Hello, virtually no electricians have the air conditioning *controls experience to wire AC thermostats... air heat man could easily be correct and that a fuse deep inside one of the furnace's or air handlers has been blown.
If you can tell me which direction you are from the center of the nearest city I can most likely locate a well rated AC controls technician in your area with good ratings, we can go from there.
