Sample Questions
Try a few questions to see what the full exam is like.
A heat pump has separate fixed restrictors and check valves for each mode. What is the purpose of the check valves? The site is a two-story house with the air handler in a vented attic. Outdoor temperature on arrival is 25 F, and the equipment serial suffix is HP127.
A packaged heat pump is being set on an existing roof curb. The unit base matches the curb, but the old gasket is compressed and there is a gap at one return-air corner. Which installation action is most appropriate? The outdoor unit sits on a snow stand near a wind-exposed corner. Outdoor temperature on arrival is 57 F, and the equipment serial suffix is HP018.
A technician is explaining the refrigerant circuit in heating mode. Which component is acting as the condenser on a standard air-to-air heat pump? The home has a media filter cabinet and flexible return duct in a closet. Outdoor temperature on arrival is 62 F, and the equipment serial suffix is HP050.
An outdoor unit repeatedly trips the breaker during defrost termination. Inspection finds the outdoor fan wires rubbed through at the coil guard and the fan restarts at termination. What is the proper service action? The site is a two-story house with the air handler in a vented attic. Outdoor temperature on arrival is 65 F, and the equipment serial suffix is HP035.
A technician is explaining the refrigerant circuit in heating mode. Which component is acting as the condenser on a standard air-to-air heat pump? The equipment is a 6-year-old split system with a communicating air handler. Outdoor temperature on arrival is 26 F, and the equipment serial suffix is HP146.
