Air Conditioner
ajaxstroud23 asked:

I have a brand new house and all summer long have had problems with my air conditioner. I was in my attic tonight and noticed that there is cold air blowing hard (harder than it blows out of the vents in my house) out of the PVC drain pipe. The pipe comes out of the AC unit and T’s immediately. The bottom portion of the T forms a “U” and then runs Parallel with the ground and goes out of the attic. The top portion of the “T” is open and that is where the extremely cool air is blowing out.

The unit is a 3 ton, 12 SEER American Standard. 1800 Sq Ft House.
What vents do you think are closed? The vents in the house are open and on one end of the house air blows fairly strong. The other end air blows very weak. I’m not sure what vents you think are closed, please explain.
I think capping it would be a huge mistake if it did get plugged up. Any other ideas?
That still doesn’t explain why the air is coming from the PVC pipe. Even without the dampers set, would the air just blow harder out the other end of the house? Should air be blowing out the drain pipe? I went in my neighbors attic and his wasn’t blowing out the drain pipe.
