"Excellent service all the time. I needed an dedicated outlet installed for a dryer and call Shey Weimann. They came out provided me a quote and did the work. That was about a year ago. Since then I had them replaced and relocated the 2 main electrical panels in my basement from one side to another as well as just the other day install another dedicated electrical over my stove for a microwave and replace 4 outlets in the kitchen and check and repair one of my outside outlets. Each time they pricing was far and their guys are very professional and clean up after they are done. Even if you say that is ok I will get it, you get no that is my job. When they replaced the panels I had an issues with the inspection that was not their fault (just a hard-nose inspector) but Shay and Linda made sure that it was addressed. This is one if not the best contractor I have ever dealt with. You receive Excellent service from the first call till the job is complete."

Generator Install questions, answered by experts

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

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. 

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.
