A combination of classroom and shop learning experiences are used in the air conditioning and refrigeration program, which includes mechanical theory application, operation, and maintenance of basic and advanced air conditioning/refrigeration systems.

In addition, students learn about the different heating, gas, oil, electric, solar, and heat pump systems. Graduates find career opportunities as air conditioning/refrigeration technicians; sales, retail, and wholesale representatives; installers; maintenance and service; engineer helper; or operator. Full-time day and evening courses are available on the main campus.

About Program

Air conditioning and refrigeration systems are highly complex, operating with more than a single machine. They are sophisticated systems of interacting machines that produce cooling or heating. For example, air conditioning systems require fans, compressors, condensers, and evaporators to cool and dehumidify the air. Distribution of the treated air through the conditioned space is accomplished by using metal or fiberglass duct work or special piping. Technicians specializing in this field must be able to work with the complete system to be able to install and repair residential and commercial air conditioning and refrigeration equipment.

Classroom and shop learning experiences are concerned with the residential, commercial, and industrial air conditioning and refrigeration systems. The students also learn about the different heating systems including gas, oil, and electric furnaces.

Job Expectations

Technicians may work outside in all types of weather, in or on extremely hot and cold attics or roof tops, and in dark wet crawl spaces. In addition, technicians might work in awkward or cramped positions, and they are sometimes required to work in high places. Hazards include electrical shock, burns, muscle strains, and other injuries from handling heavy equipment. Appropriate safety equipment is necessary when handling refrigerants because contact can cause skin damage, frostbite, or blindness. When working in tight unventilated spaces, inhalation of refrigerant is a possible hazard.

Expected Earnings

Earnings as reported by the U.S. Department of Labor 2010-2011 Occupational Outlook Handbook are as follows: Median hourly wages of heating, air conditioning, and refrigeration mechanics and installers were $19.08. The middle 50% earned between $14.94 and $24.84 an hour.  The lowest 10% eared less than $12.19 and the top 10% earned more than $30.59.
