A continuation of the solid skills development and strong theoretical knowledge established with HVACR 101 and HVACR 201, this third installment in the series guides readers through increasingly advanced concepts in the field. Like the rest of the series, HVACR 301 is backed by the high standards and cutting-edge resources of the Air Conditioning Contractors of America (ACCA), Plumbing-Heating-Cooling Contractors – National Association Educational Foundation (PHCC Education Foundation), and Refrigeration Service Engineers Society (RSES). Coverage ranges from the troubleshooting of systems and components to concepts of fluid handling systems, cooling towers, and indoor air quality.
