Customer complaint: Furnace louder than usual. Upon arrival, identified loud noise coming from the inducer motor. Checked amp draw on the inducer motor and blower motor—found the inducer motor drawing excessive amps and hot to the touch. Advised customer that the inducer motor needs to be replaced. Performed a cleaning and full safety inspection since no prior maintenance had been done. Recommended replacing the flame sensor as well. Noted that the furnace had a new heat exchanger installed in 2016. Performed combustion analysis, confirming the heat exchanger is currently safe. Advised customer that the venting is older (black abs,grandfathered in) and requires yearly inspection. Customer was on a conference call and unable to discuss the option of a new furnace, but advised that given the prior heat exchanger replacement, they should weigh the pros and cons of further repairs vs. replacement. Furnace is safe at this time, but inducer motor replacement is needed.
