We chose Chicago Electrical to replace a 400 amp line into the house, a 100 amp service for our hot tub and landscaping water feature, and to hook up our generator for power outages. We couldn't have asked for better service or workmanship. The electricians took their time to explain what they were doing and used high-quality supplies. The technician, Leah, was very professional and knowledgeable. It was a pleasure to have them in our home. Their work was praised by the electrical inspector.
