Study Notes

Home Inspection Safety and Procedures

In case of detecting a strong gas smell, vacate the premises and notify the appropriate authorities immediately.
Dangerous or adverse situations require special safety equipment and may pose injury risks to inspectors.

Refrigeration and Air Conditioning Components

The expansion device converts high temperature, high pressure liquid refrigerant into low temperature, low pressure liquid.
The condensing coil transforms high temperature, high pressure gas into high temperature, high pressure liquid.
The evaporator coil changes low pressure, low temperature liquid refrigerant into low temperature, low pressure gas.
The compressor converts low pressure, low temperature gas into high temperature, high pressure gas.

Safety Measures and System Components

Automatic safety controls protect systems from extreme pressures, temperatures, and various hazardous conditions.
Central air conditioning systems distribute cooled air using ducts or chilled water to multiple rooms, excluding plug-in units.
A component in home inspections refers to observable aspects like walls or floors, rather than individual parts like nails.

Cosmetic damage includes visible defects that do not affect the functionality of the system or component.
A cross-connection is any arrangement linking potable water to potential contamination sources.
Functional drainage is characterized by timely empting without overflow during simultaneous use of other fixtures.
Functional flow ensures reasonable water flow at the highest fixture during concurrent operations of other fixtures.

Space and Inspection Regulations

Habitable space refers to areas designated for living, sleeping, eating, or cooking, excluding bathrooms, closets, and storage areas.
The term "inspect" refers to making a visual examination of all visible components.
Installed items require tools for removal, indicating a fixed connection.
Normal operating controls are devices operated by homeowners, such as thermostats and switches.

Accessibility and Visibility in Inspections

Readily accessible panels are designed for easy homeowner inspection with removable fasteners, reachable from a standard ladder without obstruction.
Readily visible components can be seen with basic lighting, negating the need for specialized tools beyond a flashlight.

Sampling and Representation in Inspections

A representative number method means inspecting one component per room for identical items, and one per side for external components.
The roof drainage system includes essential components like gutters and downspouts which ensure effective water management.
