HVAC Journeyman 2025 – 400 Free Practice Questions to Pass the Exam

After installing a cooling coil in the duct system, ensuring compliance with local building codes is essential. Local codes often dictate standards for safety, efficiency, and performance. These codes can include specifications about the installation process, material requirements, and performance metrics that must be achieved. Adhering to these guidelines helps ensure that the cooling system functions correctly and safely, protecting both the occupants and the integrity of the building.

While the other conditions mentioned—such as air pressure parameters, operational furnaces for testing, and the order of air passage through the cooling coil—are important for the overall functionality and efficiency of the HVAC system, they are not as critical as compliance with legal and safety standards established by local building regulations. Ensuring that the installation meets these codes reduces liability issues and supports the long-term reliability of the HVAC system.
