I have a 4 year old split system Carrier that stopped working last week. The problem was the capacitor. I was given the choice between the "Chinese" capacitor with a 3 month warranty, or the "American" capacitor with a 5 year warranty for two hundred more. That is all the information my wife could get out of him (I wasn't home). I kind of figured the extra money was for the warranty, so I went with the cheaper one. Any one have any advice on this issue if it happens again? Thanks!!
