goodman furnace blower
how do you determine how much cfm is best? i just bougt a 90 thousand btu furnace that can go from 1200 cfm to 2000 . i did a mannual j calculation for my house .my house heat loss is 70 btu/h and my heat gain is 30 thousand. i have a 3 ton condenser and a 4-5 ton evaporator coil that came with the package. i just want to make sure i choose the right amount of cfm to begin sizing the ductwork. is the cfm decided by the cooling needed or something like that? thanks for the help

Take a class in duct design and do yourself a favor.
