Placemnt of air handler
I am planning to build a 950sq ft guest house. The condensor will be on a slab outside the house. I am trying to save space by placing the airhandler in the attic. The attic area will be insulated with Icenyne (Zip Foam). I was informed that moving the airhandler into the attic a higher seer rated unit is needed and the cost of placing the whole HVAC unit would increase by about 1/3. Does this seem reasonable?
