HVAC & Refrigeration Mechanics and Installers

HVAC Schools

Heating, air conditioning and refrigeration mechanics and installers - also known as HVAC technicians - ensure the air quality in a building is high and proper temperatures are met. That can mean a variety of things based on the size and purpose of the facility. From the freezer section of a grocery store to hot yoga and dance studios, HVAC technicians are charged with maintaining air ducts, water supply lines, fuel systems and other components to ensure everything works reliably and efficiently.

With online HVAC technician schooling, you may learn what it takes to pursue a career installing, maintaining and improving HVAC systems to provide the most conducive climate-controlled environment. Furthermore, as some states begin requiring licenses and certifications for HVAC professionals, you can study what new guidelines must be met for employment at your own pace. Online schooling is often more convenient for students, as much of the work can be done remotely and at your leisure.
