Online HVAC Classes

The best online courses for heating, ventilating, and air conditioning (HVAC) give students knowledge in a variety of topics, including programmable logic controllers, residential heating and air conditioning, refrigeration, systems installation, and electricity. Through these classes, students are able to hone their dexterity, reading comprehension, time management, troubleshooting, and judgment and decision making skills.

Online HVAC Classes

The study of HVAC involves learning how to repair and install heating, ventilation, and air conditioning systems that provide a climate-controlled environment in buildings. HVAC certificate programs typically last around six months, while associate degree programs may last two years, depending on the program and the student's ability to successfully complete each course. These programs will prepare students for licensure exams, if required by the state, as well as the U.S. Environmental Protection Agency's certification exam for proper refrigerant handling.

Knowledge Gained

Online heating, ventilation, and air conditioning classes provide students with knowledge in many areas, including the following:

Programmable Logic Controllers

Classes focused on programmable logic controllers introduce students to devices that control the regulation of an HVAC system without human action. Through these courses, students learn basic programming concepts, such as logic, number systems, and interfacing, as well as HVAC-specific topics like control instructions, timers, counters, and sensors.

Residential Heating and Air Conditioning

These courses focus on the different methods of regulating temperature in residential buildings, and installing and troubleshooting the various types of equipment found in homes. Duct installation, basic building construction, blueprint reading, and planned maintenance are some of the subjects covered these courses.

Refrigeration

Classes on refrigeration focus on the basic aspects of systems that provide cold climate control. These courses teach refrigeration principles, such as heat transfer theory, heat pumps, and government regulations on the conservation, recovery, and recycling of refrigerants.

Systems Installation

These classes teach students the entire process of installing systems in different types of buildings. Students learn how to connect systems to fuel and water supply lines, install electrical wiring and controls, test components, and provide routine maintenance.

Electricity

Students will learn the basic physics of electricity as they apply to HVAC systems. Students learn to apply Ohm's law, construct electrical circuits, select wires and fuses, troubleshoot electrical motors, and measure resistance, voltage, ohms, watts, and amps.

Skills Developed

Accredited online HVAC courses help students develop and refine skills in the following areas:

Dexterity

Courses help students refine their hand-eye coordination by teaching them how to operate the different hand tools used by technicians. Through courses that emphasize hands-on practice with machinery and circuitry, students gain improved dexterity that helps prevent injury and improve efficiency.

Reading Comprehension

Students learn to read blueprints and instructions, and then apply that information to installing and repairing systems. Students will learn how to make sense of various system manuals, allowing them to work quickly and efficiently.

Time Management

Students learn how to properly install and work on HVAC systems in a timely manner. As their skills improve, students begin to understand how long certain jobs typically take, allowing them to properly estimate the amount of time needed for a job and stay on track.

Troubleshooting

Students will learn how to identify problems in systems that lead to malfunctions. As they increase their familiarity with different systems, students' troubleshooting skills increase as well.

Judgment and Decision Making

Online programs give students the knowledge and skill needed to address difficult situations with unclear solutions. Students learn how to take what they have learned from basic guiding principles and real-life case studies to make informed decisions that minimize mistakes.
