I had this AC system installed, and didn't realize when asked about what location i'd prefer the compressor that it would look so ugly having it off the corner of the building instead of in the middle (due to the AC lines). The return line and electrical conduit are rather large and look rather unsightly as you can see. There was no option of making the lines exit the building right behind the unit without doing A LOT of drywall and interior reconstruction. My front steps are about 5ft to the right of the picture. So this ended up being an eyesore. 
Suggestions as to how I make this not look so hideous? The AC installer suggested I get some tin roof gutter and afix it sideways so to cover this. Seems like that would be just as ugly.

There are a few options.
You can get some brown gutter downspouts, cut out the back end and mount it over the pipes. I think the downspout will look better versus the gutter because of it's uniform shape. This is commonly done in my area but it is installed at the same time as the pipes so that the pipes can run through it without having to cut the downspout to mount over the pipes.
The brown downspout will be less noticeable but if you want you can try to paint it to match the brickwork.
You can plant some shrubs in front of them.
Or you can do both.
