Central Air Conditioner Prices by Type
Central air conditioners cool your entire home from one unit through a series of ducts that vent into the rooms. There are two types: split and packaged systems. Split systems are the most common and are likely found in most homes and buildings. Packaged systems may be used in smaller spaces but often at a higher cost. Both types effectively cool your home but differ in costs and installation. Additionally, it is possible to package your furnace and AC together, which can be a space saver for small residences, although not recommended for most homes.
Below are the average costs for the three central air conditioning system types in the most common sizes of 3 to 3.5 tons:
Unit Type | Average Cost (Unit Only) |
Split System | $4,940 – $10,010 |
Packaged AC System | $5,200 – $11,050 |
Packaged HVAC | $11,960 – $14,040 |
Split AC
A split system AC costs between $4,940 and $10,010. This system is the most economical if you already have a furnace and ducts in your home and simply want to add air conditioning. It consists of an outside condensing unit and an evaporator and fan, which sit on top of your furnace and use its air handler and ducts. This unit has a silent performance since the evaporator and fan are outside the room, removing most of the noise. If your furnace is fairly new and your ducts are less than 15 years old, this is a good way to install AC and save money. If you do not already have a furnace and ducts or need a new furnace and replacement ducts, an all-in-one package can cut down on installation costs and additional parts.
Packaged AC Unit
The cost of a packaged AC unit averages $5,200 to $11,050. This is a less common central air unit but is a good option if you already have a furnace and are just adding air conditioning but do not have much space. Instead of having two pieces connected by a tube, this is one unit that sits outside. It also uses ducts like a split system but takes up less space. This system requires more maintenance than a split system because it is completely outside. If one component breaks, the entire unit is more difficult to repair and often needs replacement.
HVAC Package Unit
The cost of an HVAC packaged unit ranges from $11,960 to $14,040. These units package a furnace and air conditioner in one unit. If you have no furnace or your furnace is older and needs replacing, consider using a packaged system that incorporates all the components of the HVAC system into one outdoor unit. These use ducts but have some of the easiest installation because it is one unit.
Central AC Unit Prices by Brand
The brand of the air conditioner plays a significant role in determining the cost. Some brands may use the same coils and internal parts but have different prices due to longevity, name recognition, or overall quality. Researching brands before purchasing is crucial as higher prices do not always equate to better quality. Below are the average costs for a 3-ton unit from the most common brands:

Central AC Prices by Efficiency
The efficiency of your unit, or how much energy it converts to heating or cooling your home, impacts costs. More efficient units have higher prices than less efficient ones. Previously, units were labeled with a SEER rating (Seasonal Energy Efficiency Rating), where a higher SEER meant lower energy costs but a higher initial cost. In 2023, the industry is transitioning to SEER2, a more accurate testing method, with new ratings about 4.5% lower than the old ones. While new units may seem to have lower efficiency ratings, they are actually more efficient. Most manufacturers list both SEER and SEER2 on labels for easier comparison. The SEER recommended for your home depends on your energy needs and climate. In cooler climates, a standard SEER may suffice, but in hotter climates, a higher SEER can help reduce energy costs with increased use. Below are the average costs for 3-ton units of varying efficiency levels:
SEER / SEER2 | Efficiency | Average Cost (Unit Only) |
14 / 13.4 | Standard (North) | $2,990 – $6,084 |

Cost to Install Central Air With No Existing Ductwork
If your home doesn’t have existing ductwork, you can still install central air conditioning, but it will involve additional steps and costs. Installing central air in a home without existing ducts is known as a retrofit. Retrofitting new ducts into an existing space is significantly more labor-intensive and costly than installing them in new construction or replacing existing ducts.
This is because the ducts need to be fitted into areas that weren’t originally designed for them, such as closets, beneath stairs, and other tight spaces.
The total project cost for installing a new central air unit and ductwork typically ranges from $6,565 to $13,910 for the AC unit and installation. Additionally, the cost of new ductwork, including labor and materials, ranges from $4,680 to $12,350. This makes the average cost of installing a 3-ton unit with ducts in a 2,000 sq. ft. home approximately $11,245 to $26,260 for a retrofit installation. If you require a larger or smaller unit, or if your home needs a more extensive duct system, the costs could vary. Consulting with HVAC professionals will provide a more accurate estimate tailored to your specific needs and home layout.
Cost to Install Central Air by Location
The cost to install central air conditioning can vary greatly depending on the type of home and its specific requirements. In an apartment building, for example, central air may need to serve multiple units, requiring larger and more expensive systems. For condos, the costs can vary depending on whether the system is being installed for all units collectively or just one individual unit. The presence or absence of existing ducts also significantly impacts the overall cost, especially in older homes and buildings where ducts might not be present, leading to higher installation expenses.

