Arrived to remedy a system leaking condensation. Upon inspection of the system found condensation leaking out of the highest points of the PVC drain. Opened up evaporator coil and made sure condensation was not backing up into the evaporator coil. Installed gel tabs to eat away the bacterial growth, causing this issue. Opened up PVC drain and attempted to clear the restriction with the shop vac. When this failed took the PVC drain outside and jetted it out with the hose. Reinstalled PVC drain and ran a flush. System is functioning properly at this time.
