"Drew and the entire crew made this experience seamless. The installers were polite, friendly, competent and and tidy. The pre and post support was fantastic, the expectations around logistics, installation timing and ongoing service support was spot on. These guys are pros and the solution cost was clearly the best in my search for authorized service providers of Generac generators. Hire them you won't go wrong. Vin M Dover NH"

"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 questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.
