Before work is authorized, ask for the design method, AHRI match where applicable, installer or dealer qualification required by the manufacturer, registration responsibility, parts coverage, labor coverage, exclusions, and current incentive assumptions in writing. Those details vary by model, project, contractor status, installation date, and current program rules.
