Comments: Istalled light switch; 2 electrical outlets and troubleshoot and fix bad existing outlet and lights. Quality work performed to my satisfaction. They diplayed a high level of knowledge and experience for the work in which they performed. They showed up on time, explained what was needed and cleaned up after themselves. And the cost is very reasonable.

Comments: Chester provided excellent customer service and a good job installing our over-the-range, black stainless steel microwave. However there is a noticeable small dent in front of microwave. Didn't see it until the next day after service was completed. Yes, I would recommend his services. And I would also do before & after pics (which we did not do). Overall, good job.

He also answered all of questions and addressed other concerns unrelated to what I hired him for. He even charged me less than was quoted over the phone, but I was so pleased with his service than I gave him the original price.

Comments: Mr. Chester was on-time, very professional, but also incredibly nice and friendly (even to my dogs!) He didn't rush the job and even took care of a few other things I needed done around the house, and gave advice and estimates for future jobs. The pricing was very fair, and Integrated Systems will be our go-to for any future electrical work.

Review Date: 08/20/2016 | Author: Louisia W.

Comments: Since the switch was an older model, thought he would have to come back the following week when he found the part, so we scheduled an appointment for the following week. He left and came back about 30 minutes with the part and did the install!. He also replaced some neon lights in a fixture in my basement, which he did not have to do. I will definitely call him back as I have a number of other minor job that require work. Very nice and personable.

Comments: Chester was very creative in coming up with a solution to an ongoing problem. His varied abilities (problem-solving, engineering, home-repair) combined to make this a win-win situation for us. Unfortunately, the job took much longer to complete than he thought it would, so he spent a day here instead of a few hours. Great work ethic.
