A ductless mini split is much more energy efficient than a portable air conditioner

Portability is not always better.

When laptop computers became more affordable in the late 1990s, many people switched to that format.

This was after years of desktop computers being the mainstay in both residential and commercial applications. The promise of a computer with all of the same features that you could take with you on the go was tantalizing for many people. But like all computers at the time, laptops were often prone to failure. My sister’s first laptop was prone to the ‘blue screen of death’ on a daily basis, crashing in the middle of something as trivial as writing a quick email. I had a tower PC that lasted for 15 years without problems, but all of the first laptops that my family members used were mostly junk. Thankfully, newer laptops are solid computers that last much longer than the ones from 20 years ago. Some portable products are completely junk, no matter what you do with the technology. I tell people that portable air conditioners are a racket. They’re not just slightly undesirable, I genuinely feel like the person who designed them did so with the intent to scam and con people out of money. Anyone with a basic understanding of air conditioners knows that the technology works as a split system, and that’s true even with a package system. What I mean is there is an evaporator coil that gets really cold as refrigerants liquifies inside. The refrigerant absorbs your indoor air’s heat and then takes this heat energy to the hot compressor outside. The refrigerant becomes a gas at high heat before being pulled back inside to become a liquid once again. It’s a circular process, even in a window a/c. But a portable air conditioner has its hot compressor inside, meaning all of the heat energy just goes back into your house.
