Corrosion on Condensing unit fins
 

LIttle 2-ton Heil R22 system, 1 1/2 years old. Cools tiny brick
bungalow in midwest US.

Dogs are all female: no peeing on unit. I hose it down every
time I run the weed-whacker.

Condensing unit fins near ground level turning grey/white with
some kind of corrosion. Doesn't look nice, couldn't improve
heat dissipation.

Spray the corrosion with some kind of preserving lubricant?

Thx,
Puddin'

I think it's oxidation of the metal, probably aluminum. Don't really know
if you need to be concerned about it interfering with the operation
especially if it's on just a couple rows of fins.


If you are spraying with hard water - STOP!
it is probably deposits from the hard water.
Only use soft water.

Nooooooo problem.

I'll start building the still in the back yard tomorrow.

Run it half-time for the soft water to clean the CU. Other
half for that "Good Cohn Likker".

Kill 2 boidies with one stone. Eh?

Corrosion on Condensing unit fins
 

Aluminum is a reactive metal protected by oxide.
However when corrosion occous it can literaly
lay the copper coil bare.
You should have the coil coated with a polymer
This can be brought in spray cans and goes
under various names Kole Kote Etc.
