[r247yan]

hey guys & gals..

i have been doing installs/ service etc for approx 10 yrs.. i did some add-on duct work etc.. here is my problem at my own house i need to have a return up stairs.. i have a all the materials but ran into a problem.. coming up through the floor and need about 20 inches to get flex up. but the house was built back in 1922.. i have only 6 or so inches.. ( floor joists etc in way.. i heard of panning in the joints and just using them as a return.. is there any web site or info i can recieve to help me.. it is almost 8 degrees warmer up stairs than down.... any help would be nice.. sorry no pics.. i dont have any fancy camera.. im still in the dark ages..

If it's warmer upstairs in cooling,with all the doors open so air can get back to the return,you need more supply air ,not return.

Be sure before you add the return.

If you need more supply,and can increase the size,look at improving the flow,better fittings,near the indoor unit ,and adding attic and kneewal insulation to reduce the load.


Actaully adding insulation is a better thing to do first,as it can help,and reduces operating cost..
