I have a question for the HVAC experts on this forum:
We live in a circa 1950's house with a conventional gas-fired forced air furnace. We are planning a total reno of the house in a few years, at which time the entire HVAC system will be upgraded. The existing furnace has a large cold air return duct drawing air from a 400 sq' room adjacent to the furnace area (see photo, arrows). This duct only returns air from this room. The duct is big, ugly and in the way of some ceiling work that needs to be done.
Interestingly, this duct runs immediately adjacent to another cold air return from another part of the house, but bypasses it and hooks into the main cold air plenum of the furnace.
I would like to remove it. Is there any reason why I could not connect it to the existing cold air return, and remove the majority of the redundant ducting? :confused:
