Maybe the highly experienced HVAC professional didn't tell Cheri that
he'd
come out for free if the furnace failed again.

No, he didn't, but part of it is my fault for not checking myself to see
if they would.They did bill me, and not ask for money at the time of
service. I sent them a check, and decided that when it happened again, I
would use someone else since I didn't think they knew what they were
doing. The company I am using now does have a six months guarantee, but
I'm not sure they know either. I just know that I don't know, and am
assuming that the retrofit will take care of the problem for now. I
would sooner pay for that than have them keep coming back, waiting
around here for hours for them to actually get here, paying a service
charge, and then..."I can't find anything wrong with it." I hate having
to spend the money, but such is life. I'm old now, and hopefully the
retrofit lasts as long as I do. :-)
