Testing and balancing can be interesting and challenging. You may encounter:
• Improper or too few balancing dampers in air systems
• Water systems without flow meters or balancing valves
• Duct and pipe systems without enough straight duct and pipe to obtain accurate flow quantity measurements
• Ducts with large aspect ratios
• Leaks in air ducts, water pipes, dampers, air valves and water valves
• Uninsulated ducts and pipes which increase the loss of thermal energy
• Ducts and pipes installed incorrectly, e. g., supplies connected to returns, etc.
• Failure of the system to supply the proper air and water temperatures to terminals and the controlled space
