a load calculation as part of your free quote and recommend the right Generac size for your home and budget, no guesswork.
What's the difference between a standby generator and a portable generator?
A standby generator is permanently installed outside, runs on natural gas or propane and turns on automatically within seconds of an outage, even when nobody is home. A portable generator costs less up front but has to be rolled out, fuelled and connected by hand. We install both, including the transfer switch that lets a portable generator safely power your panel.
How much does a generator installation cost?
Every installation is quoted individually because generator size, panel location and the circuits you want covered all change the price. The quote is free and there’s no obligation. If a standby system isn’t in the budget right now, a portable hookup with a transfer switch is an affordable way to get protected.
Why does a generator need to be installed by a licensed electrician?
Connecting a generator to your panel requires a transfer switch that prevents power from backfeeding into the grid, which is dangerous for your family and for hydro crews working on the lines. In Ontario, this work must be done by a Licensed Electrical Contractor with ESA notification. Our electricians install it safely, to code, with the paperwork handled.
Do you service and repair generators?
Yes. We maintain and repair generators so they start when you actually need them, and regular maintenance keeps your Generac warranty in good standing. Ask about maintenance when you book your installation, or give us a call if your existing generator isn’t running right.
Do you install backup power for businesses?
Yes. We install commercial and industrial standby systems, automatic transfer switches and the panel work to back up critical circuits, from refrigeration and POS systems to three-phase equipment. A few hours of downtime can cost more than the generator itself. We’ll size a system that keeps your operation running.
