Hot Attic Air Conditioning

So why put an hvac system up in the attic at all.

Hot attic air conditioning.

Typically this indoor unit gets placed in a cabinet or closet somewhere inside. With that said a room air conditioner with just a nominal or average cooling capacity even if rightly sized will be forced to work harder. Well mainly it s a way to save space. A portable air conditioner is the easiest solution for cooling your attic.

Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. My idea is to vent the build up of hot air that has risen to the ceiling in the hotspot rooms into the attic so that air from cooler parts of the house can move in. Cool air in hot air out attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. Low cfm similar to a bathroom vent 300cfm and only in the hot spots basically by adding an inline ducting fan to the return ducts for the hotspot rooms.

It s a standalone unit that s about two feet tall and 18 inches wide and has wheels for mobility. Mini split ductless air conditioner. Portable air conditioners do need to be vented to pump the hot air outside. And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature.

An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be. An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate.
