The state board's job ends at the license. Ours starts there.
HVAC licensing varies by state: different rules, different registries, different data formats. Most state boards don't surface contact info at all. ContractorRoster normalizes the data and delivers every active HVAC license in your market with phone, email, and website in one clean CSV — in under 3 minutes.
Delaware: Delaware licenses electricians, plumbers, and HVACR contractors through the Division of Professional Regulation, and every other contractor working in the state holds a Division of Revenue contractor business license. Both rosters are published as state open data, refreshed daily. Phone and email aren't in the state files, so we fill them from public sources; business-license records carry the full street address. Out-of-state firms licensed in Delaware are excluded from these results by default so you see in-state contractors first.
