NCI Residential System Performance Specialist
Complete study program for the NCI Residential System Performance Specialist. Progress through 8 structured modules covering all exam topics.
- Measure total external static pressure (TESP) on residential furnaces, air handlers, and heat pumps
- Compare measured TESP to the manufacturer's rated maximum external static pressure and the 0.5 inches w.c. NCI benchmark
- Break down the static pressure budget to identify which component (filter, coil, supply ducts, return ducts) is creating excess resistance
- Explain the relationship between static pressure and airflow and how excessive TESP reduces system capacity
- Measure total system airflow using the TrueFlow plate and digital manometer
- Calculate airflow using the temperature rise method with known BTU input and measured delta-T
- Measure individual register airflow using a powered flow hood and compare to room-by-room design requirements
- Apply the 400 CFM per ton standard and identify systems operating below the 350 CFM per ton minimum