Mobile Home
The cost of installing central air in a mobile home ranges from $4,745 to $9,750. Most mobile homes require an AC unit between 1.5 and 2 tons. However, if your mobile home doesn’t have existing ducts, installing them may be impractical due to space constraints. Many mobile homes lack the necessary space to retrofit ducts, making ductless, mini-split, or window units a more viable option. If ducts were installed at the factory, central air can be run along those lines, though costs will vary depending on the duct size and condition. It’s crucial to ensure the duct system is A/C-compatible and that the mobile home has an exterior 220-volt power outlet before proceeding.
Old House
The average cost to install central air in an old house ranges from $11,245 to $28,600 for a 3-ton unit with between 180 and 300 feet of ducts. Older homes are less likely to have pre-existing ductwork, requiring installation before adding central air conditioning. The cost depends on how easily ducts can be installed, which involves running them through closets, between floors, or in attics and crawl spaces. This can expose those areas to moisture due to condensation, which is inherent with central air systems. Retrofitting ducts in older homes is labor-intensive, contributing to higher costs.
Condo
Installing central air in a condo averages between $22,425 and $93,600. Condos are shared spaces where individual units are owned separately. The lowest costs are typically achieved when multiple unit owners band together to install a central air system in common areas. However, this can be expensive due to the complex layout of many condo buildings. Many condos might be better suited for ductless AC or window units unless the building was originally designed with central air conditioning in mind. Collective efforts can reduce individual costs but require coordination among unit owners.
Apartment
The average cost of installing central air conditioning in an apartment ranges from $74,750 to $234,000. Central air provides consistent and comfortable temperatures and cleaner air, thanks to its filtration systems. Apartment buildings generally need built-in ducts from the start, as retrofitting them later can be very costly. Adding ducts after construction requires them to run through the entire building, often necessitating the use of storage or closet spaces, which can introduce moisture issues due to condensation. Installing central air in multiple units simultaneously is more cost-effective than doing it for a single unit.
Central Air Replacement Cost
When replacing an air conditioner, your existing ductwork is usually left intact, requiring only minor modifications or repairs. Similarly, the concrete pad where your unit sits may remain unless it’s damaged and needs replacing. You will typically pay an additional fee of around $195 to $325 for the removal and disposal of your old unit.
Including the new unit installation, this fee, and any necessary modifications or repairs, the average replacement cost for a 3-ton system ranges from $7,150 to $13,000.
However, if your ductwork is very old or significantly damaged, requiring partial or complete replacement, the overall cost will increase. In such cases, you can expect to pay between $9,750 and $20,800. Generally, air conditioners last between 10 and 20 years, and ducts can last just as long or even longer with regular maintenance. If your air conditioner is over 15 years old, replacing it can help lower your energy bills, especially if you live in a warmer climate where the system is used more frequently.
Replacing a Furnace and Central Air
If you need to replace both your furnace and central air conditioner, it’s often more efficient to hire one company to handle both tasks. This can sometimes result in better pricing on materials, labor, or both. If your ducts are in good condition, the cost of replacing the air conditioner alone is around $7,150 to $13,000. Replacing the furnace typically costs between $2,600 and $14,300. Therefore, replacing both systems together will likely cost between $9,750 and $27,300.
If new ductwork is needed, the project cost increases. In such cases, you can expect the total cost to be between $12,220 and $35,100. This higher cost accounts for the additional labor and materials required to install new ducts, ensuring the efficiency and longevity of your new HVAC system. Regular maintenance and timely replacements can help keep your home comfortable and your energy bills manageable.
Conclusion
