"Our existing generator died. James diagnosed the problem and gave us a few options to repair or replace it. We chose to replace it. James handled everything, from getting and installing the new generator to electrical and fuel (propane) connections. We have asked him to schedule us for the annual maintenance on the machine. We are pleased, though we haven't lost power since it was installed, LOL."

"Simply amazing from start to finish! I can't say enough nice things about this company or the people that I dealt with. They were all professional, friendly and they did great work. They called me just minutes after I clicked their name on Angi's List and had someone out to give me an estimate and had my appointment date set in record time from most companies that I have dealt with for home improvement. I hate having people in my house working but I felt totally comfortable with them. The work they did was exceptional. We got a new power box (breaker box - whatever it's call) and a new meter and a couple of new outlets put in. We also got new smoke detectors throughout the house. They had to work around some issues and relocate a bit of pipe from out water filter system that was in their way. And they just took care of it without any complaints. I didn't have to do anything. They took care of it all and had the inspector come out and get it approved. I feel safe in my home now. I highly recommend this company and I will be calling them for any future electrical work that I need done."

"Anthony and his team do expert electrical work of all kinds. We are a 145 year old non-profit organization with buildings and grounds, and have contracted with Technician Engineers Group (TEG) on two large projects (and several small ones) over the last 15 years. One project rewired a large 125 year old building listed on the National Register of Historic Places, and one installed an extensive outdoor lighting system. In these two unusual situations TEG worked closely with us to find innovative solutions to our unique needs. We are very pleased with the results, enjoyed their can-do approach, and highly recommend this company for any electrical challenge. We found TEG reliable, honest, on time, and all the work was completed ahead of schedule."
