"Excellent service from the technician. The light fixture was from from Turkey, and was very tricky with installing (including not having exactly the right base to hang). He figured out how to make it look perfect and gave us lots of tips for our upcoming house with no pressure. Courteous, professional, and prompt service! We will hire them again!"

"They are incredible!! They are by far the nicest, most conscientious electricians I've ever worked with. They're honest and get the job done. We had a major panel upgrade and they handled the whole thing from planning to permits. They were at our house for the inspection and handled the whole process. Not only that, they were friendly and got back to me right away when I had a question. They then followed up with me when the project was done to make sure all went well and if I needed anything else. These folks are THE BEST!!"

"Rich contacted me after searching for an IT technician to set up Wi Fi and security cameras. He is highly knowledgeable about various tech and electrical aspects. The installation took a couple of hours, as we had to run new internet cables in our home. The Wi Fi signal significantly improved with wireless coverage throughout the house. Once the installation was complete, Rich programmed the camera notifications and alert zones as per our request. He also gave us a quick tutorial on adjusting settings for both the new cameras and Wi Fi system."

Generator Install FAQs, answered by experts

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. 

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.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
