AC Components
This component moves air through the home’s ductwork.
What is the blower motor?
Homeowners should regularly replace or clean this item to help airflow
What is the filter
A dirty filter can cause what to happen to the indoor evaporator coil
Ice Up / Freeze Over
The air-conditioner needs this in order to make cold air and cool the home?
what is refrigerant
This device controls the home’s heating and cooling settings
what is the thermostat
This outdoor component releases heat from the refrigerant.
What is the condenser coil/unit
Maintenance technicians use a hose & water to clean this unit
What are condenser coils/unit
A plugged evaporator coil drain line will cause what to happen?
The air filter goes on which side of the system, the return or supply side?
what is the return
A dead version of this small power source can stop some thermostats from working
What is batteries
This component helps start and run the compressor and fan motors.
What is the capacitor
This is connected to the indoor evaporator coil, technicians will make sure this is clean/clear to prevent condensation water from leaking
What is the condensate drain line
If a client calls in and says their AC system is iced up...
What is the first steps they should take before we can send out a technician?
Install a new filter, turn the AC off at thermostat, and turn on the fan until the system thaws out...
Technicians cannot perform any diagnosis until the system has thawed
This component is on the outdoor unit and it removes heat from the refrigerant
what is the condenser fan motor / outdoor fan motor
What are the 2 settings for the fan at the thermostat?
Auto & On
This indoor coil absorbs heat from inside the home.
What is the evaporator coil?
This reading is taken with a thermometer, and it is the difference between return air temp & supply air temp
Temperature Split / Delta T
If a client says the indoor unit/furnace is running, they feel only warm air from the vents, but the outdoor unit is not operating...what is most likely the issue?
Bad/Failed dual run capacitor in the condenser unit
Clients should not set the thermostat below what temperature to prevent damaging the compressor and icing up the AC system?
what is 68 degrees
If the fan is set to “On” at the thermostat, the indoor fan/blower motor will do what?
Run continuously
This component pumps refrigerant through the air conditioning system
What is the compressor
Technicians hook up their gauges on the outdoor condenser unit to check these readings?
Operating Pressures or Refrigerant Charge/Levels
If a client complains the thermostat is set for cooling, the indoor, and outdoor units are running, but they feel only warm air from the vents, and the thermostat will not reach the set temperature....What is most likely the issue?
Low Refrigerant
What are 3 pieces of equipment that could be considered an air-conditioner?
Split system AC, Heat Pump, Mini-Split
This thermostat setting allows the fan to run only during heating and cooling cycles
What is Auto
