Sample GA HVAC Practice Questions

Try these sample questions to test your GA HVAC exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 132+ question experience with AI tutoring.

1Which practice best limits internal copper-oxide scale while brazing field-installed refrigerant tubing?

A.Flow a low-pressure dry-nitrogen purge through the tubing while brazing

B.Pressurize the tubing with oxygen while the torch is applied

C.Seal both tubing ends so heated air remains trapped inside

D.Flow moisture-bearing shop air through the tubing

Explanation: A low-flow dry-nitrogen purge displaces oxygen during brazing and limits oxide formation inside the refrigerant circuit. The completed piping still requires the manufacturer's specified pressure test, leak check, and evacuation.

2What should an installer do when terminating field power conductors at HVAC equipment lugs?

A.Tighten every lug by feel and ignore conductor material

B.Use any conductor size that physically enters the lug

C.Verify conductor material and size are listed for the terminal, prepare the conductor as specified, and torque the connection to the marked or instructed value

D.Tin all stranded conductors with solder before clamping them

Explanation: A power termination must match the terminal's listed conductor material and range and be tightened to the equipment or terminal torque specification. Correct preparation and torque reduce overheating without damaging the conductor or lug.

3What is the capacity limit for each complete system installed under a Georgia Class I conditioned air contractor license?

A.100,000 Btu/h heating and 48,000 Btu/h cooling

B.175,000 Btu/h heating and 60,000 Btu/h cooling

C.250,000 Btu/h heating and 120,000 Btu/h cooling

D.There is no capacity limit

Explanation: Rule 121-3-.04 limits each complete Class I system to not more than 175,000 Btu/h of heating and 60,000 Btu/h of cooling. Because 1 ton equals 12,000 Btu/h, 60,000 Btu/h equals 5 tons.

4Which Georgia agency administers employer unemployment-insurance tax accounts?

A.Georgia Department of Revenue

B.Georgia Department of Labor

C.State Board of Workers' Compensation

D.Secretary of State Professional Licensing Boards Division

Explanation: The Georgia Department of Labor administers the state's unemployment-insurance program and employer unemployment-tax accounts. The Department of Revenue administers other state taxes, while workers' compensation and professional licensure are handled by different agencies.

5What federal reporting deadline applies after a work-related fatality or severe injury?

A.Report every case within 30 days

B.Report a fatality within 8 hours and an inpatient hospitalization, amputation, or loss of an eye within 24 hours

C.Report only after the workers' compensation claim closes

D.Report severe events annually on the OSHA summary

Explanation: Federal OSHA requires covered employers to report a work-related fatality within 8 hours and a work-related inpatient hospitalization, amputation, or loss of an eye within 24 hours. These event reports are separate from routine injury-log and workers' compensation procedures.

6How are materials incorporated by a contractor into Georgia real property generally treated for sales-and-use-tax purposes?

A.They are always purchased tax-free for resale

B.The contractor is generally the consumer and owes applicable sales or use tax on the materials

C.The property owner always remits the material tax directly

D.Construction materials are categorically exempt from Georgia tax

Explanation: Georgia generally treats a contractor as the consumer of tangible personal property incorporated into real property. The contractor therefore pays sales tax to the supplier or accrues use tax when applicable, rather than treating the installed material as an ordinary retail resale.

7A space has a sensible cooling load of 10,800 Btu/h and a 20 F supply-to-room temperature difference. Using CFM = Qs / (1.08 x delta-T), what airflow is required?

A.300 CFM

B.400 CFM

C.500 CFM

D.600 CFM

Explanation: CFM = 10,800 / (1.08 x 20) = 10,800 / 21.6 = 500 CFM.

8What happens when moist air is sensibly cooled to its dew-point temperature and then cooled further?

A.Its humidity ratio rises immediately without condensation

B.Moisture begins condensing as further cooling continues

C.Its relative humidity falls below the starting value

D.Its dry-bulb temperature stops changing

Explanation: At the dew point, the air is saturated at its existing humidity ratio. Further cooling requires removal of water vapor by condensation, so both sensible and latent cooling occur.

9Which information belongs on a useful HVAC purchase order?

A.Only the supplier's trade name

B.Specified items and quantities, agreed prices, delivery terms, approval, and the receiving job or inventory account

C.Only the salesperson's verbal quotation

D.The customer's thermostat schedule but no material description

Explanation: A purchase order should identify what is authorized, the commercial terms, delivery expectations, and where the cost and received goods belong. Those details support receiving controls, inventory records, and job-cost accounting.

10Which ACCA manual is used to calculate residential heating and cooling loads?

A.Manual D

B.Manual J

C.Manual S

D.Manual Q

Explanation: ACCA Manual J is the residential load-calculation method. Manual D addresses residential duct design, and Manual S addresses equipment selection.
