Nate Core Practice Test 2026 – Comprehensive Exam Prep

Conducting a duct leakage test is essential primarily because it helps assess energy losses within the heating, ventilation, and air conditioning (HVAC) system and enhances overall system efficiency by detecting air leaks. Ductwork is responsible for distributing conditioned air throughout a building, and leaks in the ducts can lead to significant energy waste.

When ducts are leaking, conditioned air escapes into unconditioned spaces, meaning that the system has to work harder to maintain the desired temperature, resulting in increased energy bills and diminished comfort levels. By identifying and addressing these leaks, homeowners or building operators can improve energy efficiency, lower operational costs, and create a more comfortable indoor climate.

While the other options touch on various aspects of HVAC systems, they do not specifically address the core purpose of a duct leakage test, which is primarily focused on identifying inefficiencies caused by air leaks in the ductwork.
