How much does it cost to replace a heat pump? Nationally, a heat pump replacement typically runs $5,525 – $7,475 installed for a 3-ton standard-efficiency system. Your final price depends on size, efficiency tier, add-ons and local labor rates. The calculator below is pre-set to a heat pump — adjust it for your home.
💵 What Will a New HVAC System Cost?
Estimate the installed replacement cost of a new central AC, heat pump, gas furnace, full system, or mini-split in the US. Adjust for size, efficiency, add-ons (ductwork, removal, permits) and your region to get a realistic price range — before you call a contractor.
🛠️1. System Type
Pick the system you are replacing. "AC + Furnace" is a full split-system swap (both units at once).
📏2. System Size
Range: 1.5 – 5 Tons (cooling). A typical home is 2–3.5 tons.
⚡3. Efficiency Tier
Higher efficiency (SEER2 / AFUE) costs more up front but lowers running bills. Premium tiers are usually variable-speed / inverter.
📍4. Region
Labor rates vary a lot by metro. This scales the estimate to your area; pick National for a baseline.
➕Add-ons & extras (ductwork, removal, permits) — optional
Heat Pump Replacement Cost by Size
Typical US installed price ranges at standard efficiency. Bigger equipment costs more; high-efficiency models and add-ons push these higher:
| Size | Estimated Cost (installed) |
|---|---|
| 2 ton | $4,700 – $6,350 |
| 3 ton | $5,525 – $7,475 |
| 4 ton | $6,400 – $8,650 |
| 5 ton | $7,175 – $9,725 |
What’s Included in a Heat Pump Replacement
A quote covers equipment (the unit itself) plus labor, and often add-ons: old-system removal, a new line set, electrical or breaker work, permits and inspection, and sometimes new ductwork. Equipment is usually 45–55% of the total and labor the rest. High-efficiency models cost more up front but lower running bills and may earn rebates or tax credits. Use the calculator above to add the extras your job needs.
Frequently Asked Questions
How much does heat pump replacement cost? Nationally, expect about $5,525 to $7,475 installed for a 3-ton standard-efficiency unit. Size, efficiency, add-ons and your local labor rates move the final number.
What makes Heat Pump quotes vary so much? The biggest swing factors are add-ons (ductwork, electrical, removal, permits), the efficiency tier, equipment brand, and local labor rates. Always compare line items, not just the bottom line, and get three quotes.
Is a high-efficiency Heat Pump worth it? Often, over time. It costs 20–45% more up front but cuts energy bills every month and may qualify for utility rebates or federal tax credits, with payback frequently in 4–8 years.
