HVACR 122 Fundamentals of Load Calculations

This online course introduces you to residential load calculations. This is a method to determine the heating and cooling BTU/H loads of structures prior to installing HVACR systems to meet those loads. The required text is the Air Conditioning Contractors of America (ACCA) Manual J, 8th Abridged Edition (MJ8-AE). The manual provides thorough instructions for estimating heat loss and heat gain for residential structures and helps to simplify complicated procedures that are often used on a variety of home applications. This course will provide instruction for completing load calculations by hand, which is necessary prior to attempting any computerized load program. We will focus on following the concepts of MJ8-AE while simplifying the methodology emphasized in the manual even further. Students will utilize a “simple” residential structure and follow the steps to calculate both heat loss and heat gain for its location and outdoor design temperatures. This course also covers residential equipment selection focused on the heating and cooling equipment Btu/h loads of a structure. Recommended Prerequisites: you will want to have a strong working knowledge of basic HVACR fundamentals prior to enrollment into this advanced course. This course is NATE recognized for 18 hours of continuing education (CEHs) applicable to NATE re-certification, and BPI recognized for 9 continuing education units (CEUs). This course is presented in the following six modules:

  • Fundamentals of Load Calculations
  • Heat Loss of a Structure
  • Heat Gain of a Structure
  • Example Heat Loss and Heat Gain Calculation
  • Fundamentals of Equipment Selection
  • Regional Load Calculation Exercises

Each course purchase allows 60 days enrollment to complete. Must obtain a 75% or higher to obtain CEU recognition. Course provides you with a Subject Matter Expert (mentor) to assist with questions and all course materials for the duration of the course.
