For this evaluation the customers complaint was a burning smell coming from the furnace and the system wasn't cooling. Upon inspection it appeared the coil had frozen up and the blower was making a loud humming sound and not running. The blower motor had power however was barely spinning, indicating the motor bearings were seizing up in addition to running extremely hot. The system is a 2006 straight cool, and with the age I spoke with the customer about his options which he elected to just replace the blower motor at this time. I explained to the customer that when I replace the motor I cannot guarantee there won't be other issues to follow and my overall recommendation would be system replacement.
