Arrived on site and checked in with customer. Inspected upstairs air handler for noise and water issue. Found noise was coming from a slip of card stock wedged within the blower housing. Removed paper and noice ceased. Discovered that primary and secondary drain had been switched and unit was draining directly into the garage. Changed routing of lines back to proper locations, primary drain will now lead outside. Checked system operation and found it within range. System operational at the end of service, issues resolved at this time. Bill install.
