VETERAN OWNED I take great pride in my experience, expertise, quality, and customer service that I provide to meet the consumer’s needs. It is my mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, I take great care to work and communicate with every customer in a professional manner. My reputation is based on service, safety, and quality, regardless of how large or small the job.

"Firstly, WE never agreed on a price because it was handled through a 3rd party. Secondly, I received my invoice via email and that's how I paid it, by email using my card. By doing this, he made me feel horrible because it would take him 3 weeks to receive his money. By the way, he never said anything about meeting so that I could write him a check. Lastly, after paying the flat $700 invoice, I requested an itemized invoice for tax purposes. He responded by saying I was not going to get one because he wasn't going to measure each inch of wire. I explained that I didn't need that. All I wanted was the components used and labor. We ended by me not getting an invoice for taxes because he said I didn't need one for taxes (now he's account too) but my CPA requested one for a write off. I could see what kind of person he was so I just wrote back 2 words....forget it. There's something I do find curious. Who gets charged $700 exactly? I could have seen $625.19, you get what I mean. I'll never recommend his services to anyone I know for acting immature and whining about my necessary requests."

Generator Install questions, answered by experts

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.

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. 

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.
