Common Mini-Split Drain Issues in Humid Houston
Because mini-split wall units pull heavy amounts of moisture from humid Houston air, their internal condensate drain troughs require regular cleaning. Microbial slime can plug the 5/8-inch drain tubing, causing water to drip down interior drywall. Clearing the drain line and treating the pan with biocidal strips prevents water damage.
