Home Inspection and HVAC Systems Quiz

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.

Definitions Related to Home Inspection

• 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.
