Online Refrigeration Course and Class Information

Online university courses in heating, ventilation, air-Conditioning and refrigeration (HVAC-R) are offered for students and working professionals. Read on to learn about an array of courses designed to prepare students for successful work in the HVAC-R field.

Overview of Online Refrigeration Classes

Online refrigeration courses are offered as part of online certificate or degree programs designed for prospective or current heating, ventilation, air conditioning and refrigeration installers and technicians. Programs cover skills necessary to successfully install, design, troubleshoot and service HVAC-R systems.
Successful HVAC-R certificate and degree program graduates are qualified to sit for exams administered through HVAC-R industry organizations such as the Air-Conditioning Refrigeration Institute (ARI) and the North American Technician Excellence (NATE).

Technical Course Requirements

Students need a computer and access to the Internet. Classes may require students to have access to Microsoft Office. An e-mail account is needed to communicate with teachers or fellow students.
When these classes utilize online learning platforms such as Blackboard, students submit assignments on a prearranged schedule and course timetables follow university academic calendars. Courses may also use a self-paced schedule; in this case, students submit assignments and take exams on their own timeline. For self-paced study, professors offer feedback when students turn in assignments.
Online HVAC-R classes often include video presentations, animations, images, website tours and inline quizzes. Exams may be taken online or under the supervision of a proctor. Textbooks are a common course feature and may be included in the program tuition.

List of Online HVAC-R Courses

Introductory HVAC-R Course

Courses in heating, ventilation, air conditioning and refrigeration fundamentals explore several aspects of HVAC-R technology, from basic HVAC-R terminology to safety in the workplace. Content includes heat transfer methods, applied physics for HVAC-R systems, industry HVAC-R measurements and handling hazardous materials.

HVAC-R Electrical Course

These classes explore basic electrical theory as it applies to CD and AC circuits. Ohm's law, circuit characteristics and schematic circuit symbols are examined as students look at control components in HVAC-R systems. Course topics also include control methods, transformers, motor theory and common motors, starting components, wiring and pressure residential thermostats.

HVAC-R Structures Course

Students analyze system functions, including airflow measurement methods, psychometrics, air properties and accurate comfort parameters. These courses emphasize common HVAC-R installation standards, heat transfer concepts, heat-loss issues and conditions of air.

HVAC-R Cooling System Course

Mechanical compression refrigeration cycles and essential operation components are covered to prepare HVAC-R technicians to size, install or design a cooling system. Students are introduced to basic refrigeration cycle physics, metering devices evaporation, cooling equipment and duct sizing.
