Occasionally I’ll come across this configuration. The extrusion here contains a factory built fire place. The issue here is that we have a small roof structure, with a gutter but no downspout. The gutter has a small slit on the right hand side that discharges directly into the air-conditioning unit. Over time, this water intrusion will cause damage to the unit.
I have seen this is several parts of Ottawa, it’s important to control water in and around your building.
