The U.S. Department of Labor's Bureau of Labor Statistics (BLS) forecasts excellent job prospects for heating, air-conditioning and refrigeration mechanics and installers, "particularly for those who have completed training from an accredited technical school." The rising number of workers nearing retirement age, the need for replacement for older systems with newer, energy-saving units, and other factors will create plenty of job opportunities. If fact, the BLS indicates contractors have reported problems finding enough workers to fill jobs.

And while entry salaries may be lower, average wages for experienced technicians can range up to approximately $18 an hour, according to 2008- 2009 edition of the BLS.s Occupational Outlook Handbook. Salaries and benefits vary by location and company.
