    Sealing goop?
    I am not sure how best to describe my request. What type of material should be used to seal where the copper tubing, electrical, etc, enters the home from a central air conditioning unit. It looks like the contractor/former owner, just slapped up a very thin layer of cement, but it seems really insufficient. If it matters, we have a brick home.

    Thanks!

    Sometimes people just use caulk, or a product called duct deal. Look around Home depot or Lowe's I am sure they have something that will work.
