Carrier Heat Pump Model 25HCC5 – Approximately 4 years ago, I installed a new Carrier Heat Pump. Today, I installed the 3rd variable speed blower motor in 15 months. Although the blower motor is still under warranty, the labor is not and costs 600.00 each time. I emailed Carrier today to suggest that they consider extending the warranty on the blower, allow customers to replace only the modulator, the part on the motor that generally fails or install a better thermistor, the part that specifically fails on the modulator (a 2.00 part that leads to a 600.00 repair). I am now among the ranks of consumers that will not purchase another Carrier product and will share this opinion with anyone that will listen.
