I just moved into a house beside a friend, and I notice his outside a/c part has some issues, so any experts out within.maybe you can inform me if this is normal, is it a cheap a/c section, or something that's covered under warranty. It's over 9yrs outmoded and I just found out the ten yr warranty is almost up.

I purely sold my house and had a/c problems so I'm a bit familiar. I do know the fins are supposed to be straight; mine be, and looked like a solid metal. That section was 11 yrs frail.

Thanks!

i would basically try to vacuum all the crud out of nearby and keep on using it till it doesn't cool anymore.
those fins are in that to help cool down the hot gas that go through the tubing. you enjoy the same type fins and tubing on the inside the house that help spread more cold air.
