Heating Inspections
Objective: Permanently installed heating systems, whether central, multiple zone, or area, will be covered. The basic components of central heating systems illustrated are: a safe container, a heat exchanger, disposal system, distribution system, heat outlets and temperature and safety controls. The common types covered are gas, oil, hot air, hot water, steam, electric radiant and electric baseboard systems.
Identify the heating system’s location and fuel type. Determine the furnace age and capacity. Identify the method of heat distribution. Identify and describe fuel source. Learn to evaluate and describe heat exchanger. Understand how to identify proper venting. Learn how to recognize adequate combustion air. Identify and evaluate humidifier units. Identify and describe air filter units. Identify the location and type of supplemental heat.
Venting of noxious gases from carbon monoxide, due to improper combustion air requirements, and the proper overall venting of each system is covered in great detail. Consequences of improper venting will be covered through many illustrations.
Evaluation of the systems will be explained through methods and procedures. Proper tools needed to inspect will be discussed along with methods and procedures using them. Smoke detectors, carbon monoxide detectors, and gas detectors will be demonstrated along with additional use of other helpful items.
PLI employs an extensive lab of equipment types and hands-on opportunities in presenting these materials (see photos). Appropriate reporting methods are covered and examples supplied.
Air Conditioning Inspections
Air conditioning and heat pumps will be thoroughly discussed with the help of illustrations and instruction. In the heat pump and cooling mode of operation, the system will be examined for the different pressures and temperatures encountered during the operation of both modes. The refrigerant cycle and how it relates to residential cooling will be covered. Discussions will cover window and built-in wall units but they are not performed according to the methods of national standards of practice.
Identify the AC system’s location and fuel type. Determine the AC system’s age and capacity. Identify the method of cool air distribution. Identify the system’s Electrical disconnect location. Describe the cool air distribution components.
Proper and necessary tools to perform the evaluation on the cooling systems will be covered, such as, thermometers and ammeters.
