Harry Home owner" need feed back to match system for 2100 sq ft beach home. The current system is original builder 14 year old Trane 3 ton heat pump & air handler that is dying so has served it life span well.
XB 13 series heat pump 3 ton with a XB Hyperion GAT2A0B42S31SA 3.5 ton air handler
XB 13 series heat pump 3 ton with XR series Hyperion Tam4 air handler
XR 13 series heat pump 3 ton with XR series Hyperion Tam4 air handler either Tam4oa36 (3 ton) or Tam4a0b42 3.5 ton
The Air return will handle a 3.5 ton air handler but if move up to 3.5 tom will their be humidity issues ?
The XB is basic entry level which will do, also not to much difference between the 2 system and/or is the XR worth the extra bang for the buck.
The HVAC contractor is great, I've researched the site have not seen any negatives on these Trane models so just want to further my home work before making a decision on which system.
