Texas regulators issued updated statewide guidance this month clarifying commercial refrigerant leak detection requirements for systems undergoing the A2L transition, aligning state enforcement expectations more closely with the EPA's federal AIM Act thresholds. The guidance specifically addresses systems in the 15-to-50-pound refrigerant charge range, a category that has created confusion for commercial refrigeration and light commercial HVAC contractors statewide.
Why this matters beyond Texas: when individual states issue their own interpretive guidance on top of federal AIM Act rules, contractors operating across state lines — or distributors serving multi-state commercial accounts — face a patchwork of slightly different compliance expectations even when the underlying federal rule hasn't changed. Texas is one of the largest commercial HVAC and refrigeration markets in the country, so its interpretation often becomes a reference point other states watch closely.
The practical change for contractors: leak detection device placement and inspection interval documentation now need to explicitly reference the updated state guidance language on service tickets and compliance files for any commercial system in the affected charge range, not just the federal AIM Act citation contractors have been using. Distributors supplying leak detection equipment in Texas should confirm their product specification sheets and installation guidance match the new state language.
For commercial refrigeration and light commercial HVAC contractors working in Texas, the near-term action is straightforward: update standard operating procedures and technician training materials to reflect the new guidance before the next round of state inspections, and flag any commercial accounts with systems in the 15-to-50-pound range for a compliance documentation review this quarter.
