When summer rolls in hot and heavy, the question I hear most from homeowners is simple: “How much is AC, really?” Whether you’re replacing an old central air system or putting in cooling for the first time, understanding what drives the average cost of central air conditioning can help you plan smarter — and save money long-term.
I’ve worked in HVAC for over two decades, and I’ve seen prices swing wildly depending on home size, energy efficiency, refrigerant type, and even installation quality. The truth is, the central AC cost you’ll pay isn’t just about the sticker price — it’s about what’s behind it.
So, let’s break it all down: from equipment pricing to installation, warranties, and modern refrigerants like R-32 that can make your investment pay off over time.
The Average Price of an Air Conditioner in 2025
According to data compiled by Energy.gov, the average cost of central air conditioning in the U.S. generally ranges from $4,000 to $12,000 installed. That’s a big range — and for good reason. The price you pay depends on several factors:
-
System size (in tons) – Larger homes need higher-capacity systems.
-
Energy efficiency (SEER2 rating) – More efficient systems cost more upfront but save more on energy bills.
-
Refrigerant type – Modern refrigerants like R-32 are cleaner and more efficient, but some brands still charge more for older, phased-out blends.
-
Ductwork and installation complexity – Adding or replacing ductwork can increase your total cost significantly.
If you’re asking “how much does AC cost?”, here’s a quick breakdown of typical equipment-only prices by system size:
| System Size | Typical Home Size | Equipment Cost (Average) | Installed Cost (Average) |
|---|---|---|---|
| 2 Ton | Up to 1,200 sq. ft. | $1,800 – $3,000 | $4,000 – $6,000 |
| 3 Ton | 1,200–1,800 sq. ft. | $2,200 – $3,500 | $4,500 – $7,000 |
| 4 Ton | 1,800–2,400 sq. ft. | $2,800 – $4,200 | $5,500 – $8,000 |
| 5 Ton | 2,400–3,000 sq. ft. | $3,200 – $4,800 | $6,000 – $9,500 |
These are averages — you’ll find some systems lower, especially if you shop through online distributors that sell direct to homeowners.
One great example is the Goodman 3 Ton 14.5 SEER2 R-32 Bundle. It’s a reliable, efficient setup that offers modern R-32 refrigerant performance without the inflated cost of big-name showroom systems.
How Much to Get Central Air Installed?
Installation costs can often equal or even exceed the price of the equipment itself. Most homeowners spend between $4,000 and $9,000 for a complete central AC installation, depending on whether existing ductwork can be used.
If you already have a furnace and ducts in good condition, you’ll pay much less — possibly as little as $2,500 to $4,000 for labor. But if your home needs new ducts or major electrical upgrades, costs can climb fast.
Here’s what’s typically included in the installation portion of the central AC cost:
-
Site evaluation and load calculation
-
Indoor coil or air handler setup
-
Outdoor condenser installation
-
Electrical wiring and breaker installation
-
Refrigerant line setup and pressure testing
-
System charging with refrigerant
-
Startup, calibration, and testing
It’s worth noting that federal regulations now require SEER2-compliant systems, meaning higher baseline efficiency — which can affect pricing and available models.

How Much Does AC Cost to Operate?
The average cost of central air conditioning isn’t just what you pay upfront. You also need to think about long-term energy costs.
The U.S. Department of Energy estimates that air conditioning can make up about 12% of total annual home energy use, depending on climate and system efficiency. With electricity costs rising, every point of SEER2 efficiency can make a measurable difference.
For example:
-
A 14.5 SEER2 system (like Goodman’s R-32 line) can save hundreds annually compared to older 10 SEER models.
-
A 16–18 SEER2 unit costs more upfront but can reduce electricity use by up to 20%.
If you want to compare different efficiency ratings, the ENERGY STAR central air calculator is a great resource that shows how efficiency impacts energy use and long-term savings.
What Impacts the Average Price of an Air Conditioner
Let’s break down the main things that affect your central AC cost:
1. System Size (Tonnage)
Each ton of cooling represents 12,000 BTUs. Bigger isn’t always better — oversized units short-cycle and wear out faster. A professional Manual J load calculation ensures you get the right tonnage.
For most homes:
-
2 ton = small condos or apartments
-
3 ton = medium-size homes
-
4–5 ton = larger single-family homes
2. Efficiency Rating (SEER2)
SEER2 replaced the older SEER metric in 2023, and systems must now meet new regional minimums. While 14.5 SEER2 is a great mid-range value, going higher can pay off over time in hot climates.
3. Refrigerant Type
R-32 refrigerant systems are quickly becoming the new standard. They’re up to 10% more energy-efficient and have a significantly lower global warming potential than R-410A. According to Daikin, R-32 is classified as a mildly flammable A2L refrigerant, safe for residential use under current codes.
Choosing an R-32 system today can also future-proof your home against refrigerant phase-outs and price spikes down the road.
4. Brand and Warranty
A big brand name doesn’t always mean better performance. Many systems — including those sold under premium labels — are built with the same internal components as budget-friendly lines. What matters most is reliability and warranty coverage.
Goodman systems, for example, are backed by industry-leading limited warranties and have a solid reputation for durability and value.
Comparing Equipment: How Much Is AC by Type
Not all AC systems are built the same. Here’s a quick guide to how costs differ by system type:
| Type | Typical Cost Range | Notes |
|---|---|---|
| Central Split System | $4,000–$9,000 | Most common; uses ductwork |
| Ductless Mini Split | $2,000–$7,000 | Ideal for homes without ducts |
| Heat Pump | $5,000–$10,000 | Provides heating and cooling |
| Packaged Unit | $3,500–$8,500 | All-in-one system, great for limited space |
Each setup comes with pros and cons. Central systems are great for whole-home comfort and even cooling. Mini splits give you room-by-room control but may cost more per zone.
If you want an all-around balance between price, performance, and environmental responsibility, a central R-32 system like Goodman’s 14.5 SEER2 bundle hits that sweet spot.
The Long-Term Value of R-32 Systems
We can’t talk about the average price of an air conditioner without looking at what makes modern systems better. R-32 refrigerant isn’t just a trend — it’s the future of residential HVAC.
-
Higher efficiency – Requires less refrigerant volume to achieve the same cooling.
-
Lower environmental impact – Roughly one-third the global warming potential of R-410A.
-
Lower long-term maintenance costs – Compatible with newer compressors and coils designed for longer life.
As global standards shift toward sustainability, R-32 units will continue to dominate. Choosing one now means fewer headaches later when older refrigerants become scarce or expensive.
How to Budget for Your Central AC Replacement
When planning your budget, it helps to separate equipment, installation, and optional add-ons:
-
Equipment: $2,000–$4,500 average (for mid-efficiency R-32 systems)
-
Installation: $2,000–$5,000 average
-
Optional items: smart thermostat, new ducts, or zoning controls ($500–$2,000)
You can use the average cost of central air conditioning table above as a guide, but don’t forget to factor in future savings. High-efficiency systems can reduce annual cooling costs by 15–30%, which adds up over 10–15 years.
Why Goodman Systems Offer Real Value
The Goodman name has long been synonymous with reliable, American-built HVAC systems at reasonable prices. Their 3 Ton 14.5 SEER2 R-32 Bundle is a perfect example of balanced performance and affordability.
It gives homeowners access to:
-
Proven compressor reliability
