Summary

This course covers the basics of servicing and troubleshooting air conditioning and refrigeration equipment, while expanding your knowledge of heating and ventilation systems ? and the electrical systems that control it all.

Workshop Description/Agenda

This is a 2-day classroom lecture version of our 5-day Lab course on HVAC.

When your HVAC system runs safely and efficiently, energy and maintenance costs are reduced. Learn how to maintain the peak efficiencies of your systems which will minimize the downtime spent on maintenance and maximize your energy efficiency.

This course covers the basics of servicing and troubleshooting air conditioning and refrigeration equipment, while expanding your knowledge of heating and ventilation systems ? and the electrical systems that control it all. Learn how to troubleshoot air conditioning system electrical and mechanical problems, and how to legally recover, recycle, and reclaim refrigerants. The program examines forced air furnaces and rooftop packaged systems, air movement and balance, fans, filters, pilot burner systems and flame safeguard devices. 

** NTT is a proctor for the HVAC Certification Exams? ESCO 608, 410A and Test of Excellence. If you are scheduled to take the test, you receive a free copy of the EPA Certification Exam Preparatory Manual.  Students MUST study before class to take the exam.

Hands-on and practical - look at what they are saying

"I really appreciate the experience and practical knowledge of the instructor. His real world experience and vast experience of so many HVAC systems gave every student answers to very site-specific conditions/applications. Thanks"
Dan Clark, US DOC/NOAA/NWS

"Info learned will be valuable in operating/troubleshooting/repairing our systems in the future. Our safety threshold has been raised significantly as well."
Don Ballow
