      Mine is leaking from the side where the pump is and the water is kind of sticky and discolored. Had HVAC out and they found the water lines to be rusty “from condensation” like Angie Huk. They wrapped the lines and now 3 days later is leaking the same fluid???

      A just graduated hvac man told me the reason my minisplit was dripping water was because the line in the unit isn’t wrapped. He said he could see it and its bare,causing condensation. I’m having trouble believing that,as now of the experts said that. I’m having someone suction the drainage hie inside & outside today. But should I be worried about what he said ?
