Upon arrival system outdoor system had a hpc cut off activated Reset and operated system, at first refrigerant levels showed over charge, removed dirty filter and refrigerant levels went back to normal. Also had a fault code of wet switch activation, customers drain was backing up per the looks of it, they Snaked and cleared themselves before I arrived, checked drain with 3 gallons of water and drained acceptable. System is operating efficiently explained to cust they need to change their filter asap System was cooling as I left them home cust agreed
