Northeast Iowa Mechanical I use all of the time. I always buy parts from them. I have not personally used their service other than to buy parts, but I hear they are fantastic through my friend who uses them. Recently, I purchased furnace parts through them. The quality of their products is really good! Excellent quality. The sales staff always treats me really good and they do not even know me personally. I figure if they treat me really good and have not met me in person yet, they must be a really good company with good customer service. Northeast Iowa Mechanical has been so easy to work with. I just call up and tell them what I need and they send the parts right out to me. Because I am always working, they sometimes have left the parts for me to pick up on Saturday, which is such a convenience for me. I have just left them a check on the door and get my part. How nice is that! They seem to always be well stocked and never once did I run into a part not being available. They can order things but never have had to yet. I highly recommend them.
