Upon arrival client showed me to Indoor Ductless system, mentionted that system has been leaking. Says construction was is also being done in area near unit. Checked filters heavily restricted, washed filters, tested primary drain pain with water multiple times noticed drain is slowly dripping water. Went to outdoor unit, vacuumed condensation line, went back inside and tested primary pan again noticed water is still dripping. Must return 2 Technicians to remove indoor unit and inspect drain line connection going through wall, and also inspect primary drain pan. System is currently still slowly dripping condensation. Office will contact client regarding return visit. Reviewed work completed with client.
