## Data source and method

Every number on this page comes from one scan of public local business listings in Maryland, taken on 13 August 2026. Nothing is estimated and no empty field is filled with a guess.

- **Source:** Public local business listings, read city by city on a fixed schedule.
- **Counting rule:** One record is one physical location. A chain with eleven depots is eleven records, not one. A business is counted in HVAC contractors when that is its primary listed activity, not when it merely mentions it.
- **Scanned:** 13 August 2026
