Attic Too Hot For Ac

Hang an outdoor thermometer in your attic making sure its range reaches at least 130 degrees fahrenheit.

Attic too hot for ac. 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. We live in south east texas. 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.

In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth. An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be. 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. 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.

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 pencil and paper next to the thermometer and record the outdoor and attic temperatures.
