Air Conditioning Service

Mon.- Thurs. 8:00 a.m.-4:30 p.m.,
Fri. 8:00 a.m.-11:00 a.m. (4.5 Days)

Course Benefits

This is a comprehensive, entry-level air conditioning service course. It concentrates on essential refrigeration knowledge that all HVAC technicians must eventually possess in order to perform competent HVAC service work. After attending, technicians should have acquired knowledge in tool usage, basic system theory, metering devices, system problem identification, superheat, subcooling, piping, and evacuation and recharging techniques. This course is 45-50 percent lab intensive. Packaged rooftop units, 2 to 5 tons, are used in the lab sessions. A separate course is available to help develop electrical troubleshooting skills.

Commercial Service 1

Mon.-Thurs. 8:00 a.m.-4:30 p.m.,
Fri. 8:00 a.m.-11:00 a.m. (4.5 Days)

Course Benefits

This course exposes the student to light commercial unit operation, set-up and troubleshooting, dual compressor units, refrigerant system troubleshooting, heating fundamentals, combustion analysis and unit airflow set-up and checkout. Hands-on training, using Trane light commercial 5 to 25 ton lab equipment, enhances the existing knowledge of technicians who already have appropriate fundamental A/C service skills. The course emphasizes a systematic approach to HVAC service troubleshooting.

Commercial Systems Service

Mon.-Thurs. 8:00 a.m.-4:30 p.m.,
Fri. 8:00 a.m.-11:00 a.m. (4.5 Days)

Course Benefits

This course exposes the student to light commercial unit operation, set-up and troubleshooting, utilizing two Commercial Self Contained (CSC) systems. Reviewing a simulated building plan, the students will learn the proper operation of the refrigeration system, configuration of airside vav boxes, set-up and checkout. Hands-on training, using Trane CSC, along with the Rover service tool will ensure the students have attained a good working knowledge of the system.

HVAC Electrical Troubleshooting

Mon.-Thurs. 8-4:30
Fri. 8-11:00 a.m. (4.5 Days)

Course Benefits

This course is intended to improve a technician's ability and confidence when electrically troubleshooting commercial HVAC equipment. The course will broaden the technicians' capabilities to troubleshoot controls and other electrical circuits by teaching an understanding of practical electrical theory as applied to the products and components found in HVAC. The information and skills learned should greatly decrease service diagnosis time and take the guesswork out of isolating problems found in single-, and three-phase air conditioning and heating products. This course makes extensive use of hands-on methods.

Water-Air Systems Service

Mon.-Thurs. 8:00 a.m.-4:30 p.m.,
Fri. 8:00 a.m.-11:00 a.m. (4.5 Days)

Course Benefits

This week-long course is intended to provide attendees with a "systems" approach to maintaining and diagnosing problems involving air distribution and water piping systems. It will show technicians and supervisors how Trane utilizes water flows to obtain the most efficient chiller operation possible. The course will also discuss water system conditions that can be detrimental to efficient operation and possibly damaging to system components. It instructs students in appropriate airside systems maintenance and troubleshooting procedures. Students will take flow measurements in a laboratory setting, using recommended tools and techniques and learn how to obtain peak cooling tower performance. Chilled water optimization with multiple chillers will also be discussed, along with chiller control strategies for variable water temperature / flows using Trane Adaptive Control™ technology.
