BTU capacity is generally the biggest factor in how heavy a window AC is.

But beware when buying a window air conditioner based on capacity. This is because heavy models in any given capacity can weigh 30% to 50% more than average for units in that capacity. Some weigh up to 75% more than the lightest models.

For example, the heaviest 12,000 BTU window AC weighs 42% more than average and 82% more than the lightest 12,000 BTU window air conditioner.

The single lightest window air conditioner is the Keystone KSTSW08A, and yes, it weighs just 30lbs. 

However, please note before you buy that this is a casement window air conditioner. That means it will not fit in many single-hung and double-hung windows, only casement and sliding/gliding windows.

*The Keystone website lists this unit at 35.5lbs. That weight likely includes the packing materials. Once you unbox the AC, it should weigh about 30 pounds.
