Technician arrived to perform a yearly friends and family club furnace maintenance on a 2008 Concord furnace. Technician adjusted gas pressure, checked amps, checked static pressure, checked temperature differential, cleaned flame sensor, changed filter and insured proper operation. When starting the furnace, the inducer motor bearings were very loud and technician made estimates for the customer on getting it replaced. Technician also noticed dirty ductwork while changing the filter and made estimates on getting the ductwork cleaned and sanitized. Customer did not want to move forward with any estimates at this time, but they have been emailed to her. System is heating properly.
