Condensate leaking from bathroom vent. Air handler and secondary pan both install wrong and not leveled correctly. Condensate from unit not flowing correctly due to unit not being installed properly causing condensation to go into secondary pan. Pan is not installed properly to slope towards drain hole. All condensation is flowing straight to back on pan and overflow into attic causing leak in bathroom. Advised homeowners of findings and best solutions to resolve issue. Homeowner decided to go with new pan and float switch replacement. Also noticed some bad duct work and detached duct work recommend Enery Audit to homeowners. I did get some water out of pan and away from where overflow was coming from.
