I received a phone call from someone claiming to be my heating company. A woman said I was due for maintenance on my heat system, and could she schedule it for Monday. Oh yes, and that they had changed their name from Sunset (my heating company) to Alpine (I suppose to match the name that was going to be on the truck that would appear on Monday. Cost would be $35. I said no one does a service call for $35 and that I would call my heating company and check. She hung up. My heating company had not called me.
