I called Bond Heating & Air after a bad experience with another company.  Chris showed up late but called so that was ok.  I was having an issue with the fan turning on and he said couldn't really diagnose what was going on but would charge $650. 00 to replace the fan.  WHAT!!!!! There are three screws and two wires... I said no thanks and replaced it myself for $120.00 (I also changed the thermostat for $40.00 and he wanted $180.00).   Also, he did not charge me for the service visit so that was good but I will not call him again for AC service.
