Frequently Asked Questions (FAQs)
What is The Difference Between This and The HVAC Course?
This course is a “specialized” version focusing heavily on Air Conditioners and Refrigerators. The HVAC course is broader and includes central heating and industrial ducting. This course is perfect if you want to start a shop or work as a field technician.
Do I Get to Practice on Real ACs?
Yes. We have a dedicated lab with Split ACs, Window ACs, and Inverter units where you will perform actual gas charging and installations.
Can I work for Companies Like Haier, Dawlance, or Gree?
Many of our graduates are successfully employed as “Authorized Service Technicians” for these major brands because of our focus on modern technology.
