Manual S & Fujitsu Equipment Selection Zone 3A
I’m replacing an absolutely clapped out old 2 ton package heat pump & leaking ducts with a ducted mini split & moving duct work from a vented crawl space to a vented attic. I’ll be adding a little square footage in the future & of course improving insulation & air sealing as I can(plenty of room for improvement). I had about settled on a Fujitsu AOU24RGLX outdoor unit paired with a AMUG24LMAS air handler. The best I could do for a manual S is the one from loadcalc.net & I was surprised to find that the system I’ve selected is not sufficient.
Obviously, I don’t want to oversize the system & latent capacity is a big concern here. Can someone get me pointed in the right direction? I could also use some guidance in understanding how the CFM numbers from my manual J(attached) play in to equipment selection & duct design.
