As an update to what I posted earlier, I contacted the company that did our Aeroseal and they sent me the documents and told me that the entire Aeroseal process could be deducted. Until the Instructions for Form 5695 give more specific guidance, this will continue to be a gray area. I was also given advice by the other company to simply send the info to my CPA who "will know how to handle it". Yeah sure.
I would not trust a heating contractor to prepare my taxes, I'm glad you have confidence in yours.
The instructions for line 18a are quite clear.
Don't include on lines 18a, 19a, 19c, and 20a any amounts paid for the onsite preparation, assembly, or original installation of the components.
Line 18a.
Enter the amounts you paid for any insulation material or air sealing material or system (including any vapor retarder or seal to limit infiltration) that is specifically and primarily designed to reduce the heat loss or gain of your home when installed in or on such home and meets the criteria established by the IECC.
