"They did an excellent job of installing the new panel at a reasonable price. Also they had financing options that were same as cash. I was provided some options of circuit breakers and the price with the options. The differences in breaker were explained and the code requirements for my area was also explained and compared to other local code standards. I was able to customize the options a little bit based on my needs and I have more space in the panel if I have additional requirements. Going from a box from the 1960’s to a modern solution mad a lot of sense. The installation was smooth with only a short time without power. Throughout the process, I was well informed of the progress. My family was able to work remotely from home during most of the install without too much disruption. (Used cell phone for internet and laptops while power was off.) They even installed a monitoring system for me to track the electrical use of the house. Overall they did a great job and I am very satisfied."
