"Bill H from Gambino Electric showed up promptly on time for the job. There were some edge ceiling tiles that needed to be removed to reach the power line and Bill did very clean work with the removal and disposal. Bill showed cross sections of the older range power line and the new line installed, describing the differences in insulation and safety features of the newer line. Bill went above and beyond by detecting the wrong cord on the new range, and replaced this with the proper range gauge power cord. Bill also helped us to correctly position and level the new range appliance. I would recommend Bill and Gambino Electric for any similar household wiring job where safety and quality of work are a priority."

"From scheduling through installation had an excellent experience. This was a surprisingly pleasant morning with not only highly-competent and professional electrical services rendered, but done so by two gentlemen operating swiftly and politely with integrity. I would use them again in a heartbeat and absolutely recommend their services."

"We hired Young's Electrical Service after receiving quotes from several other companies and having them not show up. Young's arrived when promised, meticulously completed the install and cleaned up after the project. We plan to hire them for additional work in the future."

"I had two bedrooms in my house with no overhead lights installed. This was not an easy fix for me and a complicated install. I'm so glad I called Pro Electrician. A new line had to be run up in the attic and over and into the center of the bedroom. They did a fantastic job. This is a finished house and The technician was extremely neat and efficient and explained everything to me. And i'm glad that I didn't try this on my own. Now I finally have lights controlled by the wall switch and also had ceiling fans installed. 100 % satisfied and definitely would recommend them."

Generator Install FAQs, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
