Is a $300 portable AC better than a $150 window unit?

No — a $150 window unit is more efficient and quieter. Portable ACs exist for situations where window units aren't possible (crank windows, HOA restrictions, rental agreements).

How long do budget portable ACs last?

Typically 3-5 years with regular use. The compressor and fan motor are the main failure points. Clean the filter monthly and store properly off-season to maximize lifespan.
