Called them on Friday, early afternoon. They said they couldn't get to me until Monday afternoon. $60 diagnostic charge to come out. I had no heat in my gas furnace. Over the weekend, I found a red light blinking 6 times. Chart on furnace said it meant that the "electrical polarization was reversed". Monday afternoon repair man shows up. I tell him what I found about the 6 blinks of the red light. He looks everything over and says I need a new thermostat. I asked if there was a way for him to confirm that? He looks around some more and says "these wires here were reversed, it should work fine". It was fixed. He goes out to his truck and comes back and says "that will be $134!" I said "WHAT?" It had been 30 minutes since he arrived and he misdiagnosed it at first - after I had correctly diagnosed it, then tells me it was $60 to diagnose and $75 to "FIX"! The diagnosis WAS the fix. I wasn't given an option to spend $75 more to fix it.
