Anyone on here or can anyone recommend someone to do a Manual J load calc? This is for my remodel I am doing so the duct work is already in place. I sent the info to my local HVAC supplier who does the calcs but I have a feeling they are still going to be way oversized. Any help is greatly appreciated.
