Is This Career Right for You?

HVACR technicians often specialize in either installation or maintenance and repair, although they are trained to do both. They also may specialize in doing heating work or air conditioning or refrigeration work. Some specialize in one type of equipment—for example, hydronics (water-based heating systems), solar panels, or commercial refrigeration.

Technicians follow blueprints or other specifications to install oil, gas, electric, solid-fuel, and multiple-fuel heating systems and air-conditioning systems. After putting the equipment in place, they install fuel and water supply lines, air ducts and vents, pumps, and other components. They may connect electrical wiring and controls and check the unit for proper operation. After a furnace or air conditioning unit has been installed, technicians often perform routine maintenance and repair work to keep the systems operating efficiently.
