HVAC School - For Techs, By Techs


Sep 9, 2021

In today’s podcast, Ed Janowiak comes onto the podcast to talk about the ACCA manuals. Ed started off in the field and has recently become the new Manager of Design Education at ACCA. You can follow him on Snapchat (skinnyed).

 

ACCA (Air Conditioning Contractors of America) is responsible for publishing and setting the standards in all of the books we use for residential and light commercial HVAC work. (Residential work typically encompasses Manuals J, S, D, and T).

 

The manuals can be very math-heavy. Many software programs have come on the scene to help automate the math to some degree, but the manuals will still remain relevant for years to come. The ACCA manuals offer guidelines for predictable results, and much of a technician’s success will come down to how well they understand the order of operations.

 

In our trade, we have developed rules of thumb that help us with sizing and load calculations. However, those won’t work all the time, and the predictability element is lost. The ACCA manuals exist so that you can complete your calculations, sizing, and equipment selections with some degree of rhyme and reason. 

 

ACCA updates the manuals on 5-year cycles; the manuals require periodic updates to keep up with new climate trends and new equipment as it hits the market. The information in the manuals is not 100% accurate and is variable, but that is just a product of our ever-evolving industry and world. 

 

Ed and Bryan also discuss:

 

  • Leadership responsibilities in ACCA
  • Why HVAC business owners should be aware of the ACCA manuals
  • 400 CFM per ton
  • Mediocre designs
  • Moisture problems and design conditions
  • Basements, elevation, and insulation
  • Constructive criticism
  • ACCA training
