[RFI] Getting a Gas Furnace, and Electric AC unit...

 Don't know whether to top post or bottom post - but I don't care for
 being described as "part of the problem". You do not know the
 situation or the background and that comment is unfair and disturbing
. People have priorities driven by personal situations - that system
 was installed 3 days after I left hospital - 30 days later I was back
 in thru the ER and was on edge buying the farm for another week - and
 am now faced with possibly facing same situation again .  Some spurs
 every 18 khz are sure as hell not my biggest concern at this point 
 have they been for past year.

 I was just answering the question of specific manufacturer model
 numbers that have exhibited an issue.
