Alex Meaney is my trainer when I level up on HVAC design calculations, and he came to visit us and share some of his expertise.

Alex reveals what the J stands for and why you should never round up the tonnage from your Manual J software, and gives two rules for Manual S: 1. Never use AHRI data 2. Meet the latent load while not going too far over the sensible load (more in part 2) Check out Alex Meaney’s trainings: https://MeanHVAC.com
