I am in the process of replacing my 17 year old, no name 5 ton central air unit. The air handler is in the attic. I had planned on using the same line set since the unit unit will also be using the r-22 refigrant.

One dealer had a problem with my current line set. The current size pipe for the 5 ton unit is 7/8 in. He is telling me that it should 1 1/8 in. He wants to replace the entire line set. All the other dealers tell me the current piping is OK.

I would appreciate any comments on if the existing piping is OK

It adds extra cost since the new pipe will need to go up the side of the house into the attic.

Your answer helped me understand that the orignal installer did nothing wrong 17 years ago. He used the correct pipe at the time.
