no it is not possible...... 700 cfm does sounds hi..... I believe the lowest continous fan is 30% of 2nd stage cooling speed.... others will chime in..getting old memory failing......
I trust ya man....... but never seen one supply 150 cfm....... you know something I don'tActually it is possible. They are set from the factory for around 450 cfm for low speed. On those furnace if you look very carefully inside the viewing port on the lower door there should be a small series of red LEDs. There is a way to read the fan speed but you need to read a service manual. If I remember you count the flashes and each flash is 100 cfm and then there is a pause and it starts over again. If it is higher than 4-500 then the installer changed it and it can be put back down by flipping some dip switches.
As Carmon said, he was asking for 150. Thats why i said ain't gonna happen.No problema. 450-10% should make him Happy. Hopefully the Next Yr is a good one. Health wise the last one has been horrible. Freedom 55 cannot get here soon enough.
Thats hard to do.Thanks for the wishes. Gotta learn to calm down, stop treating myself like a dog and running around like Superman trying to solve everyones problems around me. Hopefully that happens.
