Watch First: Fast Overview
Start with this quick walkthrough, then use the guide below as your roadmap. Bookmark the Florida Air A collection and the Air B trade course so every resource is one click away while you study.
What These Exams Actually Test
The Air A and Air B trade exams check whether you can design, size, install, and troubleshoot HVAC systems in Florida using current references. You will see questions about load calculations, duct design, equipment selection, refrigeration cycle, electrical, controls, fuel gas, code navigation, safety, and system startup. Air A covers unlimited tonnage statewide. Air B is typically limited to 25 tons cooling and 500,000 BTU heating per system. Prepare with aligned Air A exam prep, Air B exam prep, and curated book sets.
Your 6-Week Study Blueprint
Weeks 1–2: Fundamentals
- Gather approved references or a convenient Air A book rental or Air B rental.
- Refresh HVAC math: BTU, CFM, sensible vs. latent, psychrometrics, fan laws.
- Daily drills with targeted cram practice to build speed.
Week 3: Sizing and Design
- Load calcs, duct friction, equivalent length, diffuser selection.
- Equipment selection and matching; economizers and ventilation basics.
- Timed sets with a calculator and your index open.
Week 4: Codes and Safety
- Mechanical code, fuel gas, electrical fundamentals, clearances, combustion air.
- Tab high-yield tables using pre-printed tabs.
- Run mixed-topic quizzes to strengthen navigation.
Week 5: Controls and Troubleshooting
- Control strategies, sequence of operation, sensors, and safeties.
- Common faults: superheat, subcooling, airflow, electrical diagnostics.
- Alternate with light review of Business and Finance using an online course.
Week 6: Two full timed practice tests. Review every miss with books open. Write a one-page fix list, then retest until you consistently hit your target score. Keep your books arranged exactly like exam day.
Build Your Open-Book Toolkit
Create a lean setup that mirrors test day. You want fast lookups and clean notes. Use tabs, a short index, and a highlighter strategy that does not coat every page.
- Tabbed primary references with clear section flags.
- A front-page HVAC index with 30 to 40 keywords and page numbers.
- Sticky-note quick math for fan laws, friction, sensible heat, superheat, subcooling.
- A one-page code table cheat sheet for clearances and combustion air.
If you want a ready-to-go bundle, consider curated packages that pair books with practice.
Exam-Day Game Plan
- Set your pace. Divide questions by minutes and set a per-question buffer. Flag guess-and-go items.
- Scan the ask. Read the last sentence, peek at choices, then jump to the exact section.
- Use your index first. Avoid wandering. Find the keyword and go straight to the page.
- Do clean math. Write the formula, plug numbers, and verify units.
- Two passes. First pass for the easy 70 percent. Second pass for flagged items.
High-Yield Topics To Master
Airflow and Loads
- Sensible heat equation, CFM targets, coil approach.
- Duct sizing, friction rate, fittings, and equivalent length.
- Ventilation and outdoor air mixing.
Refrigeration and Electrical
- Superheat, subcooling, TEV behavior, charging logic.
- Motors, starters, overcurrent protection basics.
- Controls, safeties, and sequences of operation.
Codes and Fuel Gas
- Mechanical code tables and clearances.
- Combustion air and venting rules.
- Placement, access, condensate, and smoke control basics.
Test Strategy
- Open-book indexing and tabbing tactics.
- Mixed-topic sprints to simulate fatigue.
- Error logs and quick re-tests on weak areas.
Use aligned online courses and practice exams to rehearse exactly what appears on test day.
Sample Problems To Practice
- Airflow: A 4-ton system with 30 percent OA targets what supply CFM at 400 CFM per ton, and what mixed air temperature given indoor and OA conditions.
- Duct friction: Given 1.0 in. total ESP and device losses, compute allowable friction rate and choose a main trunk size.
- Superheat: With measured suction pressure and line temperature, find target superheat and diagnose undercharge vs. low airflow.
- Combustion air: Determine required volume and opening sizes using the code table provided.
Turn these into 10-minute sprints. Short, daily reps beat long, occasional crams.
Your Materials Checklist
- Approved references with tabs and a clean index.
- Calculator with fresh batteries and a quiet timer.
- Pencils, highlighter, sticky flags, and your exam confirmation.
- Optional: structured prep package for full simulations.
If you still need resources, start with the Florida Air A collection and add the specific Air B course as needed.
