What is the average lifespan of a rooftop A/C unit?
Our bedroom A/C has stopped blowing cold air, just blows room temperature. Motorhome is a 2012 and we've full-timed for 6 years so we've used it the whole time. Thanks in advance.

2005 unit purchased unused in 2009. Roof air still works well--but I try to avoid having to run it.
