APTRON HVAC Training Courses and Classes Overview

HVAC (heating, ventilation and air conditioning) courses can be taken through diploma, certificate, associates, or bachelor’s degree programs. Find out what fundamental information you can learn before becoming a HVAC technician.

The curriculum in different levels of HVAC programs is similar, but the programs vary in length, with the diploma and certificate programs lasting approximately 6 months or less. It normally takes 6 months to complete an associate’s training program. While not commonly available, there are some 4-months HVAC certification programs in Delhi. The advanced training program can find HVAC content in mechanical or architectural engineering programs. Listed below are some of the topics you can expect to see in your courses:

Power and resistance

Electrical heating


Water volume

Green technology

Cost efficiency

Basic Electricity for HVAC Course

Introductory electricity courses familiarize students with principles of electricity used in the HVAC (heating, ventilation and air conditioning) industry. Topics common to basic electricity courses include component theory and operation, proper use of test equipment and electrical circuits. Lectures also cover the use of wiring diagrams to evaluate low- and high-voltage currents.

Current is… The way water flows through a copper pipe or hose, electric current flows through a copper wire, measured in amps, or amperage.

Voltage is… The push or force of the water is equal to the force or push of the actual electricity, measured in volts, or voltage.

Resistance is… defined as a material’s ability to resist the flow of current. Compare it to a water valve. The more you open a water value, the less resistance you apply to the water allowing a greater volume of water to flow.

Arcing — The result of high voltage is obvious when watching a Tesla Coil. Air, like your body offers resistance. If the voltage is high enough, and a source to ground is too close, electricity will jump from the source to the ground. The higher the voltage, the greater potential for arcing.

Phase — Homes in general offer only Single Phase power. Basically, only one electrical power source is feeding a home. Three Phase power is three separate power sources, all feeding one piece of equipment at the same time. Three phase power is often used in large manufacturing equipment and commercial HVAC units.

Air Conditioning Control Principles Course

This basic HVAC Training course in Delhi teaches students about temperature, pressure and the electrical controls used in air conditioning equipment. Lessons cover motor starting devices, troubleshooting safety controls and operating relays. Instructors also provide an overview of Ohm’s law, which examines the relationship among current, voltage, power and resistance, as it relates to air conditioning circuits and controls. Students practice maintaining residential and business air conditioning systems.

Gas and Electric Heating Course

These HVAC classes cover the principles and procedures used to service heating systems. Students gain experience installing, operating, maintaining and repairing gas and electrical heating systems. This includes both older systems and modern systems that use green technology.

HVAC Systems Design Course

In this HVAC class, students examine direct digital control (DDC) systems for heating, ventilation and air conditioning. They come to understand how systems maintain water volume and various temperatures, in addition to the proper procedures for making sure a system is working correctly. These courses also might focus on the design process for DDC systems.

Energy Management and Green Building Course

Students in this course develop a working knowledge of the engineering behind HVAC systems. They learn to investigate problems, gather samples and conduct tests to identify possible pollutants, which might include lead, chemicals or mold. They also explore cost-efficient ways to replace old systems and manage new ones.
