Hello, I recently inspected a townhouse with the A/C on a flat roof. The coolant line ran into a vent on the gable part of the roof. Has anyone seen this before? Is it correct? The vent was only used by the coolant lines and there was another vent for the plumbing. Also the line ran 3 stories down to the basement. I’m getting heat from the sellers agent and would like to know if I screwed up.
