manholt Report post Posted July 5, 2018 Did you report it (hail damage) to your insurance company? Make, model and year of coach, brand of ac would be a big help! Share this post Link to post Share on other sites

richard5933 Report post Posted July 5, 2018 I bought a set of plastic fin combs from Amazon. It came with various sizes for different make/model of coils. Just have to be careful and go slowly so no further damage is done. Poke a hole into the tubes and it's all over. Share this post Link to post Share on other sites

richard5933 Report post Posted July 6, 2018 That's the set I use - works well unless the fins are severely bent over. In that case, I used a plastic butter knife to gently get them lifted a little so that the comb could get under them. Share this post Link to post Share on other sites
