I have used McCormick Electrical Services in the past for various things needing attention. Most recently, they installed a whole house generator for me and signed me up for their warranty and maintenance program. It is rare that I am able to do business with an outfit that actually delivers on what they say. McCormick Electrical Services delivers exactly what they say. Not only do they deliver, but they make it maintenance free for me. I don't have to do anything for maintenance. They give me a call or text and send me the name and a "picture" of the technician that will be arriving to perform the maintenance. I like that they are thinking about security and that they are transparent in providing that level of comfort for their customer. This company has provided a professional experience every time, and I consider them providing the best customer service that I have ever had from any business.
