Attic Too Hot For Ac

An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be.

Attic too hot for ac.

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. 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. In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth. 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.

And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature. Having a properly vented attic is the best way to keep attic cool because it allows the hot air to escape during the summer. Hang an outdoor thermometer in your attic making sure its range reaches at least 130 degrees fahrenheit. Furnace coil and ducts are in the attic in a very hot environment apparently somewhere in the furnace the air gains 4 to 5 degrees and maybe 1 or 2 degrees more in the ductwork.

If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage. An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate.
