Lumber and Siding - How to cover AC tubes

I just sided my home with vinyl siding. I capped my home with white aluminum. My only problem in figuring out what to do with my AC lines.

They go from the condenser straight up my home about 10 feet and into the attic. Some people put a backless gutter over the lines; however, because I have ductless units, I have two sets of lines that sit side-by-side. There is a set of electrical lines and copper tubes covered with pipe insulator for each unit. So the thickness of the lines that need to be covered is about 8 inches wide and about 3 inches deep, which likely can't be covered by a single gutter.

Is there any way I can cap these lines or cover them professionally?

Any advice would be appreciated.

Thanks

Here the installers often have a sheet metal shop make up a cover of appropriate size. You could then paint it.

I agree with Ray, they are usually square open back boxes with flanges on the sides that will slip under your j channel on the sides of the chase and nailed discreetly on the way up. They can be painted or color coordinated with stock coil.

Another way, which would leave the lines exposed, would be to insert a strip of trim coil about 10" to 12" wide behind them and then install "J" channel up both sides that your siding would end in.
