Attic Too Hot For Ac Unit

I plan on adding a ductless heat ac unit.

Attic too hot for ac unit. Install electric ventilators and attic fans which remove hot air from an attic. An ac unit will keep the temperature much more pleasant and comfortable for you to be in your attic for long periods of time. We are in the process of converting the attic to living space. There s one more way that you can vent a portable ac unit and get rid of that hot air in a windowless room.

You can pipe the hot air out through a chimney. Excessive heat deteriorates items you store in the attic and can cause moisture. Ideal attic temperatures shouldn t be more than 10 to 20 degrees hotter than outside temperatures. Signs that the attic is too hot the attic should have a uniform flow of air circulating from the outside through the attic to exhaust the rest of the house.

In the summer it gets to about 90 outside and over 130 in the attic during the peak of the day. I live on long island ny. As the ac. I installed 3 large windows.

A hot attic is bad for several reasons. As for attic air conditioners you have two best options without a window. Another problem with vaulted ceilings at least here in the southeast is that builders use tradeoffs to put in less insulation than is required for flat ceilings. They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees.

When things heat up you re more inclined to run the air conditioner longer than you should. 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. Never try to vent a portable ac unit through a functional working chimney or fireplace that s a huge safety risk. Mini split ductless air conditioner.

When the air conditioner ran it sucked lots of hot attic air right into the room and the ceiling near those lights got to temperatures well above 100 f. In many instances an attic fan can be helpful in improving air circulation. However it absolutely must be an unused chimney in an unused fireplace. High temperatures inside your attic shorten the life span of shingles.

A portable air conditioner is the easiest solution for cooling your attic. Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape. 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.
