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

1. Yes

2. No

3. It depends on the size

4. Only if mandated by local code

The correct answer is: No

The requirement for a duct tightness test is influenced by the location of the air handler and whether it is situated in a conditioned space. When an air handler is located within a conditioned area, it is generally not necessary to perform a duct tightness test, as the air is already within a controlled environment. The purpose of duct tightness tests primarily revolves around ensuring that systems located in unconditioned spaces do not lose energy due to leaks in the ductwork, which could compromise efficiency and performance. In cases where air handlers are in conditioned spaces, the focus shifts from duct leakage to ensuring proper airflow and functionality within that space, as any leaks would not directly impact the energy efficiency of heating or cooling the space. Therefore, the answer indicating that a duct tightness test is not required is appropriate in this context, as it recognizes the circumstances surrounding the air handler's location.
