Supply line register in vented attic
I recently moved to Georgia and had new HVAC systems installed in my 15 year old house. The main floor and basement have a zoned system that works great. The 2nd floor has an attic unit but has a hard time keeping the rooms cool when it get’s into the 90s outside. I have a vented attic that gets extremely hot. I had a thought on a possible solution but wanted to get some input…
One of the attic ducts feeds a chase that brings cold air to a register in the 1st floor living room. This doesn’t make sense to me because there is no issue with keeping the 1st floor cool. Instead of feeding cool air downstairs, if I redirected this duct to a register in the attic would that help create a positive pressure to push the hot air out the ridge vents and to help keep the 2nd floor cooler?
