Any suggestions? The house is about 20 years old. Also, I'm
trying to avoid tearing up the roof.

I have same problem. HVAC guy said it would cost a fortune to set up
ductwork and fans to correct. Since there are only 2 of us, wife is
thinking about getting a portable AC. I don't want to stick one in
the window. Maybe others can comment.

I bought and installed a 110v window unit in the bedroom.

It cut my power bill by 2/3rds.

Honest - from $240/month to $80.

Think on it; why cool the whole house for the twelve hours a day you're
sleeping?
