I remember years ago when I sold my laptop to buy a modern ipad. I thought that I was spending money on an update in features and capabilities from one component to the next. Somehow I didn’t get the memo about the limits of mobile devices and their operating systems. For one, I was moving from Windows to an apple mobile operating system. Moving to any kind of apple operating system would always entail a loss of features for me. I use a lot of software that is only accessible through the Windows platform. Sure, the tablet had a fairly large app store, even though I had to compromise with mobile software. Some applications are amazing while others can be unstable, if not outright unUSble. I had a similar episode with my a/cs in my apartment. My condo is a single home office condo with a large home office and home office. Before I decided to attempt an update with my HVAC equipment, I had one window a/c in my home office and another in the home office near the entrance to the home office. At first I decided to buy a brand modern portable a/c and put it in the home office. My intention was to eventually buy a hour portable a/c to update the window component in my home office. I had read that portable a/cs had many features that window units lack, and I naively assumed that meant portable air conditioners were better machines. They’re severely inefficient with energy use and they recycle conditioned air to cool their tepid compressors inside the same metal enclosure as their frigid evaporation stage. These components are intended to be separated for a reason—that’s why compressors are put outdoors in all other HVAC systems.
