PVC fittings for HVAC
I am not an HVAC man so bear with me if I get the terminology wrong in my questions. The home has a Kenmore split unit which does a good job of heating the lower portion of the home. The system uses the metallic looking tubing to deliver heat and air, however the two rooms upstairs were never connected to the system for one reason or another. I want to run pvc tubing to the rooms. I once saw a show that did this and they had adaptors to connect to the existing tubing and then to pvc but that is all I remember about it. Will someone help me identify the company that makes these adaptors and also help me along with what kind of pvc pipe I will need as well as any other helpful advice?

Welcome Reddoorinc,
I'm not familiar with the product you are referring to but regardless of what you use you will need to ensure your present system has enough capacity to cool the added area.
Heating is fairly forgiving but if you add a/c to this area and the system cannot handle it you might no longer be happy with the cooling on the lower level.
The first thing to be done is a cooling load calculation to make sure that your present a/c unit has enough cooling capacity to be able to properly cool the upstairs.
If you get a quotation from a reliable a/c contractor you will have some idea of what is involved.

I agree with Gregs load calculation suggestion, but --
Look for someone who will use the Manual J load calculation method from ACCA (Air Conditioning Contractors of America). If they just try to tell you that you need this many tons of capacity because you have this many square feet or this many rooms, blah, blah, blah, then send them packing.
A proper load calculation takes into effect how big the rooms are, which direction they face (N,S,E,W), how big and how many windows they have as well as are they double pane, single pane, gas filled, energy efficient etc. It takes into account how much insulation is in the ceiling as well as in the walls and the floors (if over a crawlspace) as well as are the walls 2x4 or 2x6 thickness.
Anything else is just a WAG (wild-asp-guess)
