Condensor fins fell off while cleaning
I've cleaned thousands of window units but today was different. With the unit in place and unplugged I sprayed the bottom of the condensor coils with a foaming-self rinsing cleaner. I only sprayed the bottom, about 2-3 inches. This was the area that was dirty. It was very dirty. Even though it was self rinsing I went ahead and rinsed with the garden hose. The fins just fell off, but only where I sprayed cleaner and applied water. I had cleaned 2 units earlier that day with the same cleaner and no problems. Was it just so really dirty that they eroded away? The A/C is operating properly now with a 20* temp change. Before is was only 11* but the bottom 2 rows of coils have no fins, plus there are no leaks.
Is this a good question?
