I need some basic info about A/C and heating units. I have 2 in one A/C heating unit and I am trying to identify what is what?
I have a big machine inside my closet and one unit is outside with a fan.
For Heating
What is the role of
Heat pump
furnace
where they are usually located?
In general A/C has 3 parts, where they are located?
Condensor-- should be inside? does it part of furnace?
compressor - I think outside
fan -- to cool off warm freon form inside
What is HVAC system? Does every centeral A/C and heating is HVAC?

Hmmm...in a nutshell. Heating, Ventilation, and Air Conditioning make up HVAC.
A/C parts:
Compressor - outside
Condensor coil - outside
Condensor fan - outside
Evaporator coil - inside
Evaporator fan - inside
Furnace:
Fan and heating element or burner. Often combined with A/C parts inside so that an additional fan is not necessary.
The big box in your closet is commonly called an air handler, and the parts outside a condensor unit.

what is the role of heat pump and furnace?
I assume heat pump is outside? is this combined with AC compressor?
How to tell energy efficiency of a heating unit?
Inside my closet unit (furnace) it say 24000 BTU which I assume is 2 tons units. This 2 tons are for both heating and air conditioning or just for AC?

Furnace is a term usually associated with a heating only unit. Modern system employ gas or electric and include a modular design to incorporate it within the A/c air handler.

From what you say that furnace could be a heatpump. Is there a vent pipe on it, a gas line in iron pipe? All a heat pump is is like a AC system. And we just say put the inside coil outside and the outside coil in side in winter Thats a heat pump. Or Take a window ac unit out of a window in winter and turn it around. Thats a heat pump.

Thanks guys
In the new HVAC units (both ac and heating) every thing is outside or some thing has to be inside too?
What makes most noice, inside or outside? My both inside and outside units are making like engine like noice.
How to tell energy efficiency for heating? I assume SEER is for air conditioning.

You are right in SEER is for AC
And AFUE is for the furnace
