  • Why You should take this seminar

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

    This HVAC training seminar 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.

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