HVAC standards and installation practices vary by region across the country to meet the many needs of different regional temperatures & humidity, project types and local building practices. This variety in system design and specification is one reason why standards have been designed and adopted to ensure HVAC systems are built to specific criteria to provide consistent performance based on their needs.
