How to read these scores
Each window ac gets a rating out of 100 on each row of the benchmarksutra AC Score, and a buyer profile weights the rows. Tiers: S 90+, A 80–89, B 70–79, C 60–69, D below 60. Where a maker page does not state a spec, we leave that row out and re-spread the weights; we never guess. Read the full method.
