Greetings, I have a question about adding a ruturn just for winter.
I live a small ranch in North Texas where it is mostly hot but we get some freezing. My HVAC has two returns both located near the floor in hallways. The only thermostat is in the living room where I have a wood burning stove. In the winter when I run the stove, it gets nice and warm in the LR but the bedrooms freeze.
I think that my problem could be solved with adding a return up on the sidewall to the living room. The idea is that I would draw the warm air from the livingroom instead of from the cool hallways. The downside would be that it would be very difficult to change any filter there.
Also, our HVAC guy told us we should leave the fan on "on" instead of "auto" so we have done this for the past few months. Is this a good idea?
