Central air conditioning is a very effective way of cooling your entire home. While there are 4-ton HVAC units that offer other services, central air conditioning is the only type that is sized in tons and offers only air conditioning. If you have ductwork in your home, you already use a forced hot air furnace or have central air already, installing a new central air unit keeps your home cool during the hottest months of the year. If you have a larger-than-average home, a 4-ton AC unit may be the right choice. 4-ton units can come in various types and efficiencies, which impact your total costs.

The average cost to install a 4-ton central air conditioner is $6,000 to $11,000. Most homeowners spend around $8,500 on a 16 SEER split system fully installed with minor modifications to existing ducts. The low cost for this system is $5,000 for a 13 SEER split system unit fully installed with no modifications or changes to existing ducts. The high cost for this unit is $14,000 for a 21 SEER packaged HVAC unit with significant updates to existing ductwork.

4-Ton HVAC Unit Cost Calculator

4-ton air conditioning units are generally used in homes that are 3,000 sq.ft. or larger or have insufficient insulation. They can generally be found in three types. Split systems are the most common and least expensive. Packaged AC units are the least common. Packaged HVAC units combine a heat source with AC and are the most expensive. In addition, 4-ton units come in a range of efficiencies or SEER ratings, from 13 to 21. The higher the number, the more efficient the unit, and the lower your monthly bills. However, your upfront costs will also be higher for more efficient units. Below are the average costs to install a 4-ton AC unit of varying qualities.

4-Ton AC Unit Costs
Zip Code Tons
Basic Standard Best Quality
4-Ton AC Unit Cost (Material Only) $4,000 - $5,000 $5,000 - $8,000 $7,000 - $11,500
4-Ton AC Unit Installation Cost (Labor Only) $1,000 - $1,500 $1,250 - $2,000 $1,500 - $2,500
Total Costs $5,000 - $6,500 $6,250 - $10,000 $8,500 - $14,000
4-Ton AC Unit Cost per Ton $1,250 - $1,625 $1,563 - $2,500 $2,125 - $3,500

In addition to the type of unit and its SEER rating, several factors influence your final cost. These can include the area it is installed in and its ductwork. If your ducts are old or need updates, this increases your costs. Likewise, the compressor needs to be installed outside on a concrete pad 1. If you need a new pad, this increases the cost of your installation and the overall cost of your project.

Cost to Install a 4-Ton AC and Furnace

Air conditioners and furnaces use the same ducts to heat and cool your home. They may be packaged together but are frequently installed separately from one another. The average cost of a 4-ton AC unit and a furnace sized for the same area (3,000 sq.ft.) averages $10,000 to $19,000 installed. Having both installed at the same time can potentially give you a discount. Speak to your HVAC provider for more information.

Additional Considerations and Costs

  • Mounting 2. The compressor for your AC unit is installed outdoors on a concrete pad. If you need a new pad, this can increase your costs.
  • Permit. Permits may be required for this installation in some areas. Speak to your local municipality for more information.
  • Rebates. Some manufacturers offer rebates to help lower your costs. In some areas, you may also get rebates for installing a higher-efficiency unit. Speak to your installer about what rebates may be available in your area.
