"FM Generator installed the whole house unit for much less than I thought it would be. They have been servicing it ever since. I am very pleased with the responsiveness of FM Genderator and the quality of their service. I live right on the ocean and the original generator died just before the warranty period. This is primarily due to the corrosive nature of the salt air. They reinstalled a new one quickly. I am very happy with their services, and have recommended them to others in my neighborhood."

"From the office folks to the electrician who did the work -- friendly and professional. They quoted the lowest price of three estimates and did the work within a couple of weeks. I purchased my generator elsewhere online... and VMA walked me thru the process of hooking it up, running it, and shutting it down. Very helpful."

"I recently leased a Hyundai Ioniq 5, my first EV, and Joe installed a level 2 charger for us. He really knew his stuff regarding chargers and how to install them. He also upgraded our panel to provide a generator plug which I can use with the V2L feature of the car OR with a propane fueled generator. It was great working with Joe."

"We've used Wired Electrical a few times now and most recently, to install a motion activated floodlight to light up the driveway and walkway. As always, our appointment was arranged courteously and easily, and Phil was as professional as they come - he got the light installed pretty quickly, and it works wonderfully! No more dark driveway! I highly recommend Wired Electrical - no fuss, fantastic results."

"Very responsive, came out for a quote in a timely manner which I can't say many others did. Has responded quickly to my emails to answer any question I have posed. The crew came on time to position the generator and had it in place as described. As soon as Tim and Robert were notified of gas connection they scheduled final install, showed up exactly on time and completed work in a very professional manner. Very happy with the entire process."

"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

Generator Install questions, answered by experts

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

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. 

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
