HVAC duct manufacturing requires precision and attention to detail to achieve optimal performance. Avoid common mistakes such as inaccurate measurements, improper sealing, inadequate insulation, and incorrect duct sizing. These errors can compromise airflow, decrease energy efficiency, and lead to discomfort or even system failure. Additionally, ensure proper material selection and adhere to industry standards during fabrication. By avoiding these mistakes and prioritizing quality control, you can ensure the successful production of ductwork that delivers optimal heating, ventilation, and air conditioning performance
