No heat from floor registers
You just reminded me of a mod I did to increase the air flow on our current FW.
Our bathroom vanity is near the furnace. I noticed that the vanity door would get sucked closed when the furnace was operating. So I added an additional return air register and air flow improved to the hot air registers.
