About Ameristar HVAC Systems
Ameristar is Trane Technologies' budget brand, the lowest rung in a family that also includes American Standard and Trane. The equipment is built to handle basic residential heating and cooling at a price point where homeowners with tight budgets don't have to resort to unknown brands. The mechanical components are the same Trane Technologies-sourced parts used across the family. Serial numbers decode the same way as Trane and American Standard: position 2 is the two-digit year, and position 3 is the month as a letter.
