"Roy and his team did a great job! They are professional, timely, thorough, and have an eye for detail. We bought a house that had a butchered, antiquated electrical system that was unsafe and chaotic. Roy and his team stepped in and not only sorted out the mess but put in its place a state-of-the-art electrical system that has been greatly simplified, and made safe and convenient (Roy spent time walking through the house with me talking through placement of switches and other features that ensured we had light in all the right places and flows perfectly with day-to-day use). Hire RGS, you'll be glad you did!"

Generator Install FAQs, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Many services include assembling the unit and securing it in the window. Confirm with your provider.
