I am having an HVAC guy take out the duct to my 30 s.f. half bath. The room is an oven in the winter and a freezer box in the summer with the A/C on. Are there any potential problems in removing that duct? Does that mess with the pressure? Do I need to have one installed elsewhere to make up for the one coming out? Is it better to put in a smaller duct and register instead of just taking it out completey? It's flex duct and the size is 10", the duct is 10" to every register in the house.
The HVAC heat pump, air handler, A/C 3ton(trane) and duct were newly installed about eight years ago in our remodeled 1940's house which did not have HVAC previously. I now know I should've had the load calcs done first before they installed anything. They didn't offer that and I didn't know any better then. After reading on this website it looks like I should also have had a return upstairs . This live and learn stuff can get expensive. I have called the 15 or so HVAC people in our area (small town) only two people do load calcs and apparently only if you know to ask for it. sheesh.
