Conducted site assessment for complete HVAC system replacement with air handler relocation from current attic position to bathroom area. Evaluated existing Carrier air handler installation, inspected ductwork that has been spray foamed, and assessed attic conditions including pink fiberglass insulation, copper refrigerant lines, and flexible duct connections. Documented current system configuration and structural considerations for proposed relocation, noting that extensive drywall removal will be required prior to final measurements and equipment sizing. Discussed two replacement options: relocating current forced air system versus installing mini-split units for upper level. Determined that load calculation will be necessary due to building envelope modifications since original installation, including white reflective roofing and spray foam duct insulation, with potential for additional insulation and spray foam application after demolition phase.
