"The same appliance made in 2005 is designed to fail in 5-7 yrs."
This is quite a statement. To say that something is actually engineered to fail in 5-7 years intentionally? You can back this up with proof right?
Yes surely modern appliances are built lighter then vintage ones were and there is far more cost cutting done to keep consumer pricing low. I think its a bit paranoid to believe that the intention of the engineers was to have the design fail frequently though.
Today's units _may_ have a reduced lifespan compared to vintage units but stating a 4 to 1 replacement is absurd. The frequent replacement is more likely more due to peoples decisions to fix/not fix and the state of modern service companies today. A 20+ year central AC is pretty rare no matter when it was made, most get replaced after 10 years, often for no reason. Twenty years from now there may well be just as many of today's units running as the the vintage ones are today, all depends on if people keep repairing them. For the record my AC is 22 years old at this point, I'm a "fixer". My girlfriends father just junked an 8 year old high end furnace because the draft inducer motor failed, he is not a fixer...
Replacing a working unit to get increased energy efficiency is quite likely a loser in the cradle to grave analysis. Only if the device is really inefficient would it make sense (like incandescent lights with LED, a 10 to 1 saving). When replacement is needed though, in general it does pay to pick the most efficient thing one can buy though.
