Course Information

The student will follow along with a Certified Master Inspector® as he performs several inspections of HVAC systems. Upon successful completion of this course, the student should be able to:

properly inspect an HVAC system by applying visual-only inspection procedures and defect-recognition techniques;
inspect, describe and identify the HVAC system using normal operating controls; and
write a report identifying material defects observed.

Heating and cooling systems are taken apart to demonstrate how they work. Actual inspections are performed on numerous HVAC systems, including boilers, furnaces and heat pumps. A gas-fired furnace is taken apart to reveal a cracked heat exchanger defect.

Course Topics Include:

central heating systems;
various types of furnaces, including gas, oil, electric, solid fuel, air distribution systems, and filtration systems;
classifications, efficiencies and categories;
major components;
heat exchangers, blowers, controls and electronics;
pilots, ignitors, flame sensors, fan/limit controls, and safety devices;
sequence of operation;
types of boilers, including water, steam, oil, gas, wood, coal, and electric;
forced-draft, natural-draft, and induced-draft;
condensing units, including wall-hung and integrated;
zone valves, mixing valves, water cutoffs, circulators, air separators, temperature/pressure controls, limit controls, backflow, and tanks;
oil burners;
piping systems and hydronic heat distributions systems;
heat pump systems, including their components, cycles and operation;
thermostats and controls;
ventilation, air filtration, humidification, dehumidification, and air circulation;
chimneys and venting systems, including masonry, fabricated, vent pipes, types and categories, plastic, direct, and unvented;
in-space heating systems, including room, wall, floor, electric, fireplaces, stoves, and infrared heaters;
humidification devices and systems, including induct, bypass, portable and specialty;
central cooling systems, including the refrigeration cycle, compressor, condenser, fan, metering devices, valves, evaporator and coils;
