"From the office folks to the electrician who did the work -- friendly and professional. They quoted the lowest price of three estimates and did the work within a couple of weeks. I purchased my generator elsewhere online... and VMA walked me thru the process of hooking it up, running it, and shutting it down. Very helpful."

"The furnaces were replaced in two different houses without any problems. The generator was placed in one of the houses with many delays. Waiting for parts we were told. When it was finally assembled it worked but daily test runs were happening. When we called to have our yearly check we were told it should only run once a week. A part needed to be replaced. Wilson Bros. shared that expense. It ran for about the next 5 years with constant maintenance but this year the mother board is gone. Wilson Bros have been wonderful but I question the quality of their equipment. One of the gas furnaces also requires costly maintenance. We never had this with our other gas furnaces. Love Wilson Bros. Don't like their replacement equipment. I just thought new things should last a little."

"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!!!"

"From the initial contact via Angi to the finished installation, this was a very pleasant experience. Ray came by on the same day to check out the specific location and circumstances, and sent the very reasonable estimate the next day. We arranged for installation the following week, and the members of his team did an excellent job. We now have an EV charger that works very well. Highly recommended!"
