standards, and approved plans
C. To determine the age of the building
D. To recommend a specific equipment manufacturer
Answer: B. To verify that HVACR work complies with applicable codes,
standards, and approved plans
Rationale: An HVACR inspection is primarily a code-compliance activity.
The inspector evaluates installations, equipment, materials,

A. Contractor's business card
B. Approved plans and specifications
C. Equipment sales receipt only
D. Property tax statement
