I am a first time customer of Northeast Iowa Mechanical. Mostly, I have just bought various products from them. They seem to be very knowledgeable, and very professional individuals, and I will probably have them come out and do some service work for me in the future. I know that they know their business well, and the product they recommended to me really worked. It did an excellent job. So, I am happy with my purchase, and very satisfied with Northeast Iowa Mechanical!
