Our Methodology

How we collect, verify, and maintain HVAC contractor data across the United States.

Data sources

We source listings from state contractor licensing boards, public business directories, and business websites.

Freshness

Each listing is labeled fresh (checked within 6 months), aging, or stale. This helps you know which data may be outdated.

Claimed vs unclaimed

Business owners can claim and review their listings. A claimed badge means the owner confirmed the details.
