Try these questions from our free Residential Air Conditioning Systems Mechanic Certification practice tests. The correct answer and an explanation follow each question.
Which refrigerant is classified as an HFC and is commonly used in residential air conditioning systems manufactured after 2010?
Answer: B. R-410A
R-410A is an HFC refrigerant that replaced R-22 in residential AC systems due to its zero ozone depletion potential.
What is the standard control voltage used in most modern residential air conditioning systems for the thermostat and safety circuits?
Answer: B. 24 VAC
Residential HVAC systems use a step-down transformer to convert line voltage (120V or 240V) to 24 VAC for the control circuit. This lower voltage is safer for the wiring that runs to the thermostat and through various safety switches.
When connecting refrigerant gauges to a pressurized residential air conditioning system, what is the minimum Personal Protective Equipment (PPE) a technician must wear to protect against the most immediate hazards?
Answer: B. Safety glasses with side shields and gloves
The primary hazards when connecting gauges are high-pressure spray and contact with liquid refrigerant, which can cause severe eye injury and frostbite. Therefore, safety glasses with side shields (or goggles) and insulated or leather gloves are the minimum required PPE to protect against these immediate risks.
Which safety standard specifically addresses electrical requirements for motor-compressors and their associated control equipment in air conditioning systems?
Answer: B. NEC Article 440
NEC Article 440 specifically covers hermetic refrigerant motor-compressor electrical requirements, including conductor sizing, overcurrent protection, and disconnect means.
