Thanks, I've posted in several ng and never had a problem getting help from
professionals. Fortunatly, there are nice people just about everywhere you
look. I'm not an angel either but that guy has some anger issues he needs to
work out. My first thought was. If he's such a expert in the field, why is
he wasting his time cussing out nubees in a ng? Uh... did he not see the
"stupid nubee question" in the header? Really, I was hoping he'd keep after
it. I kind of get a kick out of seeing just how far they will go. He sounds
like he is headed for a coronary or stroke.
I suspect you're right on with my attic fan because even when it's running
it's unbelievably hot in there. I'll look into the film barrier. A lot of
people here (central TX) have ridge vents installed. That's not cheap either
from what I understand.
If the a/c breaks down it's covered under my home owners warranty. If I call
a guy out here to look at it and there isn't anything wrong with it it's my
expense. I thought maybe there was something I could check. As long as it's
working, as well as it is now, I'll try to ignore the noise. I hoping it's
not bothering my neighbors.
Thanks again
Jim
