Clean Window Air Conditioners in Spring
A window air conditioner can hold some nasty surprises after winter storage. Aside from harmless stuff like dust and dead bugs, it might contain health threats like mold or mouse droppings. So before you lug it to a window, vacuum all the surfaces, especially the fins on the exterior face of the unit (that’s good for efficiency and performance, too).
Also pull off the cover panel, and
vacuum and clean the foam filter. Finally,
plug it in and fire it up. Better to blow dust
around the garage than your bedroom.
