Average lifespan
Window AC units undergo heavy seasonal stress. With proper filter cleaning and winter storage, they provide years of reliable cooling.
Error: FL (Filter Alert)
The unit has tracked a set number of run hours and is reminding you to clean the filter. Clean it, then hold the reset button.
Error: E8 / Overload Protection
The compressor has overheated, likely due to a frozen coil or blocked airflow. Turn the unit off, clean filters, and let it thaw before restarting.
