"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"When warning lights appeared on our General generator we called the man who installed - he never returned the call. We called Michael and Son, paid for the generator maintenance plan, and while someone came to look at the unit, no one ever got back to us about what needed to be done to get the generator working again. We called the generator division and the main offices of Michael and Son and still never received a call, let alone a solution to the problem. In desperation, I searched the web for someone with experience in Generac generators and found Rollins Repair. Within an hour, Mr. Rollins returned my call and came to the house that evening, even though it was quite a long trip for him. Mr. Rollins made a couple of trips back over the next few days, trying to diagnose the problem. Finally he took the unit with him, and after trying to repair it, he dealt with Generac and the warranty and got us a new unit for less than I expected a repair to cost. Mr. Rollins could not have been more professional and persistent. He kept us informed every step of the way. He spent hours in work and travel time, and we are thrilled with the new unit which works beautifully. My husband and I give him the highest possible rating, and look forward to working with him for a long time to come."

"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."

"Larry and his crew upgraded our under cabinet lighting with new LED lighting, and specialized outlet. Not only was our home and its contents treated as if they lived here, the job was done professionally. So much so, that the only issue we had was when the switch/outlet face plate screws came loose. I didn’t even bother calling Larry, I tightened them myself. The lighting is on, literally 24 hours per day since the install, with zero issues. Love these guys."
