We spent $9000 on a new Trane heat pump/AC unit for our home and it stinks! Trane is considered a top unit, but it is not worth the price! It never works properly! Constantly needs servicing! It shook so hard last winter that the top bonnet cracked & Trane would not replace it, saying something must have fallen on it! There is nothing near it to fall on it! They just don't stand behind their product! My advice, if you need any heating/ac units, buy anywhere but TRANE! Cheap product for high price!
