So many people are having AC problems or worse, the units completely die and have to be replaced. Ours was 12 years old and died this Spring. We were fortunate that it happened when temps were still comfortable, but not so fortunate that is cost us a small fortune to replace the WHOLE system.
It also took the an entire day to get the job done. One crew comes out to rip out the old system and another crew comes out to install the new one. It's a big job so be prepared to have some at home all day, or at least tag team it. 4951
