I build a new home in 2006. The builder installed a Carrier Infinity furnace and air conditioner which cost over $11, 000. In June 2011, the blower motor and module on the furnace failed. Carrier would not honor the 5 year warranty because they insisted the warranty began in April 2006 when the builder installed the unit. The house was not completed until October 2006 when I moved in. I thought they should honor the warranty since it was only two months out of warranty according to their start date but they refused. I then tried to argue that the warranty should have not started in April 2006 since it was new construction and the house was not completed until October 2006. Again Carrier refused. To make matters worse, the replacement motor and module has only a one year warranty even though the cost is nearly $2, 000. Consequently, I will never buy another Carrier furnace or air conditioner. When the time comes to replace the furnace or air conditioner, will consider another brand such as Lenox or Trane. The service company that serviced the unit stated they no longer recommend Carrier because of their poor quality and recommended Lenox or Trane.
