Advances in technology, new construction of homes and businesses, renovation of older homes and buildings and an ever increasing population create a very favorable climate for workers in the Heating, Ventalating, and Air Conditioning (HVAC) industry.  HVAC technicians are involved with the installation, maintenance and possibly design of heating, ventilation and air conditioning units or systems.  Some workers specialize in one of these fields, while others may do it all.

In general, HVAC technicians do the following things:

• Installation of HVAC units, including electronic and mechanical components
• Installation of HVAC ductwork including flexible tubing and sheet metal construction
• Troubleshoot and repair HVAC units including electronic and mechanical components
• Install or repair fuel and water supply lines
• Conserve, install and recycle CFC and HCFC (Chlorflourocarbon family) refrigerants
• Install or repair electrical connections to HVAC components
• Install or repair HVAC system automation components for businesses or "smart homes".

Working conditions for HVAC technicians are not ideal.  Work may take place in cramped, dirty/dusty, cold, or hot conditions.  Safety must be considered in dealing with electricity, flammable fuel lines and CFC chemicals.  HVAC technicians may have to fish wires or pipes through existing constructions.  Respiratory precautions may also be taken because of exposure to dust, refrigeration chemicals and possibly asbestos in older buildings.

HVAC technicians may work in a variety of business types including HVAC manufacturers, privately owned contractors or institutional buildings like shopping malls, apartment buildings or complexes and schools.

A career as a HVAC technician is a great choice for someone with mechanical aptitude who wants to earn a great income in a profession that has strong growth possibilities.
