"Very professional. Was completely honest about problem with the air conditioner. Besides the service call, I was only charged $5 to fix the actual problem with the a/c. It's nice to know they were so honest about the repair that was needed and didn't create something bigger that would cost hundereds. Would definitely use their services again."

"Since May 2011--when I purchased a home and a buyer's home warranty-- I have had three electric-related issues (ceiling fan replacements and electrical wiring issue) to which Dico Electric responded. The most recent was circa January 10, 2012. In each cases, I found Dico Electric representatives to be conscientious and helpful which was really exemplified during their last service call. Specifically, Dico Electric volunteered to come to my home in the early evening to examine an electrical wiring situation which was obviously of concern to me. The fact that they made a late service call saved me from coming home from work early the next day (that translates into dollars and cents!) As well, at the same time, I felt better that the electrical issue was reviewed and resolved very quickly by a professional. I noted that their mission/vision statement, which is stated in detail on their business card says, in part, "It is our goal to provide the best service and to exceed your expectations..."(mission statement) and 'it is our goal to be the only electrical contractor you will ever need (vision statement). Based on my experience, DICO went above and beyond in meeting my expectations and I will be using them again in the future."
