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.

Common Failure Modes
The compressor or fan motor are the most common mechanical failures. However, most units are discarded because the sealed refrigerant system develops a micro-leak, making repair uneconomical.
