Guide · Air ConditionerStanding water in the base pan, slime on the coil and a dirty blower wheel cause most odors. Units tilted wrong or stored wet are frequent offenders.
Guide · Air ConditionerIn humid weather or dry mode, a portable can collect water faster than it evaporates it. Drain and set up a continuous drain first; a code with an empty tank points to the float switch or internal pump.
Guide · Air ConditionerIndoor head leaks are almost always drain related: clogged pan or line, poor line slope, a failed condensate pump, or the head not level. Ice on the coil from low airflow or low charge is the next suspect.
