HVAC – Zoning
~4100 sf new construction outside of Houston, and planning for a normal split system design. One 3-ton and one 4-ton is what the HVAC contractor recommends. We’d like 3 zones: 1) for open social areas living/dining/kitch on first floor, 2) for 3 bedrooms including master on first floor, and 3) for 700 sf upstairs that has a bedroom and office.
I’m getting mixed advice from the contractors on zoning. One says to have the larger unit support zones 1 and 2 and is dead set against zoning across floors, and the other is recommending the larger unit support zones 2 and 3.
Does this matter? TIA
