  • understand the value of Home Energy Reports™ 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.

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.
And, in keeping with InterNACHI's commitment to Continuing Education, this online training course is open and free to all real estate professionals, and can be taken again and again, without limit.
The course requires the student to sign a written statement under penalty of perjury that the participant enrolled in the course is the personal completing the course, and ensures the course can not be completed in less time tan the approved credit hours by controlling the participant's navigation through the course content.
