"Wow, they just left and I am so beyond impressed with everything, from start to finish. Adam helped with our estimate and was a pleasure to work with. He came next day for our estimate and from there, went above and beyond to answer every single question and concern of mine, he was fair in his pricing, very timely in his responses and even remembered the layout of our home when I called a month later. They were even able to schedule the job next day due to the inclement weather. Jim and Matt arrived early and were so courteous and pleasant to work with (they were even extremely considerate of my infant's nap schedule). We had them install two new outlets for ac's and electronics and they had to snake the wires in impossible places. Jim listened to every single one of my concerns and came up with excellent solutions and they left everything in better condition than they found it. When I asked if there was another way to get the job done, he listened and offered to change his plan. It was so nice having a contractor actually listen to you and work with you. I will definitely be hiring them again - I am so glad I finally found an electrician that is respectful of an older home. Thank you Adam, Jim & Matt! You guys rock!"

"John is a very professional electrician and is very knowledgeable about what he does. Him and his crew have many years of experience doing this kind of work and it really shows. I just had them install a new car charger for me and I couldn’t be any happier with the results!"

"Fast and super helpful. Gave me a proposal right away. Started work same week. If deviations were needed, was specific on what and why. Reasonable and fair pricing, and honest about their capabilities and areas of expertise. Professional team and went out the way to provide additional references for other concerns. I also appreciated the video Fabio took to show me the before and after, especially in areas I was unable to see."

Generator Install questions, 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.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
