Standards ecosystem

Built for codes and quality—not just the calendar

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.

Technical manuals — size and design

  • Manual J — load calculation

    How much heating and cooling the home actually needs from building characteristics—not square-footage rules of thumb.

  • Manual S — equipment selection

    Match equipment to sensible and latent loads using OEM performance data—reducing short cycling and comfort callbacks.

  • Manual D — duct design

    Size supply and return ducts for airflow and comfort; poor duct design hits IAQ and customer satisfaction.

  • Manual T — air distribution

    Size registers and grilles so conditioned air reaches each room as intended.

Quality standards — install and prove it

  • ACCA 5 QI — Quality Installation

    Minimum requirements for design, installation, testing, and commissioning—plus how you measure, verify, and document them.

  • QA accreditation

    Residential Service & Installation (RSI) and New Homes tracks—company-level process compliance contractors can pursue.

  • QI certificates (VEO / VSP)

    Verified Equipment Operation and Verified System Performance—including ductwork—often tied to third-party verification workflows.

Where HeyJack maps in

  • Manual JAI-assisted load planning—home details in, documented tonnage / load assumptions out (replacing eyeball sizing).
  • Manual SEstimates that reference load outputs and equipment tables so replacement sizing follows the math.
  • Manual D / TJob checklists for duct measurements, static pressure, and grille notes—stored on the job record.
  • ACCA 5 QICommissioning-style completion steps and a defensible job file: testing, sign-off, and documentation trail.
  • QA programsOngoing documentation that supports accreditation audits without rebuilding binders from scratch.
  • VEO / VSPFuture: pair HeyJack job data with field verification apps (e.g. measureQuick-class workflows) for airflow and pressures.
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.
Positioning for contractors who want fewer callbacks and a customer story: documented, standards-aware work.

Everything You Need to Run Your Business

From estimate to invoice—field checklists, owner KPIs, and AI where it saves time—so you can focus on the work, not the paperwork.

Manual J / S / D–aware ops

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.

ACCA 5 QI–style job completion

Checklists for install, distribution, and commissioning prompts—Manual D duct notes, static pressure, documentation—so the truck leaves with a defensible record.

KPIs + accreditation trail

Owner metrics plus the documentation path QA-style programs expect—less binder-chasing when you need to prove process.
