Neglecting to clear or maintain your air conditioner's drainage system results in water accumulation that can trigger automatic safety shutdowns or cause catastrophic water damage to your home. When condensation cannot escape through the clogged PVC pipe, it fills up the primary drain pan and spills into the secondary emergency pan. If the water level rises too high, a safety float switch will trip and disable your cooling system to prevent indoor flooding, leaving you without air conditioning. If no float switch is present or if it fails, the overflowing water will pour down into your ceilings, walls, subfloors, and electrical fixtures, leading to costly structural repairs, ruined drywall, and hazardous black mold growth that poses serious indoor air quality and health risks for everyone living in the house.
