Computer Room Cooling Systems

Server rooms and computer equipment rooms have unique air conditioning needs.  The special units designed to meet those needs are very similar to conventional air conditioning systems, but they are just different enough to get you into trouble if you’re not careful.  This seminar will reveal the unique features of computer room AC (CRAC) systems and bring the conventional AC technician up to speed on how to service these specialized systems.

Dual Fuel Heat Pump Systems

Even though outdoor air temperatures are cool in winter, the outdoor air still has heat available.  The heat pump takes advantage of that fact and absorbs heat from the outside air and deposits it indoors through a refrigeration system.  In cool mild outdoor conditions, the heat pump will heat at a lower cost than a gas furnace.   This HVAC Service Mentor seminar will teach students the vitals about Dual Fuel Heat Pump Systems using a gas furnace as a backup heat source.

Electric Motors For HVAC

A thorough understanding of the operation of electric motors is vital to the diagnostic technician.  This HVAC Service Mentor seminar will teach students to understand, diagnose, and troubleshoot “The Six” major types of electric motors in the HVACR trade in both residential and commercial applications.

Electrical Schematics

Troubleshooting heating or cooling systems usually involves working on electrical circuits.  Reading and understanding electrical schematics is an essential skill for the HVACR service technician.  This class will help students reach a higher level of understanding of electrical circuits and schematics by walking through several common schematic diagrams from actual heating and cooling systems found in the field.  Technicians of all skill levels will benefit to attend.
