System Performance

System Performance, Maximizing Energy Efficiency

Program Description

Heating, Ventilation, Air Conditioning (HVAC) equipment is only as good as the installation. Studies show that the majority of residential HVACR equipment is not installed to manufacturer specifications, costing the consumer money. This program is designed to provide information required to properly setup an air conditioning or heating system to achieve the equipment efficiency ratings.

The instructional materials are separated into four topics to fit the needs of the user.


This program can be incorporated into any HVACR educational curriculum that teaches the principles of air conditioning, as part of your current program or can be used as a stand-alone course.

Wholesalers, manufacturers, and continuing education providers can use this program as a continuing education course to reinforce concepts in a 4 to 8-hour training program.

A Comprehensive Resource

System Performance issues are spread out in most HVACR text books, this textbook puts it all together in one location. This program is a comprehensive resource providing students and practicing technicians the techniques and procedures required to maximize the energy efficiency of HVACR systems and reduce call backs.

Areas of Competency

This program has been cross-walked or aligned to the HVAC Excellence Competency and Task List, to assist instructors in providing their students with the HVACR knowledge and skills necessary for employment in the HVACR industry.

Program Topics

  • Airflow
  • Critical charging procedures
  • Psychrometrics
  • Combustion analysis

System Performance, Maximizing Energy Efficiency

© 2014 ESCO 176 Pages

The System Performance training manual is broken into four sections. Each section covers the techniques and procedures required for a technician to maximize the energy efficiency of HVAC systems.

  1. Airflow
    Covers the properties of air, airflow measuring tools, CFM calculations/requirements, blower performance, and sensible heat ratios.
  2. Critical Charging
    Reviews the three charging methods: by weight, system superheat, and condenser subcooling. It gives examples of calculating the total charge based on line sizes and provides an easy method to verify that a system is operating at its rated capacity.
  3. Psychrometrics
    Covers parts of the psychrometric chart and calculating the thermodynamic properties of air. Also, this section demonstrates using wet and dry bulb temperatures to plot the conditions of air being heated or cooled which enables the technician to view a system’s effect on the sensible and latent heat load of a building.
  4. Combustion Analysis
    This section reviews the basic combustion process and the factors that affect heating efficiency. Proper methods for setting furnace airflow, adjustment and testing fuel pressure, and flue gas venting are covered.

Instructor Resource Materials

PowerPoint presentation: The instructor resource materials include a 201-slide PowerPoint presentation that correlates directly with the training manual. Each slide within the presentation contains speaker notes that are designed to aid the instructor through the presentation and provide additional talking points.

Instructor Guide: Is an instructional supplement with course objectives and estimated delivery times to keep the program on track. Answers to student worksheets are also included. Instructor resource materials are available through digital download or CD.


A four-part System Performance Certification covering refrigerant charging, psychrometrics, combustion efficiency, and airflow tests the knowledge a technician has in the processes and procedures required to ensure HVAC systems are performing at maximum efficiency. Each of the four sections on the exam contain 25 questions.

Proctors can login to review candidate test results and access detailed statistical reports. These reports help instructors pinpoint strengths and weaknesses in their instruction. Additionally, these reports aid the program in preparing documentation for Perkins compliance.

Training Package

To accommodate the varying needs of each HVACR training program, this modular training package is available as a complete training solution (training manual, instructor resources and certification), or instructors can purchase the items separately.
