"A wonderful experience for a complicated project! I would use Green Sun Energy again for any service they provide. They made the generator install as easy and painless as possible. The crew was kind and efficient. Lots to do for an install such as this but they did it quickly, efficiently and were extremely organized. Just how I like it! Thank you so much!! We feel protected for whatever comes our way."

"Roy is really a prof. He installed two overhead fans and a hanging lamp. The fans had a complicated control system but he was able to get them to work flawlessly. Bonus: he is really a nice person and he cleaned up too! I would recommend his work to anyone."

"I have used Pipe Works on numerous occasions as of this date and find them to provide excellent service at competitive prices. Their associates are great to work with and their prices are competitive. The work is always completed on time, as promised and the work area is left clean. I appreciate that they point out things that need repair in the not so distant future. It was great to wake up the other day with power coming from my new Kohler Generator"

"I needed a Transfer Switch for a portable generator installed, and Mike responded immediately! As a first time homeowner, finding an honest expert you can trust is difficult, but Mike has the proven experience and excellent communication skills to make any customer feel at ease. He kept to his word and did the job cleanly within the same day. For me, his price was absolutely fair. Mike will be my go-to for any electrical needs going forward. Thanks, Mike! -Eddie"

Generator Install FAQs, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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. 

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.
