Is a duct tightness test required for an air handler located in a conditioned space?

1. True

2. False

The correct answer is: True

A duct tightness test is indeed required for an air handler located in a conditioned space to ensure that the ductwork is well-sealed and functioning efficiently. This testing is essential for maintaining indoor air quality, energy efficiency, and system performance. When duct systems are not properly sealed, conditioned air can leak out, causing the system to work harder to maintain the desired temperature. This not only increases energy costs but also may lead to uneven heating or cooling throughout the space. By performing a duct tightness test, contractors can identify and rectify leaks or inefficiencies within the duct system, thereby enhancing the overall effectiveness of the HVAC system and ensuring compliance with local building codes and standards. Understanding the necessity of duct tightness tests contributes to the overall success of a HVAC project and reinforces the importance of best practices in installation and maintenance to provide comfort in conditioned spaces.
