Can we use split AC when water is leaking?

Operating a split or ductless mini-split air conditioning system when it is actively leaking water is strongly discouraged and should be avoided until the underlying drainage issue is fully resolved. Continuing to run the AC will only generate more continuous condensation from the indoor evaporator coil, exacerbating the leak and causing pooled water to overflow the drain pan, leading to severe structural water damage, ruined drywall, warped flooring, and potential electrical short circuits in the wall cassette. You can troubleshoot by checking for clogged drain lines or a full condensate pump. You can verify that the system is safe to operate when clearing the blockage, flushing the drain hose, or repairing the pan stops the water leak completely and routes all condensation away safely.
