Aluminum fins

Eugene Silberstein 3

Adam, I've had good luck with Talon's line of coil cleaners. They clean all the junk off the coil, and whether the products claim they seal or not, I have noticed that the rate of new corrosion forming has been greatly reduced.

Here is the website:

Good luck and thanks for the kind words.

Aluminum fins

Firstly, welcome to the Wall! On behalf of myself and the other Wallies, it's great to have you and access to your expertise. We appreciate it!
Secondly, we installed a furnace and a/c system for a client's summer home in Jermyn, PA. We even installed a remote system so they can turn the heat or a/c on ahead of arrival to warm or cool the place. After the client covered the condenser with a vinyl cover over this past winter, there seems to be what looks like oxidization on the lower 4-5 inches of aluminum fins around most of the coil. While there for something else this summer, I tried dissolving it with vinegar but got no results. Any idea what it is or how to get rid of it?

Thanks in advance, Adam

Peeeeeeeeeeeeee

Unine fron pets which contains amonia will do this. I have seen it. I would never clean with vinegar as I believe it can be costic to. I know you stated that there was a cover on it, but Unine would be my first suspect!!!!

There isn't a sump pump discharge by the condenser is there?

I've got a customer that when his townhouse was built, the builder discharged his and his neighbors sump pump next to the condensers, and then the water softener discharge was dumped into the sump pumps. Next thing you know, the condensers were being exposed to the equivalent of a small hurricanes worth of salt water on a regular basis. Now the condenser is completely missing about 25% of the coil fins, plus major corrosion of the cabinet and compressor.
