Is not having a cooling system a reportable deficiency? ✔Correct Answer-No, it's not
considered a deficiency because a home is not required to have one.
Note:
- Consider reporting absent cooling system if standard in area
Are cooling systems part of a home inspection? ✔Correct Answer-Answer:
- Yes, if the cooling system is a permanent installation.
What are the 4 basic types of AC systems? ✔Correct Answer-1) Central air conditioner
2) Window Air Conditioner
3) Split air conditioner system
4) Ductless mini-split systems
5) Evaporator coil (A.K.A., swamp cooler)
Air conditioning ✔Correct Answer-- Refers to the cooling, dehumidification, ventilation, and
air filtration functions
What are the 3 major parts of an air conditioning system? ✔Correct Answer-System that
includes:
1) Air handler or furnace
2) An evaporator coil,
3) Condenser unit
How does an air conditioning system work? ✔Correct Answer-- Cools by removing heat from
house and moving heat to outside
Air handler ✔Correct Answer-- Inside unit of heat pump
What are the 3 parts of an air handler? ✔Correct Answer-1) Fan,
2) Evaporator coil,
3) Associated controls & operating parts
Boot (HVAC distribution system) ✔Correct Answer-- Sheet metal formed into rectangle or
circle that connects air duct to grille or register
, British thermal unity (Btu) ✔Correct Answer-- Amount of heat required to increase
temperature of 1 pound of water by one degree
- i.e., common description of size or cooling capacity of AC system
Collar ✔Correct Answer-- Round sheet metal ring that connects duct to plenum or trunk duct
Compressor ✔Correct Answer-- Part of air conditioner or heat pump condenser unit
- Compressor compresses gas refrigerant into superheated gas
- Provides energy to move refrigerant through system
Condensate ✔Correct Answer-- Water condenses into liquid when heat is removed by air
flowing over evaporator coil
- Lots of water in humid environments (e.g., Florida)
- Water must be disposed of in appropriate manner
Condenser coils ✔Correct Answer-- Tubes (i.e., coils) around perimeter of condenser unit
Condenser unit ✔Correct Answer-- Outside unit of split AC or heat pump
What are the parts of a condenser unit? ✔Correct Answer-1) Compressor,
2) Condenser coils,
3) Fan,
4) Controls, &
5) Operating parts
Damper (HVAC duct system): ✔Correct Answer-- Plate in a duct system that controls air flow
in ducts
- May be controlled manually or by motor
- In zoned systems, motor controlled dampers are controlled by two or more thermostats
Evaporator coil ✔Correct Answer-- Part of HVAC
- Located in air handler of heat pump or furnace after combustion chamber
- Should not be located before combustion chamber (i.e., moist air can damage furnace)
heat pump ✔Correct Answer-- HVAC component that removes heat in cooling mode or adds
heat in heating mode
Heat seasonal performance factor (HSPF) ✔Correct Answer-- Measure of efficiency of heat
pump in heating mode
- HSPF = heat output over heating season / electricity used
- HSPF is usually between 7 - 10
Latent load ✔Correct Answer-- Amount of heat energy AC must remove from inside because
of vapor in air
