What Clients Say
Only company in town that responded in a timely manner when I called for an estimate. While others took 3-4 days, I was contacted within a day after sending an online inquiry to McCardel. I didn't even bother getting other quotes elsewhere being that I was concerned I wouldn't get prompt service if an issue occurred. Salesman was great, sold what I needed and nothing more. Unit installed shortly after and solved all my water issues. Only thing I wasn't completely satisficed with was the mess that was left after the install. Still gave 5 stars because the pros outweighed the cons. Would recommend them to anyone.
