A Yes
Q The SOW of work states that the contractor is to flush the existing line sets and blow out any existing oils and debris with compressed nitrogen. According to manufacturer specifications from several manufacturers it is not recommended to use existing line sets that have had r410a in them with the new refrigerants that need to meet the new EPA standards such as r32 or r454b, this may void any factory warranty.
