I had installed a remote control fan and got the light to work, but not the fan. The problem was my wiring the wall switch. D&D came and fixed that very quickly. I also had them work on a switch in my garage, but the problem was just new bulbs and not the wiring, Duh! Youd think at age 65 Id know better. Anyway, they also worked on my waterfall switch and then they had to fix the wiring in my basement which I had initially done myself (first mistake). All in all they were very fast and pricing was very reasonable. I would highly recommend them and will hire them again if I needed to fix wiring that I screwed up. :-)
