house was pretty new looking
i went to a couple of my relatives in california’s house
and all their air conditioning was located on the ATTIC
thats soo weird
cuz we usually just have them on the side of the house here

what a odd place to put them
it gets hot in the ATTIC
Are you talking about the AC unit of the HVAC system itself or just the other parts of the HVAC system?
HVAC comes in three parts: The AC unit consist of Condenser, compressor and fan that dissipate heat to the outside of the house (This is sometime refer to as ouside the home); the other unit include the evaporator, filter and blower that circulate cool air into the house; the third is the thermostat - regulate the air temp.(These are refer to as inside the home).
Install the HVAC system into the attic is done for labor cost mostly... and save space.
I have the AC unit outside my house and the other part in the basement.
