Renamed Arena Will Always Be Verizon Wireless Amphitheater To Locals Hopeless Resignation Receives Massive Post-Debate Bump Hopeless Resignation Receives Massive Post-Debate BumpWritten My first thought was, "Why would they innovate?  Has there been a radical shift in the construction of windows?  Would the exteriors of houses built today be barely recognizable to someone from the '80's?"  Of course not, so why change?Then I thought about it more.  The reason you see no "innovation" in the window AC is because it is an entry level product for that market.  If you live in an apartment or small house without A/C, your first step is a box fan.  Your second step is a window A/C.  When you have the funds, you either move up to central air, a minisplit, a PTAC or some other permanently installed device.Therefore, the key to selling window A/C units is to make them cheap.  Similar to what I wrote in the question: Why are window air conditioning units so loud?, they could make a fashionable, quieter...whatever you want but in the end if it is $40 more expensive than the competitors, the majority of the market will buy the competitor's unit.

My second answer is that you are simply wrong.  There have been major changes in the manufacture of these devices, its just happened gradually over time and mostly internal to the case.The biggest innovation has been the increase in efficiency of the units.  Of course, most of this was mandated by the DOE.  Even so, many window units rival central air in energy efficiency.  But this isn't seen from the outside.The other big one is in refrigerant selection.  Many units have traditionally used R-22.  Since 2010, that has been phased out causing a radical re-design of the refrigeration system.  Again, something you can't see from the outside.There are many subtle changes you don't catch, as well.  Believe it or not, those units have gotten smaller.  Or maybe the cabinet is the same size but the refrigeration capacity has increased significantly.  So it can cool more space.The weight has dropped significantly.   In the spring I help my folks put in two units.  The first is a dinosaur from the 80's. 

It takes two people and a lot of grunting.  The second is less than 10 years old and can be hoisted into place by just myself.Finally, really think hard back to the 70's and 80's unit.  On the inside, it probably had some sort of fake would paneling that would flip up to reveal the controls.  As you showed, there aren't many of those on the market.  They are all now the "sleek/industrial" look, which is of course cheaper to produce than the faux wood panel look.Written There has been innovation over the years with the SEER (energy efficiency).. Are you referring to the design of it? : Quirky + GE Aros Smart Window Air Conditioner: Home Improvement). The AC world is innovating every year. I just bought this mini split unit with a crazy high SEER and works with my smartphone (GREE Crown 9,000 BTU Ductless Mini Split Heat Pump System - 30.5 SEER (208/230V) Smart-home tech is becoming more popular every year.
