Attic too hot for ac.

If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage. Hang pencil and paper next to the thermometer and record the outdoor and attic temperatures. In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth. 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.

And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature. My attic is ridiculously hot if i install a fan pull out hot air to help cool my attic will my ac work better right now it takes two to three hours to drop the house 4 degrees. As a certified licensed home inspector it is not correct to say too much ventilation is bad for an attic unless rain moisture is. 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.

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