"I have a very good impression of Mr. Morton and appreciate his efficiency and speed in getting my generator back in service. I have asked him to put me on his list for a yearly evaluation. I am trusting that the next time there is a power failure my generator will be back in operation."

"I had American Electric complete the wiring for my 24x40 garage along with a 200-amp panel upgrade to my house, and I couldn’t be happier with the results. From start to finish, the communication was excellent, they were punctual, reliable, and the quality of work was outstanding. Everything was done professionally and exactly as discussed. I would absolutely refer them again and highly recommend them to anyone needing electrical work done."

"Electrical & Security Solutions are the best! I have needed their services more than once to replace lights, a ceiling fan and also to install a new electrical box and breaker for our garbage disposal. Tyler promptly responded every time I called and he and Casey are both friendly, efficient and skillful. Aside from the excellent service, the qualities I appreciate the most is honesty for what work needs to be done and how Tyler is also very budget consciousness."
