Aside from visually being plastered everywhere, what do you make of the spray foam sealant in terms of a deficiency? There’s gotta be a write-up for this I would imagine. I already have the wrapped tape on record for the suction line. Thanks!
It is better than nothing.
I note it as not durable enough to be used outdoors without some protection. Usually after a year in the sun it becomes quite fragile. Even just painting it helps with that.
Welcome to the forum Brian!
Expanding foam is not intended for this application and does not age well when exposed to the elements and UV light from the sun. All exterior penetrations like this one should be sealed with an appropriate elastomeric sealant (caulk/butyl or other).
Thanks, Tony - happy to be here!
I appreciate the insights, everyone - I’ll suggest a better-suited sealant for this application and/or annual maintenance with a protective coat.
The foam may stop bulk rain from getting in the wall and could be trimmed and painted, but outside air will still be getting behind that siding and condensation from the presumably uninsulated suction line within the wall will wet the sheathing and framing inside the wall around the hole. At least that mess warrants passing it off to HVAC people.
Welcome to the forum, Brian.
The latex paint on foam works out OK for durability. Without it, the foam is toast.

Thanks again and also for the “welcome” messages!
