ACCA publishes two big buckets: technical manuals (how to size and design) and quality standards (how to install, verify, and document). Energy codes, DOE, RESNET, BPI, and ENERGY STAR all point contractors at Manual J, S, and D—then ACCA 5 QI and related programs cover proof of quality in the field.
Industry studies suggest fewer than half of residential HVAC jobs use a full Manual J–style load calculation—yet codes and programs expect it.
How much heating and cooling the home actually needs from building characteristics—not square-footage rules of thumb.
Match equipment to sensible and latent loads using OEM performance data—reducing short cycling and comfort callbacks.
Size supply and return ducts for airflow and comfort; poor duct design hits IAQ and customer satisfaction.
Size registers and grilles so conditioned air reaches each room as intended.
Minimum requirements for design, installation, testing, and commissioning—plus how you measure, verify, and document them.
Residential Service & Installation (RSI) and New Homes tracks—company-level process compliance contractors can pursue.
Verified Equipment Operation and Verified System Performance—including ductwork—often tied to third-party verification workflows.
Most HVAC software just helps you schedule jobs. HeyJack helps you do the job right—with ACCA-aligned workflows, QI-style checklists, and AI that helps catch mistakes before they become callbacks.
From estimate to invoice—field checklists, owner KPIs, and AI where it saves time—so you can focus on the work, not the paperwork.
Roadmap: AI-assisted load inputs and equipment sizing tied to the job—not rule-of-thumb replacements. Today: structured job files that reference load and equipment decisions.
Checklists for install, distribution, and commissioning prompts—Manual D duct notes, static pressure, documentation—so the truck leaves with a defensible record.
Owner metrics plus the documentation path QA-style programs expect—less binder-chasing when you need to prove process.
