The goal of this course is to teach real estate professionals how to help their clients save money by reducing home energy consumption.


Upon successful completion of this training course, the individual be able to:

  • understand the value home energy inspections for current and prospective homeowners;
  • 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.

This course will also help:
  • protect the general public and registrants in real estate transactions;
  • enable registrants to better serve the objectives of the consumer in real estate transactions; and
  • develop and enhance the competence and professionalism of registrants in a changing marketplace. 

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 homes. 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 course includes:

  • 4 InterNACHI® CE credit hours;
  • 27,400 words in the course;
  • 24,000-word, downloadable course book;
  • one 3-minute video;
  • 30 questions within 4 quizzes;
  • a 40-question final exam (drawn from a larger pool);
  • instant grading;
  • a downloadable, printable Certificate of Completion; and 
  • accreditations and state approvals.
