Inspecting HVAC Energy Efficiency for Inspectors Course

Start the Course
Welcome to InterNACHI's free, online Inspecting HVAC Energy Efficiency Course.
The typical home buyer purchases a home without first fully understanding what it costs to operate it. Most homeowners do not understand where energy (and, therefore, money) is being wasted in their home. For the average American homeowner, heating and cooling accounts for over 55% of annual energy usage.
There are many approaches to reducing the heating and cooling costs of the utility bill, including:
  • properly maintaining the existing HVAC system;
  • improving the energy efficiency of a system in need of repair; and
  • picking the right heating and cooling equipment when replacement is needed.
The goal of this course is to teach the student what it takes to operate a house, including the energy costs of the HVAC system.
Upon successful completion of this training course, the individual be able to:
  • identify and describe energy-efficient heating, ventilation, and cooling (HVAC) equipment;
  • understand and provide informative options to help homeowners cut their energy use, reduce their carbon footprint, and increase their homes’ comfort, health, and safety; and 
  • help homeowners make informed decisions about purchasing new HVAC equipment or improving existing equipment for more efficient operation.

Course includes:
  • 52,064 words;
  • 5 minutes of video;
  • student book;
  • inspection and writing assignment;
  • research and writing assignment; 
  • 29 quiz questions within 4 quizzes;
  • 60-question final exam (drawn from a larger pool);
  • instant grading; and
  • downloadable, printable Certificate of Completion.

InterNACHI... #1 in inspection education.
Some features which make InterNACHI's courses superior to existing continuing education options:
  • The course is free for all InterNACHI members.
  • The course is written in pure XHTML code for quick loading.  The course loads fine on old computers and loads fast, even with dial-up.
  • The course is designed using a hierarchal menu coupled with a sequential page navigation.  This provides the student with the option to easily repeat areas of weakness.
  • The course permits the student to start, stop and restart any part of the course as often as desired.
  • There are a variety of images within the course, including diagrams, illustrations and photos. 
  • The illustrations can be enlarged for clearer viewing by clicking on them.
  • The text is integrated into InterNACHI's Inspector Glossary.  Rolling over blue-colored terms provides their definition.
  • The final exam uses multiple-choice questions that reference the images. 
  • The course's quizzes and final exam have numerous advantages over traditional exam systems:
    1. The course, quizzes and final exam incorporate built-in intelligence which identifies and strengthens each student's unique subject weaknesses.
    2. Not only is each question weighted with regard to score, but each answer is weighted, as well as the correctness of each answer being weighted.
      1. Answers to easy questions are weighted such that the student is penalized, in terms of score, for answering incorrectly, but rewarded modestly for answering correctly.
      2. Answers to difficult questions are weighted such that the student is rewarded, in terms of score, for answering correctly, but not penalized for answering incorrectly.
      3. Answers to questions regarding basic safety, or questions every inspector should know the answer to, are weighted such that the student is severely penalized, in terms of score, for answering incorrectly.
  • Upon passing the final exam, the student can print out a Certificate of Completion, which is auto-generated in the student-inspector's name.
The student-member's information is recorded on InterNACHI's servers for membership compliance verification, and automatically logs completion into InterNACHI's online Continuing Education log.
