Just noticed this when getting a new AC installed yesterday. Not sure if it's a bird or squirrel nest, or even active. It's super high up that I don't have a ladder to reach, also I am not super cool with being that close to electrical wiring but I feel like it's a hazard that needs to be removed. Anyone else experience this and what you suggest my approach should be or what service might need to be hired?
Wait till winter so that you don't mess up with this year's reproduction process.
