Then the air is pushed outside as heat
Some technology that costs more money isn’t necessarily better or improved over their cheaper counterparts. I learned this fairly quickly as I kept upgrading my smartphones year after year. The phone manufacturers convince you that the new model is necessary with a handful of various upgrades over the previous iteration. But time and time again, I found that each new phone would lose some of the things that I liked about the previous one. Once I finally realized that these “improvements” are just minimal changes to justify rereleasing the same device at a higher price each consecutive year, I quit upgrading my cell phones until something happened to make them quit working. These issues abound in other industries as well. Many people will tell you that you need to upgrade your window air conditioner to a portable unit if you haven’t already. They see the higher price for portable air conditioners and their ease of use as two factors proving their superiority over window units. Sadly, this is borderline smoke and mirrors when you compare it to other misleading attempts at marketing. A portable air conditioner in its original form is inefficient because it needs to pull cool air from your home and use it to cool its internal compressor. Then the air is pushed outside as heat. Window air conditioners already have their compressors outside the window, so this is a self-inflicted design flaw. Two-hose portable a/cs are better because the air used to cool the compressor is pulled in from outside, but it doesn’t remove their inefficiency completely.
