First off, I just found your site and it what a great resource! I'm finishing my basement and I've been trying to cobble together info on HVAC from all over the web, but I have found all the best info in one spot! I have purchased the cold air return and low heat instructions and should be putting them in next weekend.
So as I was hunting around the site some more, I saw the Leaking PVC quiz. I have this EXACT same issue! I would take a picture, but it would look exactly like the one on your site. It was much worse when the heat was on in the winter, but there is still the occasional drip.
Please let me know how I can fix it, thanks!

Tap Takeoff into the Existing Duct
Hello Ed,
I am installing a partition wall between the mechanical room and the semi-finished part of the basement. The semi-finished part has carpet, painted walls. But, I do not intend to install ceiling.
I want to tap into the existing duct work for air-conditioning / heating.
Since there will not be any ceiling, I could just use a round pipe and elbow to blow the incoming air from the top. For the return I need to install something in the wall yet to be built. I am not familiar with all of different types of ducting parts and tools. Therefore, I was hoping that your website could be useful.
Any help will be appreciated, even if it costs.
Thanks

Duct Span Removal
On this page you can find a detailed explanation on how to remove span of duct and how to put it back on.
This page has 3 pictures on it. Price for the instant access to the page is only $2.50.
On this page you can find an answer to this question:
Hello, Ed!
I am doing some structural work in my basement and the only way to get in the steel is to take down a span of ductwork, or to cut it. It looks like I can take out the piece I need to, it's about 3 feet long, on one end is an elbow that turns it upstairs through the floor, and the other end joins a larger network that comes from the furnace.
I'm not afraid of home repairs, but I am a novice when it comes to HVAC. Is this something I should be able to swing on my own? If so, how do I go about removing the bands that connect the pieces, removing the piece I need to get out of the way and later reconnecting it?
