inner coil failure
We moved into our house in 2007. 10 months later, the air conditioner failed to cool.The inner coil had to be replaced. Since then, the coil has been replaced 5 more times. The company that installed the unit can not figure out why this is happening. We live in a tract home (all built with the same materials), have no animals, don't smoke and don't brew drugs. The house is clean and we change the filters. Does anyone have any idea what might be causing these coils to fail? Please help!
