Testimonials

"Professional company. My house was built in 1964 and needed a lot of electrical upgrades to be up to code. We started with replacing my very old panel and moved on to updating light fixtures and adding lights wherever I requested, some for efficiency and other lighting for aesthetics. The qualify of work was A+. Anyone who owns a older home knows how scary replacing anything is, however everything went seamless. The modern lights, new panel and outlets added so much value to my home. With most lights and technology now being energy efficient I'm already noticing a difference on my electric bill. Great pricing as well! Highly recommend Diagnostic Guys!"

"I was having Electrical issues When trying to run power equipment at my commercial Shop space. I looked around to find a business to diagnose and address the lack of Power at my shop. I found diagnostic guys online and was able to contact them and get an appointment in a timely manner. Tim stopped by and checked out all of our outlets, he addressed our power shortage and also gave us a variety of different options. Tim was able to diagnose for our lack of power, he helped us fix electrical wiring and install outlet. Overall my experience with this company was great I am pleased with the work they did and the professionalism they demonstrated in doing so. I refer them to all Associates and friends that I have and will use them again in the future."

"Isaiah put a light above our shower for us. He was very professional and explained why a regular light would not work, but it needed to be sealed from moisture for corrosion protection and damage. We were very grateful. Excellent service, and really cared about doing the job right. I would absolutely recommend them."

"We had DG over to install some can lights in our kitchen. My wife and I first thought about getting them when we were both stuck home during a blizzard. DG sent someone out that day (in the storm!) to give us an estimate. Tim came in to look at the space and spent time just listening to what we wanted. He told us what methods they usually use and what products the recommend, but said they would work with us on what we wanted and wasn't pushing pricey stuff on us. He gave us a great plan and a clear price. They showed up a few days later and installed the lights in three hours. There was no mess, and everything looks and works great. If you're picking any two of quality, speedy, cheap service, DG delivers on quality and speed. The price was still right in the ballpark of other quotes, and they even offered us a discount when they heard that my wife is an educator, saying they want to help out the community when they can. I can't recommend them highly enough. They're the best."
