Your home s air conditioner battles against all sorts of heat sunlight pouring through windows steam coming off the stove even family members and pets giving off body heat.
My ac unit is sideways in attic.
This allows sufficient time for any oils and lubricants to resettle back to their proper levels providing protection for internal gears and moving parts.
One reason that ac units go up in attics is because they re cheaper and easier to install.
In addition to making the unit hard to get to for service high attic heat can trigger the high pressure limit switch turning your condenser off.
Do not install sideways.
It s a lot simpler for your installer to leave ductwork loose rather than having to cover it and wind it through floors and walls.
But in homes with unventilated attics one of the greatest sources of heat may be the hot air trapped in the attic and radiating through the ceiling below.
If an air conditioner has been stored on its side or if it has been shipped that way take care to ensure it has been turned horizontally for a period of at least 24 hours prior to running the unit.
The copressor will burn up because the oil will run into the condesor coil and the moving parts of the compressor will not have any lubricatiuon.
