What about the vent here? Anything to discuss concerning the proximity to the unit?

I think what Joe was referring to was the proximity of the condenser unit to the vent in relationship to disruption of air flow.
Being that close, it may be possible for the volume of air being pulled in the side of the unit, and the air discharged out the top, may interfere with the proper operation of the vent. Per IRC 2426.6.5 and UMC 806.4 the vent has to be 2 feet above anything that is within 8 feet of the vent. If the vent was there first, then the condenser unit was installed too close.

Am I on the right track Joe?
