I would use a window a/c over a portable air conditioner regardless of the application

There are some products on the market that bill themselves as premium upgrades to older technology, but then fall short of their promises.

Copper coated cooking ware is one example that comes to mind.

I saw those commercials where the announcer claimed they were capable of total-nonstick cooking at medium to high heat with no oil or butter. They’d literally pan-fry a slice of cheese and then flip it to show the pan’s capabilities. But then the manufactured pans had a lower quality-control put into them and many people like me were disappointed when they couldn’t outperform our ceramic coated cooking ware. I guess the few people who were lucky enough to get good pans were happy, but they were outnumbered by others who purchased defective products. It’s smart to remember that something isn’t better simply because it touts itself as an improvement upon its predecessors. If you actually believed the marketing hype around some portable air conditioner models and manufacturers, you’d think that they are these wonder machines that outperform window air conditioners with much easier installation and maintenance. Unfortunately, portable air conditioners create new problems that don’t even exist in the first place with tried-and-true window HVAC units. Window a/c units and split-style HVAC systems place their hot compressors outside of the home. With the former the compressor is right outside the window, in the latter it’s in a metal enclosure outside. Portable a/c units have a compressor inside the machine and your home, which creates heat while cooling some of your air. To offset the heat, some of the cold air is recycled to cool the compressor and it’s blasted outdoors as waste.
