It is called a split system.
Attic based ac system.
If your attic tends to get hot it can make your air conditioner less efficient.
But with proper ventilation you can at least bring those temperatures down to match that of the outdoor air.
There is an outdoor and indoor unit.
Some people argue that the heat in your attic will warm the air your system has cooled before it even has a chance to move through the ducts in your attic and into the rest of your home.
With no air conditioning vents pumping in cool air and the hot sun beating down on the roof right over your head attic temperatures can soar.
To reset the switch you ll need to climb up into.
Typically this indoor unit gets placed in a cabinet or closet somewhere inside.
An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.
Aesthetically and practically speaking a bulky ac system in a small space like an attic is not only ugly and obtrusive but will also take up a space and even a sizable amount of elbow room.
In terms of energy use room air conditioners are not known for efficiency as well.
They consume to much energy.
Well mainly it s a way to save space.
Unless you have a finished attic you probably aren t fond of spending time up there during a hot summer day.
There is a cost effective and simple option to provide air conditioning to your attic without the cost and hassle of installing ductwork.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
