"Adam called me immediately and met me that same day. I hired the company and they cut my grass that same day. They used a ride on mower and my land is uneven so some areas were shorter than others. Two days later they spread 10 yards of hemlock mulch and recut some areas of my grass with push mower. They will use a push mower in the future. My yard now looks beautifully landscaped. Communication is definately key with this company. They aim to please!!"

"An outlet wasn't working.  Called and he said he'd be there that day or the next.  Arrived as promised the following day.  Pleasant, efficient and got the outlet working.  Would definitely use him again."

"It was a pleasure working with Justin and Dave. They were kind, reliable, and a pleasure to have in our home. High-level integrity and tenacity. They found several clusters of live knob and tube lighting, despite a previous electrician signing off that all knob and tube was removed. I would hire them again without question."

Generator Install questions, answered by experts

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
