HVAC is an acronym that stands for heating, ventilating, and air conditioning. Professionals who work in the HVAC industry are known as HVAC mechanics or HVAC service technicians. They are responsible for installing, maintaining, and repairing the climate control system for a variety of structures. Temperature, humidity, and air quality must be closely regulated in order to meet health and safety standards, as well as create a comfortable environment for inhabitants and workers. Refrigeration, an essential part of food preservation, is also considered part of the HVAC industry. HVAC mechanics practice their trade in homes, offices, commercial centers, retail establishments, hospitals, factories, and other such buildings where climate control is needed.
Basic Duties and Responsibilities
HVAC mechanics install, operate, maintain, and repair the heating, ventilation, air conditioning, and refrigeration equipment for any structure. Many HVAC mechanics specialize in either installation or maintenance and repair, however most are trained to perform both. They may also specialize in a certain kind of HVAC equipment, such as solar panels. HVAC mechanics perform a variety of duties in a large number of capacities, ranging from setting up HVAC systems for schools to installing water-based heating systems in private residences. Their most basic duties are centered around the installation and maintenance of complex HVAC systems that are essential to a building’s operation.
HVAC systems are made up of a intricate array of mechanical and electrical components. A very large HVAC system may require several mechanics to install it, though HVAC mechanics generally work independently. During installation, the mechanic is responsible for properly installing water fuel and water supply lines, air ducts, vents, motors, compressors, evaporators, piping, and other components. HVAC mechanics can also be responsible for connecting electrical wiring and fixtures during the installation process. After installation, HVAC mechanics must make sure the system is operating properly by conducting a series of equipment tests. They are also responsible for disposing and recycling any chemical byproducts of the HVAC system.
HVAC systems require year-round maintenance and repair to run efficiently. HVAC mechanics perform tasks such as replacing fitters, ducts, and other components that collect dust and other waste during use. Mechanics generally perform maintenance on air conditioning systems in the winter and heating systems in the summer, when both are being disused. They are also responsible for diagnosing and repairing any problems that have arisen with the HVAC system.
HVAC mechanics use many special tools and equipment in order to install and maintain the system. Specific equipment includes hammers, wrenches, electric drills, pipe cutters, metal cutters, benders, thermometers, pressure gauges, manometers, acetylene torches, and volt meters. In order to perform their jobs efficiently, HVAC mechanics must be familiar with these tools, as well as the many electric and mechanical elements that make up an HVAC system.
Employment Outlook
Job opportunities for HVAC mechanics are projected to grow quickly over the next 10 years, due to the increasing complexity of HVAC systems. As HVAC systems grow more elaborate, the demand for HVAC mechanics to maintain and repair unforeseen problems will increase concurrently. Other key factors include an increased emphasis on air quality, energy management, and the environment. The development of newer, more environmentally-friendly HVAC systems will create new job opportunities for mechanics. The widespread use of refrigerated equipment also contributes to the demand for HVAC mechanics.
Job opportunities for HVAC mechanics who specialize in maintenance will remain steady, while those who work in installation will find that job opportunities depend most heavily on the level of construction in their area. The average salary for an HVAC mechanic is $40,000 per year, but can increase dramatically based on the amount and complexity of work they complete.
