AK HVAC study guide
AK HVAC · Work through your exam, one topic at a time.
The Alaska HVAC exam is a licensing assessment used by the state to evaluate whether a contractor applicant has the trade knowledge and business understanding needed to hold a mechanical/HVAC contractor credential in Alaska. It is aimed at people who already have field experience and are moving into qualifying or running a contracting business, not at entry-level technicians seeking a first job. The AK HVAC study guide has 8 sections and about 2,314 words.
01General HVAC Knowledge and Fundamentals
Start with the physics that every other domain rests on: heat flows from warmer to cooler bodies by conduction, convection, and radiation, and the job of HVAC equipment is to manage that flow. Candidates must be fluent in sensible versus latent heat, the difference between temperature and heat content, and the fact that a Btu raises one pound of water one degree Fahrenheit.
310 words, about 2 min02Heating Systems and Equipment
This domain covers furnaces, boilers, and the controls that keep combustion safe. Know the difference between induced-draft, natural-draft, and condensing appliances, and why condensing units achieve higher efficiency by recovering latent heat from flue gas (flue temperatures low enough to condense water vapor).
294 words, about 1 min03Ventilation and Air Distribution
Ventilation and distribution questions test whether you understand how air actually moves through a building and why it must be replaced. Cover the three ventilation strategies - exhaust-only, supply-only, and balanced - and know that balanced systems (HRV/ERV) are preferred in tight, cold-climate homes because they control both pressurization and heat recovery.
298 words, about 1 min04Air Conditioning and Refrigeration
Refrigeration is a cycle, not a mystery: compress, condense, meter, evaporate. Know the four components and the state of refrigerant at each - low-pressure vapor into the compressor, high-pressure vapor out, liquid after the condenser, and a low-pressure liquid/vapor mix after the metering device.
267 words, about 1 min05Piping, Ductwork, and Insulation
This domain rewards attention to details that show up in field failures. For piping, know material compatibility, support spacing, expansion and contraction, and the difference between schedule 40 and thinner-wall pipe.
300 words, about 2 min06Electrical and Controls
Electrical questions test safety and practical troubleshooting more than code minutiae. Know Ohm's law and the power equation (P = V × I), the difference between AC and DC, and how a basic circuit works: source, switch, load, return.
284 words, about 1 min07Safety, Tools, and Code Compliance
Safety is not a separate topic - it is threaded through every task. Know personal protective equipment for the job, lockout/tagout, and the hazards specific to HVAC: refrigerant frostbite and asphyxiation in low spaces, carbon monoxide, electrical shock, and fall hazards.
271 words, about 1 min08Alaska Business, Law, and Licensing
The Alaska-specific domain tests whether you can operate legally and professionally in the state. Know that mechanical and HVAC work is regulated, that contractor registration and licensing requirements apply, and that working outside your license scope carries penalties.
