If you are in the market for a new Central AC unit, you may be wondering how much it cost. The answer to that question can vary greatly, depending on the size and type of AC unit you choose. In this blog post, we will discuss some of the factors that go into the cost of a central AC unit, as well as provide some ballpark estimates for what you can expect to pay.

System Size

The size of the AC unit is an important factor when it comes to cost. Generally, larger AC units cost more than smaller ones. This is because they have a higher capacity and require more energy to operate. AC units with more powerful features may also cost more than those that lack them. AC units range from 1.5 to 5 tons, with each ton being equal to 12000 BTUs per hour (British Thermal Units).

The larger the AC unit you install, the more it will cost. A 1.5-ton AC unit, for example, may cost around $2,500–$3,000 before installation. However, a 5-ton AC unit can cost up to $7,000 or more after installation. For a more accurate estimate of AC costs, it is best to consult a professional AC installation service in your area. They will be able to provide the best advice for finding an AC system that meets your needs and budget. 

System Type

The cost of a central AC unit varies depending on the system type and size you need. Generally, AC units fall into three main categories: split ACs, ductless mini-splits, and packaged ACs. Split ACs are typically the least expensive option and can range from $1,500 to $4,000. Ductless mini-splits are typically more expensive, costing between $2,000 and $7,000.

Finally, packaged ACs tend to be the most expensive option, ranging from $4,500 to upwards of $12,000 depending on the size and features included. The cost of installation will also vary based on the complexity of the job and the AC system you choose.


AC unit installation costs can vary depending on the size and type of AC system you choose. The AC unit itself will typically range in cost from around $3,500 to over $7,000. Additionally, installation labor costs will vary depending on the local market rate and the complexity of the AC system. 

Factors that affect AC installation labor costs include ductwork modifications, the AC system size, and type, the level of AC efficiency desired, local labor rates, and any additional components needed for installation. A professional technician can provide an estimate for AC installation costs based on a homeowner’s specific requirements. 

SEER Rating

The SEER, or Seasonal Energy Efficiency Rating, is a measure of the efficiency of an AC unit. AC units with high SEER ratings are more energy efficient than AC units with low SEER ratings and tend to cost more due to their higher levels of efficiency. 

AC units with higher SEER ratings usually cost more initially but have the potential to save you money over time in energy costs. AC units with a SEER rating of 13 are generally considered entry-level AC units.


AC’ from a specific brand can increase or decrease its cost. Factors such as quality, features, reputation, and more can all affect the price of ACs from a particular brand. High-quality ACs tend to have higher prices than those with lower quality. Furthermore, AC models that come with advanced features will often be more expensive than those without. 

Reputation is another major factor that affects AC prices, as ACs from well-known brands tend to be more expensive than ACs from lesser-known brands. Additionally, ACs from brands with a long history of producing quality ACs will often cost more than ACs from newer or less established companies.


AC warranties are a crucial factor when it comes to budgeting for AC installation, as they can significantly increase the cost of the AC. Warranties often protect against manufacturer-related issues such as mechanical defects and breakdowns. They also typically cover labor costs associated with the repair or replacement due to malfunctioning parts. 

The length of the warranty varies depending on the AC model, the AC brand, and the company that provides the AC warranty. It is important to research AC warranties carefully before purchasing an AC unit in order to ensure that you get the best protection for your investment.


AC units generally range from $500 to several thousand dollars, depending on size, type, and features. AC units with higher-quality components and warranties may cost more, while split AC systems tend to be the least expensive option. Professional AC installation can also add significantly to the overall cost of a new AC unit.

Ultimately, when it comes to AC unit cost, there is no one-size-fits-all answer. The best way to get a better idea of how much your AC unit will cost is to consult an AC professional for a more accurate estimate. This can help you make the most informed decision when it comes to selecting and installing the right AC unit for your needs.
