My heatpump made a loud noise which wake me up at 3am. Unfortunately I did not get a call back until 7am and the tech was able to guide me in the right direction to turn on Auxiliary heat. He was able to come out later that morning and confirm that the fan was indeed dead. He gave me a quick estimate which required more research and was able to connect me with their Sales person to help inquire about a new system since mine was just over 14 years old. He was straight forward and able to replace my fan assembly the next day.
