A portable air conditioner unit is an ideal ac for an attic as the exhaust conduit has a narrow exit end that s suited to fitting out a narrow window opening either vertically or horizontally or another small exhaust opening in the attic.
Istalling window ac unit in hall closet vent thru attic.
Exhausting it into a closet would be bad and wouldn t give you any net cooling in fact you d heat the system up from electricity consumption.
Put it in an attic full of blown insulation and you re forcing it to work harder to vent its heat.
They sit on the floor on casters and use an adapter kit to vent the hot air through a hose running through a window a wall or a sliding glass door.
So why put an hvac system up in the attic at all.
Attic hvac systems save space.
Well mainly it s a way to save space.
There are two options for venting a closet.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
If you aren t renting or you have an understanding landlord you could run rigid metal vent pipe into the attic and then up and trough the roof capping it with a vent cap.
The other option is to add a two way vent above the closet doors.
An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.
Portable air conditioners are similar to window units in operation.
I personally wouldn t want to go through the trouble of properly installing a through the wall unit on the third floor much less install an insulated cover on it in the cold months nor would i put a window unit in the front of the home.
Place the ac unit right in front of the hole you ve made with its exhaust hose or vent passing through the opening you cut into the exterior wall.
Btw a million dollars would buy a very nice home on the beach block of several communities around here.
You want to use rigid metal vent to reduce friction.
My only other option would be a split unit but the cost is pretty huge and i d also need to get a 220 circuit ran as most splits use.
It s important to make that opening no larger than necessary since you want to avoid having to pack in extra space with a lot of filler.
The first is to install an exhaust fan like those found in bathrooms.
While this will vent the closet it will also blow air into the attic and requires moving or adding duct work along with extensive electrical wiring.
Main advantages they are easy to install and use.
I can t vent via a window and am wondering how to exhaust the hot side of the ac unit.
