Licensing Laws & Business Practices (Questions 1–6)
QUESTION 1.
A contractor is preparing a proposal for a commercial HVAC replacement project.
Which action best demonstrates compliance with professional contracting practices
before work begins?
A. Begin work after receiving verbal authorization.
B. Order equipment immediately to avoid price increases.
C. Execute a written contract defining scope, pricing, responsibilities, and change-
order procedures.
D. Wait until equipment arrives before documenting project details.
Correct Answer: C. Execute a written contract defining scope, pricing,
responsibilities, and change-order procedures.
Explanation: A comprehensive written contract reduces disputes, establishes legal
obligations, defines project expectations, and documents procedures for modifications.
Verbal authorization offers insufficient protection, while ordering equipment or
delaying documentation exposes both contractor and client to unnecessary risk.
QUESTION 2.
During construction, the owner requests additional ductwork not included in the
original agreement. What is the most appropriate response?
A. Perform the work and invoice later.
,B. Decline the request entirely.
C. Prepare a written change order documenting scope, cost, and schedule impacts
before proceeding.
D. Include the additional work in the final invoice without documentation.
Correct Answer: C. Prepare a written change order documenting scope, cost, and
schedule impacts before proceeding.
Explanation: Written change orders provide legal clarity, document mutual agreement,
and prevent disputes regarding pricing or project completion. Performing
undocumented work often leads to payment disagreements.
QUESTION 3.
A contractor discovers that a required mechanical permit has not yet been issued.
What is the most appropriate course of action?
A. Begin installation because permitting is primarily an administrative matter.
B. Delay work until the appropriate permit has been obtained.
C. Complete only refrigerant piping.
D. Install equipment but postpone inspections.
Correct Answer: B. Delay work until the appropriate permit has been obtained.
Explanation: Mechanical permits are generally required before regulated work begins.
Starting work without proper authorization may result in penalties, failed inspections,
and project delays.
QUESTION 4.
Which document most effectively demonstrates that installed HVAC equipment
satisfies the project specifications?
, A. Purchase receipt
B. Manufacturer's submittals and approved shop drawings
C. Employee time sheets
D. Delivery ticket only
Correct Answer: B. Manufacturer's submittals and approved shop drawings.
Explanation: Approved submittals verify equipment characteristics, capacities,
dimensions, and compliance with contract documents. Receipts and delivery tickets
alone do not confirm specification compliance.
QUESTION 5.
An HVAC contractor delegates supervision of a complex installation. Which
responsibility generally remains with the licensed contractor?
A. Daily tool inventory
B. Overall responsibility for code compliance and workmanship
C. Scheduling employee vacations
D. Equipment shipping arrangements
Correct Answer: B. Overall responsibility for code compliance and workmanship.
Explanation: Although supervision may be delegated operationally, the licensed
contractor remains accountable for ensuring work complies with applicable regulations
and professional standards.
QUESTION 6.
Project documentation is most valuable because it:
A. Eliminates the need for inspections.
