New System Installation Workflow: the full procedure

Standardizes the end-to-end installation of a new heating or cooling system from design verification through commissioning handoff.

What you need

The procedure, step by step

  1. Verify the design package — Confirm the job has a completed Manual J load, Manual S equipment selection, and Manual D duct design on file before the crew rolls; the calcs themselves are owned by the qualified designer.
  2. Confirm equipment and permits — Match delivered equipment to the submittals and confirm permits are pulled where required by the applicable codes.
  3. Protect and stage — Lay floor protection, stage tools and equipment, and review the day’s sequence and safety plan with the crew.
  4. Remove old equipment — Decommission and remove the existing system; refrigerant recovery is performed only by a certified technician under EPA Section 608.
  5. Set and connect new equipment — Set the new unit and make duct, line-set, condensate, electrical, and gas connections per manufacturer instructions and code, by qualified personnel.
  6. Commission the system — Follow the manufacturer’s commissioning and startup procedure to verify airflow, charge, and operation; regulated steps follow the certified path and safety plan.
  7. Document the install — Photograph the finished install, record model/serial numbers, and complete the commissioning checklist for the warranty file.
  8. Hand off to the customer — Register the manufacturer warranty, walk the customer through operation and the thermostat, and leave manuals and the maintenance schedule.

Quality check before you finish

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a HVAC business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan. Open the tool above to print it, toggle ink-saver, or (with a free ToolFluency Business account) edit it to match your own workflow.

Free printable HVAC installation SOP: verify Manual J/S/D design, match equipment and permits, commission, and document a quality install.

How to use

  1. Read the full procedure top to bottom before the work — the SOP runs in order and each step builds on the last.
  2. Toggle Ink-saver (black & white) for a cheaper mono print for the binder; leave it off for the full-color version.
  3. Click Print SOP to print or save as PDF. Print one per crew, laminate it for the binder, or attach it to the job in your scheduling system.
  4. Train new hires on it and have staff sign off. Found something out of date? Use the feedback link — flagged SOPs are re-researched against the source list.

Frequently asked questions

Why must Manual J/S/D be on file before installing?
ACCA’s Manual J (load), Manual S (equipment selection), and Manual D (duct design) are the recognized design basis, and Energy Star’s Quality Installation program treats them as prerequisites for a right-sized, efficient system. This SOP ensures the workflow always includes that package; the calculations are performed by a qualified designer.
Who handles refrigerant during a system swap?
Refrigerant recovery, evacuation, and charging are performed only by a certified technician under EPA Section 608 rules and the applicable codes. The SOP sequences when those steps occur but defers the regulated work itself to the certified path and the business safety plan.
