I have a rheem classic super quiet 80 furnace that according to manufacturer's literature, has adjustable air speed that a technician can adjust. Does anyone know how I can adjust it myself?
I'm not using some rooms and are closing the registers in those rooms to save energy. This cause the other register to blow stronger, too strong in fact.
For future reference (when I need to buy a new furnace), does any furnace maker support home owners directly? I hate to ask the installer for support since they are not necessarily the most knowledgeable.
