    I told customer, let's leave it and put new RTU over duct-roof penetration.

    Whats wrong with that?
    I think the unit on the left is just sitting there. It was previously installed on the curb to the right, but they took it off and set it aside and put a new unit on.

    Bad Jobs

    I'm sure you have all seen the pic of the compressor bolted to a piece of plywood outside the condensing unit and piped in? Works

    Looks like the vent is pointing down towards the fresh air intake on the left hand unit....you are still blowing hot air into the unit regardless of gas or electric causing the system to work harder.

    I'm not a tech so I may be way out in left field somewhere.

    Is that an access door open on the unit on the right? In that case, there is a fine example of gravity cooling, the cold air dropping right down the return if that's the filter/blower section.

    Looks suspicious indeed. Could it be that the owner of the building informed hvac/r contractor to leave it on roof so it could be seen by insurance, warranty company, other. Probably more along the lines of a couple of guys not feeling like rigging another unit that day. Could be that Helicopter received call to replace Donald Trumps Rooftop, WHO KNOWS, but as you know you've seen it all until you get to work today!

    Nothing wrong with leaving the old unit on site for spare parts...

    Is that a tornado prone area?
