IdiotMachine 07/21/19 5:35:10 PM #31:	@chrono625 posted... 500sqft per ton is rule of thumb for HVAC sizing. For 6500sqft, yeah 5 ton isn't able to handle that. You should realistically have two 5 ton units for the entire house. So the HVAC guy recommended getting at least a 7-ton light commercial unit, because getting two units will involve resizing ducts, zoning, etc. (he explained it to me in more details, but I forgot now). I talked to an HVAC friend, and he said don't do that, just get a second 3-ton split ductless unit installed in my first floor (the entire first floor is an "open concept", with vaulted ceilings and ~2,000 sqft of open space). What do you think about that...? --- https://imgur.com/XNEdLrJ <cite>IdiotMachine posted [p:924994713] in PSA: Your ...
