It's no better time to download the HVAC ResLoad-J app allowing you to perform field-based ACCA-approved HVAC load calcs. This Manual J8 residential load calculation app allows engineers, contractors, and technicians to perform field-based cooling and heating load calculations on residential and small commercial buildings. Users are then able to email PDF reports to customers and local building officials. Reports produced by this app will be accepted by all municipalities/states (including Florida and Massachusetts which recently passed laws requiring contractors to submit load calcs from ACCA-Approved software.)
