Air conditioner coils -- black fins

Black Paint ! Black mold. Yes it will help and you wont be breathing spores. Metal is a great conductor of heat , Plants are not. Be sure a mold killing cleaner is used,

I'm referring to the outdoor coil, which was definitely made black at the factory (brochure shows blackened coil), I'm sure for efficiency because the lower efficiency model has bare aluminum fins (same brochure). The indoor coil is shown as being silver colored for both models. BTW another reason indoor coils can be black is pinhole leaks seeping out oil (vertical streaks).

None. Todays higher end models are using non painted coils...

I take it you're talking about the outdoor coil?

The color will have no effect on the coils. (as long as the aluminum isn't deteriorating)

Black absorbs more sun shine. So, black fins have a negative effect on an AC.

BTW

Really? I would expect the unit to fail from lack of refrigerant long before enough oil leaked to give that effect.

Stormin, quit talking about something you know nothing about.

Have you knock in any doors lately?

I heard you were a so called 'locksmith' but you couldn't pick the lock, so you pushed the door in!

And I don't need to say anything about the HVAC aspect, cause I already know you know very little on that subject.

But, I do have a question for you,

Are you and Davey 'HVAC fella' brothers??

Hey, lets go to the desert some day on a sunny day. I'll wear white clothes, and you wear black clothes.

Logic and physics agree paint reduces heat transfer and black will absorb solar radiation. Whether it can be rated on an AC? Paint a piece of wood black, one silver, the black at 0 f wil be 50-60 in calm full sun , the silver under 10f. Ive done it. At 80f black will be over 120 silver near 90f Paint reduces heat transfer, but type of paint and thickness determine amount. Maybe on old cheaper units it was done ? Measurable amount of loss ? But I would think so. Just as I wouldnt put a unit in full sun where temperatures are 20-40+ hotter. It doesnt matter some will say , well then why are newer shakers flipping water back into the coils. I have a lake 20 ft away I wish I could submerge my coils in 20ft of 60f water, I figure every little bit helps.
