One of the most frequently asked questions by homeowners is: How Much Does An New AC Unit Cost? Let’s explore everything you need to knows.
The Real Cost of a New AC Unit in 2025
The price of a new AC unit can vary significantly depending on several factors, including the type of system, the size of your home, and the complexity of installation. Here’s a breakdown of the average costs homeowners can expect this year:
| System Type | Unit-Only Price | Installed Cost (Incl. Labor) |

Important: These are general ranges. Actual prices depend heavily on your location, choice of brand, and specific home needs.
What Determines the Price of Your AC Unit?
1. Type of AC System
The system you choose makes a big difference. For example:
- Central AC systems are ideal for whole-house cooling but require existing duct-work.
- Mini-splits work well for additions or homes without ducts.
- Window and portable units are low-cost options but limited in capacity.
2. Cooling Capacity (Tonnage)
Your AC must be the right size for your home. Too small, and it won’t cool properly. Too big, and it wastes energy.
| Square Footage | Recommended Tonnage | Estimated Installed Cost |
| 600 – 1,000 | 1.5 – 2 tons | $3,000 – $6,000 |
| 1,000 – 1,500 | 2 – 2.5 tons | $3,500 – $6,500 |
| 1,500 – 2,000 | 3 – 3.5 tons | $4,000 – $8,000 |
| 2,000 – 2,500 | 4 – 5 tons | $6,000 – $10,000 |
3. Energy Efficiency (SEER2 Rating)
Higher-efficiency units cost more up front but lower your utility bills. Look for a SEER2 rating of at least 16 if you want the best balance between cost and savings.
4. Installation Factors
Things like the layout of your home, accessibility, and whether or not you have existing duct-work can change your quote significantly.
- Adding or replacing ductwork: +$2,000–$5,000
- Electrical upgrades: +$500–$2,000
- Thermostat replacement: +$150–$500
5. AC Brand
Top-tier brands charge more, but often deliver better warranties, longer life, and advanced features.
| Brand | Typical Installed Cost |
| Trane | $6,000 – $12,000 |
| Lennox | $6,000 – $11,500 |
| Carrier | $5,800 – $10,500 |
| Rheem | $4,500 – $8,500 |
| Goodman | $4,000 – $7,500 |
Regional Price Variation
Location matters. For example: Many homeowners researching AC Replacement Arizona services will notice higher-than-average prices due to climate demands and installation complexities in that region.
- Hot climates (like Arizona or Texas): Higher demand drives up prices.
- Cooler states: May see lower installation rates.
- Urban areas: Labor rates tend to be higher than in rural settings.
7. Federal and State Rebates in 2025
Thanks to updated energy-efficiency incentives, homeowners can enjoy considerable savings:
- Federal Tax Credit: Up to $2,000 for systems with SEER2 ≥ 16.
- State-Specific Rebates: Many states offer extra credits or utility company rebates.
- Inflation Reduction Act Programs: Still in effect; check local availability.
Cost Breakdown of Installation
Here’s how a typical central AC installation bill might look:
| Item | Estimated Cost |
| New AC Unit | $2,000 – $6,500 |
| Labor & Technician Fees | $1,500 – $3,500 |
| Permits & Inspections | $100 – $500 |
| New or Updated Duct-work | $2,000 – $5,000 |
| Thermostat | $150 – $500 |
| Electrical Work | $500 – $2,000 |
| Removal of Old Unit | $100 – $300 |
When to Replace Instead of Repair
- Sometimes repairs just aren’t worth the money. Consider replacement if:
- Your system is 10–15 years old
- Your AC uses R-22 (banned refrigerant)
- Repairs exceed 40% of the unit’s value
- You’re facing repeated breakdowns
Cost-Saving Tips
- Always get 2–3 quotes from certified HVAC companies.
- Avoid oversized systems – Bigger isn’t better in HVAC.
- Combine AC and furnace upgrades to qualify for combo discounts.
- Apply for every available rebate and credit.
- Schedule off-season installation (spring or fall) to save on labor.
