What is live in Path D right now?

The pre-start and first start-up module, its graded RTU First Start-up Sequence lab, and the free start-up and commissioning checklist. Remaining modules release progressively.

Is the start-up lab free?

Yes. The RTU First Start-up Sequence lab is public and playable without an account.

Do I need Path C first?

It helps but is not required. Path C teaches diagnosis on existing rooftop equipment; Path D teaches getting new equipment running correctly.

Does this replace manufacturer start-up documentation?

No. Always follow the equipment manufacturer's start-up procedure. This path teaches the judgment and sequence behind it.

Path D

Installation, Start-up & Commissioning

Install it, start it correctly, and prove it with numbers. This path takes technicians from service-only work to equipment that is set up right the first time and handed over with a record that stands up months later.

High-value diagnostic training we stand behind — work the graded labs, then book the credential that applies where you work: EPA 608, NATE, Red Seal, ARCtick, F-Gas, CDACC, SAQCC Gas or ESSCI.

Free exam practice for this path

Commissioning work assumes solid fundamentals and refrigerant-handling knowledge. Work the free practice questions with explained answers alongside these modules — exam preparation only, no official credential is issued here.

Who this is for

Service technicians asked to run or verify their own installations
Install crews who want the start-up and commissioning half done properly
Owners who keep paying for callbacks that trace back to start-up shortcuts
Commissioning agents and supervisors verifying other people's work

Install → start up → verify

Run a pre-start checklist and know when to refuse to energise the unit
Execute a first start-up sequence in the correct order, stage by stage
Prove fan rotation, airflow and static pressure before touching refrigerant
Braze, pressure-test, evacuate and charge to a documented standard
Recognise the start-up faults that become callbacks weeks later
Leave a commissioning record the customer and the next technician can use

Start with the free checklist

The pre-start and first start-up checklist is public and free. Work through it, then prove the sequence under grading in the RTU First Start-up Sequence lab — including a wrong fan rotation and the measured verification before handover.

Certificate

HVAC Installation & Commissioning Certificate (Academy)

On completion of the required modules and labs you receive a path-based, permanently verifiable EcoPowerHub Academy certificate confirming installation and commissioning competency. It supplements, and never replaces, any official credential required in your region.

Path-based, permanently verifiable diagnostic-competency certificate — our record of the graded work you did here, alongside the official credential you book in your region.

Certificate eligibility

To be eligible for the HVAC Installation & Commissioning Certificate (Academy) you must complete the required modules and pass the required start-up and commissioning labs as they release.

Pass the RTU first start-up sequence lab
Complete the pre-start checklist module
Pass the brazing, pressure-test and evacuation decision lab (releasing next)
Pass the commissioning verification lab (in development)

A lab is passed when the correct sequence is followed, the verification readings are taken and recorded, and no safety violation was recorded.

This certificate confirms demonstrated installation and commissioning competency inside EcoPowerHub Academy. It is not a statutory, electrical, gas or refrigerant-handling credential and does not replace any credential required in your region.

Regional exam-prep notes

United States: Book EPA Section 608 (Type II / Universal) at an EPA-approved proctor — NATE, ESCO or HVAC Excellence — then NATE for the specialty.
South Africa: Book the SAQCC Gas safe-handling authorisation for in-scope gas work; SAQCC Gas issues it.
Kenya / East Africa: Book the NITA / EPRA-adjacent assessment that matches your scope of work with the relevant body.
India: Book the ESSCI RAC Service Technician (NSQF) assessment; ESSCI and the Ozone Cell run the official credentials.

Always verify current requirements with the authority in your jurisdiction.
