πŸ’‘ How Much Does a New HVAC System Cost?

HVAC costs depend on system type, home size, and whether existing ductwork is reused. Central AC replacement: $5,000–$8,000. Heat pump: $6,000–$10,000. Gas furnace: $3,500–$6,000. Ductless mini-split: $3,000–$8,000 (1–4 zones). Full system (AC + furnace): $8,000–$15,000.

Ductwork adds $2,000–$5,000 if new or replacement is needed. Mini-splits avoid this cost entirely. System sizing is critical β€” oversized units short-cycle (wasting energy), while undersized units run constantly. A Manual J load calculation ($100–$300) ensures proper sizing.

1,500 sq ft home, central AC: $2,250 equipment + $3,000 installation + $2,000 ductwork = $7,250 total. Mini-split (no ductwork): $3,750 equipment + $3,500 install = $7,250.
