Arrived onsite for condensate leak. Homeowner mentioned it leaked last year too. Homeowner vacuumed emergency drain pan. I cleaned the condensate trap. Used CO2 cartridge to blow air through the primary and secondary drain line. Pour water in the evaporator coil drain and observed proper drainage. Upon testing the emergency drain pan found a hole in the pan. Used silicon to seal the hole. Homeowner will contact us if silicone doesn’t hold. Recommend annual maintenance.
