"Bill walked me through checking the outlet and circuits. We solved the problem with no service call needed. Harland has been my electrician since the early 2000's. They have completed many projects/repairs small and large (full panel replacement after water damage to installing a exterior spotlight). Staff answering calls is pleasant and professional, Bill gets back to customers usually the same day."

"I hired Mike to rewire and replace the outlets in my home as well as install brand new lighting, outlets and switches in the finished attic. His workmanship is nothing short of exceptional. It's plain to see that Mike is a professional who cares about his work, and more importantly his clients. His pricing is also very competitive. No need to worry about mile-long contracts and being charged hourly on top of exorbitant fees etc. If you are looking for any kind of electrical work to be done in your home, I highly recommend you give Mike a call or text. I guarantee your experience will be as good as mine was!"

"Michael came to my house and upgraded my 100 amp panel to a 200 amp panel for my solar installation project I had coming up. He was very thorough in explaining all the work that needed to be done, how long I would be without power, and was very knowledgeable in all of the questions I had. After removing my service and replacing it with the new 200 amp, he went through the entire house and checked what each breaker was wired to and marked it inside my panel very neat and organized. Couldn’t be happier with the experience from start to finish. If you need any work done to your home I highly recommend Mike and I will definitely be contacting him in the future if I ever need any other work done. Thanks Mike!!!"

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.
