College Catalog Fall 2016 - Spring 2017

Plumbing and Refrigeration - AOS

The Instructional Program

Plumbers install and repair the water, waste disposal, drainage, and gas systems in homes and commercial and industrial buildings. Plumbers also install plumbing fixtures - bathtubs, showers, sinks, and toilets - and appliances such as dishwashers and water heaters. Pipefitters install and repair both high-pressure and low-pressure pipe systems used in manufacturing. Plumbers must be able to follow building plans or blueprints and instructions from supervisors, lay out the job, and work efficiently with the materials and tools of their trade.

Refrigeration and air-conditioning systems consist of many mechanical, electrical, and electronic components, such as: motors, compressors, pumps, fans, ducts, pipes, thermostats, and switches. Technicians must be able to maintain, diagnose, and correct problems throughout the entire system. To do this, they adjust system controls to recommended settings and test the performance of the system using special tools and test equipment. Technicians often specialize in either installation or maintenance and repair. They also may specialize in doing heating work or air-conditioning or refrigeration work.

New students are accepted for the fall semester into the AOS degree program, and can then choose to begin their first year in the Plumbing, Heating, and Pipefitting advisement track or in the Refrigeration and Air-Conditioning advisement track.

Delhi 's skilled-trades students are sometimes given the opportunity to do a "hands-on" project.

SUNY Delhi uses Refrigeration Service Engineers Society (RSES) training manuals in all its refrigeration courses. Membership in the RSES Student Chapter is included in the textbook cost, and students take the RSES certification exam as a part of their program.

Minimum Requirements to be Considered for Admission


  • high school graduate with 70 high school GPA or 2500 GED test score
  • Algebra Regents recommended: 70

Transfer Student:

  • Transfer GPA: 2.0


SUNY Curriculum Code: 1159

SUNY General Education Requirements: Students who intend to receive AA, AS, or baccalaureate degrees must satisfy SUNY and campus General Education (GE) requirements to graduate. Students should be aware that GE requirements may vary by academic program. Consult with your academic advisor. For general information, see the "General Education" section of this catalog.

AAS and AOS degree students may not be required to fulfill General Education (GE) requirements; however, any student who may wish to transfer should complete as many GE courses as possible. Consult with your academic advisor.

Technical Standards: In addition to academic requirements, all applicants must also be able to meet the minimum Technical Standards for the program, with or without reasonable accommodation.

Academic Requirements:

Minimum Total Credit Hours = 64

Major Courses Required = 48 credit hours

The order in which courses will be taken depends on the advisement track chosen by the student on entry: the Plumbing/heating/pipefitting track or the Refrigeration/air-conditioning track. These advisement tracks permit students who successfully complete their first year, but who cannot attend college for a second year, to exit with a certificate that qualifies them to apply for a job in that field. Students must identify their advisement track before beginning their first semester.
