The correct installation determines the life of the unit. Shortcuts are made because of time constraints or lack of knowledge or apathy. IMPO

I have been told dozens of times that AC units in Florida only last an average of 10 years. I believe this is accurate as I watch most of my neighbors having their AC units replaced at about this lapse of time. You do present some valid points BUT, there are differences. One of the main components that fail are the cooling coils. Several years ago cooling coils were all made of copper. In today's units the coils are now made of aluminum and much thinner than the copper coils.
