No return vent on my second floor


I have a 1906 model Victorian style house. It is about 1700 sq feet. The furnace and coil are in a downstairs closet centrally located in the house. The air return is on the wall above closet door that contains the unit. All of the downstairs ductwork is in the crawlspace with vents in the floor, and all of the upstairs ductwork is in the attic with vents in the ceilings. There is no return air vent in the upstairs portion of the house. I have been told that there definitely needs to be one there. Is this the case?? Thanks in advance, and excuse my ignorance please.

We do a lot of Victorian style house in Dayton. Most of them had gravity furnace or coal furnace with big duct work that also did down stairs only. What we have to do most of the time is add a smaller system up stair only. That up it in attic and run new duct work for up stair only.

where does it get its return from just the raw attic...in the heating season your pulling cool attic air instead of temtered space return from the second floor.if the filter just in the attic unit just clips to the back your missing return duct work,most attic units just have a large return grill in the hall ceiling and then its flex ducted over to the back of the unit sheet metal box that screws to the back of the unit.

I apologize if I was not clear about everything. The furnace and coil is in a downstairs centrally located closet. Above the closet door, in the dining room, is the return air vent. The return air comes from the air in the dining room only. There is then ductwork running up into the attic and out to each vent in the ceilings of the upstairs rooms. There is also ductwork running down into the crawlspace and then out to each vent in the floors of the downstairs rooms. My question is, because there is no return in the upper level, does that effect my heating/cooling, and how so?? Also if it is not possible for me to install an upstairs return, are there any other options?? Thanks in advance.

ONE unit handling 1st and 2nd floors.....the stairs are the return ....the grill will pull from the nearest area if you had one down into the closet from the second it would slightly pull from there.if doors are closed at night there is no return from upstairs..need suplly into a space to have a return.houses rarely have returns in ever room $$$$ unless spec'd..as long as the grilled return in the closet isn't whistling the return is what it is....do you feel a draft coming down the stairs as you head up keeping in mind heat runs MED/LO heating HI when your cooling
