"Don't include on lines 18a, 19a, 19c, and 20a any amounts paid for the onsite preparation, assembly, or original installation of the components." Not perfectly clear since there is a big difference between actual insulation in an attic and the Aeroseal process of sealing the ductwork from inside. Also, I couldn't get either company to itemize a cost of materials or tell me what percentage of the cost of the actual liquid used in Aeroseal as opposed to any other parts of the service. Technically there is no amount that was paid for any prep, no assembly, and no original installation since they only provide one price. Would the IRS themselves be able to answer this question with any accuracy? Do CPAs have a reference for this or would they just ask the taxpayer to give them the amount...washing their hand of the specifics? Opus 17, what would you do in this situation and are you familiar with Aeroseal? Thanks.
