"We really like the professional job done by Paul, James III and Nate, they answered all our questions and explained everything to our understanding. They are no doubt well-trained in their field and dedicated to the reputation of the company. Kudos to our saleperson Tom, who also happens to be the president. We had on-location visits from 3 companies to have a whole-house generator installed and no doubt picked the best company."

"They were fantastic! They were polite, fast, organized, good clean up, and explained everything. The quality of the generator looks durable, and could last longer. They are the only company who told me that the generator needed to be serviced for every 2 years instead of every year. They also installed it on a stoned pad instead of a concrete which saved me a lot of money. The piping inside of the house was a flexible steel coil. They also do service calls."

"Immediate response to our inquiry. Reasonably priced and extremely willing to accommodate our needs -willing to make two trips to the residence as we wanted the old water heater pulled one day so that we could access and paint the small utility room prior to installing the new water heater the next morning"

"Michael, the owner of MNW Construction, was awesome to work with. This bathroom remodel had special circumstances around it for a disabled family member and Mike took all factors into consideration. He listened to our needs, envisioned a functional design, picked out all materials, fixtures, colors, while working well within our set budget. Mike is extremely talented, educated and passionate about his trade and is a hard working business owner. He and his crew are great to work with and take pride in their work. Highly recommend!"

Generator Install FAQs, answered by experts

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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. 

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

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.
