Energy Systems Technology - HVACR

Industry Description
Technicians apply technical training in electrical, electronics, environmental, and mechanical to operate, maintain and service these types of HVACR systems:

Heating and air conditioning (HAC) equipment are climate control systems installed in buildings. In addition to providing thermal comfort they are meant to provide acceptable indoor air quality and the ability to regulate and maintain the systems. An HAC system typically consists of central forced air heating, and air conditioning equipment. Central heating equipment generally consists of a type of furnace or heat pump used to heat water, steam or air in a central location, and them distributes the heat through piping or ductwork.

Ventilation (V) systems, a forced or displacement ventilation system can also be used to control humidity or odors through heat recovery ventilators (using heat exchangers to bring the fresh air temperature to room temperature) or displacement ventilation systems (introducing air into a room at low velocities). Air conditioning equipment provides heating as well as cooling and humidity control to a building with increased energy efficiencies.

Refrigeration (R) is the process of controlling temperature and humidity to process or preserve products such as food, pharmaceuticals, semiconductors, artifacts, and medical supplies.

Entrance Requirements
Students contemplating entering the Energy - HVACR training program should complete an online application, complete financial aid forms, and take a placement test offered by Walla Walla Community College, and then meet with a program advisor in the HVACR training area. A high school diploma or GED® is recommended for entry into this program and is required if students are pursuing an AAAS degree.

WWCC Energy - HVACR is an approved electrical training program through the State of Washington (WAC 296-46B-971) and to comply with Washington Law students entering the program that will be working in Washington State are required to obtain Washington State LNI Electrical trainee card within the first two weeks of the quarter enrollment (this may be waived if out of state, and will be covered during program orientation). Students completing an AAAS degree will receive 1419 electrical hours on the 06A.

Students may enter the program fall, winter or spring quarter, however, due to course sequencing it is recommended the students begin in the fall quarter.

NOTE: It is recommended that the student contact the lead instructor and discuss program interest and to determine appropriate program placement; paying a priority list fee will hold placement in the program, and this fee will be applied to your tuition.
