Corrosion of condenser fins


yeah, what size is the existing liquid line? if it's 1/4 it's too small. new liquid line drier?

If you paid for it, you should get it. Dont be intimidated. Isn't the new system 410A? I thought you could not re-use R-22 parts for R410A

Corrosion of condenser fins


a lineset is not a part specific to any refrigerant. it can be nitrogen and rx-11 flushed to remove any and all old chemicals and oils, made like new again.

we do it all the time.

Heck, I just blow them out with nitrogen. Chemical flushes are mostly a waste of money and time.

Corrosion of condenser fins


The existing line is 5/16 inch. He left that original run in place and attached it to new 3/8 inch at the condensor and evap coils. He tested to pressure and said it was fine.

I'm conflicted- replacing it could well cause a leak. So if 5/16 is ok for that system, I say fine. I just wish he would have contacted me and told me what was up.

I have no idea how he prices his jobs. I will tell you I paid him $2700 for the job. What is fair value for around 25 feet copper line? No clue. Nor do I know what his labor would have been to replace it- maybe an hour tops?

Anyway, I'm inclined to let this one go as I imagine we're not talking much money. Serves me right for not being present when he was installing.

Damn you career!

I also wold have installed 3/8 if there's a 3/8 dia. connection at the condenser. I always install the size that's specified at the condenser unless it's a longer than normal run the I will think about increasing the dia.

I never install a smaller than what's at the condenser.

That means all the way from point to point.

Thanks Doc, more BS just to sell stuff. Once again, common sense rises to the surface.
