NATE core and one specialty is the maximum number of tests allowed to be taken in a four hour time period.

This class will acquaint the student with basic electrical terms, components and circuits found in the HVAC industry. Schematic diagrams will be built from scratch. Each student will also learn to read schematic and pictorial diagrams and fully understand how to determine the sequence of operation of residential and commercial rooftop equipment. (Economizers will not be covered.) Class length 7 hour

This is a basic course for new heating/cooling service technicians, maintenance personnel, installers, wholesaler counter persons or sales persons. It teaches basic air conditioning concepts and is also valuable as a refresher for the experienced. Subjects include the refrigeration cycle, compressor function, metering device types, safe handling of refrigerants, using gauges for troubleshooting and reading and interpreting schematic diagrams. Workbook with troubleshooting charts is included. Class length: 7-hours, 8:30 am - 5:00 pm, Lunch provided. $200 per class if B-Y purchases are over $30,000 per year $240 per class if B-Y purchases are under $30,000 per year

EPA Certification This course is designed to provide basic training in preparation for EPA approved refrigerant handling certification. The course covers ozone depletion theory, the Clean Air Act, EPA Regulations, refrigerant recovery, recycling, recovery, safe refrigerant-handling and alternative refrigerants. Following the training the participants take the test which will be administered by a proctor. Class fee includes a study guide, 6 hours of professional instruction, examination administration and certification cards for those who pass the examination. Enrollees may become certified in Type I, Type II, Type III or Universal. Class length 8 hours

Students must have some air conditioning experience before taking this class. It is assumed that all participants know the basics. Students will learn how to calculate air flow across an evaporator coil, measure and adjust superheat, select replacement capacitors, wire hard start kits, charge and evacuate familiar and unfamiliar systems, fine tune, and troubleshoot electrical and refrigeration side problems. Class length 7 hours. Workbook & lunch provided.

Refrigerant R-410A is the current manufacturer's choice, replacing R-22 in residential and commercial air conditioning and heat pumps. It is important that contractors and technicians understand the safety, safe handling, proper charging, operating characteristics, service procedures and proper applications of this refrigerant. The newly designed R-410A systems employ thicker walled tubing, newly developed compressors and components, much higher operating pressures, and a higher grade oil that requires different installation and service procedures, and different evacuation procedures. R-410A is marketed under the brand names of Puron, Prozone, Suva 410a Gentron AZ-20 and many others. These newly manufactured R-410A systems will require contractors and technicians to shift to different tools and equipment, safety standards and fundamentals when installing, changing out (retrofitting) older split A/C systems and repairing systems in the field. This is a 4 hour course - 3 hours of lecture covering pre-examination review, followed by a 1 hour examination. Students passing the exam will receive R-410A certification.

This class is advanced and begins where Air Conditioning 2 ends. Students must have a working knowledge of the refrigeration cycle, test instrument usage, low voltage wiring and compressor replacement. This course will cover fan static pressure, determining correct fan speed and temperature drop. Compressor testing and troubleshooting, water-cooled condensers, water regulating valves, cooling tower operation, commercial controls and safety devices, sling psychrometer use and operation, psychrometric chart usage and its use in troubleshooting air-side problems and determining system capacity, phase monitoring, delta and wye transformer power sources including wild leg configuration and system cleanup after a compressor burnout will be covered in detail. Commercial system wiring diagrams will be explored to give the student better electrical troubleshooting and design skills. Calculator required.
