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'
