A dwelling’s occupants need adequate heating and cooling for its intended use in this climate. Which datum most directly addresses the functional utility of that system?
Correct Answer
C) The supported adequacy and condition of the heating/cooling system
For the stated dwelling and climate, inadequate heating/cooling capacity directly affects functional utility and may require qualified evaluation. Other systems can be material too; there is no universal ranking from brand or age alone. An appraiser does not replace a technical system inspection.
Why This Is the Correct Answer
Option C is correct because the supported adequacy and condition of the heating and cooling system directly shows whether it meets occupants' needs for the intended use and climate. Inadequate heating or cooling capacity affects functional utility and may require qualified evaluation.
Why the Other Options Are Wrong
Option A: The location of the main water shutoff valve and the age of the plumbing
Option A, the location of the main water shutoff valve and the age of the plumbing, concerns the plumbing system. It does not address whether the heating and cooling system is adequate.
Option B: The electrical-panel brand alone
Option B, the electrical-panel brand alone, says nothing about heating and cooling adequacy. A brand name by itself also does not establish the condition or performance of any system.
Option D: The water heater’s age alone
Option D, the water heater's age alone, concerns domestic hot water, not space heating and cooling. Age alone also does not establish a system's adequacy or condition.
Match the system to need
If the concern is comfort heating and cooling, look at the heating and cooling system's adequacy and condition.
How to use: Use this to pick data that answers the specific functional question asked.
Exam Tip
Choose the datum that directly measures the stated need, and be wary of options using a single attribute like brand or age alone.
Common Mistakes to Avoid
- -Judging system adequacy from brand or age alone
- -Confusing water heating with space heating
- -Treating the appraisal as a technical system inspection
Concept Deep Dive
Analysis
This question tests matching a functional-utility concern to the data that addresses it. The stem focuses on occupants' heating and cooling needs in this climate, so the most direct information is the adequacy and condition of the heating and cooling system.
Background Knowledge
Functional utility reflects how well a property serves its intended use according to market standards, including adequacy of mechanical systems. When market resistance arises from inadequate heating, plumbing or electrical services, the appraiser addresses the effect on value and marketability.
Real-World Application
In a hot-summer market, an appraiser notes that a house has only window units serving part of the living area while competing homes have central air. The appraiser reports the adequacy issue and analyzes market reaction to the deficiency.
