Why US Cost Index Data Outperforms Generic Cost Blogs
Most internet home improvement cost guides reuse outdated 2018 contractor surveys. US Cost Index calculates every estimate algorithmically by synthesizing 4 authoritative public registries:
Every quote incorporates current regional loaded wages for certified mechanics, factoring local cost-of-living differences.
Heating and cooling loads scale automatically using Building America climate maps (HDD and CDD values).
Operating cost and 10-year savings projections dynamically calculate using actual state-by-state utility rate tariffs.
Qualifying all-electric heat pump systems immediately reflect up to $2,000 in federal tax deductions.
