Section One — Questions 1–100
1. Which statement best describes the scope of work permitted under a Florida Class A Air
Conditioning Contractor license?
A) The contractor may perform any type of construction work, including plumbing and electrical
B) The contractor may work on HVAC systems of any size or tonnage without limitation
C) The contractor is limited to systems of 25 tons cooling and 500,000 BTU heating
D) The contractor may only perform service work, not new installations
Correct Answer: B) The contractor may work on HVAC systems of any size or tonnage without
limitation
Rationale: A Class A license is unlimited in scope, allowing work on any HVAC system regardless of
size or tonnage, distinguishing it from a Class B license which is capped at 25 tons cooling and
500,000 BTU heating. This makes Class A the most comprehensive HVAC contractor license available
in Florida. The unlimited capacity is the defining characteristic of the Class A license.
2. A Florida Class A contractor is preparing to install a new commercial HVAC system. Which agency
issues the contractor's license and has primary regulatory authority?
A) Florida Building Commission
B) Florida Department of Business and Professional Regulation (DBPR)
C) Florida Department of Environmental Protection
D) Local municipality building department
Correct Answer: B) Florida Department of Business and Professional Regulation (DBPR)
Rationale: The DBPR is the state agency responsible for issuing contractor licenses in Florida,
including Class A Air Conditioning Contractor licenses. The Construction Industry Licensing Board
(CILB) operates under the DBPR to oversee licensing and regulatory matters. Local building
departments handle permits and inspections but do not issue state contractor licenses.
3. What is the minimum age requirement to apply for a Florida Class A Air Conditioning Contractor
license?
,A) 18 years old
B) 21 years old
C) 22 years old
D) 25 years old
Correct Answer: A) 18 years old
Rationale: Applicants for a Florida Class A Air Conditioning Contractor license must be at least 18
years of age to apply. This is a basic eligibility requirement established by the DBPR and CILB. While
age 18 is the minimum, applicants must also meet experience, education, financial, and insurance
requirements to qualify for licensure.
4. How many years of HVAC experience are generally required to qualify for the Florida Class A Air
Conditioning Contractor license?
A) Two years
B) Three years
C) Four years
D) Five years
Correct Answer: C) Four years
Rationale: Applicants must demonstrate four years of HVAC experience, with at least one year in a
supervisory role. This experience can be verified through employers or, for self-employed individuals,
through tax records, invoices, or client testimonials. A combination of college education and
experience may also satisfy the requirement.
5. According to the Florida Class A exam outline, which topic area comprises the largest percentage
of the trade examination content?
A) Heating, Low and High Pressure Boilers
B) HVAC General
C) Ducts and Ventilation
D) HVAC Controls
Correct Answer: B) HVAC General
Rationale: HVAC General is the largest topic area on the Florida Class A trade exam, comprising
approximately 20% of the content. Other significant topic areas include Heating, Low and High
Pressure Boilers at 18%, with remaining content distributed across ducts, ventilation, controls, and
other technical areas. This weighting reflects the comprehensive nature of the unlimited Class A
license.
6. A contractor is studying for the Business and Finance portion of the Florida Class A examination.
Which topic is most likely to appear on this exam segment?
A) Refrigeration cycle components
B) Load calculation methodologies
,C) Contract law and construction liens
D) Duct sizing and air distribution
Correct Answer: C) Contract law and construction liens
Rationale: The Business and Finance exam covers contract law, liens, workers' compensation, general
liability insurance, Florida Statutes Chapters 455 and 489, CILB rules, and financial responsibility.
Technical topics such as the refrigeration cycle, load calculations, and duct design are tested on the
trade knowledge exam, not the business portion.
7. During a new installation, the owner requests additional ductwork not included in the original
contract. What is the contractor's most appropriate response?
A) Perform the work and invoice the owner later
B) Execute a written change order defining the scope, pricing, and responsibilities
C) Proceed based on the owner's verbal authorization
D) Refuse the additional work until the original contract is completed
Correct Answer: B) Execute a written change order defining the scope, pricing, and responsibilities
Rationale: A written change order protects both parties by documenting the scope change,
establishing pricing, and defining responsibilities. Verbal authorization lacks legal protection, and
proceeding without documentation exposes both contractor and client to disputes. A comprehensive
change order reduces risk and ensures clarity for all parties involved.
8. Which of the following is an approved reference permitted in the Florida Class A exam testing
center?
A) Any HVAC textbook the candidate chooses
B) Personal notes prepared before the exam
C) The Florida Building Code - Mechanical
D) Unmarked copies of any code book
Correct Answer: C) The Florida Building Code - Mechanical
Rationale: The Florida Building Code - Mechanical is one of the approved references permitted in the
testing center. Candidates may bring specific code books and reference materials as identified in the
exam's reference list. Personal notes and unapproved textbooks are not permitted, and all materials
must comply with testing center rules.
9. Which NFPA standard covers the installation of air conditioning and ventilating systems?
A) NFPA 70 (National Electrical Code)
B) NFPA 90A
C) NFPA 96
D) NFPA 101 (Life Safety Code)
Correct Answer: B) NFPA 90A
, Rationale: NFPA 90A covers the Installation of Air Conditioning and Ventilating Systems and is one of
the approved references for the Florida Class A exam. NFPA 70 is the National Electrical Code, NFPA
96 covers commercial kitchen ventilation, and NFPA 101 addresses life safety requirements.
Understanding these distinctions is important for code compliance.
10. A contractor is replacing a rooftop condensing unit. Which consideration is most important for
long-term serviceability?
A) Concealing all access panels for aesthetic purposes
B) Providing adequate service clearance around the equipment
C) Positioning the unit directly against a parapet wall
D) Locating electrical disconnects inside the occupied space
Correct Answer: B) Providing adequate service clearance around the equipment
Rationale: Proper service clearances facilitate maintenance, improve safety, and allow technicians to
inspect and repair equipment effectively. Concealing access panels or positioning units against walls
creates obstacles that increase costs and safety risks. The Florida Building Code and manufacturer
instructions specify required clearances that must be followed.
11. What is the minimum passing score required for the Florida Class A Air Conditioning Contractor
trade examination?
A) 65%
B) 70%
C) 75%
D) 80%
Correct Answer: B) 70%
Rationale: The Florida Class A trade examination requires a minimum passing score of 70%. The
Business and Finance examination also requires 70% to pass. Candidates must achieve the passing
score on each exam section independently to obtain licensure. Failing one section requires retaking
only that portion.
12. A contractor is reviewing project documentation requirements. Which document is most
valuable for verifying that installed equipment matches contract 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
Rationale: Approved submittals verify equipment characteristics, capacities, dimensions, and
compliance with contract documents. Receipts and delivery tickets confirm purchase and delivery but
