I have a Carrier furnace model 58CVA which has been used for 3 mild winters. When I tried to start it last week, the blower didn't come on. The service man says it needs a new motor (variable speed) which will cost about $960 plus labor. I called Carrier about the warranty which was advertised as having a "five year limited warranty on the entire unit" to find out just what this consisted of. The rep told me there was no 5-year warranty. Furthermore she refused to tell me what the 5-year warranty, still being adverized, consisted of. Moral of the story: Don't believe the advertized warranty...get it all in writing.
