Not only do some thermostats make nothing happen, some are programmed to display a desired temperature regardless of what the temperature really is.

I had a guy from Empire Plumbing come to fix my furnace. He said the control box needed to be replaced. He clearly told me the box alone cost $587.00 and asked me if I wanted to proceed. I figured that I may as well let him continue since I would still have to pay that much or more for the box if I bought it myself. He also cleaned the filter. When he was done, I noticed that he didn't charge me for labor. But after calling some suppliers I found out that the box could be purchased for $134.00. My furnace is easily accessible at floor level. So, he was here for about an hour and charged me $453.00 just for labor!
