Written for Indian RAC service technicians and service-company trainers: graded labs so you walk into an ITI/NCVT or Skill India assessment prepared — and stop guess-and-charge on Indian plant.
Interactive decision labs
·Built by working technicians
·Path-based verifiable certificate
·Know which exam to book
·Worldwide online
We train and prepare technicians; we are not NCVT, an ITI, Skill India, or ISHRAE and we do not issue NTC, QP, or ISHRAE certificates.
Exam preparation
Preparing for the India exams?
Prepares the diagnostic judgment expected before ITI / NCVT (CTS) Refrigeration and Air Conditioning Technician assessment and Skill India Field Technician – Air Conditioner assessments. We do not issue the National Trade Certificate, Skill India QP certificates, or ISHRAE credentials.
Same labs, tighter time, fewer hints — score against this region. Practising RAC technicians, service supervisors and trainers on 230 V single-phase and 400/415 V three-phase 50 Hz plant across residential, commercial refrigeration and rooftop work.
After the labs, you know which exam to book. You sit Core / Type / T2 / PV Associate and the equivalents with the examining body, and that body issues the credential. Prepare for ITI/NCVT NTC and Skill India AC technician assessment on 230 V and 400/415 V, 50 Hz.
Academy scores are training only. We do not issue the credential — NCVT/DGT, Skill India and ISHRAE issue their own credentials. Academy completion is not authorisation to work.
Supply, frequency, and conversions
Single-phase
230 V a.c. nominal
Three-phase
400 V / 415 V — read the nameplate: Indian field practice and older ITI texts say 415 V line-to-line, IEC-aligned equipment says 400 V. Both appear on real plant.
Frequency
50 Hz only
Code
National Electrical Code (NEC India) / IS wiring practice
Conductors
mm²
Units
°C, kPa/bar, kg. mm² conductors. 50 Hz only. Wiring and electrical licensing stay with state authorities — this track teaches diagnostic judgment, not licensed electrical work.
Temperature is measured in degrees Celsius. Gauges, ambients, and exam items on this track are °C, not Fahrenheit.
Conversion strip — reference only
Supply: V / HzTemperature: °C ↔ °FPressure: kPa ↔ bar ↔ psigMass: kg ↔ lbConductors: mm² ↔ AWG
Working decision values stay in this region's units — the strip is for translating charts and kit from elsewhere.
Marked wrong in labs
Treating the plant as US 120/240 V 60 Hz
Using Kenya 240/415 V as if it were the Indian default
Working in °F on a °C nameplate
Who the authority is here
NCVT / DGT
Craftsman Training Scheme for the Refrigeration and Air Conditioning Technician trade (NSQF Level 4), through ITIs and accredited CTS providers.
Issues: The National Trade Certificate (NTC) after the ITI / accredited CTS pathway.
Skill India / Sector Skill Councils
Short-cycle Qualification Pack roles such as Field Technician – Air Conditioner and related ESDM/electronics QPs.
Issues: Skill India QP certificates through affiliated training centres — a separate paper from the NTC.
ISHRAE
Society certifications such as ICP / ICEP, aimed mainly at HVAC design and professional engineering practice.
Issues: ISHRAE professional credentials — not a substitute for the mechanic NTC, and not something we award.
Ozone Cell, MoEFCC
Good servicing practice and refrigerant phase-out under the Montreal Protocol (HPMP / UNEP GSP language: recovery, leak control, flammable and low-GWP discipline).
Issues: Programme guidance and refrigerant controls — no certificate is issued by us or implied by completing these labs.
Good servicing practices (India)
The Ozone Cell (MoEFCC) promotes UNEP good servicing practices across the Indian RAC sector under the HCFC phase-out programme. These labs drill the same field habits.
•Recover refrigerant instead of venting, on every job.
•Find and fix leaks before topping up — never recharge a known leaker.
•Handle flammable and low-GWP refrigerants (R-32, hydrocarbons) with the ventilation and ignition discipline they demand.
•Service for efficiency: clean coils, correct charge and correct airflow cut energy use and repeat calls.
Good servicing practice is an optional international programme — completing these labs earns no Ozone Cell or UNEP certificate.
Prepare for ITI RAC / NCVT NTC (NSQF Level 4)
The Refrigeration and Air Conditioning Technician trade under the Craftsman Training Scheme runs about two years and ends in external assessment. The graded labs build the fault-finding, electrical isolation and charge/recovery judgment that assessment probes — before you sit it.
The National Trade Certificate is issued by NCVT/DGT through an ITI or accredited CTS provider, not EcoPowerHub Academy.
Skill India — Field Technician (AC)
Skill India Qualification Pack roles such as Field Technician – Air Conditioner are short-cycle certificates for AC install and field service work. The labs build the install and service judgment those assessments check — but this is a different paper from the NTC, not a shortcut to it.
We do not issue Skill India certificates — affiliated training centres do.
ISHRAE is a different path
ISHRAE certifications (ICP, ICEP and design levels) are society credentials for HVAC design and engineering professionals. They sit beside — not above — the mechanic trade certificate, and they are not what a field service technician is assessed on.
ISHRAE issues ISHRAE credentials; we do not. The mechanic NTC and ISHRAE ICP are not interchangeable.
Ordered diagnosis on 230/400-415 V 50 Hz
Indian plant runs 230 V single-phase and 400/415 V three-phase at 50 Hz. Older ITI texts and field practice say 415 V line-to-line; IEC-aligned nameplates say 400 V — read the nameplate, never assume. The diagnostic sequence does not change:
•Isolate electrically before touching the refrigeration circuit.
•Confirm airflow and charge before condemning a compressor.
•Recover refrigerant only when the repair actually requires it.
•Work in °C — never default to US °F / 120 V practice or to Kenya's 240/415 V on Indian plant.
This is skills preparation, not a credential — certificates come from NCVT/DGT, Skill India centres, or ISHRAE, never from us.
Preparation scope
What this training prepares you for
•Walk into ITI/NCVT (CTS) RAC Technician or Skill India Field Technician – AC assessment with tested diagnostic judgment.
•Fault-finding, electrical isolation and charge/recovery decisions on 230 V and 400/415 V, 50 Hz plant.
•Good servicing practice: recovery instead of venting, leak discipline and correct charging in high ambients.
•Service documentation a shop, warranty desk or assessor can act on.
What we do not issue
•We do not issue the National Trade Certificate — NCVT/DGT does, through an ITI or accredited CTS provider.
•We do not issue Skill India QP certificates or any ISHRAE credential.
•We do not run an ITI, and nothing here is ITI admission or a state electrical licence.
