Why Should You Consider a Central AC Replacement?

While expensive, central AC replacement is a purchase that has long-term effects. For example, replacing your central air conditioning can give you ten years of service. Not only that, in the long run, you’ll save money.


Newer central AC units are more energy-efficient. Not to mention, using an outdated AC can lead to other issues, including:

  • Low refrigerant can cause your unit to work harder to cool your space
  • Normal wear and tear causes your unit to run less efficiently
  • Ice build-up on the evaporator coils
  • Electrical issues and failures
  • Issues with AC fans
  • Poor air quality

Does it make sense to pay more money for less air quality? We don’t think so.

How Much Does Central AC Replacement Cost?

The national average for AC replacement costs somewhere between $3,800 and $7,500. That doesn’t include ductwork. While that seems steep, it’s a drop in the bucket when you compare it to a new install.

The cost to install central air conditioning averages between $5,000 and $12,500. Here’s why:

  • Labor = $400 and $2,200
  • Materials = $8000 and $6,000 depending on the type of unit you use
  • Total = $1,100 and $10,500

That’s a pretty wide range. So let’s find out why it’s so vast? First, you have the cost for the AC unit.


Depending on the brand you use, it can cost between $1,000 on the bottom and $10,000 for a high-end AC unit. Of course, another factor is the size of your home.

Here’s a price breakdown by square footage:

  • 1,000 square feet  = $3,000 and $5,000
  • 1,500 square feet  = $3,400 and $7,000
  • 2,000 square feet = $4,000 and $9,100
  • 2,500 square feet = $5,070 and $9,065
  • 3,000 square feet = $6,800 and 12,000

That works out to $25 to $60 per square foot. However, these prices factor in installation for both heating and cooling. So if you’re only getting AC, it may cost less.

The size of your AC unit can also affect the price. Here’s what you’ll pay by the ton:

  • 2-ton averages $1,200 and 3,000
  • 3-ton averages $1,500 and $4,030
  • 4-ton averages $2,200 and $6,070
  • 5-ton averages $3,000 and $7,000

Central air conditioning units can also vary in price based on their SEER rating. Here’s a price comparison:

  • SEER 13 – 14 averages $3,000 and $6,000
  • SEER 15 – 16 averages $3,700 and $9,000
