Louis came out the first time and replaced two switches in our panel. The problem was that one switch kept tripping and the other was the wrong manufacturer, which he brought to our attention. This recommendation on his part, saved us from a potential panel fire. We paid full price for this first visit. When it turned out two days later, that this didn't fix the tripping problem, he came back out and trouble shot the problem, until it was fixed at no additional charge. I was pleasantly surprised, as it took him some significant time. Honest and dependable. Follows through with what they promise. Highly recommend! Will definitely use again.
