💰 Average Heat Pump Installation Cost in 2025
| System Size (Tons) | Total Cost Range (Standard Efficiency) |
|---|---|
| 1.5 – 2.0 Ton | $6,500 – $9,000 |
| 2.5 – 3.0 Ton | $8,500 – $13,000 |
| 3.5 – 4.0 Ton | $10,000 – $15,000 |
| 5.0 Ton | $12,000 – $18,000+ |
🛠️ The Goodman 3 Ton GLZS4BA3610 system typically falls between $8,900 and $12,500 for a full install, depending on ductwork, location, and whether you’re replacing a heat pump, furnace, or AC.
📍 What Factors Affect the Total Cost?
1. Climate Zone
In colder climates (Zones 5–7), you may need:
-
Cold climate heat pump upgrade (variable speed or inverter tech)
-
Backup electric heat strips
-
More insulation/duct upgrades
🌡️ Example: Installing in Chicago or Boston might cost $1,500–$3,000 more than in Florida or Texas.

2. Electrical Panel & Wiring
-
Older homes may need panel upgrades to handle the 240V electrical load of a heat pump.
-
Panel replacement = $1,200–$3,500
-
Dedicated circuit for heat strips = $300–$800
⚡ Pro Tip: Ask your electrician to pre-wire for EV chargers or solar while upgrading your panel.
3. Ductwork Compatibility
-
Undersized or leaky ducts = higher noise, poor airflow, wasted energy
-
Fixing ductwork can add $500–$2,500, depending on layout and attic/crawlspace access
🧰 Want to skip the duct headache? Consider ductless mini-splits, though they typically cost more per ton.
4. Home Size & Insulation
| Square Footage | Likely Heat Pump Size |
|---|---|
| 1,200–1,600 | 2.5 Ton |
| 1,600–2,000 | 3.0 Ton |
| 2,000–2,400 | 3.5 – 4.0 Ton |
Poor insulation, old windows, and drafty doors may require a larger system or drive up your operating costs.

-
15.2 SEER2 cooling
-
7.8 HSPF2 heating
-
Perfect balance of affordability and efficiency
⚖️ Going up to 18–20 SEER2 might save more energy but adds $3,000–$5,000 upfront.
✅ Leverage 2025 Rebates & Incentives
Thanks to the Inflation Reduction Act, federal and state programs can save you thousands:
| Program | Potential Savings |
|---|---|
| Federal Tax Credit (25C) | Up to $2,000 |

📌 Most programs require:
-
15.2 SEER2+
-
AHRI-matched indoor + outdoor equipment
-
Licensed installer + permit
✅ DIY Part of the Job (Safely)
While you should never DIY refrigerant connections, you might be able to:
-
Clear a space for install
-
Replace your thermostat
-
Handle your own duct sealing (mastic, not tape!)
🛠️ Pro Tip: Always check code compliance before touching any HVAC electrical or refrigerant components.

🏁 Final Word from Mike Sanders
“The average homeowner installing a mid-efficiency heat pump like the Goodman GLZS4BA3610 in 2025 should expect to pay $9,000–$12,500—but that number can drop fast with the right rebates and setup. Always choose an AHRI-matched system, get a Manual J load calc, and shop around for quotes. The savings over time are absolutely worth it.”
