Identify the type of refrigerant that is commonly used in residential air conditioning systems.

• R-12

• R-22

• R-134a

• R-410A

Which tool is necessary for measuring the vacuum level during the evacuation process of an HVAC system?

• Pressure gauge

• Vacuum pump

• Micron gauge

• Thermometer

What is the primary purpose of the EPA's regulatory compliance guidelines for HVAC technicians?

• To increase the cost of HVAC services

• To ensure the safety of technicians

• To protect the environment from refrigerant emissions

• To standardize HVAC equipment

During the recovery process, why is it important to identify the type of refrigerant in the system?

• To determine the correct recovery machine settings

• To decide the color of the recovery cylinder

• To calculate the system's cooling capacity

• R-134a

• R-22

• R-404A

What is the role of a vacuum pump in the evacuation process of an HVAC system?

• To add refrigerant to the system

• To remove air and moisture from the system

• To measure refrigerant pressure

• To cool the refrigerant

Which of the following is a requirement for HVAC technicians under the EPA's Section 608 certification?

• Ability to design HVAC systems

• Knowledge of refrigerant recovery and recycling

• Experience in electrical wiring

• Proficiency in welding

When recovering refrigerant from a system, why is it important to use a recovery cylinder instead of a regular storage tank?

• Recovery cylinders are cheaper

• Recovery cylinders are designed to withstand high pressure

• Recovery cylinders are lighter

• Recovery cylinders are color-coded

Which refrigerant type is known for having a low Global Warming Potential (GWP) and is considered environmentally friendly?

• R-22
