HVAC workers design, sell, install, and repair heating, ventilation, and air conditioning systems in various structures. They can pursue careers as engineers, manufacturers, technicians, or salespeople, requiring higher education and formal training. Engineers design efficient, economical, and environmentally friendly systems using computer-aided design software. Assemblers and fabricators manufacture component parts, while salespeople offer advice and consultation to customers. Technicians install, maintain, and repair systems, requiring vocational training and licensing exams.
Many skilled people are involved in the design, sale, installation and repair of heating, ventilation and air conditioning (HVAC) units. HVAC workers are essential in providing comfortable, temperature-controlled environments in private homes, as well as offices, schools, hospitals, warehouses, and other large structures where people live and work. People interested in HVAC employment can pursue careers as engineers, manufacturers, technicians or salespeople. Depending on the nature of HVAC employment, individuals are generally required to pursue some form of higher education and complete formal training programs.
HVAC plant research and development departments hire qualified engineers to design, test and build new units. Engineers use their advanced knowledge of mathematics and physics to design systems that are efficient, economical, environmentally friendly and simple to use and maintain. Typically, they employ computer-aided design software and various other programs to help them design designs and perform what-if tests on units. Many engineers work with a team of assemblers to build and test prototypes. To obtain HVAC employment as an engineer, an individual is generally required to earn a bachelor’s degree or higher in mechanical engineering and complete formal on-the-job training from established professionals.
Assemblers and fabricators manufacture the component parts of HVAC systems. Workers use a variety of hand, power, and computer-controlled tools to cut, bend, weld, and shape parts. Skilled workers often manipulate robotic equipment to assemble final products. Some systems, however, ship to retail stores or end users only partially assembled; parts arrive in boxes with special instructions on how to build units. Fitters and fabricators can gain employment in HVAC by obtaining certification from accredited vocational schools or participating in formal apprenticeships.
When a home or business owner wants to purchase a new HVAC system, he or she usually consults with knowledgeable salespeople at distribution plants, HVAC stores, or specialty hardware stores. Salespeople and women receive detailed instruction from trainers on the different types of HVAC systems and the best options for various installations. Some salespeople and consultants visit customers’ homes or businesses to help them determine what type of system to buy and how much it will cost.
Many skilled professionals find employment in HVAC as technicians, responsible for installing, maintaining, and repairing systems. Professionals follow blueprints and instructions to ensure new systems are installed properly and safely. They usually have detailed knowledge of how to troubleshoot faulty motors, gauges and pressurized pumps. HVAC technicians are often required to complete vocational training and extended apprenticeships to master the difficult trade. Additionally, many states and countries require new technicians to pass extensive licensing exams before working independently.
