HVAC system pricing is a baseline estimate. HVAC work must be verified by a licensed HVAC contractor. Verify Manual J/load calculation, equipment sizing, duct design, refrigerant line set, electrical requirements, gas/furnace requirements, condensate drain, float switch, attic access, service platform, permits, inspections, local code requirements, and subcontractor pricing before final use. This scope may overlap with room-level HVAC registers, bathroom exhaust fans, laundry dryer vents, thermostat items, exterior condenser/electrical items, and ceiling repair items.

Use this section when estimating house-wide HVAC replacement, ductwork, registers, returns, thermostat, and system startup instead of room by room.
HVAC pricing changes significantly based on tonnage, Manual J/load calculation, attic access, duct condition, equipment location, electrical requirements, refrigerant line condition, drain routing, permits, and code.
HVAC work must be verified by a licensed HVAC contractor.
